Post-Conviction Relief: A Second Chance After a Final Verdict

When a criminal conviction becomes final — meaning your direct appeal has been exhausted or the time to appeal has passed — post-conviction relief is the legal mechanism through which you can still challenge that conviction or sentence.

Post-conviction is not a second trial. It is a collateral attack: a separate proceeding in which you argue that your imprisonment is constitutionally unlawful.

State Post-Conviction Remedies

Every state has its own procedures. In Michigan, the primary vehicle is a motion for relief from judgment under Michigan Court Rule 6.500. In Arizona, defendants use Rule 32 petitions. In North Carolina, the Motion for Appropriate Relief (MAR) serves the same function.

Common grounds for post-conviction relief include:

  • Newly discovered evidence: that could not have been found at trial with due diligence
  • Brady violations: — prosecution suppressed favorable evidence
  • Ineffective assistance of counsel: under the Strickland standard
  • Change in law: — a new Supreme Court ruling applies retroactively to your case
  • Actual innocence: — evidence establishing you did not commit the offense
  • Illegal sentence: — your sentence exceeds what the law allows

    • Federal Habeas Corpus Under 28 U.S.C. § 2254

    After exhausting state remedies, most state prisoners can file a federal habeas petition. Federal habeas is a narrow remedy — federal courts defer to state court rulings unless they were "contrary to, or an unreasonable application of, clearly established federal law."

    The one-year statute of limitations under AEDPA (the Antiterrorism and Effective Death Penalty Act) is critical. Missing the deadline typically ends your federal options permanently.

    The Exhaustion Requirement

    Before a federal court will hear your claims, you must have "exhausted" them — meaning you raised them at every level of the state court system. Failing to exhaust a claim in state court generally results in procedural default, which bars federal review.

    What Post-Conviction Relief Can Do for You

    Post-conviction relief can result in:

  • Vacatur of your conviction: and a new trial
  • Resentencing: with a shorter sentence
  • Release from prison: in cases of actual innocence
  • Expungement eligibility: once the conviction is vacated

    • Time Is Your Enemy

    Every post-conviction remedy has a deadline. State rules limit the time to file motions for relief from judgment. AEDPA imposes a one-year window for federal habeas. Do not assume you have unlimited time to explore your options.

    If you believe your conviction or sentence is legally flawed, contact a post-conviction attorney as soon as possible to evaluate your case.
