concurring.
¶ 1 The court affirms the denial of unemployment benefits to plaintiff Gilchrist on the grounds that (a) her conduct as a forensic chemist in several criminal prosecutions1 constitutes a § 2-4062 “misconduct” as that term has been construed by extant jurisprudence 3 and (b) her First Amendment right to speak freely does not insulate her from the adverse consequences of her testimonial misconduct.
¶ 2 I concur in today’s decision and in the court’s pronouncement. I write separately (a) to explain why Gilchrist cannot interpose here her immunity from civil liability as a criminal prosecution witness to prevent the imposition of adverse collateral consequences of her testimonial conduct upon her claim to unemployment benefits and (b) to focus on her argument that judicial denial of governmental benefits was predicated upon a constitutionally impermissible condition.

PLAINTIFF APPEARS TO ARGUE THAT HER COMMON-LAW IMMUNITY AS A WITNESS PROTECTS HER FROM GOVERNMENT USE OF HER TESTIMONY TO SHOW MISCONDUCT
¶ 3 Gilchrist appears to rely on and invoke the common-law rule that shields witnesses from civil liability for any harm occasioned *77by testimony given in court proceedings. She claims there is no record support for the judicial analyses in certain state and federal criminal cases4 to show her testimony to have been improper, inaccurate or misleading. According to Gilchrist, the denial of unemployment benefits rests on a mere disagreement with the content of her testimony.
¶ 4 Assuming Gilchrist is not guilty of perjury and taking due notice of her protection as a witness, the immunity she invokes extends no farther than to shield her from civil liability for harm occasioned by the testimony. It cannot be stretched to cover all collateral public-law consequences5 that adversely affect her claim to governmental benefits.
The Outer Limit of Witness Immunity
¶ 5 At common law witnesses were immune from suits to recover damages for harm occasioned by testimony given in judicial proceedings.6 Federal constitutional jurisprudence has extended witness immunity to civil suits brought under 42 U.S.C. § 1983.7 Oklahoma has long recognized that lawyers, parties and witnesses are immune from defamation and certain other claims rested upon communications made during, or preliminary to, judicial proceedings as long as the communication is in some way relevant to the proceeding.8 Recent Oklahoma jurisprudence has extended the witness immunity shield to protect against tort actions for damages occasioned by one’s perjury (but not to criminal prosecutions for perjury).9
*78¶ 6 Adverse collateral public-law consequences of a witness’ testimony, such as those flowing from a criminal prosecution for perjury, professional discipline, and from other forms of censure and sanction, fall outside the ambit of witness immunity. That immunity will not protect an attorney from professional discipline based on unethical conduct resulting in defamation.10 A number of states and the federal government have imposed professional discipline on lawyers for perjury and other litigation-related misconduct, holding that these consequences, though immunized from civil liability, nonetheless lie dehors the witness immunity shield.11 Others have indicated (in dicta) that an attorney remains subject to professional discipline for litigation-related misconduct even where redress by civil action is unavailable because of witness immunity.12
The Adverse Consequence of Gilchrist’s Breach of Public-Employment Duty To Maintain Scientific Inteyrity In Her Work Performance
¶ 7 While employed as a police department’s forensic chemist, Gilchrist had a duty to maintain scientific integrity in her work. Obedience to this level of performance is exacted by the public-law standards that govern constitutional strictures for guilt determination in criminal prosecutions. That duty’s breach is now advanced as misconduct (in the § 2-406 sense) to defeat her claim for unemployment compensation. Gilchrist’s witness immunity13 will not protect her against this adverse consequence of public employment. Shielded by that immunity is solely civil liability in damages for harm occasioned by one’s testimonial falsehood.
¶ 8 In short, the denial of unemployment benefits is a sanctioned adverse collateral *79public-law consequence of Gilchrist’s testimonial improprieties.14
II
GILCHRIST APPEARS TO ARGUE THAT THE GOVERNMENT’S USE OF HER TESTIMONY TO SHOW “MISCONDUCT” (IN THE § 2-406 SENSE) OFFENDS THE FIRST AMENDMENT’S FREE-SPEECH CLAUSE PROTECTION AGAINST HAVING HER CLAIM TO UNEMPLOYMENT BENEFITS BURDENED BY AN UNCONSTITUTIONAL CONDITION
¶ 9 Gilchrist claims that the denial of unemployment benefits based on mere judicial disagreement with the content of her testimony as an expert witness in criminal cases infringes upon her First Amendment right to speak freely. Relying on Worrell v. Henry15 and other federal circuit jurisprudence,16 she argues that the denial of benefits cannot be rested on a constitutionally impermissible condition — one that places a penalty on her exercise of free-speech guarantee.17 She reasons and urges that the denial of unemployment benefits based on her testimony as an expert witness constitutes government censorship and violates her protected freedom of expression on matters of public concern.
¶ 10 The First Amendment is not implicated here. The government’s scrutiny of her testimony for its lack of support in elicited scientific data does not offend the First Amendment’s Free Speech Clause. Much like commercial speech,18 testimony must always conform to the reality of established facts. Neither does the use of judicial analyses of Gilchrist’s testimonial impropriety (in the discharge of her employment duties) offend constitutional protection of her utterance from government retaliation. Disapproval here comes from her testimony’s failure to meet the minimum standards of scientific integrity. The government did not tender these analyses for any purpose other than to show her substandard professional performance as a forensic analyst. No constitutional barrier, federal or state, has been identified to prohibit the use of judicial analyses of a public *80employee’s expert testimony as proof of unacceptable job performance. Moreover, government’s demonstration of legitimate problems adversely affecting an employee’s discharge of public employment duties cannot be mistaken for a constitutionally impermissible retaliatory response. No one would dare deny that the government has a compelling interest in maintaining acceptable job performance standards for its personnel.
¶ 11 Conditioning a public employee’s claim to a governmental benefit on conformity to the norms of scientific integrity in carrying out her day-to-day work duties does not place a constitutionally prohibited burden on its benefit. In sum, the claim-burdening condition of which Gilchrist complains is clearly authorized' — nay, mandated — by this Nation’s highest norms of federal law — its regime of constitutional strictures that govern the process of guilt determination in criminal prosecutions.

