Whether the Supreme Court was bound by South Carolina’s determination that the students’ conduct constituted breach of the peace under state law.
Holding
No. The Court could accept the state courts’ construction of state law while independently reviewing the full record to determine whether the convictions violated the Federal Constitution.
Reasoning
The Court declined to decide the students’ separate due-process argument that the evidence was wholly insufficient to establish breach of the peace under South Carolina law. It accepted, for purposes of the case, the state courts’ conclusion that the conduct fit that broadly defined offense.
But state-law characterization did not end the constitutional inquiry. When criminal convictions allegedly burden First Amendment freedoms, the Supreme Court must independently examine the entire record to determine whether the State has punished constitutionally protected expression. A State cannot avoid federal constitutional limits merely by labeling protected activity a breach of the peace.
