OPINION
Plaintiffs Deena Perlstein and Scott Schneider filed a legal malpractice action against defendants Maurice Wolk and Ross & Hardies. Plaintiffs relied on the limitations period for malpractice actions set forth in section 13— 214.3 of the Code of Civil Procedure, as amended by Public Act 89 — 7 (commonly referred to as the Tort Reform Act). See Pub. Act 89 — 7, eff. March 9, 1995 (amending, inter alia, 735 ILCS 5/13 — 214.3 (West 1994)). Defendants moved to dismiss the complaint, arguing that this court’s decision in Best v. Taylor Machine Works, 179 Ill. 2d 367 (1997), which held Public Act 89 — 7 void in its entirety, rendered plaintiffs’ complaint untimely. The trial court, relying on the void ab initio doctrine, agreed with defendants and dismissed the complaint with prejudice. The appellate court reversed. 349 Ill. App. 3d 161. We allowed defendants’ petition for leave to appeal (177 Ill. 2d R. 315) and now affirm the judgment of the appellate court.
BACKGROUND
I. Limitations and Repose Periods for Attorney Malpractice
Prior to the adoption of Public Act 89 — 7, section *45113 — 214.3 of the Code of Civil Procedure established a two-year limitations period and a six-year repose period for attorney malpractice actions. 735 ILCS 5/13— 214.3(b), (c) (West 1994). Subsection (d) of the statute contained an exception to the repose period:
“When the injury caused by the act or omission does not occur until the death of the person for whom the professional services were rendered, the action may be commenced within 2 years after the date of the person’s death unless letters of office are issued or the person’s will is admitted to probate within that 2 year period, in which case the action must be commenced within the time for filing claims against the estate or a petition contesting the validity of the will of the deceased person, whichever is later, as provided in the Probate Act of 1975.” 735 ILCS 5/13 — 214.3(d) (West 1994).
Public Act 89 — 7, effective March 9, 1995, removed subsection (d), but otherwise left intact the balance of section 13 — 214.3. With the removal of subsection (d), the statute then required — without exception — that all legal malpractice actions be brought within two years from the date the complaining party knew or reasonably should have known of the injury, but in any event, not more than six years after the act or omission occurred. 735 ILCS 5/13 — 214.3(b), (c) (West 1996).
On December 18, 1997, this court entered its decision in Best v. Taylor Machine Works, 179 Ill. 2d 367 (1997). In Best, we held certain “core provisions” of Public Act 89 — 7 violated the separation of powers clause and the prohibition against special legislation. Best, 179 Ill. 2d at 416, 433, 449, 467. Because the core provisions were inseparable from the remainder of Public Act 89 — 7, we concluded that the act must fail in toto. We thus declared Public Act 89 — 7 “void in its entirety.” Best, 179 Ill. 2d at 467. That portion of Public Act 89 — 7 which removed the exception to the statute of repose for attorney malpractice actions set forth in section 13 — 214.3(d) was not one of the core provisions held substantively uncon*452stitutional. Nonetheless, because we held Public Act 89 — 7 void in its entirety, that portion of the act was also rendered invalid.
Against this statutory backdrop, we consider the nature and timing of the malpractice action at issue here.
II. The Malpractice Action
Plaintiffs’ cause of action for legal malpractice stems from defendants’ preparation, on October 23, 1992, of the last will and testament of Lawrence A. Perlstein, Deena Perlstein’s husband. Generally, plaintiffs alleged that defendants negligently prepared the will, thereby preventing the Lawrence A. Perlstein Trust from disbursing $300,000 to Scott Schneider, Deena Perlstein’s son, and causing other damages.
Lawrence Perlstein died on September 23, 1995. On October 16, 1995, the circuit court of Lake County admitted the will to probate and issued letters of office to Deena Perlstein. On January 8, 1996, the attorneys for the trustees of the Lawrence A. Perlstein Trust rendered an opinion that the trustees should not fund the trust on the ground that Lawrence Perlstein had not properly exercised the power of appointment in his will. On January 26, 1996, the trustees notified Deena Perlstein that the trust would not be funded.