. Adverse public-law consequences are all those which constitute the collateral effect of judgments or convictions. For example, nondis-chargeability in bankruptcy is a collateral adverse consequence of a civil judgment based on fraud and deceit or of a judgment for child support. There are many adverse collateral consequences of a felony conviction, such as the loss of right to vote, eligibility for citizenship, national security clearance, as well as licensing and employment-related restrictions, disqualification from military service or from holding public office. The loss of a driver's license is another collateral consequence of some criminal convictions.

. The immunity of parties and witnesses from liability in damages for giving harmful testimony in judicial proceedings was established early in the English common law. See Briscoe v. LaHue, 460 U.S. 325, 330-31, 103 S.Ct. 1108, 1113, 75 L.Ed.2d 96 (1983), in which the Court cites Cutler v. Dixon, 76 Eng. Rep. 886 (K.B.1585) and Anfield v. Feverhill, 80 Eng. Rep. 1113 (K.B.1614) as early English authority for the immunity doctrine.

Haynes, 1990 OK 8, 788 P.2d 941 (the immunity doctrine (a) applies not only to defamation suits, but also to suits for intentional infliction of emotional distress arising from the same circumstances as the defamation claim, and (b) encompasses communications made preliminary to judicial or quasi-judicial proceedings). See also Pacific Employers Ins. Co. v. Adams, 1946 OK 86, 168 P.2d 105 (statements made in a physician's report attached to pleading filed in the State Industrial Court are immune); Hughes v.

