A Motion to Vacate Sentence (Sec. 2255) is a legal motion that allows a person convicted of a federal crime to challenge their conviction or sentence in court. It is available under 28 U.S.C. § 2255, which allows a person to challenge the legality of their federal conviction or sentence in the court in which they were convicted. The motion must be filed within one year of the conviction or sentence being finalized, and must be based on a violation of the defendant's federal constitutional rights, an error of law in the conviction or sentence, or the sentence being imposed in violation of the law. Types of Motion to Vacate Sentence (Sec. 2255) include: • Ineffective Assistance of Counsel: This motion is used when a defendant claims that their attorney was ineffective or provided inadequate counsel. • Entrapment: This motion is used to challenge a conviction that was based on entrapment by law enforcement. • Abuse of Discretion: This motion is used when a judge’s decision is deemed to be an abuse of discretion. • Insufficiency of the Evidence: This motion is used to challenge a conviction based on insufficient evidence. • Sentencing Errors: This motion is used to challenge a sentence that is considered to be excessive or to argue that the sentence was imposed in violation of the law.
