delivered the Opinion of the Court.
The People appeal an order of the Mesa County District Court dismissing the prosecution of Thomas M. Holmes. The People charged Holmes with the unlawful introduction of contraband into the Mesa County Detention Facility in violation of section 18-8-204(2)©, 6 C.R.S. (1997). Holmes moved to dismiss the charge, asserting that section 18-8-204(2)©, on its face, violates the Colorado Constitution because it constitutes an impermissible delegation by the General Assembly of its legislative powers to administrative heads of detention facilities. The trial court agreed with this contention and granted Holmes’s motion to dismiss.
We affirm the judgment of the trial court, but on grounds different from those employed by that court. We hold that section 18 — 8—204(2)(Z) is constitutional on its face. We also hold, however, that the Mesa County Detention Facility failed to comply with the notice requirements of that statute. Thus, we affirm the trial court’s order of dismissal.
I.
Holmes is an attorney practicing in Mesa County. The People allege that on July 11, 1996, Holmes went to the Mesa County Detention Facility (“MCDF”) to visit David Ta-foya, an MCDF inmate who was a client of Holmes. According to an MCDF employee, she searched Holmes’s briefcase prior to his entry into a secured area of the facility and discovered cigarettes, matches and two cigarette lighters. The employee, after advising Holmes that he was not allowed to take these items into the facility, temporarily confiscated the items. The MCDF employee did not provide Holmes with the reason behind the MCDF’s.prohibition of the items.
According to the People, Holmes again visited Tafoya at the MCDF on July 22,1996. The People allege that, after meeting with Holmes, Tafoya was found in possession of a legal envelope bearing the name of Holmes’s law firm. According to the People, an MCDF deputy searched the envelope and discovered a plastic bag containing cigarettes and a book of matches. Tafoya stated that he found the bag on the floor of the visitation room. The People claim that the last attorney-client visit occurred over five hours prior to Holmes’s visit with Tafoya, and that MCDF officials observed no cigarettes or matches in the visitation room prior to Holmes’s visit.
On August 29, 1996, the People charged Holmes with introducing contraband into the detention facility on July 22, in violation of section 18-8-204 (the “Contraband Statute”). In relevant part, the Contraband Statute provides that “a person commits introducing contraband in the second degree if he know*409ingly and unlawfully ... introduces or attempts to introduce contraband into a detention facility.” § 18-8-204(l)(a). In addition to listing specific items that are contraband for purposes of the statute, the statute defines contraband as “[a]ny article or thing that poses or may pose a threat to the security of the detention facility as determined by the administrative head of the detention facility if reasonable notice is given that such article or thing is contraband.” § 18-8-204(2)©. By the terms of the statute, the “reasonable notice” requirement applies only to those items of contraband described in section 18-8-204(2)©, and not to the items listed in section 18-8-204(2)(a)-(k).
On February 10, 1997, Holmes moved to dismiss the charge. In his motion, Holmes argued, inter alia, that the Contraband Statute impermissibly delegates legislative power to the administrative heads of detention facilities. More specifically, Holmes asserted that the Contraband Statute gives an administrative head “unbridled authority to declare conduct criminal” in violation of the Colorado Constitution as interpreted by this court. Holmes also contended that the administrative head of the MCDF did not determine that cigarettes and matches pose or may pose a security threat as required by the Contraband Statute. Finally, Holmes argued that the MCDF did not provide reasonable notice that cigarettes and matches are contraband under the statute.
On May 31, 1997, the trial court granted Holmes’s motion to dismiss. The trial court held that the Contraband Statute is unconstitutional on its face because it does not provide sufficient standards and safeguards to prevent the “unreasonable exercise of discretionary power” by the administrative heads of detention facilities. The trial court ruled that, because it allows an administrative head to declare an item contraband under the statute upon determining only that the item “may pose” a security risk, the Contraband Statute is “virtually standardless since ... virtually anything ‘may pose’ a risk.” Furthermore, the trial court found it significant that “[t]here is no uniformity with respect to what is permitted from one facility to another, and no uniformity with regard to the notice that is given from facility to facility” because “the determination under the contraband statute is not made on a state-wide basis.”
