THE PEOPLE OF THE STATE OF ILLINOIS, ) Appeal from the Plaintiff-Appellee, ) Circuit Court of v. ) Peoria County DEOTHIUS N. MACK, ) No. 10CF11 Defendant-Appellant. ) ) Honorable ) Katherine S. Gorman, ) Judge Presiding.

JUSTICE KNECHT delivered the judgment of the court. Presiding Justice Steigmann and Justice DeArmond concurred in the judgment.

ORDER

¶1 Held: The appellate court reversed the trial court’s dismissal of defendant’s postconviction petition and remanded the matter for substantial compliance with Illinois Supreme Court Rule 651(c) (eff. July 1, 2017).

¶2 In April 2021, defendant, Deothius N. Mack, filed a pro se postconviction petition

pursuant to the Post-Conviction Hearing Act (Act) (725 ILCS 5/122-1 et seq. (West 2020)). In

July 2021, the trial court appointed postconviction counsel. Thereafter, counsel filed an amended

petition and a certificate under Illinois Supreme Court Rule 651(c) (eff. July 1, 2017). Following

an August 2024 hearing, the court dismissed defendant’s petition.

¶3 Defendant appeals, arguing postconviction counsel failed to substantially comply

with Rule 651(c). For the following reasons, we reverse and remand for further postconviction

proceedings.

¶4 I. BACKGROUND ¶5 In January 2010, the State charged defendant with attempted first degree murder

(720 ILCS 5/8-4(a), 9-1(a)(1) West 2008)) (count I), three counts of armed robbery (id. § 18-

2(a)(2)-(4)) (counts II-IV), and aggravated battery with a firearm (id. § 12-4.2(a)(1)) (count V).

¶6 In November 2010, defendant pleaded guilty to count V. In exchange, the State

dismissed the remaining counts. There was no agreement as to the sentence. In January 2011, the

trial court sentenced defendant to 24 years’ imprisonment, followed by 3 years of mandatory

supervised release (MSR).

¶7 In February 2011, defendant and his counsel both filed motions to reconsider the

sentence. Several years passed without a ruling on either motion. After defendant sent several

letters to the trial court, a hearing was held, and the court denied the motions in October 2018.

Defendant appealed, and the case was remanded for the filing of a new postplea motion, the

filing of an Illinois Supreme Court Rule 604(d) (eff. July 1, 2017) certificate, and a de novo

hearing on the postplea motion. People v. Mack, No. 3-18-0597 (2019) (unpublished order under

Illinois Supreme Court Rule 23).

¶8 On remand, defendant filed a “motion to reconsider sentence or to withdraw plea

of guilty.” In August 2019, the trial court held a hearing on the motion. Counsel declined to

present any argument on the portion of the motion to withdraw the guilty plea. The court denied

the motion. Defendant appealed, and the reviewing court affirmed his sentence. People v. Mack,

2020 IL App (3d) 190522-U, ¶ 17.

¶9 In April 2021, defendant filed a pro se postconviction petition. The petition

alleged plea counsel was ineffective for (1) refusing to challenge defendant’s warrantless arrest,

(2) refusing to subpoena the police interview video of defendant, (3) advising defendant to plead

guilty after his codefendant was acquitted, (4) pressuring defendant to plead guilty by

-2- inaccurately claiming he would receive 55 years in prison if he went to trial, and (5) erroneously

advising defendant the State had agreed to a determinate sentence, namely, a 24-year sentence

including MSR, as opposed to a non-negotiated plea. The petition further alleged these errors

rendered his guilty plea involuntary and absent these errors, defendant would not have pleaded

guilty and would have insisted on going to trial. Defendant attached his notarized affidavit to the

petition.

¶ 10 In July 2021, the trial court docketed the petition for second-stage proceedings

and appointed postconviction counsel to represent defendant.

¶ 11 In January 2024, postconviction counsel filed an amended petition. The amended

petition incorporated the pro se petition and affidavit by reference. The petition reasserted the

pro se claims of ineffective assistance of counsel. As to prejudice, the amended petition stated,

but for counsel’s unprofessional errors, there was a significant chance defendant’s warrantless

arrest or purported confession could provide a basis for a motion to suppress or a “coercion

defense.” Had the State’s evidence been excluded, the petition argued, counsel could have

negotiated a more favorable plea agreement for defendant. In April 2024, counsel filed a

certificate asserting compliance with Rule 651(c).

¶ 12 On August 15, 2024, the State filed a motion to dismiss the petition. The State

argued defendant failed to establish prejudice, as the State agreed to dismiss four charges with

much higher sentencing ranges in exchange for defendant’s guilty plea on the charge with the

lowest sentencing range. The State alleged defendant’s claim as to the potential sentencing range

was contradicted by the record, where defendant was properly admonished as to the potential

sentencing range before pleading guilty. The State noted defendant conceded the record

contradicted his allegation regarding a determinate sentence. Finally, the State maintained

-3- defendant forfeited his claims because he could have raised them in his motion to withdraw his

guilty plea or on direct appeal and failed to do so.

¶ 13 On August 23, 2024, the trial court held a hearing on the State’s motion.

Following the arguments of the parties, the court took the matter under advisement.

¶ 14 In September 2024, the trial court granted the State’s motion and dismissed the

amended petition.

¶ 15 This appeal followed.

¶ 16 II. ANALYSIS

¶ 17 On appeal, defendant argues he was denied the reasonable assistance of

postconviction counsel where counsel failed to put his pro se claims into proper legal form in the

¶ 18 A. Waiver and Forfeiture

¶ 19 The State contends defendant waived any challenge to plea counsel’s

effectiveness by voluntarily pleading guilty. “It has been long established in Illinois caselaw that

a voluntary guilty plea waives all nonjurisdictional errors, including constitutional defects.”

People v. Johnson, 2021 IL App (1st) 152310, ¶ 21. An exception to this rule applies where a

defendant claims that his or her guilty plea was involuntary because plea counsel provided

deficient advice. People v. Smith, 383 Ill. App. 3d 1078, 1085 (2008). In this case, defendant

alleged numerous claims of ineffective assistance, including that plea counsel refused to

investigate certain evidence and provided erroneous advice regarding the State’s offer and

sentencing. These claims directly relate to the voluntariness of his plea and whether plea counsel

provided deficient advice. Accordingly, defendant has not waived his claims on this basis.

¶ 20 The State further contends defendant waived his claims by failing to move to

-4- withdraw his guilty plea before pursuing his postconviction appeal. Rule 604(d) provides, in

relevant part, the following:
