delivered the opinion of the court:
In November 1999, the trial court dismissed defendant’s second postconviction petition, finding it frivolous and patently without merit. 725 ILCS 5/122 — 2.1(a)(2) (West 1998). Defendant appeals, arguing that section 122 — 2.1 of the Post-Conviction Hearing Act (Act) (725 ILCS 5/122 — 2.1 (West 1998)) violates the single subject rule of the Illinois Constitution (Ill. Const. 1970, art. iy § 8(d)). We affirm.
I. BACKGROUND
In October 1997, a Champaign County jury convicted defendant, Calvin L. Dorris, of first degree murder (720 ILCS 5/9 — 1(a)(1) (West 1996)), and in November 1997, the trial court sentenced defendаnt to 50 years in prison. Defendant appealed to this court and, in June 1999, although remanding the cause for correction of errors related to defendant’s sentence, we otherwise affirmed defendant’s conviction. People v. Dorris, No. 4 — 97—1102, slip order at 3-4 (June 8, 1999) (unpublished order under Supreme Court Rule 23).
In March 1999, during pendency of his direct appeal, defendant filed a pro se petition for postconviction relief. 725 ILCS 5/122 — 1 (West 1998). In May 1999, the trial court dismissed defendant’s petition as frivolous and patently without merit. 725 ILCS 5/122 — 2.1(a)(2) (West 1998). Defendant appealed and his counsel filed a motion to withdraw pursuant to Anders v. California,
In October 1999, while the appeal of his first postconviction petition was pending, defendant filed a second petition for postconviction relief alleging violations of his fifth, sixth, and fourteenth amendment rights (U.S. Const., amends. V, VI, XIV) based on the trial court’s denial of a motion to suppress, its refusal to give a second-degree murder jury instruction, references to the victim’s race during trial, and ineffective assistance of appellate counsel for failing to raise the issues on direct appeal. In November 1999, the trial court dismissed defendant’s second petition as frivolous and patently without merit, noting the proceedings surrounding defendant’s first postconviction petition were “not deficient in some fundamental way,” and further, defendant “failed to demonstrate any basis to warrant the [cjourt’s consideration of his second postconviction petition.” This appeal followed.
II. ANALYSIS
Dеfendant argues section 122 — 2.1 of the Act (725 ILCS 5/122— 2.1 (West 1998)), which empowers trial courts, prior to appointing counsel, to dismiss those postconviction petitions that are “frivolous” or “patently without merit,” is void ab initio bеcause the public act creating the first-stage dismissal, Public Act 83 — 942 (Pub. Act 83— 942, eff. November 23, 1983 (1983 Ill. Laws 6200)), violates the single subject rule of the Illinois Constitution of 1970. Specifically, defendant argues Public Act 83 — 942 violates the Illinois Constitution’s single subject rule because the act, on its face, clearly embraces more than the single subject of the “criminal justice system.” Arangold Corp. v. Zehnder,
A. Forfeiture
Preliminarily, although failing to argue the unconstitutionality of Public Act 83 — 942 in his second postconviction petition, defendant asserts he may nonetheless challengе the statute’s constitutionality at any time under People v. Wooters,
“The [Act] contemplates the filing of only one post[ ]conviction petition, although successive petitions may be allowed where the рroceedings on the initial petition were deficient in some fundamental way. [Citation.] The Act provides *** any claim of a substantial denial of constitutional rights not raised in the original or [in] an amended petitiоn is [forfeited]. 725 ILCS 5/122 — 3 (West 1996); [citation].” (Emphasis added.) People v. Erickson,183 Ill. 2d 213 , 222-23,700 N.E.2d 1027 , 1032 (1998).
