Tennessee Motion To Vacate, Set Aside, Or Correct A Sentence By A Person In Federal Custody is a legal procedure that allows a person in federal custody to challenge the validity of their sentence. This motion allows the person in federal custody to ask the court to change the sentence they were given, either to reduce the prison term, change the terms of their supervised release, or even dismiss the conviction entirely. There are three types of Tennessee Motion To Vacate, Set Aside, Or Correct A Sentence By A Person In Federal Custody. These include: 1) Motion to Vacate, Set Aside, or Correct Sentence; 2) Motion to Reduce Sentence Pursuant to 18 U.S.C. § 3582(c); and 3) Motion to Correct Sentence Pursuant to 28 U.S.C. § 2255. The Motion to Vacate, Set Aside, or Correct Sentence is used to challenge the validity of the sentence, while the Motion to Reduce Sentence Pursuant to 18 U.S.C. § 3582(c) is used when the person in federal custody believes the sentence was overly harsh. The Motion to Correct Sentence Pursuant to 28 U.S.C. § 2255 is used when the person in federal custody believes that they were convicted of a crime using a law that was later found to be unconstitutional.
