Zorach v. Clauson

New York City's release-time program let public-school students leave school grounds, with parental consent, to attend off-campus religious instruction or services; students who did not participate remained in class as usual, and no religious instruction occurred on public-school premises. Zorach (plaintiff) sued, claiming the program violated the First Amendment's Religion Clauses.

Whether a program allowing students to leave school for religious services violates the Religion Clauses of the First Amendment.