At the time Deena Perlstein learned that her late husband’s trust would not be funded, the changes wrought by Public Act 89 — 7 had been on the statute books for almost a year. As noted above, following the passage of Public Act 89 — 7, a two-year limitations period and a six-year repose period applied — without exception — to all attorney malpractice actions. See 735 ILCS 5/13 — 214.30b), (c) (West 1996). According to defendants, the two-year limitations period would have expired, at the latest, on January 26, 1998 (two years from the date Deena Perlstein purportedly had knowledge that the trust would not be funded), and the six-year repose period *453would have expired October 23, 1998 (six years after the date defendants prepared the will). Plaintiffs filed their legal malpractice action in the circuit court of Cook County on January 8, 1998, clearly within the limitations and repose periods.1
Defendants moved to dismiss the complaint with prejudice, arguing that it was time-barred. See 735 ILCS 5/2 — 619(a)(5) (West 2002). According to defendants, because Best declared Public Act 89 — 7 unconstitutional, the act was void ab initio. In effect, Public Act 89 — 7 “never was.” Thus, defendants argued that the exception to the statute of repose set forth in section 13— 214.3(d), which Public Act 89 — 7 sought to remove, “never ceased to have validity.” Under subsection (d), plaintiffs’ cause of action should have been commenced “within the time for filing claims against the estate or a petition contesting the validity of the will of the deceased person, whichever is later.” 735 ILCS 5/13 — 214.3(d) (West 1994). In this case, the later date was the claims-filing date: April 26, 1996. See 755 ILCS 5/18 — 3 (West 1996). In defendants’ view, plaintiffs’ complaint, filed January 8, 1998, was 20 months late.
Plaintiffs countered that the void ah initio doctrine does not govern this case. Plaintiffs relied on Illinois case law holding that where a legislative change in a statute of repose would otherwise instantaneously bar a plaintiff’s cause of action, the plaintiff will be allowed a reasonable period of time in which to file its cause of action. See, e.g., Moore v. Jackson Park Hospital, 95 Ill. 2d 223 (1983); Goodman v. Harbor Market, Ltd., 278 Ill. *454App. 3d 684 (1995). Plaintiffs posited that the result should be no different where the change in the statute of repose results from a judicial decision, rather than legislative action. Thus, plaintiffs argued that their complaint, filed just three weeks following this court’s decision in Best, was filed within a reasonable period of time following the change in the law.
The circuit court acknowledged that the result might he harsh, hut nonetheless applied the void ab initio doctrine and dismissed plaintiffs’ complaint with prejudice. The appellate court reversed, holding that such a result would be fundamentally unfair. The appellate court found that the filing of plaintiffs’ complaint, just three weeks after the Best decision, was within a reasonable period of time after the change in the repose period for malpractice actions and that the complaint was not time-barred. 349 Ill. App. 3d at 169-70. The appellate court remanded the cause for additional proceedings. 349 Ill. App. 3d at 171. This appeal followed.
ANALYSIS
The classic formulation of the void ab initio doctrine, and the one followed in Illinois, is found in the early case of Norton v. Shelby County, 118 U.S. 425, 30 L. Ed. 178, 6 S. Ct. 1121 (1886). There, the Court considered whether an unconstitutional state statute that created a county board could give validity to the acts of the board. The Court answered in the negative, stating in relevant part:
“An unconstitutional act is not a law; it confers no rights; it imposes no duties; it affords no protection; it creates no office; it is, in legal contemplation, as inoperative as though it had never been passed.” Norton, 118 U.S. at 442, 30 L. Ed. at 186, 6 S. Ct. at 1125.
See People v. Gersch, 135 Ill. 2d 384, 399 (1990) (“An unconstitutional law ‘confers no right, imposes no duty and affords no protection. It is *** as though no such law had ever been passed,’ ” quoting People v. Schraeberg, *455347 Ill. 392, 394 (1932), in turn citing Board of Highway Commissioners v. City of Bloomington, 253 Ill. 164, 176 (1911), in turn citing Norton, 118 U.S. 425, 30 L. Ed. 178, 6 S. Ct. 1121). Thus, under the Norton rule, an unconstitutional statute is void ab initio, i.e., void “from the beginning.” See Black’s Law Dictionary 1604 (8th ed. 2004).
Defendants argue that our case law mandates strict application of the void ab initio doctrine in both civil and criminal cases, irrespective of the consequences, and that the appellate court erred in failing to apply the doctrine in this civil case. Plaintiffs argue that the better approach takes into account the equities of a case, and that under the equities here, their complaint should be allowed to proceed. We consider these arguments in turn.
I. Strict Application of the Void Ab Initio Doctrine
In support of their argument for strict application of the void ab initio doctrine, defendants rely principally on the Gersch opinion. In Gersch, we considered whether our earlier decision in People ex rel. Daley v. Joyce, 126 Ill. 2d 209 (1988), should apply retroactively to Gersch’s case. In Joyce, we held that section 115 — 1 of the Code of Criminal Procedure of 1963 (Ill. Rev. Stat. 1987, ch. 38, par. 115 — 1), which granted the State a right to demand a jury in certain criminal trials, was unconstitutional. Gersch argued in his direct appeal that the State’s jury demand in his case violated his constitutional right to a bench trial. In holding that Joyce would apply retroactively to Gersch’s case, we stated:
“A constitutionally repugnant enactment suddenly cuts off rights that are guaranteed to every citizen (Ill. Const. 1970, art. I, § 1 (‘All men *** have certain inherent and inalienable rights’)), and instantaneously perverts the duties owed to those citizens. To hold that a judicial decision that declares a statute unconstitutional is not retroactive would forever prevent those injured under the unconstitutional legislative act from receiving a remedy for the deprivation *456of a guaranteed right. This would clearly offend all sense of due process under both the Federal and State Constitutions. [Citations.] Along with these considerations, we note that this court has expressly held that a defendant cannot be prosecuted under an unconstitutional act.” Gersch, 135 Ill. 2d at 397-98.
