People v. Griffin

Summary

The Illinois Supreme Court held that the same "colorable claim" standard for actual‑innocence petitions applies whether a petitioner was convicted at trial or entered a guilty plea, and that each claim in a successive post‑conviction petition must satisfy its applicable standard—specifically, an ineffective‑assistance claim must meet the cause‑and‑prejudice test before leave to file may be granted. The court affirmed the appellate court’s grant of leave on the actual‑innocence claim, reversed its handling of the ineffective‑assistance claim, and remanded for further determination of cause and prejudice.
