Case Categories: Blue Laws and Religious Freedom

This is a list of significant court cases related to blue laws and religious freedom. The establishment clause of the First Amendment prohibits any law “respecting the establishment of religion.” By designating Sunday as a Sabbath and by restricting activities of individuals on that day, states with Sunday blue laws have arguably favored Christianity over religions that celebrate different Sabbaths. Litigation over blue laws were common throughout the 19th century and into the 20th century.
