OPINION

¶1 On October 13, 2009, plaintiffs, The Hope Clinic for Women, Ltd., and Dr. Allison
Cowett, filed suit in the circuit court of Cook County seeking to enjoin enforcement of the

-2-
 Parental Notice of Abortion Act of 1995 (the Act) (750 ILCS 70/1 et seq. (West 2010)).
Plaintiffs alleged that the Act is facially invalid, violating the privacy, due process, equal
protection, and gender equality clauses of the Illinois Constitution of 1970 (Ill. Const. 1970,
art. I, §§ 2, 6, 12, 18). Defendants, Manuel Flores, in his capacity as Acting Secretary of the
Illinois Department of Financial and Professional Regulation; Daniel Bluthardt, in his
capacity as Director of the Division of Professional Regulation of the Illinois Department of
Financial and Professional Regulation; and the Illinois State Medical Disciplinary Board,
moved for judgment on the pleadings (735 ILCS 5/2-615(e) (West 2010)) or, in the
alternative, dismissal of the complaint (735 ILCS 5/2-619(a)(4) (West 2010)). Stewart
Umholtz, as State’s Attorney of Tazewell County, and Edward Deters, as State’s Attorney
of Effingham County, petitioned the circuit court for leave to intervene in the matter. 735
ILCS 5/2-408(a)(2) (West 2010).
¶2 On March 29, 2010, after hearing argument, the circuit court upheld the facial validity
of the Act, granted defendants’ motion for judgment on the pleadings, and dismissed
plaintiffs’ complaint with prejudice. The circuit court then denied the proposed intervenors’
petition as moot.
¶3 Plaintiffs and the proposed intervenors appealed the circuit court’s orders. The appellate
court reversed the dismissal of plaintiffs’ complaint and remanded for further proceedings,
but affirmed the order denying the proposed intervenors’ petition to intervene. 2011 IL App
(1st) 101463.
¶4 Petitions for leave to appeal were filed in this court by the proposed intervenors in No.
112673, and defendants in No. 112704. We granted the petitions and consolidated the
appeals for review. Ill. S. Ct. R. 315 (eff. Feb. 26, 2010).

¶5 BACKGROUND
¶6 Before addressing the issues raised in this appeal, it is important to set forth the long
history of litigation associated with this case. The Illinois legislature enacted the Parental
Notice of Abortion Act of 1995 (the Act) after it repealed the Parental Notice of Abortion
Act of 1983 (the 1983 Act). See Ill. Rev. Stat. 1985, ch. 38, ¶ 81-61 et seq.; Pub. Act 83-890
(eff. Jan. 31, 1984). The 1983 Act became law on November 2, 1983, over the veto of then-
Governor Thompson. The 1983 Act prohibited “unemancipated minors and incompetents”
from obtaining an abortion unless both parents, or the legal guardian, were given notification.
A putative class of physicians who provided or sought to provide abortions filed suit in the
United States District Court for the Northern District of Illinois challenging the
constitutionality of the 1983 Act under the federal constitution. See Zbaraz v. Hartigan, 584
F. Supp. 1452, 1454 (N.D. Ill. 1984) (Zbaraz I).
¶7 The federal district court, after reviewing relevant federal case law, held the 1983 Act to
be constitutionally defective because: (1) it required a waiting period of at least 24 hours
after notice was given to the minor’s parents; (2) the judicial procedures for obtaining a
waiver of the notification requirement, i.e., the “judicial bypass” procedures, failed to
provide for expeditious appellate review of notification decisions; and (3) the judicial bypass
procedures did not assure the minor’s or the incompetent’s anonymity at either the trial or

-3-
 appellate level. Id. at 1459, 1461-62.1 Although the plaintiffs also had argued the
unconstitutionality of other provisions within the Act, the court found these other provisions
to be constitutionally sufficient. The court did, however, identify other problems with the
statute which the plaintiffs had not raised. Id. at 1462-67.
¶8 Having ruled the Act unconstitutional, the district court permanently enjoined the
defendants in that case—Neil Hartigan, in his official capacity as then-Attorney General of
Illinois, and Richard M. Daley, in his official capacity as then-State’s Attorney for Cook
County and as representative of all State’s Attorneys of all the counties of Illinois—from
enforcing the provisions of the Act.
¶9 The district court’s decision was affirmed in part and vacated in part by the Seventh
Circuit Court of Appeals. See Zbaraz v. Hartigan, 763 F.2d 1532 (7th Cir. 1985) (Zbaraz II).
The Seventh Circuit affirmed the district court’s holding that the requirement of a 24-hour
waiting period was unconstitutional, but found that portion of the Act to be severable. Id. at
1534. As to the “judicial bypass” procedures, however, the court vacated the district court’s
finding of unconstitutionality, but continued to enjoin enforcement of the statute “until the
Illinois Supreme Court promulgates rules which assure the expeditious and confidential
disposition of the waiver of notice proceedings at trial and on appeal.” Id. at 1535, 1540-41.
The court explained that, because time is of the essence in abortion decisions, the absence
of rules providing for an expedited appeal was a fundamental defect requiring the statute to
be enjoined. Id. at 1544 (relying on American College of Obstetricians & Gynecologists,
Pennsylvania Section v. Thornburgh, 737 F.2d 283, 297 (3d Cir. 1984)). The cause was
remanded to the district court “for a determination of the constitutionality of the waiver of
notice proceedings when such rules are enacted.” Id. at 1545.
¶ 10 The Seventh Circuit’s opinion was affirmed by the United States Supreme Court, without
opinion, “by an equally divided court.” Hartigan v. Zbaraz, 484 U.S. 171, 172 (1987) (per
curiam) (Zbaraz III).
¶ 11 Subsequently, then-Attorney General Neil Hartigan and then-State’s Attorney Cecil
Partee petitioned the federal district court to review the constitutionality of the 1983 Act in
light of Illinois Supreme Court Rule 307(e), which had been promulgated by this court to
provide for an expedited and confidential appeal of a waiver of notice decision. The district
court found, however, that the bypass procedure, as set forth in Rule 307(e), was insufficient
and did not cure the failure of the Parental Notice of Abortion Act of 1983 to provide a
constitutional alternative to parental notification. The district court held that the safeguards
for confidentiality and anonymity were insufficient to protect an unemancipated minor
seeking to have an abortion throughout the waiver process, that is, from the moment a waiver
petition is filed until the completion of any appeal. Accordingly, the court refused to lift the
permanent injunction. See Zbaraz v. Hartigan, 776 F. Supp. 375 (N.D. Ill. 1991) (Zbaraz

1
In striking down the judicial bypass procedures within the 1983 Act, the district court relied
heavily on the United States Supreme Court decision in Planned Parenthood Ass’n of Kansas City,
Missouri, Inc. v. Ashcroft, 462 U.S. 476 (1983), wherein the United States Supreme Court upheld
a statute which required minors to secure parental or judicial consent before obtaining an abortion.

 IV).
¶ 12 On June 1, 1995, the Illinois General Assembly repealed the 1983 Act and replaced it
with the Parental Notice of Abortion Act of 1995. See 750 ILCS 70/1 et seq. (West 1996).
The 1995 Act prohibits a physician from performing an abortion upon an unemancipated
minor or “incompetent person” unless “48 hours actual notice” is given to “an adult family
member.” 750 ILCS 70/15 (West 1996). The Act provides for certain exceptions to the notice
requirement when:
“(1) the minor or incompetent person is accompanied by a person entitled to
notice; or
(2) notice is waived in writing by a person who is entitled to notice; or
(3) the attending physician certifies in the patient’s medical record that a medical
emergency exists and there is insufficient time to provide the required notice; or
(4) the minor declares in writing that she is a victim of sexual abuse, neglect, or
physical abuse by an adult family member as defined in this Act. The attending
physician must certify in the patient’s medical record that he or she has received the
written declaration of abuse or neglect. Any notification of public authorities of abuse
that may be required under other laws of this State need not be made by the person
performing the abortion until after the minor receives an abortion that otherwise
complies with the requirements of this Act; or
(5) notice is waived under Section 25 [procedure for judicial waiver of notice].”
750 ILCS 70/20 (West 1996).
¶ 13 The 1995 Act, like the 1983 Act, requested the Illinois Supreme Court “to promulgate
any rules and regulations necessary to ensure that [judicial waiver] proceedings under this
Act are handled in an expeditious and confidential manner.” See 750 ILCS 70/25(g) (West
1996).
¶ 14 Six days later, on June 7, 1995, the plaintiffs amended their complaint in federal district
court to challenge the constitutionality of the 1995 Act. On June 9, 1995, an “Agreed
Preliminary Injunction” order was entered, which enjoined enforcement of the 1995 Act until
the Illinois Supreme Court had the opportunity to promulgate rules for implementing the
judicial bypass procedures, as requested in section 25(g) of the Act. See Zbaraz v. Madigan,
No. 84 C 771, 2008 U.S. Dist. LEXIS 15559 (N.D. Ill. Feb. 28, 2008).
¶ 15 On December 22, 1995, the defendants in this new suit (then-Attorney General Ryan and
then-Cook County State’s Attorney O’Malley) notified the federal district court that the
Illinois Supreme Court had declined to promulgate judicial bypass rules as requested by the
legislature. Accordingly, on February 9, 1996, a permanent injunction order was entered,
barring enforcement of the 1995 Act.
¶ 16 Ten years later, on September 20, 2006, this court adopted Illinois Supreme Court Rule
303A, entitled “Expedited and Confidential Proceedings Under the Parental Notification of
Abortion Act.” This rule provides: “Upon the filing of a petition in the circuit court for
judicial waiver of notice under the Parental Notification of Abortion Act, the circuit court
shall rule and issue written findings of fact and conclusions of law within 48 hours of the

-5-
 time that the petition is filed ***.” Ill. S. Ct. R. 303A(a) (eff. Sept. 20, 2006). The rule also
provides for confidentiality throughout the proceedings,2 the right to an expeditious appeal,
and the appointment of counsel upon the request of the minor. Ill. S. Ct. R. 303A(b), (d), (f)
(eff. Sept. 20, 2006).
¶ 17 Soon thereafter, Lisa Madigan, in her capacity as Attorney General of Illinois, and Anita
Alvarez, in her capacity as State’s Attorney of Cook County, filed a motion in the federal
district court seeking to have the February 9, 1996, permanent injunction order dissolved.
Plaintiffs objected, arguing that the new statute remained unconstitutional on its face.
¶ 18 On February 28, 2008, the federal district court denied the defendants’ motion, declining
to lift the injunction. See Zbaraz v. Madigan, 2008 U.S. Dist. LEXIS 15559. The court
rejected all of the plaintiffs’ allegations of unconstitutionality but one—the court found that
the statute effectively denied abortions to “immature, best interest” minors because they, due
to their immaturity, would be legally prohibited from consenting to an abortion and, thus,
were left in “legal limbo.”
¶ 19 The defendants filed an appeal from this decision in the Seventh Circuit Court of
Appeals. On the same day that the defendants’ appeal was filed, Stewart Umholtz, as State’s
Attorney of Tazewell County, and Edward Deters, as State’s Attorney of Effingham County,
filed a motion in the federal district court seeking to intervene in the case. They also asked
the district court to reconsider its earlier ruling that the 1995 Act was unconstitutional. Both
motions were denied and the proposed intervenors appealed to the Seventh Circuit. The
Seventh Circuit consolidated this appeal with the one brought by the defendants.
¶ 20 On review, the Seventh Circuit reversed the district court’s denial of the defendants’
motion to dissolve the permanent injunction barring enforcement of the statute. Zbaraz v.
Madigan, 572 F.3d 370 (7th Cir. 2009) (Zbaraz V). In its decision, filed on July 14, 2009,
the court of appeals held that the Act, as supplemented by the judicial bypass procedures for
obtaining a waiver of the parental notification requirement, was constitutional on its face.
With regard to the proposed intervenors’ appeal, the court affirmed the district court’s denial
of the motion to intervene, finding that the motion was untimely and, further, that the
interests of the proposed intervenors were adequately represented by the defendants. Id. at
377-78.
¶ 21 Three months later, on October 13, 2009, The Hope Clinic for Women and Dr. Allison
Cowett filed a complaint in the circuit court of Cook County against the Acting Secretary of

