Final answer:
The U.S. Supreme Court case Gideon v. Wainwright confirmed the Sixth Amendment right to assistance of counsel, ensuring that indigent defendants receive legal representation at state expense for a fair trial.
Step-by-step explanation:
In the 1963 case Gideon v. Wainwright, the U.S. Supreme Court confirmed the Sixth Amendment right to assistance of counsel. This landmark decision established that states are required to provide legal representation to defendants who are unable to afford an attorney, ensuring their right to a fair trial. It recognized that for a trial to be fair, the defendant must have the means to mount an effective defense, leading to the requirement that state courts appoint attorneys for indigent defendants facing felony charges.
Following this decision, the Court extended the ruling to cover any case where the accused could face a potential loss of liberty. The ruling emphasized that the right to counsel is essential for the protection of fundamental rights under the 14th Amendment, and subsequent cases have further interpreted this right to include competent legal representation.