Thus, the trial court concluded that “the lack of specificity in the legislative standards coupled with the lack of administrative standards and safeguards” rendered the Contraband Statute an unconstitutional delegation of legislative authority. The People now appeal the trial court’s order pursuant to section 16-12-102(1), 6 C.R.S. (1997), and section 13-4-102, 5 C.R.S. (1997). Although we disagree with the trial court’s analysis, we affirm its judgment. See generally State v. Franc, 165 Colo. 69, 76, 437 P.2d 48, 51 (1968) (“[Wjhen the trial court enters a correct judgment for the wrong reason we -will nevertheless affirm it.”); People v. Hilton, 902 P.2d 883, 887 (Colo.App.1995) (“A correct decision will not be disturbed upon review even though the reason for the decision may appear to be incorrect.”).
II.
The Colorado Constitution divides the powers of government into three departments: the legislative, executive and judicial. See Colo. Const, art. III. The constitution provides that “no persons or collection of persons charged with the exercise of powers belonging to one of these departments shall exercise any power properly belonging to either of the others, except as in this constitution expressly directed or permitted.” Colo. Const, art. Ill; see also People v. Lowrie, 761 P.2d 778, 780-81 (Colo.1988). The constitution vests the legislative power of the state in the General Assembly. See Colo. Const, art. V, § 1. The “nondelegation doctrine,” rooted in the constitutional separation of powers, prohibits the General Assembly from delegating the legislative power to another department of government or person. See Lowrie, 761 P.2d at 781.
However, the reach of the nondelegation doctrine is limited by the fact that “[rjegulation through administrative agencies is an accepted part of our legal system.” Swisher v. Brown, 157 Colo. 378, 387, 402 P.2d 621, 626 (1965). The General Assembly does not improperly delegate its legislative *410power “when it describes what job must be done, who must do it, and the scope of his authority.” Swisher, 157 Colo. at 388, 402 P.2d at 626; see also Lowrie, 761 P.2d at 781.
In the context of a criminal statute, the nondelegation doctrine requires a closer examination of the legislature’s actions. See People v. Lepik, 629 P.2d 1080 (Colo.1981); Casey v. People, 139 Colo. 89, 336 P.2d 308 (1959). In Lepik, we held:
It is a fundamental principle that only the General Assembly may declare an act to be a crime and that power may not be delegated to persons not elected by nor responsible to the People. Although the power to make a law may not be delegated, the power to determine a state of facts upon which the law depends may be delegated .... The General Assembly must prescribe sufficient safeguards by which the power delegated is to be exercised; otherwise, the delegation of power is invalid as violative of the separation of powers.
629 P.2d at 1082 (citations omitted). We carefully scrutinize a statutory scheme that establishes criminal penalties for violation of administrative rules because such a delegation implicates an important liberty interest, including the right to reasonable notice of that conduct deemed criminal. See Lowrie, 761 P.2d at 781. A statute must prescribe standards sufficient to guide and to circumscribe an administrative officer’s authority to declare conduct criminal.
In Cottrell v. City & County of Denver, we explained that, in addition to a review of statutory standards and safeguards, the nondelegation doctrine analysis may include a review of administrative standards and safeguards. 636 P.2d 703, 708-10 (Colo. 1981). If a court determines that the statutory standards and safeguards are inadequate to prevent the unfettered exercise of discretionary power by an administrator, the court should then determine whether “additional administrative standards and safeguards accomplish the necessary protection from arbitrary action.” Id. at 710. If the statutory standards and safeguards provide this protection, however, a court need not proceed to examine any administrative standards or safeguards which may be in place.
In accord with the principles described above, we now examine the constitutionality of the Contraband Statute.
III.
In reviewing the actions of the General Assembly, we presume that a statute comports with constitutional standards. See People v. Janousek, 871 P.2d 1189, 1195 (Colo.1994); People v. Longoria, 862 P.2d 266, 270 (Colo.1993). The party challenging a statute on constitutional grounds bears the burden of establishing the statute’s unconstitutionality beyond a reasonable doubt. See Janousek, 871 P.2d at 1195. Furthermore, “if a challenged statute is capable of different constructions, one of which comports with constitutional standards for validly delegated authority to an administrative agency, we must adopt that construction that accords with constitutional norms.” Lowrie, 761 P.2d at 782.
In the nondelegation context, a reviewing court’s task is to examine the standards and safeguards associated with the operation of the statute. Thus, we first discuss the operation and limits of the Contraband Statute as it is written. We then address the specific concerns about the statute raised by the trial court.
A.