We concluded that “where a statute is violative of constitutional guarantees, we have a duty not only to declare such a legislative act void, but also to correct the wrongs wrought through such an act by holding our decision retroactive.” Gersch, 135 Ill. 2d at 399. To correct the wrong wrought in Gersch’s case, we reversed his conviction and remanded the cause for a new trial. Gersch, 135 Ill. 2d at 401-02.
Unlike the statute at issue in Gersch, the portion of Public Act 89 — 7 that removed section 13 — 214.3(d) from the attorney malpractice statute of limitations did not “suddenly cut off rights guaranteed to every citizen” or even to these particular defendants. Attorneys in this state possess no constitutional guarantee of a particular limitations or repose period for malpractice actions. Thus, the change made in the repose period by Public Act 89 — 7 did not perpetrate a “wrong” against defendants requiring correction. Indeed, the amendment to the repose period was rendered invalid simply because it could not be severed from the balance of Public Act 89 — 7, and not because it contravened any constitutional principle. In other words, the invalidity of the amendment to section 13 — 214.3 was simply “collateral damage” from the force of this court’s declaration in Best that the core provisions of Public Act 89 — 7 were substantively unconstitutional. Under these circumstances, and in contrast to the Gersch case, failing to adhere strictly to void ab initio principles would not deprive defendants of a remedy for the deprivation of a constitutional right because no such right is implicated.
Notwithstanding these important factual distinctions *457between Gersch and the present case, defendants argue that the void ab initio doctrine must be strictly applied in this civil case just as it was in Gersch. Defendants note that Gersch, itself, contains citation to civil cases from this court applying the doctrine. E.g., Gersch, 135 Ill. 2d at 390, citing Van Driel Drug Store, Inc. v. Mahin, 47 Ill. 2d 378 (1970). The civil cases cited in the Gersch opinion establish, at most, that the void ab initio doctrine can be applied to a civil case; they do not establish that the doctrine should be applied to civil cases generally, or to this civil case in particular. Moreover, the Gersch opinion left open the issue of whether application of the void ab initio doctrine is always appropriate in cases outside the area of criminal prosecutions:
“We must note, however, that courts have been struggling with the potentially harsh results of the ab initio doctrine, particularly where law enforcement officials have relied in good faith on the validity of a statute [citations], or where the invalidation of rules of criminal procedure would allow otherwise guilty criminals to win their freedom [citation]. Attempting to avoid these problems, courts have attempted to temper the ab initio doctrine’s harsh results *** to minimize unfairness. [Citation.] However, scholars have noted that in the area of criminal prosecution, the ab initio principle is especially appropriate.” (Emphasis added.) Gersch, 135 Ill. 2d at 399-400.
We are, therefore, reluctant to extend the reach of Gersch beyond cases involving criminal prosecutions.
Defendants also cite our more recent decisions in Petersen v. Wallach, 198 Ill. 2d 439 (2002), and Jorgensen v. Blagojevich, 211 Ill. 2d 286 (2004). Defendants argue that Petersen and Jorgensen establish that the void ab initio doctrine must be applied in this case despite the possibility of harsh results. We disagree.
As defendants note, Petersen and the present case involve the same statute. At issue in Petersen, however, was the proper construction of section 13 — 214.3(d). Petersen states: “The sole issue presented by this appeal is *458whether the exception to the six-year statute of repose for attorney malpractice actions *** applies only in cases where the assets of the deceased pass by way of the Probate Act ***.” Petersen, 198 Ill. 2d at 441. In the course of deciding that issue, we quoted with favor the following passage from an earlier case:
“ ‘ “Where the words employed in a legislative enactment are free from ambiguity or doubt, they must he given effect by the courts even though the consequences may he harsh, unjust, absurd or unwise. [Citations.] Such consequences can he avoided only by a change of the law, not by judicial construction.” ’ ” Petersen, 198 Ill. 2d at 447, quoting County of Knox ex rel. Masterson v. The Highlands, L.L.C., 188 Ill. 2d 546, 557 (1999), quoting People ex rel. Pauling v. Misevic, 32 Ill. 2d 11, 15 (1964).