2
The rule provides in section (f): “The petitioner shall be identified in the petition and any
supporting memorandum in the method provided under Rule 660(c), as in appeals in cases arising
under the Juvenile Court Act. Alternatively, the petitioner may use a pseudonym if she so requests.
All documents relating to proceedings shall be impounded and sealed subject to review only by the
minor, her attorney and guardian ad litem, the respective judges and their staffs charged with
reviewing the case and the respective court clerks and their staffs.” Ill. S. Ct. R. 303A(f) (eff. Sept.
20, 2006).

 the Illinois Department of Financial and Professional Regulation (Manuel Flores3); the
Director of the Division of Professional Regulation of the Illinois Department of Financial
and Professional Regulation (Daniel Bluthardt); and the Illinois State Medical Disciplinary
Board. Plaintiffs sought a declaratory judgment, a temporary restraining order, and
preliminary and permanent injunctions against the enforcement of the Parental Notice of
Abortion Act of 1995. Plaintiffs alleged that the Act is facially invalid because it violates the
fundamental rights of minors who seek abortions to privacy (count I), due process (count II),
equal protection (count III), and gender equality (count IV), as guaranteed by the Illinois
Constitution of 1970 (Ill. Const. 1970, art. I, §§ 2, 6, 12, 18). Shortly after plaintiffs filed suit,
Stewart Umholtz, as State’s Attorney of Tazewell County, and Edward Deters, as State’s
Attorney of Effingham County, petitioned the circuit court for leave to intervene in the matter
as of right, or by permission.
¶ 22 On November 4, 2009, the circuit court entered a temporary restraining order enjoining
defendants from enforcing the Act. Thereafter, defendants, represented by Attorney General
Lisa Madigan, filed a motion for judgment on the pleadings or, in the alternative, dismissal
pursuant to sections 2-615(a) and (e), 2-619(a)(4), and 2-619.1 of the Code of Civil
Procedure (735 ILCS 5/2-615(a), (e), 2-619(a)(4), 2-619.1 (West 2008)).
¶ 23 On March 29, 2010, in a memorandum opinion and order, the circuit court granted
defendants’ motion and dismissed plaintiffs’ complaint with prejudice. The court held that
plaintiffs were collaterally estopped from litigating their due process and equal protection
claims by Zbaraz V because our state due process and equal protection clauses have been
interpreted in limited lockstep with the nearly identical due process and equal protection
clauses within the federal constitution. The circuit court also dismissed plaintiffs’ privacy
claim, finding that the burden which the Act places on a minor’s right to an abortion would
not be, in all circumstances, constitutionally unreasonable. Finally, the court dismissed
plaintiffs’ gender equality claim, finding that this provision of the Illinois Constitution is not
implicated by the Act. In light of its decision to dismiss plaintiffs’ complaint with prejudice,
the circuit court denied the proposed intervenors’ petition to intervene as moot.
¶ 24 Plaintiffs and the proposed intervenors appealed. The appellate court reversed the circuit
court’s dismissal of plaintiffs’ complaint and remanded for further proceedings. 2011 IL App
(1st) 101463. With respect to the proposed intervenors’ appeal, however, the appellate court
affirmed the circuit court’s decision to deny the petition to intervene. Id. ¶ 133.
¶ 25 We granted petitions for leave to appeal brought by defendants and the proposed
intervenors and consolidated them for our review. In addition, we allowed amicus curiae
briefs in support of defendants to be filed by: (1) the Christian Medical and Dental
Associations, the American Association of Pro Life Obstetricians and Gynecologists and the

¶ 27 ANALYSIS
¶ 28 In No. 112704, defendants, through their attorney, Lisa Madigan, Attorney General of
Illinois, appeal the appellate court’s reversal of the circuit court’s finding that the Parental
Notice of Abortion Act of 1995 is facially valid under the Illinois Constitution of 1970. In
No. 112673, Stewart Umholtz, as State’s Attorney of Tazewell County, and Edward Deters,
as State’s Attorney of Effingham County, appeal the appellate court’s judgment affirming
the circuit court’s denial of their petition to intervene. We will address defendants’ appeal
first.

¶ 29 I. No. 112704
¶ 30 A. Standard of Review
¶ 31 As noted above, plaintiffs’ complaint challenges the constitutionality of the Parental
Notice of Abortion Act of 1995, arguing that the Act is facially invalid under the due process,
equal protection, privacy, and gender equality clauses of our state constitution.4 Plaintiffs
contended that, under our state constitution, minors, like adults, have a fundamental right to
make reproductive decisions for themselves and that the Parental Notice of Abortion Act of
1995 places an unjustifiable burden on a minor’s exercise of that fundamental right by
preventing her from obtaining an abortion in Illinois unless a parent or guardian is first given
notice of the minor’s intention to have an abortion or the minor obtains a judicial waiver of
the notice requirement. The circuit court found the Act to be constitutionally valid on its face,
granted defendants’ motion for judgment on the pleadings and dismissed plaintiffs’
complaint with prejudice. The appellate court reversed the dismissal and remanded for trial.
¶ 32 What we consider in this appeal is the correctness of the circuit court’s grant of judgment
on the pleadings. Judgment on the pleadings is properly granted if the pleadings on file

4
We note that plaintiff’s challenge is necessarily a facial challenge because the Act, to date,
has never been enforced.

-8-
 disclose no genuine issues of material fact so that the movant is entitled to judgment as a
matter of law. Pekin Insurance Co. v. Wilson, 237 Ill. 2d 446, 455 (2010). Because the circuit
court ruled as a matter of law, our review of its judgment is de novo. Id.
¶ 33 We note, further, that when assessing the constitutional validity of a legislative act, we
must begin with the presumption of its constitutionality. Arangold Corp. v. Zehnder, 187 Ill.
2d 341, 351 (1999). The burden of rebutting this presumption is on the party challenging the
validity of the statute and any doubts must be resolved in favor of finding the law valid. In
re R.C., 195 Ill. 2d 291, 296 (2001); People v. Inghram, 118 Ill. 2d 140, 146 (1987). This
burden is particularly heavy where, as here, a facial challenge is raised. A facial challenge
to a legislative act is the most difficult challenge to mount successfully because the
challenger must establish that under no circumstances would the challenged act be valid.
Davis v. Brown, 221 Ill. 2d 435, 442 (2006). The fact that the statute might operate
unconstitutionally under some conceivable set of circumstances is insufficient to render it
wholly invalid. Id. As we said in Pooh-Bah Enterprises, Inc. v. County of Cook, 232 Ill. 2d
463, 473 (2009), “[f]acial invalidation is, manifestly, strong medicine that has been employed
by the court sparingly and only as a last resort.” (Internal quotation marks omitted.)

¶ 34 B. The Right to Abortion Under Our State Constitution
¶ 35 As a threshold matter, we observe that the parties to this appeal do not dispute that a right
to abortion exists under our state constitution. They disagree, however, on the origin and
scope of that right.
¶ 36 Plaintiffs, relying on Family Life League v. Department of Public Aid, 112 Ill. 2d 449
(1986), maintain that the fundamental right to make reproductive decisions for one’s self,
which was first recognized under the federal constitution in Roe v. Wade, 410 U.S. 113
(1973), is a privacy right and that this right is secured for Illinois citizens, including minors,
by our state constitution’s privacy clause. Plaintiffs further maintain that because our state
constitution contains an explicit right of privacy which the federal constitution does not have,
the right to an abortion under our state constitution is broader than the right to an abortion
under the federal constitution. For this reason, plaintiffs argue that the Illinois parental
notification statute is unconstitutional as a matter of state constitutional law, regardless of
what federal courts have said about such statutes as a matter of federal constitutional law.
¶ 37 Defendants, on the other hand, argue that plaintiffs’ reliance on Family Life League is
misplaced. According to defendants, “Faithful application of the constitutional language, the
records of the constitutional debates, and Illinois’ history and experience shows that it is
Illinois’ due process clause, not its [privacy clause contained within the] search and seizure
clause, that protects reproductive rights.” Subsequent to Roe, the United States Supreme
Court identified the federal right to abortion as a substantive due process right. See Planned
Parenthood of Southeastern Pennsylvania v. Casey, 505 U.S. 833 (1992). Defendants
contend that, because our due process clause is nearly identical to the due process clause in
the federal constitution, and because we interpret cognate provisions of our state and federal
constitutions in limited lockstep (see People v. Caballes, 221 Ill. 2d 282 (2006)), we should
follow the United States Supreme Court and find that a right to abortion derives from our due

-9-
 process clause. Additionally, defendants contend that there are no state grounds to depart
from lockstep and, thus, the right to abortion under our state constitution is coextensive with
the right to abortion under the federal constitution. Therefore, just as federal courts have
upheld parental notification statutes under the federal constitution, this court should uphold
the Illinois parental notification statute as a matter of state constitutional law.
¶ 38 Like defendants, we find plaintiffs’ reliance on Family Life League for the proposition
that a right to abortion in Illinois is guaranteed by our constitution’s privacy clause to be
problematic for a number of reasons. First and foremost, in Family Life League this court
was never asked to decide whether a right to abortion exists under our state constitution.
Family Life League was a mandamus action in which an anti-abortion group sought to force
the Department of Public Aid to disclose, pursuant to the State Records Act (Ill. Rev. Stat.
1979, ch. 116, ¶ 43.4 et seq.), the names of providers who had furnished abortion services
under the Illinois Medicaid program; the number of abortions they performed; and the
amounts they were paid for such services. Family Life League, 112 Ill. 2d at 451-52. Arguing
against disclosure, the Department contended that making the requested records available
could indirectly infringe on the recipient’s privacy rights. Id. at 454. The Department’s theory
was that divulging provider information might have an inhibiting effect on the number of
providers willing to participate in the Medicaid abortion program and, as a result, “violate
the holding in Roe v. Wade.” Id. at 454.
¶ 39 This court rejected the Department’s claim, but before doing so, made the following
statement: “In Roe v. Wade, the Supreme Court first recognized a fundamental constitutional
right of privacy which encompasses a woman’s decision of whether to terminate her
pregnancy. That right of privacy guaranteed by the penumbra of the Bill of Rights of the
United States Constitution was also secured by the drafters of the 1970 Constitution of the
State of Illinois. Ill. Const. 1970, art. I, secs. 6, 12.” Id. at 454.
¶ 40 It is not clear from the opinion what prompted the court to make the above statement.
However, we find it highly unlikely that the court intended, by this statement, not only to
decide the rather weighty question of whether our state constitution guarantees the right to
abortion, but also to conclude that such a right is guaranteed by our privacy clause, without
providing any analysis to support such findings. In any event, to the extent that Family Life
League might be interpreted as having made such findings, we find them to be dicta. As
noted above, the Department’s claims were based on the federal right to abortion and there
was no need for the court to determine whether a state constitutional right existed.
¶ 41 There are additional reasons why we reject plaintiffs’ contention that a right to abortion
in Illinois is guaranteed by our state constitution’s privacy clause. The privacy clause was
added to article I, section 6, of the Illinois Constitution of 1970. That section, which is often
referred to as the “search and seizure provision,” provides as follows:
“The people shall have the right to be secure in their persons, houses, papers and
other possessions against unreasonable searches, seizures, invasions of privacy or
interceptions of communications by eavesdropping devices or other means.”
(Emphasis added.) Ill. Const. 1970, art. I, § 6.
¶ 42 The privacy clause is unique to the Illinois Constitution, there being no cognate provision

