Title 28 › PART VI — PARTICULAR PROCEEDINGS › CHAPTER 153 — HABEAS CORPUS › § 2244
Federal judges must not re‑hear a federal prisoner’s habeas request about detention if a federal court already decided the same issue on an earlier habeas petition, except as allowed under section 2255. For state prisoners using a federal habeas petition under section 2254, any claim repeated from an earlier petition must be dismissed. A new claim in a later petition is dismissed unless the prisoner shows either a new constitutional rule the Supreme Court has made retroactive, or new facts that could not have been found earlier with reasonable diligence and that, if proven, would show by clear and convincing evidence that no reasonable factfinder would have found the prisoner guilty but for a constitutional error. Before filing a second or successive petition in a district court, the prisoner must ask the court of appeals for permission. A three‑judge panel of the appeals court decides and must allow or deny the request within 30 days. The appeals court only allows filing if the petition makes a prima facie showing it meets the rules. That decision cannot be appealed or reheard. If the appeals court allows filing, the district court must still dismiss any claim that does not meet these requirements. If the Supreme Court already decided an issue on a prisoner’s appeal, that decision is final on the facts and law actually decided, unless the prisoner shows a material, controlling fact that was not in the Supreme Court record and could not have been found with reasonable diligence. State‑court prisoners have a one‑year deadline to file a federal habeas petition. The one year starts from the latest of: when the judgment became final after direct review or the time to seek it ended; when a state action blocking filing was removed; when the Supreme Court first recognized a new constitutional right and made it retroactive; or when the factual basis could have been found with due diligence. Time spent on a properly filed state post‑conviction or other collateral review while it is pending does not count toward the one‑year limit.