Whether, under our rules of statutory construction, an absurd or unjust result should impact our reading and application of a clearly worded statute is unrelated to the issue of whether the void ah initio doctrine should be applied in a given case.
Defendants are correct that, in a footnote, the Petersen opinion implicitly applies the void ah initio doctrine. Petersen, 198 Ill. 2d at 443 n.l. We note, however, that neither the plaintiff nor the defendant attorney argued that the void ah initio doctrine should not apply in that case. Consequently, we were not asked to consider whether it is ever appropriate to temper the doctrine’s harsh results. Any harsh results in Petersen resulted from our construction of the statute, not from application of the void ah initio doctrine. Defendants’ reliance on Petersen is misplaced.
The Jorgensen case is also distinguishable from the present dispute. At issue in Jorgensen was “whether the General Assembly and the Governor violated the Illinois Constitution when they attempted to eliminate the cost-of-living adjustments [COLAs] to judicial salaries provided by law for the 2003 and 2004 fiscal years.” Jorgensen, 211 Ill. 2d at 287. We answered that question in *459the affirmative and refused to “suspend” constitutional requirements for economic reasons, namely, the impact on the state’s budget. Jorgensen, 211 Ill. 2d at 316. In the course of our decision, we held Public Act 92 — 607, which suspended the 2003 COLA, constitutionally infirm and void ab initio. Jorgensen, 211 Ill. 2d at 309. Here, plaintiffs do not request that we “suspend” constitutional requirements by enforcing an unconstitutional statute. Rather, plaintiffs ask that we consider the equities of this case and allow their complaint to proceed. Jorgensen does not aid in our resolution of this issue.
We acknowledge that defendants’ position — advocating strict application of the void ab initio doctrine — has a certain surface appeal, creating as it would a bright-line rule which could be applied with relative ease. Defendants’ position, however, unduly discounts the real-life consequences flowing from a statutory enactment. When the General Assembly enacts legislation such as Public Act 89 — 7, that legislation is presumptively valid. See, e.g., In re Marriage of Bates, 212 Ill. 2d 489, 509 (2004) (“Statutes are presumed constitutional”); Beaubien v. Ryan, 198 Ill. 2d 294, 298 (2001) (statutory enactments are “cloaked with the presumption of validity”). Individuals, including plaintiffs here, “are entitled to rely on State statutes when ‘making decisions and in shaping their conduct.’ ” Board of Commissioners of the Wood Dale Public Library District v. County of Du Page, 103 Ill. 2d 422, 429 (1984), quoting Lemon v. Kurtzman, 411 U.S. 192, 199, 36 L. Ed. 2d 151, 160, 93 S. Ct. 1463, 1468 (1973). See also Adukia v. Finney, 315 Ill. App. 3d 766, 770 (2000) (recognizing, in a post-Resi case, that “a party should not be penalized for his good-faith reliance on existing law”). Individuals are not required or empowered to determine whether the law is constitutional; that duty belongs to the judiciary. Gersch, 135 Ill. 2d at 398-99. Strict application of the void ab initio doctrine fails to *460take into account these realities, creating a “Catch-22.” Individuals are entitled to rely on a legislative enactment, presuming it is valid, but must suffer the consequences of doing so should this court later hold that law unconstitutional.
Although defendants note that courts in other jurisdictions strictly apply the void ab initio doctrine (e.g., Spanish Cove Sanitation, Inc. v. Louisville-Jefferson County Metropolitan Sewer District, 72 S.W.3d 918, 921 (Ky. 2002); McGuire v. C&L Restaurant Inc., 346 N.W2d 605, 614 (Minn. 1984)), our research reveals that courts do not do so universally. As discussed below, courts in other jurisdictions frequently consider the equities of a case and will take steps to ameliorate the harsh results from the doctrine’s strict application. Whether Illinois should adopt a similar approach is the issue we now consider.
II. An Equitable Approach
As noted above, Illinois’ void ab initio doctrine has its roots in the early case of Norton v. Shelby County, 118 U.S. 425, 30 L. Ed. 178, 6 S. Ct. 1121 (1886). Under the Norton rule, the invalid statute is “eliminated entirely from the consideration of a case.” O. Field, The Effect of an Unconstitutional Statute 3 (1935). No weight is given to the fact that the statute was enacted by the legislature, approved by the Governor, and relied upon by the people prior to it being declared invalid by a court. O. Field, The Effect of an Unconstitutional Statute 3 (1935). Under this approach, some courts have gone so far as to rule that “an unconstitutional statute could not protect an officer who executed it or a person who acted in reliance upon it for personal liability for the consequences of their actions.” 1 N. Singer, Sutherland on Statutory Construction § 2:7, at 47 (6th ed. 2002).