-10-
 in the federal constitution. Accordingly, we interpret the provision without reference to a
federal counterpart. See Caballes, 221 Ill. 2d at 289. Also, in Caballes we noted that “the
protection against unreasonable invasions of privacy ‘is stated broadly,’ and ‘[n]o definition
of types of privacy’ intended to be protected ‘is offered.’ ” Id. at 317 (quoting ILCS Ann.,
Ill. Const. 1970, art. I, § 6, Constitutional Commentary, at 522 (Smith-Hurd 1993)). Thus,
in deciding the meaning of the privacy clause in our constitution, we look to the intent of the
drafters.
¶ 43 Having reviewed the committee reports and transcripts of the debates at the constitutional
convention, we find a variety of reasons were given for adding this privacy language. The
delegates, themselves, struggled to define with precision the parameters of the right which
they proposed to be added to article I, section 6. Mr. Gertz, chairman of the Bill of Rights
Committee, stated the following:
“We recognize in our report that in this kind of crowded, complicated world that
there are necessarily a lot of invasions of privacy—that some of those invasions are
reasonable. All we are saying, without spelling out in detail, is that a halt ought to be
called somewhere to these invasions of privacy. The individual ought not to be
completely at the mercy of the state. In every area we’re trying to have the individual
have a certain amount of dignity and have a certain amount of freedom from
governmental interference of any kind.” 3 Record of Proceedings, Sixth Illinois
Constitutional Convention 1535 (hereinafter Proceedings).
¶ 44 Another delegate, Mrs. MacDonald, indicated that the additional language was necessary
to address concerns that new, sophisticated technologies were being developed, or might be
developed in the future, which the government could use to invade a citizen’s privacy. 3
Proceedings 1534. Mr. Dvorak, who gave the opening presentation on article I, section 6,
discussed the two proposed additions to the search and seizure clause—“invasion of privacy”
and “interceptions of communications by eavesdropping devices.” With regard to the
invasion of privacy language, he said:
“But there is the area of privacy still existing in very particular instances. For
instance, we have now the concept of a general information bank whereby the state
government or the federal government can take certain pertinent information about
each and every one of us based on, for instance, our social security number—know
our weight, height, family ages, various things about us—and this is not acceptable
to—was not acceptable—or the theory or thought of such a thing—was not
acceptable to the majority of our committee in approving section 6.” 3 Proceedings
1525.
¶ 45 A comprehensive determination of all of the types of invasions of privacy the new clause
was intended to protect against need not be made here because, whatever its purpose, it is
clear that the privacy clause was not added to our constitution to address abortion rights. On
this point the intent of the drafters was explicitly stated. At the Constitutional Convention,
one of the delegates, Fr. Lawlor, posed a question to Mr. Gertz, chairman of the Bill of
Rights Committee:
“FATHER LAWLOR: Mr. Chairman—or rather Mr. Gertz—I would very much

-11-
 appreciate it if you would assure the entire delegation here that the right of the people
to be secure in their persons against unreasonable invasions of their privacy *** has
absolutely nothing to do with the question of abortion.
MR. GERTZ: It certainly has nothing to do with the question of abortion.” 3
Proceedings 1537.
¶ 46 In light of the above, we must conclude that any right to abortion in Illinois is clearly not
grounded in the privacy clause of our state constitution. Therefore, we now consider whether,
as defendants argue, a state constitutional right to abortion derives from our due process
clause.
¶ 47 The due process clause of our state constitution is found in article I, section 2 (Ill. Const.
1970, art. I, § 2), and the language of our due process clause is nearly identical to its federal
counterpart. As explained in Caballes, this court has adopted the “limited lockstep” approach
for interpreting cognate provisions of our state and federal constitutions. Under this
approach, when the language of the provisions within our state and federal constitutions is
nearly identical, departure from the United States Supreme Court’s construction of the
provision will generally be warranted only if we find “ ‘in the language of our constitution,
or in the debates and the committee reports of the constitutional convention, something
which will indicate that the provisions of our constitution are intended to be construed
differently than are similar provisions in the Federal Constitution, after which they are
patterned.’ ” Caballes, 221 Ill. 2d at 297 (quoting People v. Tisler, 103 Ill. 2d 226, 245
(1984)).
¶ 48 Applying the “limited lockstep” doctrine here, we first look to the United States Supreme
Court’s interpretation of the federal constitution’s due process clause. In Planned
Parenthood of Southeastern Pennsylvania v. Casey, 505 U.S. 833, 846 (1992), the Court
held:
“Constitutional protection of the woman’s decision to terminate her pregnancy
derives from the Due Process Clause of the Fourteenth Amendment. It declares that
no State shall ‘deprive any person of life, liberty, or property, without due process of
law.’ The controlling word in the cases before us is ‘liberty.’ Although a literal
reading of the Clause might suggest that it governs only the procedures by which a
State may deprive persons of liberty, for at least 105 years, since Mugler v. Kansas,
123 U.S. 623, 660-661 (1887), the Clause has been understood to contain a
substantive component as well, one ‘barring certain government actions regardless
of the fairness of the procedures used to implement them.’ Daniels v. Williams, 474
U.S. 327, 331 (1986).”
¶ 49 The Casey Court went on to explain:
“The most familiar of the substantive liberties protected by the Fourteenth
Amendment are those recognized by the Bill of Rights. We have held that the Due
Process Clause of the Fourteenth Amendment incorporates most of the Bill of Rights
against the States. See, e.g., Duncan v. Louisiana, 391 U.S. 145, 147-148 (1968). It
is tempting, as a means of curbing the discretion of federal judges, to suppose that
liberty encompasses no more than those rights already guaranteed to the individual

-12-
 against federal interference by the express provisions of the first eight Amendments
to the Constitution. See Adamson v. California, 332 U.S. 46, 68-92 (1947) (Black,
J., dissenting). But of course this Court has never accepted that view.
It is also tempting, for the same reason, to suppose that the Due Process Clause
protects only those practices, defined at the most specific level, that were protected
against government interference by other rules of law when the Fourteenth
Amendment was ratified. See Michael H. v. Gerald D., 491 U.S. 110, 127-128, n.6
(1989) (opinion of SCALIA, J.). But such a view would be inconsistent with our law.
It is a promise of the Constitution that there is a realm of personal liberty which the
government may not enter. We have vindicated this principle before. Marriage is
mentioned nowhere in the Bill of Rights and interracial marriage was illegal in most
States in the 19th century, but the Court was no doubt correct in finding it to be an
aspect of liberty protected against state interference by the substantive component of
the Due Process Clause in Loving v. Virginia, 388 U.S. 1, 12 (1967) (relying, in an
opinion for eight Justices, on the Due Process Clause).” Casey, 505 U.S. at 847-48.
¶ 50 Given our adherence to “limited lockstep,” we should interpret the due process clause of
our state constitution the same way that the United State Supreme Court has interpreted the
due process clause in the federal constitution unless there is something in the language of our
constitution, or in the debates and the committee reports of the constitutional convention,
which would indicate that the due process provision within our state constitution was
intended to be construed differently.
¶ 51 Turning to that inquiry, we find that, at the Sixth Illinois Constitutional Convention, there
was a great deal of discussion about the language of our state’s due process clause. This
discussion centered around a “majority” proposal to modify the clause by adding the words
“including the unborn” so that our state due process clause would read, “No person,
including the unborn, shall be deprived of life, liberty or property ***.” (Emphasis added.)
3 Proceedings 1498-1523. From a reading of the debates, it is clear that the delegates were
fully aware that this change in language would mean a deviation from the language of the
federal due process clause. Mr. Wilson, a representative of the “minority” position, which
opposed the addition of these three words, explained:
“Mr. President and fellow delegates, we are considering today a due process clause
different than any other due process clause. It has no counterpart in the due process
clause of any other state, and it is different than the due process clause in our Federal
Constitution. Three words have been added to the due process clause which we are
talking about. Those three words are ‘including the unborn.’ *** They are put in
there by design—by intention—and there is a purpose and meaning to them. And I
think, before we can intelligently decide the question before us, we have to know
what these three words mean.” 3 Proceedings 1504.
¶ 52 Mr. Wilson continued to elaborate on what he believed the purpose of the additional
words to be:
“Now the three key words in the due process clause are ‘life,’ ‘liberty,’ and
‘property.’ ***

-13-
 ***
*** And obviously it is the intention of the new clause to refer to life. This, the
minority believes, is plain and obviously an attempt to strengthen the due process
clause which now protects all persons so as to make it perfectly clear under the due
process clause that any liberalization of abortion—any liberal abortion law—would
run into this further obstacle in the due process clause of the three words, ‘including
the unborn.’
***
Now, as Chairman Gertz said, we did have before us, prior to the time that this
proposal was acted on, a proposal that spoke directly to the matter of abortion,[5] and
it was defeated, although—as I recall—several committee members were absent at
the time of that vote. I want to make clear the position of the minority. It is the
position of the minority that the legislature should be left free to deal with the
question of abortion under the due process clause as it now stands, and that no
further impediments on the power of the legislature to act freely should be inserted
in the due process clause in the form of these words. It is not the position of the
minority that the constitution should speak to the question of abortion by putting into
the constitution some provision that presumably would authorize or make more
constitutional, if you please, the enactment of what I will refer to as liberalized
abortion laws. It is our position that the constitution should not address itself to the
question of abortion at all, but that this should be left to be acted upon by the
legislature under the existing language of the due process clause.” (Emphases
added.) 3 Proceedings 1504.
¶ 53 Shortly thereafter, Mr. Wilson turned the floor over to Mr. Weisberg for further
presentation on the subject. Mr. Weisberg continued to explain the minority position, stating:
“The minority has made the point that since there are deep religious differences in
our society on this issue that we feel that views of any particular religious group or
groups should not be written into the constitution on this subject. ***
***
*** There are serious problems here. It has been pointed out more and more
frequently in recent years that there are serious medical and social problems which
the Constitutional Convention, we submit, is not equipped to study and evaluate.
*** It seems clear that some legislatures which have moved to modify their law
in this field have been responding to the judgment that enormous human suffering
results from their laws in their present form.

5
Certain delegates had previously suggested that the right to abortion be expressly protected
by adding to the Bill of Rights the following language: “No penalty may be imposed by law upon
any person in connection with an abortion performed by a licensed physician with the consent of the
woman upon whom it is performed and, if she is an unmarried minor, the consent of her parents or
guardian.”

