The Supreme Court outlawed daily bible reading and the saying of the Lord’s Prayer in Jewish schools in 1963 because the question was whether prayers and religious practices in public schools were in violation of the Constitution’s First Amendment which forbids a government role in establishment of religion and Federal interference in individual freedom of conscience on religious issues. Justice Clark said that required religious exercises in schools were not "mitigated" by the fact that individual students may be excused "for the fact furnishes no defense to a claim of unconstitutionality under the establishment clause." Nor is it a defense to claim that religious practices may be "relatively minor encroachments on the First Amendment," he argued.