The failure of the Norton rule to consider the reliance interests of individuals was described early on by the New Jersey Supreme Court as follows:
*461“The vice of the doctrine of Norton v. Shelby County *** is that it fails to recognize the right of the citizen, which is to accept the law as it is written, and not to be required to determine its validity. The latter is no more the function of the citizen than is the making of the law. *** To require the citizen to determine for himself, at his peril, to what extent, if at all, the legislature has overstepped the boundaries defined by the constitution *** would be to place upon him an intolerable burden.” Lang v. Mayor & Chief of Police, 74 N.J.L. 455, 459 (1907).
The United States Supreme Court has also recognized that inequities can result from strict application of the Norton rule. See Chicot County Drainage District v. Baxter State Bank, 308 U.S. 371, 84 L. Ed. 329, 60 S. Ct. 317 (1940); Lemon v. Kurtzman, 411 U.S. 192, 36 L. Ed. 2d 151, 93 S. Ct. 1463 (1973). In Chicot County, Chief Justice Hughes, writing for a unanimous Court, noted that “broad statements,” such as those in Norton, “as to the effect of a determination of unconstitutionality must be taken with qualifications.” Chicot County, 308 U.S. at 374, 84 L. Ed. at 332, 60 S. Ct. at 318. The Court explained that “[t]he actual existence of a statute, prior to such a determination, is an operative fact and may have consequences which cannot justly be ignored. The past cannot always be erased by a new judicial declaration.” Chicot County, 308 U.S. at 374, 84 L. Ed. at 333, 60 S. Ct. at 318.
The Court again took up the shortcomings of the Norton rule in the Lemon case. There, Chief Justice Burger (in a plurality opinion) acknowledged the difficulty in attempting to reconcile “the constitutional interests reflected in a new rule of law with reliance interests founded upon the old.” Lemon, 411 U.S. at 198, 36 L. Ed. 2d at 160, 93 S. Ct. at 1468. Chief Justice Burger recognized that although the logic of Norton may have been appealing “in the abstract,” “statutory or even judge-made rules of law are hard facts on which people must rely in making decisions and in shaping their *462conduct.” Lemon, 411 U.S. at 199, 36 L. Ed. 2d at 160, 93 S. Ct. at 1468.
Numerous courts are in agreement that Norton represents the old rule as to the effect of an unconstitutional statute. See, e.g., Ryan v. County of Du Page, 45 F.3d 1090, 1094 (7th Cir. 1995) (acknowledging that the “old doctrine,” under Norton, pursuant to which unconstitutional statutes are void ab initio “has been abandoned”); Trucke v. Erlemeier, 657 F. Supp. 1382, 1391 (N.D. Iowa 1987) (observing that the United States Supreme Court abandoned the Norton rationale and suggesting that “if Norton and its progeny were decided today, the outcome would be different”); United States v. DePoli, 628 F.2d 779, 782 (2d Cir. 1980) (recognizing that the Norton view, under which an unconstitutional law is treated as having had no effects whatsoever from the date of its enactment, has been replaced by a more “realistic approach”); W.R. Grace & Co. v. Department of Revenue, 137 Wash. 2d 580, 594 & n.10, 973 E2d 1011, 1017 & n.10 (1999) (rejecting parties’ reliance on the now-abandoned void ab initio doctrine and referring to Norton as “antiquated Supreme Court authority”); American Manufacturers Mutual Insurance Co. v. Ingram, 301 N.C. 138, 147-50, 271 S.E.2d 46, 51-52 (1980) (stating that, “[djepending on the circumstances, courts have employed other rules which avoid the hard and fast consequences of the rule enunciated in Norton,” and that North Carolina has retreated from that rule); Wagshal v. Selig, 403 A.2d 338, 341-42 (D.C. App. 1979) (discussing the decline of the “once-popular ‘void ab initio’ rule” and following the “recent trend in adopting a test of reasonableness and good faith in determining the effect which the judicial invalidation of a statute or regulation should have on the rights and obligations of the parties who have taken action pursuant to an invalid provision”); Perkins v. Eskridge, 278 Md. 619, 627-37, 366 *463A.2d 21, 27-32 (1976) (discussing the development of the void ab initio rule and other approaches used when determining the status of a statute declared unconstitutional, and joining those jurisdictions which have refused to apply the void ab initio rule in all situations), overruled on other grounds by Parrott v. State, 301 Md. 411, 483 A.2d 68 (1984).