-14-
 It has been observed—and I think we’ll hear more about this in the debate—that
the effect of the laws has not been really to eliminate the termination of pregnancies,
but has been to drive them underground at enormous economic, social, and human
cost ***. The discrimination against the poor and the deprived of our society that
results is—has been amply documented.” 3 Proceedings 1505.
¶ 54 Finally, in his closing remarks, Mr. Weisberg quoted the minority report’s final
paragraph:
“ ‘There are deep religious differences in our society on this issue. It would be
wrong to write into the constitution the view of any religious group on the subject of
abortion. In this area the law, especially the constitution, should be neutral and
should protect the rights of all persons to act in accordance with their own religious
and moral convictions.’ ” (Emphasis added.) 3 Proceedings 1506.
¶ 55 After considerable discussion, the majority proposal—to add the words “including the
unborn”—failed. The minority position was adopted, overwhelmingly, by a vote of 80-32.
Therefore, the end result of the debates at the Constitutional Convention was that our due
process clause remained unchanged. That being so, there is nothing in those debates or
committee reports which demonstrate “ ‘that the provisions of our constitution are intended
to be construed differently than are similar provisions in the Federal Constitution, after which
they are patterned.’ ” See Caballes, 221 Ill. 2d at 297 (quoting People v. Tisler, 103 Ill. 2d
226, 245 (1984)). Accordingly, we find no state grounds for deviating from the United States
Supreme Court’s interpretation that the federal due process clause protects a woman’s right
to an abortion. Therefore, at this time, we interpret our state due process clause to provide
protections, with respect to abortion, equivalent to those provided by the federal due process
clause.

¶ 56 C. The Parental Notice of Abortion Act of 1995
¶ 57 We must now determine whether the Parental Notice of Abortion Act of 1995 violates
a woman’s substantive due process right to an abortion. As noted above, plaintiffs contend
that the Act violates the privacy, due process, equal protection, and gender equality clauses
of our state constitution.

¶ 58 1. Count I: Right to Privacy
¶ 59 Plaintiffs alleged in count I of their complaint that the Parental Notice of Abortion Act
of 1995 violates the privacy clause found in our state constitution in article I, section 6 (Ill.
Const. 1970, art. I, § 6), by unreasonably intruding upon a minor woman’s right to bodily
autonomy and her right to make medical decisions about her reproductive health care. These
assertions are based upon the premise that a woman’s right to an abortion is protected by our
constitution’s privacy clause, and that our state constitution provides greater privacy
protection than the federal constitution because our state constitution has an express privacy
clause, which the federal constitution does not have. Plaintiffs also contended that the Act
violates the privacy clause by interfering with a minor’s right to keep her medical
information confidential. Pointing out that, in Kunkel v. Walton, 179 Ill. 2d 519, 537-38

-15-
 (1997), we said “confidentiality of personal medical information is, without question, at the
core of what society regards as a fundamental component of individual privacy,” plaintiffs
argued that the Act unreasonably requires a pregnant minor to reveal information regarding
some of the most intimate aspects of her life before she may exercise her right to have an
abortion.
¶ 60 Although the circuit court accepted plaintiffs’ premise that our constitution’s privacy
clause protects the right to an abortion, the court rejected plaintiffs’ claim that the Act, on
its face, violates the privacy clause of our state constitution. The court held that, since our
constitution precludes only those invasions of privacy which are unreasonable, the Act does
not violate the privacy clause because the disclosure of information necessary to obtain an
abortion pursuant to the Act would not, in all instances, be unreasonable.
¶ 61 The appellate court reversed the circuit court. First, the appellate court noted that
plaintiffs’ privacy claim implicates two aspects of the Illinois privacy clause: the right to an
abortion and the right against state-ordered disclosure of medical information. As to the right
to an abortion, the appellate court agreed with the circuit court that, pursuant to Family Life
League, our privacy clause protects the right to an abortion. However, the court rejected the
circuit court’s subsequent finding that the right to an abortion under our privacy clause is
coextensive with the federal right. The appellate court also held that, pursuant to People v.
Caballes, 221 Ill. 2d 282 (2006), our privacy clause must be interpreted separately and
without reference to the federal constitution because it has no federal counterpart and, for
that reason, remanded for further proceedings. 2011 IL App (1st) 101463, ¶ 96. In addition,
the appellate court rejected the circuit court’s alternative basis for dismissal—its
reasonableness determination—finding it to be “unsupported.” 2011 IL App (1st) 101463,
¶¶ 107-12.
¶ 62 As discussed earlier in this decision, we reject plaintiffs’ premise that our constitution’s
privacy clause protects a woman’s right to have an abortion. However, we agree with the
appellate court that the other aspect of the privacy clause—the guarantee against state-
ordered disclosure of medical information—is implicated by plaintiffs’ privacy claim. In
addition, we agree that our state constitution, by expressly guaranteeing a right of privacy,
provides protections which are separate and distinct from those provided under the federal
constitution. As we said in In re May 1991 Will County Grand Jury, 152 Ill. 2d 381, 391
(1992), “the Illinois Constitution goes beyond Federal constitutional guarantees by expressly
recognizing a zone of personal privacy.” However, we see no need to remand this matter to
the circuit court. The issue here—whether the Parental Notice Act violates our constitution’s
privacy clause—is a legal question and, therefore, suitable for decision by this court.
¶ 63 The privacy clause of the Illinois Constitution forbids unreasonable invasions of privacy.
Ill. Const. 1970, art. I, § 6; Kunkel, 179 Ill. 2d at 538. It is undoubtedly true, as plaintiffs
contend, that the Act, by requiring minors who seek an abortion to give notice to an adult
family member or obtain a judicial waiver of such notice, interferes with the minor’s right
to keep medical information confidential. However, we find, as did the circuit court below,
that plaintiffs cannot show that the Act’s intrusions on a minor’s privacy are
unreasonable—at least not in all cases, which is all that is necessary to defeat a facial
challenge.

-16-
¶ 64 It was observed in In re J.T., 221 Ill. 2d 338 (2006), that “[j]uveniles are a vulnerable
population” and “ ‘[o]ur history is replete with laws and judicial recognition that minors,
especially in their earlier years, generally are less mature and responsible than adults.
Particularly “during the formative years of childhood and adolescence, minors often lack the
experience, perspective, and judgment” expected of adults.’ ” In re J.T., 221 Ill. 2d at 380
(Freeman, J., dissenting) (quoting Eddings v. Oklahoma, 455 U.S. 104, 115-16 (1982)).
Thus, while a notice requirement similar to the one in the Act has been held unconstitutional
when imposed on an adult (see Casey, 505 U.S. 833 (spousal notification statute
unconstitutional under substantive due process)), it does not necessarily follow that it is
unconstitutional to impose a notification requirement on minors, who, studies have shown,
often lack the maturity and experience to make important decisions on their own. See Roper
v. Simmons, 543 U.S. 551, 569 (2005) (noting that scientific and sociological studies tend
to confirm a lack of maturity and an underdeveloped sense of responsibility are found in
youth more often than in adults). Reasonableness is the touchstone of the privacy clause and
we cannot say that treating minors differently than adults is unreasonable.
¶ 65 In Kunkel v. Walton, we recognized for the first time that our state constitutional privacy
guarantee protects a person’s reasonable expectation of privacy in his or her personal medical
information. See Kunkel, 179 Ill. 2d at 537-38. However, we also recognized that “[t]he text
of our constitution does not accord absolute protection against invasions of privacy. Rather,
it is unreasonable invasions of privacy that are forbidden.” (Emphasis omitted.) Id. at 538.
We then held in Kunkel that section 2-1003(a) of the Code of Civil Procedure (735 ILCS 5/2-
1003(a) (West 1994)), which required any party to a lawsuit who alleged a claim for bodily
injury or disease to waive any privilege of confidentiality with his or her health care
providers, violated our state constitution’s privacy clause. We found the statute to be
unreasonable because the waiver requirement was overly broad, requiring full disclosure of
medical information that was not relevant to the issues in the lawsuit.
¶ 66 Similarly, in In re Lakisha M., 227 Ill. 2d 259, 279 (2008), we held that where a privacy
right under article I, section 6, is implicated, the critical question is whether the state’s
invasion of individual privacy is reasonable. Further, we held that “[r]easonableness, with
regard to our state constitution’s privacy clause, depends, largely, on the extent of one’s
expectation of privacy under the circumstances presented, as well as the degree of
intrusiveness of the invasion of privacy.” See also People v. Caballes, 221 Ill. 2d 282, 321,
327 (2006) (citing People v. Cornelius, 213 Ill. 2d 178, 193-94 (2004) (claims alleging a
violation of our state privacy clause require a twofold inquiry: first, whether the party has a
reasonable expectation of privacy in the information he seeks to protect and, second, whether
the statute unreasonably invades that expectation of privacy)). In Lakisha M., we determined
that the extraction of DNA fell within the “zone of privacy” protected by our constitution’s
privacy clause. Lakisha M., 227 Ill. 2d at 280. Nevertheless, we found the invasion of privacy
to be minimal and upheld the constitutionality of the DNA indexing statute (730 ILCS 5/5-4-
3 (West 2008)).
¶ 67 Applying the above standards here, we find that, while a minor clearly has an expectation
of privacy in her medical information, which includes the fact of her pregnancy, the intrusion
on the minor’s privacy occasioned by the Act is not unreasonable. The state has an interest

-17-
 in ensuring that a minor is sufficiently mature and well-informed to make the difficult
decision whether to have an abortion. To advance that interest, it is reasonable for the state
to encourage an unemancipated minor under the age of 18 who wishes to have an abortion
to seek the support of a parent or other interested adult, or to require her to prove her
maturity by obtaining a judicial waiver in a waiver process that is expedited and confidential.
See 750 ILCS 70/25 (West 2010).6 The Act is not unduly burdensome since it requires the
minor to give notice to only one legally responsible adult (see 750 ILCS 70/10 (West 2010))
and provides for an exception to the notice requirement when a medical emergency exists
and there is insufficient time to provide the required notice (see 750 ILCS 70/20 (West
2010)).
¶ 68 In light of the above, we agree with defendants that the Act is crafted narrowly to achieve
its aim of promoting the minors’ best interests through parental consultation. Accordingly,
we find the Act is reasonable and, therefore, does not violate our state constitutional
guarantee of privacy.
¶ 69 We reverse the judgment of the appellate court on count I and affirm the judgment of the
circuit court.

¶ 70 2. Counts II and III: Due Process and Equal Protection
¶ 71 Plaintiffs alleged in count II that the Act violates substantive components of the Illinois
Constitution’s due process clause by unjustifiably impairing a minor woman’s fundamental
right to obtain an abortion. It does so, according to plaintiffs, “by unlawfully intruding upon
a young woman’s rights to bodily autonomy, to make decisions about her reproductive
healthcare, and to keep medical information confidential.” In count III, plaintiffs alleged that
the Act violates equal protection “by discriminating against minors on the basis of their
decision to exercise their fundamental right to abortion.” Plaintiffs contended that there is
no justification for requiring minors who choose abortion to notify a responsible adult, while
placing no such requirement on minors who choose childbirth.
¶ 72 Our state constitution guarantees its citizens equal protection and due process of law in
article I, section 2, which provides:
“No person shall be deprived of life, liberty or property without due process of
law nor be denied the equal protection of the laws.” Ill. Const. 1970, art. I, § 2.
¶ 73 Our due process and equal protection clauses are nearly identical to their federal
counterparts, found in the fourteenth amendment of the United States Constitution:
“[N]or shall any State deprive any person of life, liberty, or property, without due

6
Section 25 of the Act provides:
“Court proceedings under this Section shall be confidential and shall ensure the
anonymity of the minor or incompetent person. All court proceedings under this
Section shall be sealed. The minor or incompetent person shall have the right to file
her petition in the circuit court using a pseudonym or using solely her initials. All
documents related to this petition shall be confidential and shall not be made
available to the public.”

-18-
 process of law; nor deny to any person within its jurisdiction the equal protection of
the laws.” U.S. Const., amend. XIV, § 1.