The plain language of the Contraband Statute requires the administrative head of the detention facility to determine whether an item poses or may pose a risk to security prior to categorizing the item as contraband within the meaning of the statute. See § 18-8-204(2)(Z). Thus, a court reviewing the actions of the administrative head must ascertain whether and when he or she determined that an item poses or may pose a security risk.
This is a significant check on the discretionary power of the administrative head because the statute can not be satisfied merely by resort to a post-hoe rational basis analysis. It is not enough that, in retrospect, the administrative head is able to present a rational argument in support of the view that *411the prohibited item poses a security risk. The proper analysis focuses on the actual reasoning employed by the administrative head at the time of his or her decision to prohibit the item because the particular reason behind the prohibition is critical to whether a violation of the prohibition also violates the Contraband Statute.
Additionally, the statute’s requirements allow one charged with violating the statute to challenge the administrative head’s determination by showing that the prohibited item did not or could not pose a threat to the security of the facility. , Furthermore, the fact that the Contraband Statute vests discretion solely in the administrative head to determine what is contraband under the statute also guards against an unreasonable expansion of the power to declare conduct criminal. Once the administrative head makes this determination, all other facility personnel must abide by it, and none may expand it.
Finally, the statute’s requirement of “reasonable notice” is an important safeguard against the unbridled discretion of administrative power. § 18-8-204(2)(£). The provision of reasonable notice, as we construe it in Part IV of this opinion,1 protects against irrational or discriminatory enforcement of the Contraband Statute.
B.
The trial court relied primarily upon two factors in concluding that the Contraband Statute lacked adequate standards and safeguards. First, the trial court found fault with the broad “may pose” language in section 18-8-204(2X0- Second, the trial court was troubled by the fact that whether an item is contraband under the statute may vary from facility to facility.2 We do not find that these considerations negate the standards and safeguards provided by the Contraband Statute.
1.
The trial court found that the “may pose” language was “virtually standardless” because “virtually anything ‘may pose’ a risk.” As support for this conclusion, the trial court relied upon our analysis in People v. Hoehl, 193 Colo. 557, 568 P.2d 484 (1977).
In Hoehl, we considered a constitutional challenge to a child abuse statute which provided that a person commits child abuse when that person places a child in a situation “that may endanger the child’s life or health.” Id. at 560, 568 P.2d at 486 (quoting § 18-6-401(l)(a), 8 C.R.S. (1973)). We noted that the common understanding of “may” was not likely to provide a “fair description of the prohibited conduct, since virtually any conduct directed toward a child has the possibility, however slim, of endangering a child’s life or health.” Id. Thus, we construed the word “may” to mean that there is a “reasonable probability” that the child’s life or health will be endangered. See id. Under this construction, the statute was not unconstitutionally vague.
Similarly, the phrase “may pose a threat” in the Contraband Statute should be construed to mean that there is a reasonable probability that the item1 poses a threat to the security of the facility. Under this construction, the Contraband Statute provides sufficiently clear statutory standards. Therefore, because the statute is capable of a construction “which comports with constitutional standards for validly delegated authority to an administrative agency,” Loimie, 761 P.2d at 782, we conclude that the language of the Contraband Statute does not offend the constitution.
Inherent in this conclusion is the notion that a broader interpretation and application of “may pose a threat” violate the statutory standards described above. In determining whether a particular item may pose a security threat, the administrative head must use the more restrictive concept of “may.” In *412order to comply with the statute and the constitution, the administrative head must determine whether the item poses or has a reasonable probability of posing a threat to the security of the facility.3
2.
The trial court found it significant that the Contraband Statute allows each detention facility in the state to promulgate its own rules regarding what items are contraband under the statute. According to the trial court, the Contraband Statute stands in important contrast to those .statutes that have previously survived challenges based on the nondelegation doctrine because those statutes allowed only, state-wide administrative rules. Thus, the trial court ruled that this characteristic of the Contraband Statute allows unfettered administrative discretion in violation of the nondelegation doctrine. We disagree.
Consistent with its authority to delegate limited powers to local governmental units, see Asphalt Paving Co. v. Board of County Comm’rs, 162 Colo. 254, 259, 425 P.2d 289, 292 (1967), the General Assembly may allow each detention facility to prescribe rules tailored to the individual needs of the facility. As we explained in Lowrie: 761 P.2d at 781 (quoting People v. Willson, 187 Colo. 141, 144, 528 P.2d 1315, 1316 (1974)) (citations omitted). In order to implement such legislative goals, the Contraband Statute allows and obliges the administrator of each detention facility to consider the specific conditions found in that facility in determining which items pose or have a reasonable probability of posing a threat to security.