Despite these procedural bars, a defendant may properly argue in a subsequent postconviction petition ineffective аssistance of appellate counsel, where appellate counsel also represented defendant during his initial postconviction petition. Erickson,
Additionally, defendant’s claim is barred by res judicata. Because the trial court dismissed defendant’s first postconviction petition without an evidentiary hearing, finding it was frivolous and patently without merit, defendant could have аlleged Public Act 83— 942 violated the single subject rule during his appeal. He did not do so. A ruling on a postconviction petition is res judicata with respect to all claims actually raised or those that could hаve been raised in the initial postconviction proceedings. Erickson,
B. The Text of Public Act 83 — 942
Defendant argues the texts of the individual sections contained within Public Act 83 — 942 do not relate to the single subjеct of the “criminal justice system.” Our conclusion defendant has forfeited his right to raise a single subject rule challenge notwithstanding, our review of the act’s provisions convinces us Public Act 83 — 942 does not violate thе single subject rule. Accord People v. Roberts,
Public Act 83 — 942 contains five sections amending five different statutes. Sections 1 and 2 amend the Criminal Code of 1961 (Criminal Code) (Ill. Rev. Stat. 1981 & 1982 Supp., ch. 38, pars. 1 — 1 through 43 — 2), the Code of Criminal Procedure of 1963 (Code) (Ill. Rev. Stat. 1981 & 1982 Supp., ch. 38, pars. 100 — 1 through 126 — 1), and the Unified Code of Corrections (Unified Code) (Ill. Rev. Stat. 1981 & 1982 Supp., ch. 38, pars. 1001 — 1—2 through 1008 — 6—1), respectively (Pub. Act 83 — 942, §§ 1, 2, eff. November 23, 1983 (
Section 1 expands the definition of “public official” in seсtion 12 — 9 of the Criminal Code, which makes it a crime to threaten a public official. Pub. Act 83 — 942, § 1, eff. November 23, 1983 (
Section 2 sets out several amendments to the Unified Code which, taken together, (1) expand the powers and duties of the Department of Corrections (DOC) (Pub. Act 83 — 942, § 2, eff. November 23, 1983 (
While section 1 deals with substantive criminal law and section 2 with administrative asрects regarding corrections, neither section contains provisions inconsistent with, or foreign to, the general subject of the “criminal justice system.” People v. Dunigan,
Section 3 of Public Act 83 — 942 amends sectiоn 11 — 74—2 of the Illinois Municipal Code by expanding the definition of “Industrial project” to include:
“construction, remodeling!,] or conversion of a structure to be leased to the Illinois Department of Correctiоns for the purposes of its serving as a correctional institution or facility pursuant to *** the [Unified Code].” (Emphasis added.) Pub. Act 83 — 942, § 3, eff. November 23, 1983 (1983 Ill. Laws at 6208 ) (amending Ill. Rev. Stat. 1981, ch. 24, par. 11 — 74—2(l)(c) (now 65 ILCS 5/11 — 74— 2(l)(c) (West 1998))).
Section 4 of Public Act 83 — 942 similarly amеnds section 2 of the Industrial Building Revenue Bond Act (Pub. Act 83 — 942, § 4, eff. November 23, 1983 (
Section 5 of Public Act 83 — 942 amends section 67.02 of the Civil Administrative Code, expanding the powers and duties of the Department of Central Management Services to include entering “into an agreement with a municipality or county to construct, remodel!,] or convert a structure for the purposes of its serving as a correctional institution.” (Emphasis added.) Pub. Act 83 — 942, § 5, eff. November 23, 1983 (
The number of provisions in an enactment is not determinative of its compliаnce with the single subject rule; likewise, an enactment does not violate the single subject rule simply because it amends a number of acts already in effect. Arangold,
Defendant also argues the legislative history of Public Act 83 — 942 demonstrates the act contains discordant provisions in violation of the • single subject rule. However, because the plain language of the amendments in Public Act 83 — 942 unambiguously demonstrates the contrary, we need not resort to extrinsic statutory construction aids to resolve the issue. People v. Hicks,
III. CONCLUSION
For the reasons stated, we affirm the trial court’s judgment.
Affirmed.