¶ 74 a. Limited Lockstep and Collateral Estoppel
¶ 75 In the circuit court, defendants initially countered plaintiffs’ due process and equal
protection claims by arguing that, because Illinois analyzes cognate provisions of our state
and federal constitutions in “limited lockstep,” plaintiffs’ equal protection and due process
claims were settled by the Zbaraz V decision and, thus, plaintiffs are collaterally estopped
from relitigating those claims in state court. The circuit court adopted this reasoning and,
without considering the merits of plaintiffs’ due process and equal protection claims, held
that it was constrained to find the Act constitutionally valid under the due process and equal
protection clauses of our state constitution because “plaintiffs’ equal protection and due
process issues were sufficiently and finally decided by the federal litigation.” The appellate
court reversed, offering a number of reasons why it was error for the circuit court to have
relied upon collateral estoppel to dismiss plaintiffs’ due process and equal protection claims.
2011 IL App (1st) 101463, ¶¶ 68-79.
¶ 76 Before this court, defendants argue that the appellate court erred in reinstating plaintiffs’
due process and equal protection claims. They contend that the appellate court “misapplied
established collateral estoppel doctrine” and continue to maintain that collateral estoppel
applies here to preclude plaintiffs’ due process and equal protection claims. We disagree.
¶ 77 As the parties acknowledge, for collateral estoppel to apply: (l) the issue decided in the
prior proceeding must be identical to the one in the current suit; (2) the prior adjudication
must have been a final judgment on the merits; and (3) the party against whom the estoppel
is asserted must have been a party to, or must be in privity with a party to, the prior
adjudication. In re A.W., 231 Ill. 2d 92, 99 (2008). Here there can be no collateral estoppel
because the issues decided in the prior federal proceedings (Zbaraz V) are not identical to the
issues presented in the current state suit. In Zbaraz V, the Seventh Circuit Court of Appeals
considered whether the Illinois Parental Notice of Abortion Act violated the due process and
equal protection clauses of the United States Constitution. In this suit, however, plaintiffs’
complaint alleges that the Act violates the due process and equal protection clauses of our
state constitution. While it is true that this court has typically construed our state due process
and equal protection clauses as providing the same level of protection as provided by the
nearly identical clauses within the federal constitution, we are not required to do so. See
People v. Caballes, 221 Ill. 2d 282, 314 (2006) (“Th[e] limited lockstep approach is not a
surrender of state sovereignty or an abandonment of the judicial function. *** [S]tate courts
are free to independently construe their state constitutions to provide more protection than
the federal constitution.”); People v. McCauley, 163 Ill. 2d 414, 436 (1994) (“in the context
of deciding State guarantees, Federal authorities are not precedentially controlling; they
merely guide the interpretation of State law”).
¶ 78 Moreover, Zbaraz V is a Seventh Circuit Court of Appeals decision and this court has
consistently recognized that federal lower court decisions interpreting federal constitutional
provisions—like the Zbaraz V decision here—are merely persuasive authority and are not

-19-
 binding on our state courts. People v. Kokoraleis, 132 Ill. 2d 235, 293-94 (1989) (“Because
lower Federal courts exercise no appellate jurisdiction over State courts, decisions of lower
Federal courts are not conclusive on State courts ***.”); People v. Stansberry, 47 Ill. 2d 541,
544-45 (1971).
¶ 79 Illinois courts, not federal courts, are the arbiters of state law. No federal court can
interpret the meaning of our state constitutional provisions. The Illinois Constitution’s
guarantees of due process and equal protection (Ill. Const. 1970, art. I, § 2) stand separate
and independent from the federal guarantees of those rights. People v. McCauley, 163 Ill. 2d
414 (1994); People ex rel. Daley v. Joyce, 126 Ill. 2d 209 (1988). Indeed, at various times
this court has conducted an independent analysis of the Illinois Constitution and found that
certain provisions offer our citizens greater protections than those enjoyed under the United
States Constitution. People v. Caballes, 221 Ill. 2d 282 (2006); People v. McCauley, 163 Ill.
2d 414 (1994); People v. DiGuida, 152 Ill. 2d 104 (1992). While this court may, in
construing the Illinois Constitution’s guarantees of due process and equal protection, look
for guidance and inspiration to constructions of their federal counterparts given by federal
courts, the final decision on how the due process and equal protection guarantees of the
Illinois Constitution should be construed is for this court to draw. Rollins v. Ellwood, 141 Ill.
2d 244, 275 (1990). Accordingly, we find that the circuit court erred in dismissing plaintiffs’
due process and equal protection claims based on collateral estoppel.

¶ 80 b. Merits
¶ 81 Having determined that collateral estoppel does not apply, we address defendants’
alternative argument, i.e., that plaintiffs’ due process and equal protection claims fail on their
merits. Under substantive due process principles, a statute will be held unconstitutional if it
impermissibly restricts a person’s life, liberty or property interest. People v. R.G., 131 Ill. 2d
328, 342 (1989). If the life, liberty or property interest is a fundamental right, then a statute
limiting that right “ ‘may be justified only by a “compelling state interest,” [citations] and
*** must be narrowly drawn to express only the legitimate state interests at stake.’ ” Id. at
342 (quoting Roe v. Wade, 410 U.S. 113, 155 (1973)). Equal protection guarantees that
similarly situated individuals will be treated similarly, unless the government demonstrates
an appropriate reason to do otherwise. City of Urbana v. Andrew N.B., 211 Ill. 2d 456, 466
(2004); F.S. Royster Guano Co. v. Virginia, 253 U.S. 412, 415 (1920). Equal protection
prohibits the state from according unequal treatment to persons placed by a statute into
different classes for reasons wholly unrelated to the purpose of the legislation. People v. R.L.,
158 Ill. 2d 432, 437 (1994); People v. R.G., 131 Ill. 2d at 362. The standard for reviewing
an equal protection claim is identical to that used for substantive due process, i.e., if the
statute infringes upon a fundamental right, then the statute must withstand strict scrutiny and
will only survive if it is necessary to promote a compelling state interest and narrowly
tailored to effectuate that state interest. Id. See also In re D.W., 214 Ill. 2d 289 (2005);
People v. Cornelius, 213 Ill. 2d 178, 204 (2004) (where the right alleged to be infringed is
a fundamental constitutional right, the challenged statute, to comport with substantive due
process and equal protection, must survive strict scrutiny analysis, that is, the means
employed by the legislature must be necessary to achieve a compelling state interest, and the

-20-
 statute must be narrowly tailored to accomplish this goal).
¶ 82 Plaintiffs argued in their complaint that the Act violates substantive due process and
equal protection because it “unjustifiably places a restriction on a pregnant minor’s
fundamental right to have an abortion” and “singles out pregnant minors who choose
abortion and imposes on them alone a requirement of parental notification as a condition of
receiving medical care.”
¶ 83 Once again relying on principles of lockstep, defendants contend that, because the due
process and equal protection clauses of our state constitution are nearly identical to the due
process and equal protection clauses of our federal constitution, our “limited lockstep”
approach to interpreting cognate provisions of our state and federal constitutions requires us
to interpret our state due process and equal protection clauses in a manner consistent with
the United States Supreme Court’s interpretation of the federal provisions unless there is
some reason, such as the language of our constitution, the constitutional convention debates
and committee reports, or state custom and practice, which indicate that the provisions of our
constitution are intended to be construed differently. Caballes, 221 Ill. 2d at 310. In addition,
defendants contend that there are no state grounds which would support a departure from
federal precedent and, therefore, we should uphold the constitutionality of the Act based on
the reasoning of the United States Supreme Court, which the Zbaraz V court relied upon
when it upheld our Illinois parental notification statute against challenges brought pursuant
to the due process and equal protection clauses of the federal constitution.
¶ 84 Plaintiffs agree that where, as here, cognate provisions of our state and federal
constitutions are concerned, Illinois courts will generally follow federal precedent absent a
reason to depart from federal law. However, plaintiffs contend that there is “ample reason”
to depart from federal precedent here because “defendants simply cannot meet their burden
of justifying interference with the fundamental right to abortion under [strict] scrutiny
without an evidentiary hearing.” Plaintiffs argue that we should affirm the appellate court’s
remand of this matter for trial and not simply rely on federal precedent because the federal
cases “do not address many of the most problematic aspects of the Act, nor do they consider
the scientific evidence that Plaintiffs have pled.”
¶ 85 We disagree with plaintiffs and find remand unnecessary. Over the last four decades, the
United States Supreme Court, as well as numerous other state and federal courts, have
addressed challenges to the constitutionality of parental consent and parental notification
statutes. During this time, all of the “problematic aspects” of parental notification statutes
which plaintiffs raise before this court have been considered and rejected.
¶ 86 While it is unquestionably true that minors, like adults, possess constitutional rights,
including the right to an abortion, the rights of minors are not coextensive with the rights of
an adult. See Planned Parenthood of Central Missouri v. Danforth, 428 U.S. 52 (1976).
Indeed, the very fact that we have a juvenile justice system is an acknowledgment that minors
may constitutionally be treated differently than adults. See Bellotti v. Baird, 443 U.S. 622,
635 (1979) (plurality op.) (Bellotti II). This disparate treatment is “grounded in the
recognition that, during the formative years of childhood and adolescence, minors often lack
the experience, perspective, and judgment to recognize and avoid choices that could be

-21-
 detrimental to them.” Id. In addition, when considering the constitutionality of a parental
notification statute, the minor’s rights are not the only rights to be protected—parents have
a constitutional right to raise their children and “the guiding role of parents in the upbringing
of their children justifies limitations on the freedoms of minors.” Id. at 637. In light of these
competing interests, the United States Supreme Court has concluded that states may require
a pregnant minor to notify her parents before obtaining an abortion as long as the state also
provides an alternative procedure whereby authorization for the abortion can be obtained. Id.
at 643.
¶ 87 The “alternative procedure” which saves a parental notification statute must meet four
criteria. It must: “(i) allow the minor to bypass the consent [notice] requirement if she
establishes that she is mature enough and well enough informed to make the abortion
decision independently; (ii) allow the minor to bypass the consent [notice] requirement if she
establishes that the abortion would be in her best interests; (iii) ensure the minor’s
anonymity; and (iv) provide for expeditious bypass procedures.” See Lambert v. Wicklund,
520 U.S. 292, 295 (1997). A parental notification statute having a bypass procedure which
satisfies these criteria does not unconstitutionally burden a minor’s right to an abortion under
the federal constitution. Id.
¶ 88 Challenges to the constitutionality of parental notification statutes brought on federal
substantive due process grounds have been rejected based on the Supreme Court’s finding
that parental notification serves compelling state interests and, when containing a proper
judicial bypass procedure, the statutes are narrowly tailored to serve those interests. See Ohio
v. Akron Center for Reproductive Health, 497 U.S. 502 (1990) (holding that Ohio parental
notice statute does not violate the fourteenth amendment); H.L. v. Matheson, 450 U.S. 398
(1981) (state notification statute plainly serves important state interests, is narrowly drawn
to protect only those interests, and does not violate any guarantees of the Constitution, even
though the statute allows a pregnant minor to consent to other medical procedures without
formal notice to her parents if she carries the child to term); Bellotti II, 443 U.S. 622
(parental notice and consent are qualifications that typically may be imposed by the state on
a minor’s right to make important decisions because a state reasonably may determine that
parental consultation often is desirable and in the best interest of the minor).
¶ 89 In Hodgson v. Minnesota, 497 U.S. 417 (1990), the Supreme Court invalidated a two-
parent notification requirement in Minnesota’s parental notification of abortion statute, but
otherwise found the act to be constitutional. In so doing, the Court held:
“The State has a strong and legitimate interest in the welfare of its young citizens,
whose immaturity, inexperience, and lack of judgment may sometimes impair their
ability to exercise their rights wisely. See Bellotti II, 443 U.S., at 634-639 (opinion
of Powell, J.); Prince v. Massachusetts, 321 U.S. 158, 166-167 (1944). That interest,
which justifies state-imposed requirements that a minor obtain his or her parent’s
consent before undergoing an operation, marrying, or entering military service,
[citations], extends also to the minor’s decision to terminate her pregnancy. Although
the Court has held that parents may not exercise ‘an absolute, and possibly arbitrary,
veto’ over that decision, [citation], it has never challenged a State’s reasonable
judgment that the decision should be made after notification to and consultation with

