In the case of Hamilton v. Alabama, the U.S. Supreme Court ruled in favor of defendant Clarence Earl Hamilton who was convicted for burglary by an Alabama court without legal representation present during his arraignment. The Supreme Court overturned this conviction on grounds that it violated the Sixth Amendment right to counsel as applied to states through the Fourteenth Amendment's Due Process Clause. The court held that a lawyer must be provided at every critical stage of criminal proceedings where substantial rights may be affected, including arraignments which are considered crucial stages under Alabama law due to potential defenses and pleas being irretrievably lost if not raised then.

In the case of Hamilton v. Alabama, there was no recorded dissenting opinion. The Supreme Court ruled unanimously in favor of Hamilton, stating that his rights under the Sixth and Fourteenth Amendments were violated when he was arraigned without counsel present to represent him. This decision reinforced the principle that a defendant has a constitutional right to legal representation from their first appearance before a judicial officer where they learn the charge against them and their liberty is subject to restriction.
