A Nevada Motion To Vacate, Set Aside Or Correct Sentence By Person In Federal Custody is a legal document that can be filed in a federal court by a person in federal custody in order to challenge the legality of their sentence. It can be used to request that the court set aside or vacate the sentence, or to correct an illegal sentence or a sentence that was imposed in a manner which violates the law. There are two main types of Nevada Motion To Vacate, Set Aside Or Correct Sentence By Person In Federal Custody: a 2255 motion and a 2241 motion. A 2255 motion is used when a person is challenging the legality of a sentence that was imposed by a federal court. It is also used for claims of ineffective assistance of counsel, violations of the Constitution, or newly discovered evidence that could have resulted in a different sentence. A 2241 motion is used to challenge the legality of a sentence imposed by an administrative agency (such as the Bureau of Prisons). It can also be used for claims of ineffective assistance of counsel, violations of the Constitution, or newly discovered evidence that could have resulted in a different sentence.