-22-
 a parent. See Ohio v. Akron Center for Reproductive Health, [497 U.S.] at 510-511;
Akron v. Akron Center for Reproductive Health, Inc., 462 U.S. 416, 428, n.10, 439
(1983); H.L. v. Matheson, 450 U.S., at 409-410; Bellotti II, 443 U.S., at 640-641
(opinion of Powell, J.); Danforth, 428 U.S., at 75. As Justice Stewart, joined by
Justice Powell, pointed out in his concurrence in Danforth:
‘There can be little doubt that the State furthers a constitutionally permissible
end by encouraging an unmarried pregnant minor to seek the help and advice of
her parents in making the very important decision whether or not to bear a child.’
Id., at 91.” Hodgson, 497 U.S. at 444-45.
¶ 90 The United States Supreme Court also has rejected claims, similar to those raised by
plaintiffs here, that requiring parental notice for abortions, but not other types of medical
care, violates equal protection. In Bellotti II, the Court explained that the abortion decision
differs in important ways from other decisions that may be made during minority because the
abortion decision has implications far broader than those associated with most other kinds
of medical treatment. Bellotti II, 443 U.S. at 642, 649. Thus, the Court concluded that “a
State reasonably may determine that parental consultation [regarding abortion] often is
desirable and in the best interest of the minor” and, accordingly, may validly limit the
freedom of children to choose for themselves in the making of such an important, affirmative
choice with potentially serious consequences. See Bellotti II, 443 U.S. at 640, 648-49;
Matheson, 450 U.S. at 412-13 (“If the pregnant girl elects to carry her child to term, the
medical decisions to be made entail few—perhaps none—of the potentially grave emotional
and psychological consequences of the decision to abort.”).
¶ 91 We are persuaded by the reasoning contained in the Supreme Court cases which have
found parental notification statutes constitutional under federal substantive due process and
equal protection law. We conclude, therefore, that our Parental Notice Act furthers a
“constitutionally permissible end” by encouraging an unmarried, pregnant minor to seek the
help and advice of a parent or other adult family member in making the very important
decision whether or not to bear a child. See Danforth, 428 U.S. at 91. Moreover, we agree
that the decision to undergo the surgical procedure of an abortion is sufficiently
distinguishable from other medical care decisions and, thus, provides a basis for treating
pregnant minors who choose abortion differently than those who choose to continue their
pregnancy. As noted above, equal protection requires that “all persons similarly
circumstanced *** be treated alike.” F.S. Royster Guano Co. v. Virginia, 253 U.S. 412, 415
(1920). It does not, however, “require things which are different in fact or opinion to be
treated in law as though they were the same.” (Internal quotation marks omitted.) Plyler v.
Doe, 457 U.S. 202, 216 (1982).
¶ 92 Finally, we find no state grounds for disregarding federal precedent when interpreting our
state constitution’s due process and equal protection clauses. Since both our state constitution
and the federal constitution use similar language in setting forth the due process and equal
protection guarantees, a departure from the United States Supreme Court’s interpretation of
the federal clauses is warranted only if there is good cause for doing so. In other words, we
must be able to point to something in the constitutional debates and records, or our state
history or custom, which would suggest that a different meaning should attach to our due

-23-
 process and equal protection clauses.
¶ 93 Plaintiffs have offered no state-based rationale for interpreting our clauses differently
than the United States Supreme Court interprets the federal clauses. Instead, plaintiffs simply
seek to have us affirm the appellate court’s remand to afford plaintiffs the opportunity to
show that the Supreme Court decisions relied upon by defendants are premised on “outdated
assumptions and prejudices about abortion.”
¶ 94 We are unpersuaded by plaintiffs’ arguments. Finding no reason to depart from lockstep
here, we adopt the reasoning of the United States Supreme Court in holding that the Illinois
Parental Notice of Abortion Act of 1995 does not violate our state constitutional guarantees
of due process and equal protection. Accordingly, we reverse the judgment of the appellate
court on counts II and III and affirm the judgment of the circuit court.

¶ 95 D. Count IV: Gender Equality
¶ 96 The Illinois Constitution provides in article I, section 18:
“The equal protection of the laws shall not be denied or abridged on account of sex
by the State or its units of local government and school districts.”
¶ 97 Plaintiffs asserted in count IV of their complaint that the Act violates this clause “by
preferencing childbirth over abortion, thus improperly advancing gender stereotypes about
the role of women as mothers.” The circuit court rejected this assertion, finding that there
was nothing in either the language or history of the Act which would lead it to conclude that
the purpose of the Act was to maintain the life of the fetus or to impose on minors
stereotypical views about womanhood.
¶ 98 The appellate court reversed the judgment of the circuit court and remanded for further
proceedings. Relying on this court’s decision in People v. Ellis, 57 Ill. 2d 127, 130 (1974),
Justice Gordon, in the lead opinion, found that the purpose of the gender equality clause is
“to guarantee rights for females equal to those of males.” 2011 IL App (1st) 101463, ¶ 115.
He then went on to hold:
“In the case at bar, the law discriminates between men and women by permitting
a minor male, without notifying his parents, to consent or withhold consent for a
surgical procedure for his child, even if that decision might endanger the health or
life of that child, while requiring parental notice for a minor woman seeking to abort.
Compare Consent by Minors to Medical Procedures Act (410 ILCS 210/1 (West
2008) (minor father ‘is deemed to have the same legal capacity to act’ as an adult))
with Parental Notice of Abortion Act (750 ILCS 70/15 (West 2008)). If a minor male
can make a life-endangering decision for his child, then certainly a minor female
should be able to make a similar decision for a fetus. If the male’s decision does not
require parental notification, then requiring parental notification for only the female’s
decision creates a gender-based distinction.” Id. ¶ 118.
¶ 99 Finding that strict scrutiny applied to this claim, Justice Gordon remanded to the circuit
court “to provide the State an opportunity to satisfy its burden under strict scrutiny review
of demonstrating a compelling state purpose.” Id. ¶ 114.

-24-
¶ 100 In a special concurrence, Presiding Justice Garcia stated, “I do not join in the author’s
suggestion that *** the Act ‘[improperly] discriminates between men and women.’ ” 2011
IL App (1st) 101463, ¶ 138 (Garcia, P.J., specially concurring). Nevertheless, Justice Garcia
joined in the decision to reverse and remand.7 Justice McBride, however, dissented in part,
stating: “I do not believe the allegations accepted as true and authority relied upon by
plaintiffs support the contention that the Act violates article I, section 18, of the Illinois
Constitution. Accordingly, I would affirm the trial court’s dismissal of count IV.” 2011 IL
App (1st) 101463, ¶ 136 (McBride, J., concurring in part and dissenting in part).
¶ 101 Before this court, plaintiffs urge us to affirm the appellate court’s reversal of the circuit
court’s dismissal of their gender equality claim. However, plaintiffs do not adopt Justice
Gordon’s reasoning. Instead, they argue, as they did in the circuit court, that the Act “furthers
discriminatory, gender-based stereotypes by permitting teens who conform to the view that
women must put childbearing and motherhood above all else to make their own decisions
about continuing their pregnancies and to consent to all medical care without state-mandated
parental or court involvement, while erecting dangerous barriers for those who, by seeking
an abortion, challenge this version of a woman’s role.” Plaintiffs contend further that because
the Act creates a gender-based classification (as described above), the appellate court was
correct to remand to the circuit court for consideration of whether the Act can survive strict
scrutiny.
¶ 102 Article I, section 18, of the Illinois Constitution of 1970 was first interpreted and applied
by this court in People v. Ellis, 57 Ill. 2d 127 (1974). At issue in Ellis was the
constitutionality of a provision of the Juvenile Court Act which provided that, in order to be
prosecuted under the criminal laws of the state, a boy had to be 17 years old, but that a girl
had to be 18 years old. We first determined that a sex-based classification was a “suspect
classification” which had to withstand strict scrutiny to be valid. We then invalidated the
provision of the Juvenile Court Act, finding that it created a sex-based classification and
there were no compelling reasons for the disparate treatment. Ellis, 57 Ill. 2d at 132-33; see
also Phelps v. Bing, 58 Ill. 2d 32, 35 (1974) (no compelling state interest which justifies
treating males and females of the same age differently for the purpose of determining their
rights to a marriage license).
¶ 103 In their brief, plaintiffs cite our decision in In re Estate of Hicks, 174 Ill. 2d 433 (1996).
However, we do not find that it advances their position. In Hicks, we considered the
constitutionality of section 2-2(d) of the Probate Act of 1975 (755 ILCS 5/2-2(d) (West
1994)), which permitted only mothers, and not fathers, to inherit by intestate succession from
their illegitimate children. We found that statute created a sex-based classification because
it distinguished between the parents of an illegitimate child based solely upon the gender of
the parent.

7
It is not clear what Justice Garcia intended when he stated that he disagreed with “the
author’s suggestion that *** the Act ‘[improperly] discriminates between men and women.’ ”
However, we follow the judgment line. Accordingly, we interpret Justice Garcia’s separate opinion
as a concurrence, resulting in a judgment of two to remand count IV.

-25-
¶ 104 In contrast to Hicks, in People v. Adams, 149 Ill. 2d 331 (1992), we rejected an argument
that section 5-5-3(g) of the Unified Code of Corrections (730 ILCS 5/5-5-3(g) (West 1992)),
which required, among other things, that persons who were convicted of the offense of
prostitution be tested for HIV, violated the gender equality clause of the Illinois Constitution.
We said:
“[W]e reject the alternative contention, made by the defendants and certain amici,
that the statute creates a sex-based classification because of its impact on female
offenders, and that it must therefore survive strict scrutiny under the Illinois
Constitution’s prohibition of sex-based discrimination (Ill. Const. 1970, art. I, § 18;
see People v. Ellis (1974), 57 Ill. 2d 127, 132-33). The statute draws no distinction
between male and female offenders, and the defendants point to no evidence of an
intent by the legislature to disadvantage female offenders. Accordingly, the additional
claim of disparate impact must be rejected.” (Emphasis added.) Adams, 149 Ill. 2d
at 352.
¶ 105 In the case at bar, we fail to see how the Act creates a sex-based classification or how the
alleged discrimination against pregnant minors who choose an abortion is in any way related
to their gender. Like the circuit court, we reject plaintiffs’ assertions that the Act “furthers
discriminatory, gender-based stereotypes.” We find no evidence that the Act’s purpose is to
deny pregnant minors their right to an abortion or to advance a preference for childbirth.
Furthermore, since we have already held that the Act does not violate equal protection, we
do not agree with plaintiffs that the Act discriminates against minor females who choose to
have an abortion. But even if we had agreed with plaintiffs’ premise, we would be compelled
to find no gender equality violation. The discrimination which is alleged is between different
classes of persons of the same gender. The gender equality clause of our constitution has
never been interpreted so broadly so as to apply in such situations.
¶ 106 For all of the reasons stated above, we find that the Act does not violate the gender
equality clause of our Illinois Constitution. Accordingly, we reverse the judgment of the
appellate court on count IV and affirm the judgment of the circuit court.

