Final answer:
To show ineffective assistance of counsel, a defendant must prove that their lawyer's performance was deficient and that there is a reasonable probability that with competent representation, the result would have been different, under the standards set by Strickland v. Washington.
Step-by-step explanation:
Understanding Ineffective Assistance of Counsel
To show ineffective assistance of counsel, the Supreme Court's landmark decision in Strickland v. Washington established a two-pronged test. Firstly, a criminal defendant must demonstrate that the counsel’s performance was deficient and fell below an objective standard of reasonableness. Secondly, it must be shown that there is a reasonable probability that, had the counsel provided competent representation, the outcome of the proceeding would have been different.
Furthermore, in Padilla v. Kentucky, it was determined that criminal defense attorneys must inform their clients about the risk of deportation under specific circumstances, highlighting the importance of competent legal guidance in all aspects of a criminal proceeding, particularly those with implications beyond the immediate case.
Moreover, the Sixth Amendment guarantees the right to an attorney, reinforcing the necessity for competent legal representation, as established by cases such as Gideon v. Wainwright, where indigent defendants are entitled to legal counsel provided by the state. This right safeguards against unfair trials and ensures a more reliable justice system.