Further, at least one legal scholar has recognized that, in light of the injustice and inconvenience which may follow when the void ab initio doctrine is strictly applied, the “modern trend” is away from void ab initio toward a more equitable and realistic approach that is tempered by considerations of reasonableness and good-faith reliance on the purportedly valid statute. 1 N. Singer, Sutherland on Statutory Construction § 2:7, at 47-49 (6th ed. 2002). See also E. Plave, Note, The Phenomenon of Antique Laws: Can a State Revive Old Abortion Laws in a New Era?, 58 Geo. Wash. L. Rev. 111 (1989) (discussing the development and decline of the void ab initio doctrine and alternative approaches); O. Field, The Effect of an Unconstitutional Statute 91 (1935) (suggesting that Norton’s dogmatic statement is not true, i.e., “Courts have held that unconstitutional statutes have imposed duties, have granted rights, have created offices, and have some operative effect”).
The circumstances under which state courts have found it appropriate to reject the void ab initio doctrine, in favor of a more realistic and equitable approach, are varied. For example, in Downs v. Jacobs, 272 A.2d 706 (Del. 1970), the Delaware Supreme Court declined to apply the Norton rationale in a landlord and tenant dispute involving a distraint for unpaid rent:
“The Delaware Landlord Distress Law has never been adjudged unconstitutional. Therefore, it is clothed by a presumption of constitutionality. [Citations.] The [defendants] in the instant case were entitled to rely upon that presumption of constitutionality and validity, and to act *464reasonably and in good faith under the provisions of the Law as it then existed. Citizens and public officials have a right to accept the law as it is written until it is repealed or judicially condemned. They are not required to speculate upon the validity of a statute or to act under it at their peril. Until legislatively or judicially excised, a statute is an operative fact. Courts presume every legislative act constitutional and indulge every intendment in favor of validity. No penalty may be visited upon citizens for doing likewise.” Downs, 272 A.2d at 707.
More recently, in Dutch Point Credit Union, Inc. v. Caron Auto Works, Inc., 36 Conn. App. 123, 648 A.2d 882 (1994), a Connecticut appeals court declared a statute unconstitutional on due process grounds and then considered the effect of its ruling on the plaintiffs claim for damages. The plaintiff held a lien on a motor vehicle which the defendant repair facility had sold, pursuant to the invalid statute, without notifying the plaintiff. The Connecticut court declined to award damages. The court observed that, in response to the Supreme Court’s statements in Chicot County and Lemon,
“a number of jurisdictions have adopted tests of reasonableness and good faith to determine the consequences of conduct undertaken pursuant to a statute subsequently deemed invalid. [Citations.] Those jurisdictions have concluded that, generally, it would be an injustice to penalize á person for actions taken under a statute that was valid at the time of the conduct. We join those jurisdictions, and recognize that citizens have the right to accept statutory law as written until it is repealed or invalidated; citizens are not required to speculate on the constitutionality of a statute before acting under it. We, therefore, hold that citizens will not face personal liability for acting reasonably and in good faith reliance on the provisions of a statute that is later declared unconstitutional.” Dutch Point, 36 Conn. App. at 134-35, 648 A.2d at 888.
Of particular relevance here is a Missouri case, State ex rel. Cardinal Glennon Memorial Hospital for Children *465 v. Gaertner, 583 S.W.2d 107, 118 (Mo. 1979). There, the Missouri Supreme Court held that medical malpractice claims, timely submitted under a statute later held unconstitutional, were not time-barred under the void ab initio doctrine. The statute at issue required that all medical malpractice claims be submitted first to a review board which would make a nonbinding recommendation on liability and damages. Submission of the claim to the board, with appropriate notice to the defendants, tolled the running of the limitations period for malpractice claims during the time required for the board to consider the matter. The Missouri Supreme Court held the statute invalid in that it imposed a procedure as a precondition to access to the courts, in violation of the Missouri constitution. Cardinal Glennon, 583 S.W.2d at 110.
