Ineffective Assistance of Counsel

 The Supreme Court has held that part of the right to counsel is a right to effective assistance of counsel.  Proving that their lawyer was ineffective at trial is a way for convicts to get their convictions overturned, and therefore ineffective assistance is a common heabus corpus claim.  To prove ineffective assistance, a defendant must show (1) that their trial lawyer's performance fell below an "objective standard of reasonableness" and (2) "a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different." Strickland v. Washington, 466 U.S. 668 (1984).