As long as the General Assembly establishes “a definite framework for the law’s operation,” it may properly delegate the details of rulemaking to an administrative agency to carry out that operation. As our decisions recognize, it will often be impracticable for the General Assembly to fix rigid - standards to guide agency action, particularly in situations involving exercise of police power, without destroying the flexibility necessary to effectuate obvious legislative goals in dealing with complex economic and social problems.
Given that conditions at each facility may vary, with respect to both inmate populations and physical structures, the General Assembly is not. required to create an exclusive list of items that pose a security risk at every facility in the state. The General Assembly need not ignore the reality that some detention facilities may face security risks that do not exist at other facilities. On the contrary, the General Assembly may accommodate such realities in shaping a statute. The constitution allows the General Assembly to delegate limited authority to local governmental units to fashion rules that implement broad statutory objectives, provided that sufficient statutory" or administrative safeguards exist to confine the discretion of the local governmental unit. See Lowrie, 761 P.2d at 781. Therefore, provided that each detention facility complies with the standards found in the Contraband Statute, particularly the notice requirement of section 18-8-204(2)©, the General Assembly’s policy to prohibit the introduction of certain items into detention-facilities is properly implemented.
For the foregoing reasons, we hold that the Contraband Statute is constitutional on its face. The statute provides sufficient statutory standards and safeguards to withstand a challenge based on the nondelegation doctrine.4
IV.
Holmes presents an alternate basis for the trial court’s dismissal of the charge against *413Mm. Holmes argues that the MCDF failed to comply with the Contraband Statute because the MCDF did not supply adequate notice that cigarettes and matches were contraband under the statute. The Contraband Statute requires the administrative head of a detention facility to provide “reasonable notice” of those items that he or she has determined to be contraband under the statute. § 18-8-204(2)®. We agree that the notice provided by the MCDF did not comply with this requirement.
A.
The undisputed facts of this ease establish that visitors are exposed to three large signs upon entering the MCDF.5 The first sign, entitled “Information center, important information — please read, general information,” states in part:
1. No smoking is allowed in the public area of tMs building.
2. The Detention Facility is a tobacco-free facility. No tobacco products or flame producmg devices of any kind are allowed inside the secured perimeter.
A second sign, entitled “Legal/Professional Contact Visits,” states m part:
Legal and professional contact visits include visits from attorneys, social services workers, religious or mental health counselors or bonding company representatives, that take place within the secure perimeter of the detention facility. All professional visitors must adhere to the following gmdelines in addition to the general rules and procedures of the facility.
5. Visitors are not allowed to give the inmate anytMng without prior notification and authorization of the detention staff. Some of the items not allowed include, but are not limited to: tobacco products, magic markers, matches, lighters, food items in-eluding gum, nail files or clippers, pens, paper clips, white out, spiral note books, thumb tacks and keys or any medication.
A third sign, entitled “Visitation Rules,” indicates only that visitors are not allowed to take personal items into the visiting area. Holmes contends that these three signs fail to provide proper notice that cigarettes and matches are contraband within the meaning of the Contraband Statute.
B.
Holmes intermingles his argument about the adequacy of this notice with other issues. First, Holmes contends that the admimstra-tive head of the MCDF failed to determme, prior to the charge against Holmes, that cigarettes or matches pose or may pose a security threat. The parties presented the trial court with conflicting evidence on tMs issue, and the trial court did not resolve this conflict. Because our analysis below concerns the notice of the contraband determination, regardless of when it was made, our ultimate decision does not depend upon the resolution of this factual dispute, and we express no opimon on this dispute. Similarly, because we have not been asked to review the reasonableness of a determination that cigarettes or matches pose or have a reasonable probability of posing a security risk, we offer no view on this issue.
Holmes next asserts that “even if there had been an Administrative Determination, the Mesa County Sheriffs Department never issued proper notice as required by the statute.” Holmes contends that' the signs posted by the MCDF are defective because they do not put the public “on notice that tobacco would cause a felony prosecution or that it would be considered ‘contraband’ under the statute.” The trial court expressed a similar concern in ruling that the signs did not indicate that the introduction of cigarettes or *414matches “would be considered a felony offense.”