¶ 107 II. No. 112673
¶ 108 As noted above, shortly after plaintiffs filed suit against defendants in the circuit court
(No. 09 CH 38661), Stewart Umholtz, State’s Attorney of Tazewell County, and Edward
Deters, State’s Attorney of Effingham County (the proposed intervenors), petitioned the
circuit court for leave to intervene in the matter as of right, or by permission. The circuit
court, after dismissing plaintiffs’ complaint with prejudice, denied the proposed intervenors’
petition as moot.
¶ 109 The proposed intervenors appealed. On appeal, the appellate court reversed the circuit
court’s dismissal of plaintiffs’ complaint, but affirmed the circuit court’s denial of the
petition to intervene. The appellate court held:
“Since the proposed intervenors failed to demonstrate either inadequate
representation by the state’s Attorney General or an interest separate and apart from
either the general public or the existing parties, we find that the trial court did not

-26-
 abuse its discretion in denying their motion to intervene.” 2011 IL App (1st) 101463,
¶ 131.
¶ 110 The proposed intervenors then filed a petition for leave to appeal in this court, which we
allowed. However, we now find that we need not address the proposed intervenors’ appeal.
Because we have found that the Act does not violate our state constitutional guarantees of
due process, equal protection, privacy or gender equality, plaintiffs’ complaint was properly
dismissed with prejudice and there is no case in which to intervene. Thus, the circuit court
properly dismissed the proposed intervenors’ petition as moot.

¶ 111 CONCLUSION
¶ 112 We reverse that part of the appellate court’s judgment which reversed the circuit court’s
dismissal of plaintiffs’ complaint and remanded for further proceedings, but affirm that part
of the judgment which affirmed the circuit court’s denial of the petition to intervene. The
judgment of the circuit court, which dismissed the complaint and denied the petition to
intervene, is affirmed.

¶ 113 Appellate court judgment affirmed in part and reversed in part.
¶ 114 Circuit court judgment affirmed.

¶ 115 JUSTICE THOMAS, specially concurring:
¶ 116 I concur in the judgment of Justice Burke’s lead opinion holding that the Parental Notice
of Abortion Act of 1995 is not unconstitutional on its face and that all of plaintiffs’
challenges to the Act should be rejected. I write separately, however, to express my
disagreement with the lead opinion’s conclusion that the due process clause of the Illinois
Constitution contains a right to abortion that is coextensive with the right to abortion in the
federal constitution. I believe that the framers of our state constitution in 1970 specifically
chose not to create a right to abortion at all in our state constitution, but rather wanted to
leave the question of abortion regulation to the state legislature. Thus, I disagree with the
portion of the lead opinion that holds that there is a right to abortion under the Illinois due
process clause.
¶ 117 The due process clause in the Illinois Constitution of 1970 is found in article I, section
2, and provides as follows:
“No person shall be deprived of life, liberty or property without due process of
law ***.” Ill. Const. 1970, art. I, § 2.
This due process language is the same as article II, section 2, of the 1870 Illinois
Constitution. Additionally, the language of the clause basically tracks the fourteenth
amendment of the United States Constitution.
¶ 118 Generally, provisions in the Illinois Constitution that are similar in language to those in
the federal constitution will be similarly construed, unless we “find in the language of our
constitution, or in the debates and the committee reports of the constitutional convention,
something which *** indicate[s] that the provisions of our constitution are intended to be

-27-
 construed differently than are similar provisions in the Federal Constitution, after which they
are patterned.” People v. Caballes, 221 Ill. 2d 282, 297, 310 (2006) (quoting People v. Tisler,
103 Ill. 2d 226, 245 (1984)). This is the limited lockstep approach.8 “[O]ur choice of a rule
of decision on matters governed by both the state and federal constitutions has always been
and must continue to be predicated on our best assessment of the intent of the drafters, the
delegates, and the voters—this is our solemn obligation.” Caballes, 221 Ill. 2d at 313.
¶ 119 A perusal of the debates and committee reports of the constitutional convention leads
inexorably to the conclusion that the framers of the Illinois Constitution of 1970 did not
intend to incorporate a right to abortion in the due process clause of article I, section 2, or
anywhere else in the Illinois Constitution. Thus, I too reject plaintiffs’ suggestion that our
state constitution extends guarantees that are more protective of abortion than the federal due
process clause. But I would do so for the reason that the drafters did not intend to place a
right to abortion at all in our state constitution.
¶ 120 In the spring of 1970, the Bill of Rights Committee of the Sixth Constitutional
Convention voted 9 to 6 to add the phrase “including the unborn” after the word “person”
to the existing due process clause contained in the Bill of Rights of the Illinois Constitution
of 1870. 6 Proceedings 18. These three words were added “to assure that an unborn person
cannot be deprived of life, liberty or property by the State without due process of law.” Id.
at 19. A minority of the committee opposed this language. Their reasons for doing so are
determinative as to whether the drafters intended to embrace a right of abortion in the
language that was ultimately adopted.
¶ 121 The minority’s position, placed in a “Minority Report,” stated in relevant part as follows:
“It is our position that the chief, if indeed not the only, effect of these words is to
prohibit the General Assembly from enacting any laws to permit abortions, except
presumably abortions which are now permitted under Illinois law where necessary
to preserve the life of the mother. It seems clear that this has to be the effect if the
words in question are to be given any significance whatsoever.
***
It is the minority’s position that the subject of abortion law should be left to the
legislature, which can study and evaluate the pertinent medical and social facts and
policy consideration.
***
The subject of abortion law should be left to the legislature. This Constitutional
Convention is not equipped to study the pertinent medical or social facts or weigh the
competing policy considerations which bear on the question of what kind of abortion
law Illinois should have.
It is the further position of the minority that if the Convention should decide that
the subject of abortion ought to be dealt with in the Constitution, this should be

8
This approach has been modified to include “consideration of state tradition and values as
reflected by long-standing state case precedent.” Caballes, 221 Ill. 2d at 314.

-28-
 accomplished by means of a separate section dealing directly and explicitly with the
subject.” (Emphases added.) Id. at 130-35.
¶ 122 The issue then went to the convention floor for the full delegation to consider the
question of whether the language “including the unborn” should be retained or deleted.
Delegate Arthur Lennon began by presenting the majority position that the additional
language should be retained. 3 Proceedings 1496-1501. He asserted that “due process only
has application to actions by the state in relationship to individuals.” (Emphasis added.) Id.
at 1496. Thus, it was his view that the majority’s version did not apply to private conduct,
but only to state action such as a compulsory abortion law, where, for example, the
legislature might order that all pregnant women have an abortion. Id. at 1502. He stated that
the addition of the words was “intended to limit the state from compelling the taking of a
human life,” but did not otherwise apply to prevent a women from having an abortion.
Instead, the criminal sanctions, if any, set by the legislature would govern that situation. He
also discussed Illinois case law at length and asserted that the trend was to find an unborn
child to be a “person” for many purposes under the law—such as inheritance, tort and
criminal law—and he inferred that Illinois courts would likely hold that the word “person”
in the Illinois due process clause would include an unborn child even in the absence of
“including the unborn” language. Id. at 1497-99.
¶ 123 Delegates Lewis Wilson and Bernard Weisberg, who were both members of the Bill of
Rights Committee and two of the five signers of the minority proposal to remove the words
“including the unborn,” then presented the minority position. Delegate Wilson began by
emphasizing that the purpose of the addition of the three words was to prohibit the General
Assembly from allowing some or all abortions:
“This, the minority believes, is plain and obviously an attempt to strengthen the due
process clause which now protects all persons so as to make it perfectly clear under
the due process clause that any liberalization of abortion—any liberal abortion
law—would run into this further obstacle in the due process clause of the three
words, ‘including the unborn.’ ” Id. at 1504.
He then left no doubt regarding the legislature’s continuing authority to prohibit and/or
regulate abortion under the minority proposal:
“I want to make clear the position of the minority. It is the position of the minority
that the legislature should be left free to deal with the question of abortion under the
due process clause as it now stands, and that no further impediments on the power
of the legislature to act freely should be inserted in the due process clause in the form
of these words. It is not the position of the minority that the constitution should speak
to the question of abortion by putting into the constitution some provision that
presumably would authorize or make more constitutional, if you please, the
enactment of what I will refer to as liberalized abortion laws. It is our position that
the constitution should not address itself to the question of abortion at all, but that
this should be left to be acted upon by the legislature under the existing language of
the due process clause.
***

-29-
 *** The legislature, I think, has shown the capacity and the will to act in the field
of abortion law; and we feel perfectly confident in leaving this to the legislature and
not trying to constitutionalize it. There are too many imponderables. The whole
subject is too dynamic and too volatile. This is not like freedom of speech or freedom
of worship. We will never want the legislature to have the right there to do away with
freedom of worship or freedom of speech or those kinds of rights, but this is a
different sort of subject. It is volatile; it’s dynamic; the world is changing; and we
feel that this should be left to the legislature.” (Emphases added.) Id. at 1504-05.
¶ 124 Parenthetically, I note that three different attempts were made in February 1970 to have
the Bill of Rights of the 1970 Constitution specifically include the right to abortion in one
form or another. All three attempts were defeated. In that regard, Member Proposal No. 387
would have provided that “[t]he State shall make no law decreeing who is to be born or who
is to die.” 7 Proceedings 3012. Member Proposal No. 407 would have provided that “[n]o
penalty may be imposed by law upon any person in connection with an abortion performed
by a licensed physician with the consent of the woman upon whom it is performed and, if she
is an unmarried minor, the consent of her parents or guardian.” Id. at 1321. And finally,
Member Proposal No. 506 would have provided that “any female by giving her consent and
approval shall not be denied the right to comply with advice given by qualified medical
authorities.” Id. at 3069. Again, all three of these proposals that would have
constitutionalized the right to abortion were defeated.
¶ 125 Returning to the presentations on the floor with respect to the minority proposal, I note
that Delegate Weisberg echoed the intent expressed by Delegate Wilson:
“The minority believes that, as Lew Wilson has pointed out, that this subject is
peculiarly appropriate and necessary to leave to the legislature. There are serious
problems here. It has been pointed out more and more frequently in recent years that
there are serious medical and social problems which the Constitutional Convention,
we submit, is not equipped to study and evaluate.” (Emphasis added.) 3 Proceedings
1505.
Delegate Weisberg concluded his remarks by reading from the minority report to emphasize
that he believed the addition recommended by the majority “would create a divisive and
emotional issue in the referendum campaign” for voter approval. Id. at 1506.
¶ 126 Following questioning of the presenters of the minority position, the floor was then
opened for debate. Delegates from both sides of the issue rose to speak—and opinions were
expressed both for and against constitutionalizing due process protection for an “unborn
person.” Id. at 1509-21. Some expressed the belief that the word person in the existing
Illinois constitution already protected the “unborn.” Id. at 1521-22 (see comments of Mrs.
Kinney and Mr. Ladd).9 Others expressed the view that the specific reference to the unborn

Mrs. Kinney explained her “yes” vote to delete the “including the unborn” language by
stating, that, “If we speak of an unborn person, haven’t we said it all when we simply say ‘person’?”
She also stated that she wished to set the record straight that by voting to delete the language, she
did not believe that she or the delegation was voting in favor of legalized abortion. Id. at 1521.

