A Louisiana Petition for Writ of Habeas Corpus Under 28 U.S.C. 2254 is a legal document that is filed in federal court to challenge the legality of a person's imprisonment, detention, or other form of confinement. The petition is a legal request for the court to order the release of the person from custody. It is typically used when a person believes they are being unlawfully detained, or when state law has not been properly followed in their incarceration or confinement. The petition may be filed by the prisoner, a friend or family member, or an attorney. There are two types of Louisiana Petition for Writ of Habeas Corpus Under 28 U.S.C. 2254: the original writ and the successive writ. An original writ is filed when a prisoner believes their conviction or sentence based on state law violates the United States Constitution. A successive writ is filed when a prisoner believes their conviction or sentence violates a United States Supreme Court ruling. The writs must be filed in the federal district court in the district where the conviction occurred.