Holmes’s position encompasses two arguments, one broader than the other. Holmes appears to assert that the Contraband Statute requires a detention center to provide notice that a violation of its prohibitions is a felony (as opposed to a lesser criminal offense). We disagree with this assertion. Nothing in the Contraband Statute mandates notice that introducing contraband into a facility is a felony, and neither Holmes nor the trial court cites any authority requiring such “felony notice.” The statute does not require a detention facility to notify visitors that the introduction of contraband is a felony.
More broadly, however, Holmes contends that the Contraband Statute requires a detention center to provide notice of those items that are illegal contraband under the statute. To illustrate this position, Holmes explains that:
[NJotice would be most proper if it referred to the statute, and indicated that the Administrative Head of the Detention Facility had determined that a certain list of items pose a threat to the security of the Detention Facility and therefore, would constitute “contraband” under that statute.
Stated differently, Holmes contends that the Contraband Statute demands notice that introducing specific items into the facility is criminal conduct. We agree.
C.
Generally speaking, where the law imposes criminal liability for certain conduct, the scienter element requires “no more than that the person charged with the duty knows what he is doing. It does not mean that, in addition, he must suppose that he is breaking the law.” United States v. Dashney, 937 F.2d 532, 538 (10th Cir.1991), dismissal of post-conviction relief rev’d, 52 F.3d 298 (10th Cir.1995). This general rule is based on the deeply-rooted principle that ignorance of the law or mistake of law is no defense to criminal prosecution. See, e.g., Cheek v. United States, 498 U.S. 192, 199, 111 S.Ct. 604, 112 L.Ed.2d 617 (1991); Lambert v. California, 355 U.S. 225, 228, 78 S.Ct. 240, 2 L.Ed.2d 228 (1957); United States v. Smith, 18 U.S. (5 Wheat.) 153, 182, 5 L.Ed. 57 (1820) (Livingston, J., dissenting). “Based on the notion that the law is definite and lcnowable, the common law presumed that every person knew the law.” Cheek, 498 U.S. at 199, 111 S.Ct. 604 (emphasis supplied).6
The rule that ignorance of the law will not excuse its violation is limited, however, by the constitutional demands of due process. See Lambert, 355 U.S. at 228, 78 S.Ct. 240. “Engrained in our concept of due process is the requirement of notice.” Id. Thus, a law violates due process if it is so vague that its prohibitions are not clearly defined. See Rickstrew v. People, 822 P.2d 505, 506-07 (Colo.1991) (“Due process also requires that a penal statute provide fair warning of the conduct prohibited”); Smith v. Charnes, 728 P.2d 1287, 1290 (Colo.1986) (statute must provide “fair notice of the conduct that has been determined to be unlawful”).
Vague laws offend due process in at least two important ways. First of all, “ ‘because we assume that man is free to steer between lawful and unlawful conduct, we insist that laws give the person of ordinary intelligence a reasonable opportunity to know what is prohibited, so that he may act accordingly.’ ” High Gear & Toke Shop v. Beacom, 689 P.2d 624, 630 (Colo.1984) (quoting Grayned v. City of Rockford, 408 U.S. 104, 108-09, 92 S.Ct. 2294, 33 L.Ed.2d 222 (1972)); see also People v. Buckallew, 848 P.2d 904, 907 (Colo.1993). Secondly, laws must supply explicit standards for those who apply them in order to prevent arbitrary and discriminatory enforcement. See Buckallew, 848 P.2d at 907; People v. Nissen, 650 P.2d 547, 549 (Colo.1982).
*415The due process requirement that a statute clearly define the prohibited conduct is not relaxed simply because the statute delegates certain decisions to an agent or agency. In such a situation, “ ‘[t]he responsibility to promulgate clear and unambiguous standards is on the [agency].’ ” United States v. Trident Seafoods Corp., 60 F.3d 556, 559 (9th Cir.1995). Furthermore, where a violation of an agency regulation subjects a party to criminal sanctions, “a regulation cannot be construed to mean what an agency intended but did not adequately express [and] the [administrative head of the agency] has the responsibility to state with ascertainable certainty what is meant by the standards he has promulgated.” Gates & Fox Co. v. Occupational Safety & Health Review Comm’n, 790 F.2d 154, 156 (D.C.Cir.1986).
Thus, in assessing the propriety of a criminal law, a reviewing court must balance the general rule that ignorance of the law is no defense with the due process requirement of notice. As the Second Circuit explained, in attempting to achieve this balance:
The primary purpose of law, and the criminal law in particular, is to conform conduct to the norms expressed in that law. When there is no knowledge of the law’s provisions, and no reasonable probability that knowledge might be obtained, no useful end is served by prosecuting the “violators.” Since they could not know better, we can hardly expect that they should have been deterred-There is little to recommend incarcerating those who would obey the law if only they knew of its existence.