 was necessary to combat the “reprehensible” theory that some witnesses presented to the
committee that advocated abortion as a form of population control for an overcrowded state.
See id. at 1512-13.
¶ 127 Delegate Albert Raby, also a member of the Bill of Rights Committee and a signer of the
minority report, rose to explain his position and to explain that the constitutional convention
was not “in the mood” to in any way tie the hands of the legislative branch or prevent it from
acting with respect to abortion:
“I’d like the record to show that if I had my way in this Convention we would write
a constitutional provision which would establish—which would prevent the
legislature from writing any laws that dealt with the question of whether a woman
could or could not have a child. It was very early in the game that I recognized that
our committee—and I came to grips with the fact that the Convention was not in a
mood to do that. ***
***
While I would hope that this Convention would have faced this issue
squarely—would have included in the constitution a prevention from the legislature
acting on this matter—I am—I recognize that that is not possible, and I support the
*** minority—report and strongly suggest that it ought to be supported ***.” Id. at
1514.
¶ 128 Delegate Cliff Kelley, the drafter of Member Proposal No. 407 that would have placed
the right of abortion in the Bill of Rights of our 1970 constitution, also urged that the matter
be left to the legislature:
“On February 26 of this year I offered to the Convention Member Proposal No.
407, which ***
Proposes that the legislature be precluded from imposing any penalty in
connection with an abortion performed by a licensed physician with the consent
of the woman upon whom it is performed ***.
Whereas this proposal reflects my philosophy in regard to abortion, I am not at
this time suggesting that we adopt such. I am suggesting that we not preclude the

There is certainly support for the view that many delegates believed that the word “person” in the
existing Illinois due process clause of 1870 would be or had already been interpreted to include an unborn
child from the time of his or her conception. Delegate Wilson, a presenter of the minority report, told the
delegation during the debate that it was their position “that the unborn person is now protected as are other
persons by the due process clause as it’s been written and as it’s stood for 100 years or so, and that nothing
further is needed as far as the due process clause is concerned.” Id. at 1507-08. This was indeed the view
taken with respect to the federal due process clause in Steinberg v. Brown, 321 F. Supp. 741, 746-47 (N.D.
Ohio 1970), where the court held that “[o]nce human life has commenced [at conception], the constitutional
protections found in the Fifth and Fourteenth Amendments impose upon the state the duty of safeguarding
it.”
At any rate, whether the word “person” in the Illinois due process clause includes an unborn child
is a separate question, and we do not address it here.

 General Assembly from enacting such legislation in the future. Of course, it has been
suggested to me by many people that the General Assembly *** in its conservatism
will never adopt such legislation anyway, but that remains to be seen.” Id. at 1516.
¶ 129 Delegate Elward, a supporter of the majority position, also addressed the convention. He
offered some prescient remarks that in some respects foresaw the present litigation:
“It is said in some circles we should leave this to the General Assembly, but those
people who this afternoon tell you to leave it to the General Assembly will tomorrow
morning file the lawsuit that says the General Assembly should have no power to
deal with this question. They seek by court action to overturn what the General
Assembly has or has not done. *** They don’t trust this Convention; they don’t trust
the General Assembly ***.” Id. at 1517.
¶ 130 After all the delegates were heard that wished to speak in the debate, a roll call was called
by the clerk. It was explained that those who wanted to strike the words “including the
unborn” would vote aye or yes. And those who wanted to preserve those words would vote
nay or no. The vote tally was 80 ayes to 32 nays, and the “including the unborn” language
was deleted.
¶ 131 A number of delegates spoke to the convention to explain their vote. It seems that a great
number of delegates voted “yes” to defeat the inclusion of the “unborn” language, even
though they were “sympathetic” to the majority report or were in favor of strict abortion
laws. The remarks of Delegate MacDonald seem representative of many, when she said that
she voted yes because she believed the convention was leaving abortion-related issues “to
the legislature and not to this constitution.” See, e.g., id. at 1522.
¶ 132 I would submit that we can easily conclude from the drafter’s rejection of the “including
the unborn” language that the drafters did not want to tie the hands of the legislative branch
from enacting laws that would allow some or all abortions. Similarly, we can conclude from
the drafter’s rejection of the proposals to specifically include the right to abortion in the
constitution that the drafters did not want to tie the hands of the legislative branch from
enacting laws that would prohibit some or all abortions. The rejection of these competing
proposals itself indicates that the constitutional delegates wanted to leave the regulation of
abortion to the legislature.
¶ 133 This intent of our drafters is clearly different from the holding 22 years later in Planned
Parenthood of Southeastern Pennsylvania v. Casey, 505 U.S. 833 (1992), which located a
right to abortion in the federal due process clause and which reaffirmed the central tenet of
Roe v. Wade, 410 U.S. 113 (1973), that a woman has a right to abortion under the federal
constitution before viability “without undue interference from the State.” So the reality here
is that the intent of our drafters was contrary to Casey. I would not apply lockstep here,
where following Supreme Court precedent as to the federal provision would lead to a result
that is different from what the framers intended our own state constitution’s cognate
provision to mean. The drafters specifically refused to modify our state constitution to limit
the legislature’s authority to restrict abortion or prohibit it outright. Instead they expressed
a strong intent to leave the matter of abortion regulation to our state legislature.
¶ 134 The situation here in applying the Caballes limited lockstep approach is a unique one.

-32-
 By the time of the constitutional convention’s debate in 1970, what the delegates called
“liberalized abortion laws”—that is, laws that would legalize abortion well beyond the
traditional limit of only when necessary to save the life of the mother—were being proposed
in some quarters. The Supreme Court of the United States, of course, had not yet ruled that
there was a right to abortion under the federal constitution; that would not come for three
more years with the Court’s ruling in Roe. Thus, the drafters were working with a blank slate
and yet were well aware of their options with respect to the question of abortion. They fully
considered the question and made their intent clear. They wanted to leave the area of abortion
regulation in Illinois to the General Assembly. They specifically did not want to memorialize
in the Illinois Constitution either a right to an abortion on the one hand or the specific
mention of the right to life for the unborn on the other. Instead, they found that the area of
abortion regulation was “peculiarly appropriate and necessary to leave to the legislature.” Id.
at 1505 (statements of Delegate Weisberg). They specifically recognized that the question
represented the kind of serious medical and social problem that the constitutional convention
was not equipped to study and evaluate. They wanted to exercise restraint from controlling
the matter and wanted to leave it to the democratic process for resolution. Thus, there is
clearly an intent at work here for our state constitution’s due process clause to be construed
differently on this matter than the federal constitution as construed by the United States
Supreme Court in 1992 in Casey.
¶ 135 Justice Burke concludes that the mere fact that our due process clause remained
unchanged from the 1870 Constitution means that there is “nothing” in the debates or
committee reports that demonstrates that our due process clause is to be construed differently
than the federal due process clause with respect to abortion. Supra ¶ 55. As my preceding
discussion demonstrates, Justice Burke’s conclusion is patently false. The framers of the
1970 Constitution clearly regarded the issue of abortion regulation as a legislative matter, not
a due process matter, a position that is fundamentally at odds with the way in which the
federal courts subsequently construed the federal due process clause. On this question, the
two provisions simply do not mean the same thing.
¶ 136 There is nothing in the constitutional debate to suggest that the drafters were concerned
specifically with conforming our state’s due process clause with the federal clause. Rather,
there is a comment suggesting that some wanted to keep the “existing language of the due
process clause,” by which the delegates meant the existing language in our state constitution
of 1870, which of course was the governing constitution in effect in the State of Illinois at
the time. Keeping the “existing language” meant only that they wanted to delete the words
“including the unborn” that the majority of the committee had drafted. There was no
intention expressed by the constitutional delegates to have the state and federal provisions
interpreted similarly with respect to the question of whether the legislature should have the
ultimate power to regulate abortion. Instead, the intention of the delegates, as expressed in
the debate, was just the opposite. The debate indicates that the drafters intended to leave the
legislature free to regulate or prohibit abortion. Again, this intent is opposite of Casey and
Roe, which eradicates, or at least severely limits, a state legislature’s ability to regulate or
proscribe abortion.
¶ 137 Of course, “[t]he meaning of a statute or constitutional provision depends upon the intent

-33-
 of the drafters at the time of its adoption, and it is a long-standing principle of statutory
construction that it is the court’s duty to ascertain and effectuate that intent.” (Emphasis
added.) Sayles v. Thompson, 99 Ill. 2d 122, 125 (1983). That the drafters of our constitution
in 1970 would specifically want to leave the matter to the legislature makes perfect sense
given our state history with respect to abortion law up until that time.
¶ 138 By the time of the adoption of our constitution in 1970, it had been the continuous public
policy of this state for over 140 years to protect unborn human life by prohibiting abortion.
From 1827 until 1973, except for a brief period between 1867 and 1874 when abortion was
allowed “for bona fide medical or surgical purposes” (Act of Feb. 18, 1867, Ill. Laws § 89
(1867)), Illinois prohibited abortion at any stage of pregnancy unless the mother’s life was
endangered. See People ex rel. Hanrahan v. White, 52 Ill. 2d 70, 73 (1972) (citing various
Illinois abortion statutes going back to 1845); see also Ill. Rev. Laws at 131 (1827); Ill. Rev.
Laws at 179 (1833). After the 1970 Constitution went into effect and before Roe was
decided, this court refused to graft psychiatric or mental-health exceptions onto the statute,
specifically noting that the legislature had repeatedly rejected bills that would have allowed
abortions for such reasons. White, 52 Ill. 2d at 73-75. When, after the United States Supreme
Court decided Roe, this court declared the Illinois abortion law unconstitutional in People
v. Frey, 54 Ill. 2d 28 (1973), it did so strictly on the basis of the supremacy clause in the
federal constitution, and not upon any independent state ground. See Paul Benjamin Linton
& Kevin J. Todd, Abortion Under the Illinois Constitution: The Framers Did Not
Incorporate a Right to Abortion, 81 Ill. B.J. 31, 34 (1993).
¶ 139 The Illinois General Assembly repealed our pre-Roe abortion laws in 1973, but in 1975
enacted laws attempting to regulate abortion within the narrow parameters allowed by Roe.
The statement of legislative intent in the Illinois Abortion Law of 1975, which intent
continues to this day, provides in part as follows:
“[T]he General Assembly finds and declares that longstanding policy of this State to
protect the right to life of the unborn child from conception by prohibiting abortion
unless necessary to preserve the life of the mother is impermissible only because of
the decisions of the United States Supreme Court and that, therefore, if those
decisions of the United States Supreme Court are ever reversed or modified or the
United States Constitution is amended to allow protection of the unborn then the
former policy of this State to prohibit abortions unless necessary for preservation of
the mother’s life shall be reinstated.” 720 ILCS 510/1 (West 2010) (formerly Ill. Rev.
Stat. 1977, ch. 38, ¶ 81-21).
¶ 140 In sum, I believe that delegates to the Sixth Illinois Constitutional Convention refused
to recognize a right to abortion in drafting our 1970 constitution, and that is how I would
construe our due process clause. Given the clear intent of the drafters of our 1970
constitution, I would reject the lockstep approach that the lead opinion employs in construing
the language of our due process clause to mean the same as the federal due process clause
on the subject of abortion. In the end, however, we are in unanimous agreement that the
Illinois due process clause does not render the Parental Notification of Abortion Act of 1995
unconstitutional. I believe we also wind up in the same place in the event that Casey and Roe
are ever overruled. If that were to happen, the lead opinion’s approach would simply revert

-34-
 the meaning of our due process clause to the pre-Roe interpretation and the matter of abortion
regulation (i.e., whether to regulate or prohibit it) would be left for the legislative process.
Although it may seem to be an academic point, then, to conclude, as I do, that the Illinois
Constitution does not contain a right to abortion, it is our solemn obligation to discern and
effectuate the true intent of the drafters of our state constitution on this matter.