A month after Cardinal Glennon was decided, the Missouri Supreme Court, in a supplemental opinion, addressed the status of the numerous claims that were pending before the review board. Cardinal Glennon, 583 S.W.2d at 118. The court noted that the claimants “undoubtedly relied on the protection afforded them by the tolling provision.” Cardinal Glennon, 583 S.W.2d at 118. Citing Norton and other case law, the court acknowledged that, in the past, an unconstitutional statute conferred no rights from the date the statute was enacted, and not merely from the date of the decision holding it invalid. The court concluded, however, that the “modern view” rejects this rule “to the extent that it causes injustice to persons who have acted in good faith and reasonable reliance upon a statute later held unconstitutional.” Cardinal Glennon, 583 S.W.2d at 118. The court observed that, if the tolling provisions are viewed as retroactively unconstitutional, those claimants who reasonably and in good faith relied upon the statute to protect their right to submit their claims to the courts would suffer a “manifest injustice.” Cardinal Glennon, *466583 S.W.2d at 118. Accordingly, the court ordered that the statute of limitations would be tolled for claims submitted to the review board between the effective date of the statute and the effective date of the court’s declaration of invalidity — an approximately two-year period. Cardinal Glennon, 583 S.W.2d at 118.2
Although this court is not bound by trends in the law occurring outside our jurisdiction, this court has considered whether Illinois law is consistent with our sister states and, where appropriate, has adopted the views of other jurisdictions. See, e.g., American Family Mutual Insurance Co. v. Savickas, 193 Ill. 2d 378, 385-86 (2000) (overruling, in part, a prior decision of this court because “the modern trend” in favor of according estoppel effect to criminal convictions was correct); River Park, Inc. v. City of Highland Park, 184 Ill. 2d 290, 311 (1998) (noting that our adoption of the transactional test to determine whether identity of causes of action exists for purposes of res judicata is consistent with “the trend of decisions in other jurisdictions”); Wilson v. Clark, 84 Ill. 2d 186, 195 (1981) (explaining that “[tjhis court’s following of Federal Rules 703 and 705 comports with the modern trend liberalizing certain trial procedures”). Upon careful review, we are persuaded by the foregoing authorities that this court should adopt a more moderate approach when determining the effect of a declaration by this court that a statute is unconstitutional.
We do not, however, abandon the Norton rule. In cases such as Gersch, where a defendant’s constitutionally guaranteed rights are in need of vindication, strict application of the void ab initio doctrine is appropriate. In other cases, however, where no such rights are at *467stake, other equitable and practical factors are appropriate for consideration by this court. The issue is not so much a matter of applying or not applying the void ab initio doctrine, as it is determining whether a particular set of circumstances justifies a court’s exercise of its equitable powers to ameliorate the doctrine’s sometimes harsh results. Consideration of the circumstances in this case leads us to conclude that plaintiffs’ complaint should be allowed to proceed.
III. The Present Dispute
At the time Deena Perlstein learned that her husband’s trust would not be funded, Public Act 89 — 7 had been in effect for almost a year. Under section 13 — 214.3, as amended by Public Act 89 — 7, Deena Perlstein and her son were required to file their malpractice action within two years from the date they knew or reasonably should have known of the injury but, in any event, not more than six years after the act or omission occurred. 735 ILCS 5/13 — 214.3(b), (c) (West 1996). Before either period expired, this court decided Best, holding Public Act 89 — 7 void in its entirety. Best, 179 Ill. 2d at 467. Plaintiffs filed their complaint three weeks after Best was decided, but still within the limitations and repose periods.
Defendants argue that these circumstances do not justify a departure from the void ab initio doctrine. In other words, the equities are not in plaintiffs’ favor. Defendants note that nothing in Public Act 89 — 7 “compelled” plaintiffs to delay in filing their claim. Defendants also note that Public Act 89 — 7 and the immediate constitutional challenges to the act received “considerable public attention.” Defendants thus question plaintiffs’ reliance on a “new, controversial statute.”
We agree with defendants that nothing in Public Act 89 — 7 “compelled” plaintiffs to wait almost two years before filing their complaint. Numerous legitimate *468reasons, however, may exist for not filing sooner. We will not assume that plaintiffs were less than diligent in pursuing their claim or otherwise acted unreasonably simply because they did not file their complaint within the first three months of what was then a two-year limitations period.
Furthermore, plaintiffs were entitled to rely on the two-year limitations period and six-year repose period because Public Act 89 — 7 was presumptively valid. See Wood Dale Public Library District, 103 Ill. 2d at 429. From the date of its inception, to the date of this court’s decision invalidating it, Public Act 89 — 7 was, for all intents and purposes, “the law.” The changes wrought by Public Act 89 — 7 were “hard facts” on which individuals, including plaintiffs, necessarily relied “in making decisions and in shaping their conduct.” Lemon, 411 U.S. at 199, 36 L. Ed. 2d at 160, 93 S. Ct. at 1468.
Whether Public Act 89 — 7 was “controversial,” as defendants maintain, is inapposite. This court, when it considered the challenges to Public Act 89 — 7 raised in Best, began its analysis with the presumption that the act was constitutional. Best, 179 Ill. 2d at 377. That presumption was not lessened or compromised simply because the legislation — or more correctly, certain key provisions of the legislation — might be described as “controversial.” Similarly, the fact that constitutional challenges to Public Act 89 — 7 received “considerable public attention” did not require plaintiffs to anticipate with certainty that the change to the repose period for legal malpractice actions — which was not itself under review — would fall, along with the key provisions of the act, ultimately barring their complaint. Indeed, in light of the express severability provision contained in Public Act 89 — 7 (Pub. Act 89 — 7, § 990, eff. March 9, 1995), plaintiffs should not be faulted for relying on the continuing validity of section 13 — 214.3(d), notwithstanding the *469fact that constitutional challenges had been made to other sections of the act.