United States v. Mancuso, 420 F.2d 556, 559 (2d Cir.1970).
Accordingly, our task is three-fold. We must first determine what notice is sufficient to warn visitors to a detention facility that the introduction of an item is a criminal offense pursuant to the Contraband Statute. Next, in order to avoid constitutional conflicts, we must construe the “reasonable notice” provision of the Contraband Statute to require this constitutionally sufficient notice. See generally High Gear & Toke Shop, 689 P.2d at 632 (“If a statute is susceptible to more than one interpretation, it should be construed in a way that will render it constitutional.”). Finally, we must decide whether the notice provided by the MCDF conforms with the statutory notice requirement.
D.
As previously discussed, the undisputed facts of this ease establish the contents of the signs posted within the MCDF. The signs indicate that cigarettes and matches were prohibited within certain areas of the facility. If the administration of MCDF possessed the power to prohibit only those items described in the Contraband Statute, it would be reasonable to assume, simply from the existence of the prohibition, that cigarettes and matches were considered illegal “contraband” within the meaning of the statute. However, there is no such limitation on the administration’s power; the MCDF may prohibit items that do not qualify as “contraband” under the Contraband Statute.7 Thus, one cannot assume that every item prohibited by the MCDF is illegal contraband.8 The fact of the prohibition does not, without more, allow a visitor to determine whether a prohibited item is “contraband” within the meaning of the statute.
For an item to be “contraband” within the meaning of section 18-8-204(2)®, three things are required. The item must be a risk to security, the administrative head must have determined that it is such a risk, and *416reasonable notice must be given that the item has been identified as unlawful “contraband.” A notice that provides only that a particular item is prohibited does not provide notice that an item has been identified as “contraband” within the meaning of this subsection.
Cigarettes and matches may be prohibited for any number of reasons, some of which may be unrelated to security. For example, a detention facility may ban smoking out of a concern for the health of its staff or inmates.9 Cigarettes and matches are illegal contraband under the Contraband Statute only if the administrative head of the MCDF determined that these items posed or reasonably could pose a risk to the security of the facility. Hence, the reason for the prohibition is of paramount importance.
By merely referring to the contents of the signs within the MCDF, one cannot determine if cigarettes and matches have been determined by the administrative head to be security risks, and are, therefore, “contraband.” Cigarettes and matches are included among a long list of prohibited articles, including food items, gum, magic markers and white out. The signs do not indicate which items, if any, are considered by the administrative head of the MCDF to be a security risk to the facility. Thus, even if one had actual knowledge of the precise language of the Contraband Statute, one would not know what items are illegal contraband (the introduction of which may result in criminal prosecution).10
Moreover, the fact that different detention facilities throughout the state may treat cigarettes differently further complicates the issue. For example, Holmes presented evidence at the hearing below that at least thirty-one counties prohibit cigarettes in their detention facilities. According to Holmes, fifteen of these facilities treat cigarettes as contraband within the meaning of the Contraband Statute, while the rest treat the introduction of cigarettes as merely a violation of administrative rules. Without commenting upon the accuracy of this evidence, we note that the Contraband Statute does allow such different treatment of the same item by different facilities. Thus, because the standard of criminality at each facility may vary, a visitor,to a detention facility that prohibits cigarettes can only guess as to whether a violation of the prohibition is criminal conduct. To reiterate, a law offends due process where it “‘either forbids or requires the doing of an act in terms so vague that men of ordinary intelligence must necessarily guess as to its meaning and differ as to its application.’ ” Nissen, 650 P.2d at 550 (quoting Connally v. General Constr. Co., 269 U.S. 385, 391, 46 S.Ct. 126, 70 L.Ed. 322 (1926)) (emphasis supplied).
This scenario is a result of two unique characteristics of the Contraband Statute. First of all, the trial court found that “there is no requirement that the detention facility administrator comply with the State Administrative Procedure Act,” see §§ 24-4-101 to -108, 7 C.R.S. (1997) (the “APA”), and neither party disputes this finding. Where an administrator does not comply with the APA, the public does not enjoy the benefits of the APA’s rule-making, procedures, particularly the methods by which the public may obtain information and submit requests or comments. See § 24-4-103, 7 C.R.S. (1997). *417Thus, the public is not privy to the kind of information, such as the history or purpose of a detention facility rule, that would be available pursuant to the APA’s rule-making process. This fact is significant because this information may allow a visitor to know whether a particular prohibited item is contraband within the meaning of the statute.
The People assert that, “[w]hile compliance with the State Administrative Procedure Act could be seen as one way of giving reasonable notice, there are many other ways in which such notice could be given.” This may be true. The statute’s notice requirement may render it unnecessary for the administrative head of a facility to copy the APA’s rule-making procedures in order to provide reasonable notice. The Contraband Statute requires the facility to provide “reasonable notice ... that such article or thing is contraband.” § 18-8-204(2)© (emphasis supplied). The term “contraband,” in its most general usage, can mean any “goods or merchandise whose importation, exportation, or possession is forbidden.” Webster’s Ninth New Collegiate Dictionary 284 (1989). “Contraband,” however, has a much more limited meaning in the context of the Contraband Statute. “Contraband” is one of the items listed in section 18-8-204(2)(a)-(k). “Contraband” is also defined as an item that the administrative head of the facility has determined to be a risk or probable risk to the security of the facility. § 18-8-204(2)©.
Hence, with respect to “contraband” defined in subsection (2)(Z), the facility must either provide notice that an item has been determined to pose or have a reasonable probability of posing a security risk, or clearly indicate in some other manner that the item is “contraband” as defined by the statute.11 In other words, the notice must be sufficient to allow a visitor to ascertain whether introducing a certain item violates the Contraband Statute. As explained above, the notice provided by the MCDF does not meet this standard.
Secondly, the Contraband Statute requires that, before the introduction of an item is considered criminal conduct, an administrator must determine that the item poses or has a reasonable probability of posing a security threat. Therefore, a visitor’s, or a reviewing court’s, reasonable belief that an item may be a security risk is irrelevant unless the administrative head of the facility has previously determined that the item may be a security risk. Under section 18-8-204(2)©, an item is illegal contraband only after the administrative head has made this determination. Without reasonable notice of this determination, a visitor cannot know whether an item is contraband within the meaning of the statute.
Consequently, the “reasonable notice” provision of the statute cannot be satisfied simply by notice that an item is prohibited. One could not determine from this limited notice whether his or her acts are criminal conduct, even with explicit reference to the Contraband Statute.12 Therefore, the Contraband Statute, in order to comply with due process, requires a more complete notice. At a minimum, the notice must be sufficient to inform a visitor with actual or constructive knowledge of the Contraband Statute that the introduction of the prohibited item is criminal conduct. With respect to the items listed in subsections (2)(a)-(k), the statute itself provides adequate notice that the introduction of the items is unlawful. With respect to an item *418described by subsection (2)(Z), reasonable notice may be accomplished by various methods. For example, the administrative head could promulgate publicly available written rules identifying which items are prohibited in the facility because they have been determined to be a security risk or “contraband” within the meaning of the statute. Reasonable notice also may be accomplished through posted notices, such as signs. The signs may state that a prohibited item either (a) has been determined by the facility to be a security risk, or (b) has been determined to be “contraband” within the meaning of the Contraband Statute. Alternatively, the signs may state that introduction of the item is unlawful or may subject the visitor to criminal prosecution.
As explained above, the notice described by the undisputed facts of this ease indicates only that cigarettes and matches, along with many other items, are prohibited within the facility. These items are not specifically identified as “contraband” under subsections (2)(a)-(k) of the statute. Therefore, because these items are purported to be “contraband” under subsection (2)(l), the notice provided by the MCDF does not conform to the notice requirements of the Contraband Statute. Thus, we affirm the trial court’s dismissal of the case against Holmes.
V.
To summarize, we hold that the Contraband Statute is constitutional on its face. We also hold, however, that the notice provided by the MCDF did not comply with the requirements of the Contraband Statute. Consequently, although we disagree with the reasoning relied upon by the trial court, we affirm its judgment.
MULLARKEY, J., concurs in part and dissents in part; VOLLACK, C.J., and SCOTT, J., join in the concurrence and dissent.. See discussion infra p. 423-424.
. The trial court also expressed concern about the adequacy of the notice of contraband provided by the MCDF, given that each facility may hold a different view of what qualifies as contraband. Because we understand this concern to relate to proper compliance with the statute, rather than the statute’s facial constitutionality, we address this concern in Part IV of this opinion.
