A Nebraska Petition for a Writ of Habeas Corpus Under 28 U.S.C. Sec. 2241 is a legal document filed with a federal court by a person who is currently in custody and who believes they are being unlawfully detained. The petition is a request for the court to examine the legality of the detention and to issue an order directing the custodian of the prisoner to either release the prisoner or to show cause why they are being held. It is a civil action brought by the prisoner against the person or agency that has them in custody. There are two types of Nebraska Petition for a Writ of Habeas Corpus Under 28 U.S.C. Sec. 2241: an initial application and a successive application. An initial application is submitted by the prisoner for the first time, while a successive application is filed by the prisoner after their initial application has been denied or dismissed. Both types of applications must be filed in the federal district court for the district in which the petitioner is being held. The petition must be supported by evidence and legal arguments showing that the petitioner's detention is unlawful.
