2022 IL App (4th) 200198-U
Ill. App. Ct.2022Background:
- In July 2008 defendant Clarance Thompkins (born Aug. 10, 1989) committed home invasion and armed robbery; convicted after a September 2011 bench trial.
- He was 18 at the time of the offense and 22 at sentencing; received concurrent 30-year terms plus a 15-year firearm add‑on, total 45 years.
- Defendant filed multiple postconviction petitions; earlier petitions were dismissed and prior appeals affirmed.
- After People v. Buffer (2019) he filed a successive postconviction motion arguing his 45‑year term was a de facto life sentence for a young adult and violated the Eighth Amendment given adolescent brain‑development science.
- The trial court denied leave to file the successive petition (finding forfeiture of the state constitutional claim and that Miller protections do not extend to 18‑year‑old offenders); the appellate court affirmed.
Issues:
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Thompkins’ 45‑year sentence for an offense committed at age 18 violates the Eighth Amendment and/or the Illinois proportionate penalties clause | People: Eighth Amendment/Miller protections apply only to those under 18; successive petition fails cause-and-prejudice | Thompkins: 45 years is a de facto life sentence for an 18‑year‑old; Miller and Buffer support extending juvenile‑like protections to young adults based on brain science | Court: Forfeited the state proportionate‑penalties claim; Eighth Amendment claim fails as a matter of law because Miller protects only those <18, so denial of leave to file successive petition affirmed |