.. The trial court did not determine whether the administrative head of MCDF used the proper interpretation of "may pose a threat” in promulgating the prohibition of cigarettes and matches. Indeed, the trial court did not decide whether the administrative head actually determined that cigarettes and matches pose or may pose a security threat. 1 Our ultimate resolution of this case, however, does not depend upon these factual findings.
. Because we conclude that the standards and safeguards found in the Contraband Statute are sufficient to prevent unbridled administrative discretion, we do not address the existence or adequacy of any administrative standards or safeguards. See Cottrell, 636 P.2d at 709-10.
. The People argue that information packets provided at the visitor sign-in also supply notice of the MCDF’s view of contraband. The parties produced conflicting evidence at the hearing below regarding the extent to which visitors actually receive the packets, and the trial court did not resolve this dispute. As the balance of our discussion will make clear, however, the resolution of this dispute is not significant to our decision. Assuming the People’s description of the packets’ contents is correct, the packets provided no more notice than that contained in the signs. In addition, we do not consider the notice provided in the MCDF’s inmate handbook because the handbook is directed to inmates rather than visitors. Thus, our notice analysis is fully served by discussing the adequacy of the signs.
. As early as 1820, Justice Livingston explained, "[N]o one is allowed to allege his ignorance in excuse for any crimes he may commit. Nor is there any hardship in this, for the great body of the community have it in their power to become acquainted with the criminal code under which they live.” Smith, 18 U.S. (5 Wheat.) at 182 (Livingston, J., dissenting).
. Of course, the introduction of prohibited items that do not so qualify would not be a crime under the Contraband Statute.
. In fact, our decision in Lepik precludes this conclusion. See 629 P.2d at 1081. In Lepik, we held that the General Assembly impermissibly delegates its legislative power where it defines illegal contraband as any item "which a person confined in a detention facility is prohibited from obtaining or possessing by statute or a rule, regulation, or order lawfully issued by the administrative head of the detention facility." Id. at 1081 n. 1 (quoting § 18-8-204(2), 8 C.R.S. (1973 & 1978 Supp.)). Because the statute allowed the administrative head to "determine such things as an ice-cream cone to be contraband under that section,” we found that the statute permitted the unbridled exercise of administrative discretion in violation of the non-delegation doctrine. Id. at 1082.
. To illustrate, prior to the hearing below, Holmes presented the trial court a transcript of a certain ruling by Judge Brandenburg in Morgan County, People v. Harold Davis, No. 95M162. In this ruling, Judge Brandenburg faced a claim by the Morgan County jail that it prohibited tobacco products because they were a security risk to the jail. In rejecting this claim. Judge Brandenburg found that the jail's tobacco ban resulted from its concerns about the health risks of tobacco, and was not based on security concerns. For this reason, among others, the judge found that tobacco was not "contraband” within the meaning of the Contraband Statute.
. In this way, the signs within the MCDF differ from the liquor code regulations at issue in Lowrie. See 761 P.2d at 779-80. In that case, we held that the Colorado Liquor Code, combined with the publicly available regulations, provided adequate notice that a violation of the regulations was considered criminal. The Liquor Code provided that a person violating any rule or regulation authorized and adopted pursuant to the Liquor Code was guilty of a misdemeanor. See id. at 783. The regulations themselves made it clear that they were adopted pursuant to the Liquor Code. Thus, one with knowledge of the Liquor Code and the regulations could know that violating the regulations was a crime.
. Of course, the facility need not provide this type of notice with respect to items listed as "contraband” in subsections (2)(a)-(k). The Contraband Statute itself provides notice that the introduction of those specific items is a criminal offense.
. If this type of notice were deemed sufficient, one could be convicted of violating a law the precise terms of which he or she could not know. Such a conviction would be inconsistent with ''ordinary notions of fair play and the settled rules of law.” Buckallew, 848 P.2d at 907; see generally United States v. Hall, 742 F.2d 1153, 1155 (9th Cir.1984) (holding that a regulation resulting in criminal prosecution must either be published in the Federal Register or it must be proven that defendants had actual knowledge of the regulation’s terms). Several jurisdictions supplement due process requirements with a statutory defense, patterned after the Model Penal Code, for those accused of violating an "unavailable law.” See 2 Paul H. Robinson, Criminal Law Defenses § 182 at 381-85 (1984); Model Penal Code § 2.04(3)(a).