. Cooper v. Parker-Hughey, 1995 OK 35, 894 P.2d 1096, 1098. There the court identified the following public-policy reasons for rejecting perjury as a tort: (1) absolute immunity for witnesses in a judicial proceeding encourages witnesses to speak freely without fear of civil liability; (2) perjury is a public offense and regulated solely by criminal law; (3) the need for finality in judgments, (4) the possibility of a multiplicity of suits by parties dissatisfied with the outcome of trials, and (5) lack of precedent for such actions. Id. at ¶ 27, at 1101. The court relied heavily on the reasoning expressed in Briscoe, supra note 6, a 1983 United States Supreme Court decision in which convicted defendants brought a civil rights action against police officers who testified against them, alleging that the officers violated the defendants' constitutional rights to due process and a fair trial by falsely testifying that the criminal defendants had been able to harmonize their stories, thereby rendering the exculpatory *78statements of each criminal defendant less credible.

Gabage, 280 N.J.Super. 125, 654 A.2d 1002, 1007 (N.J.Super.Ct.App.Div.1995) (the absolute privilege applies only to claims of tortious conduct and not to a claim of unprofessional conduct or to summary contempt proceedings against the offending lawyer).
. There are various types of immunities — testimonial immunity, immunity from suit (legislative, executive, judicial, or diplomatic), immunity from civil liability, immunity from prosecution, as well as use immunity. Use immunity prohibits the use of compelled testimony or any evidence derived from that testimony against the witness in a criminal prosecution. If evidence is compelled under a grant of immunity and there is a later prosecution, the government has the burden of demonstrating that "the evidence it proposes to use is derived from a legitimate source wholly independent of the compelled testimony.” Kastigar v. United States, 406 U.S. 441, 452-53, 92 S.Ct. 1653, 1653, 32 L.Ed.2d 212 (1972) (to preserve the witness’ privilege against self-incrimination, the prosecution is precluded from using against the defendant any responsive testimony elicited from him or any evidence derived therefrom).
. The Oklahoma Security Commission relied for proof of Gilchrist’s misconduct on the judicial analyses of her testimony in Mitchell v. Ward, 150 F.Supp.2d 1194 (W.D.Okl.1999); Mitchell v. Gibson, 262 F.3d 1036 (10th Cir.2001); McCarty v. State, 1995 OK CR 48, 904 P.2d 110; Cannon v. Gibson, 259 F.3d 1253 (10th Cir.2001); Pierce v. State, 1990 OK CR 7, 786 P.2d 1255; Ables v.

. 219 F.3d 1197, 1209 (10th Cir.2000). In Wor-rell the court held that a prosecutor's office did not offend the First Amendment when it rescinded an offer to hire an individual to be a drug task force coordinator because he had testified as an expert defense witness in a murder trial. A district attorney's interest in maintaining an efficient drug task force outweighed the applicant's interest in avoiding retaliation for his testimony as an expert witness against a police officer. Announcing a three-part standard for evaluating First Amendment retaliation claims, the court stated that a plaintiff must prove (1) that the plaintiff "was engaged in constitutionally protected activity”; (2) that the defendant's actions caused the plaintiff "to suffer an injury that would chill a person of ordinary firmness from continuing to engage in that activity”; and (3) that the "defendant’s adverse action was substantially motivated as a response to the plaintiff's exercise of constitutionally protected conduct.” Id., at 1212.

. Gilchrist claims that Melton, supra note 16, and Worrell, supra note 15, are applications of the doctrine against placing constitutionally impermissible conditions on one’s right. For this doctrine, she quotes Board of County Commissioners v. Umbehr, 518 U.S. 668, 674, 116 S.Ct. 2342, 2347, 135 L.Ed.2d 843 (1996). The "modern 'unconstitutional conditions’ doctrine holds that the government 'may not deny a benefit to a person on a basis that infringes his constitutionally protected ... freedom of speech’ even if he has no entitlement to that benefit.” Id., quoting Perry v. Sindermann, 408 U.S. 593, 597, 92 S.Ct. 2694, 2697, 33 L.Ed.2d 570 (1972).