Our case law firmly establishes that a change in the law shortening a limitations period will not be applied retroactively so as to terminate a cause of action unless the claimant has had a reasonable period of time after the effective date of the change in which to file an action. Guzman v. C.R. Epperson Construction, Inc., 196 Ill. 2d 391, 402 (2001); Mega v. Holy Cross Hospital, 111 Ill. 2d 416, 420 (1986); Arnold Engineering, Inc. v. Industrial Comm’n, 72 Ill. 2d 161, 166 (1978); Meegan v. Village of Tinley Park, 52 Ill. 2d 354, 359 (1972). The reasonable-time rule also applies to a change in the law affecting a period of repose. M.E.H. v. L.H., 177 Ill. 2d 207, 216-17 (1997); Mega, 111 Ill. 2d at 420-22. Underlying the reasonable-time rule are “basic concepts of justice, fairness and equity.” Phillips v. Johnson, 231 Ill. App. 3d 890, 895 (1992).
Although this judicial “safety valve” was created in response to changes in the law resulting from legislative action (People v. Bates, 124 Ill. 2d 81, 87 (1988)), no reasoned basis exists for distinguishing between that situation and the one present here where a change in the law results from a judicial decision. As our appellate court observed: “A change in a statute of repose by either legislative enactment or judicial decision yields the same result.” 349 Ill. App. 3d at 169. Moreover, this court has held that the reasonable-time rule will apply “even in those instances in which the legislature has expressed an intent that the limitations period be applied retroactively.” Guzman, 196 Ill. 2d at 402; accord Bates, 124 Ill. 2d at 87. If the rule applies in those instances, then it should also apply where a change in a limitation or repose period results from one of this court’s own decisions. See Adukia, 315 Ill. App. 3d at 770-71 (holding that defendant had a reasonable time after Best in which to file her contribution action).
*470In this case, by virtue of our decision in Best, no period of time remained in which plaintiffs could file their complaint. Their complaint was instantaneously barred when the prior version of section 13 — 214.3 became operative again. Accordingly, plaintiffs should have been allowed a reasonable period of time in which to file their complaint. No fixed rule exists for determining what constitutes a reasonable time following a change in the law in which a plaintiff must initiate litigation. Rather, our court has adopted a case-by-case approach. M.E.H., 177 Ill. 2d at 218-19. Using the unexpired portion of the limitations or repose period on which a plaintiff relied to define what constitutes a reasonable time for bringing suit may be appropriate where the unexpired portion is relatively short. M.E.H., 177 Ill. 2d at 218. Here, by defendants’ calculations, 5V2 weeks of the two-year limitations period and approximately 10 months of the repose period remained at the time Best was decided. Plaintiffs filed their complaint within three weeks of Best. Under these circumstances, we hold that plaintiffs filed their complaint within a reasonable period of time following the change in the law, and that their complaint is not time-barred.
Allowing plaintiffs’ complaint to proceed does not mean, as defendants suggest, that this court is enforcing an unconstitutional statute. Plaintiffs’ complaint will proceed not because the amended version of section 13— 214.3 governs this dispute, but because the circumstances here justify the exercise of our equitable powers to ameliorate the harsh results from this court’s declaration that Public Act 89 — 7 is void.
Allowing plaintiffs’ complaint to proceed also does not mean, as defendants argue, that courts in future cases may now effectively ignore the void ab initio doctrine and, with it, the Illinois Constitution. We reiterate that our decision in this case does not signal an *471abandonment of the void ab initio doctrine. Public Act 89 — 7 remains void in its entirety. Our decision simply recognizes that although this court may declare a statute unconstitutional, it cannot erase the fact of the statute’s existence. See Chicot County, 308 U.S. at 374, 84 L. Ed. at 333, 60 S. Ct. at 318 (“The past cannot always be erased by a new judicial declaration”); L. Tribe, American Constitutional Law § 3 — 3, at 28 (2d ed. 1988) (“ ‘the courts have no real power to repeal or abolish a statute, and ... notwithstanding a decision holding it unconstitutional a statute continues to remain on the statute books’ ”), quoting 39 Ill. Att’y Gen. Op. 22 (1937). Finally, our decision in this case does not require courts in other cases involving different litigants, different statutes, and different circumstances, to rule in favor of the party claiming reliance on a statute later held unconstitutional. Each case must be judged on its own merits.
CONCLUSION
For the reasons discussed above, we affirm the judgment of the appellate court reversing the judgment of the circuit court and remanding the cause to the circuit court for further proceedings.
Affirmed.
