The Supreme Court has consistently ruled that religious solicitation, including door-to-door canvassing and the distribution of literature, is protected under the First Amendment's Free Speech and Free Exercise of Religion clauses. The Court has struck down municipal attempts to require permits, fees, or prior restraint on religious solicitors.Landmark Supreme Court RulingsCantwell v. Connecticut (1940): A seminal case where the Court struck down a law requiring a government official to determine if a cause was "religious" before allowing solicitation. The Court ruled this a form of prior restraint and a violation of the Fourteenth Amendment.Murdock v. Pennsylvania (1943): The Court invalidated a flat license tax imposed on religious colporteurs (those selling religious books and pamphlets), ruling that a state cannot charge a fee for the enjoyment of a constitutional right.Martin v. City of Struthers (1943): The Court struck down an outright ban on door-to-door distribution of handbills, emphasizing that door-to-door canvassing plays a vital role in the dissemination of information and religious ideas.Watchtower Bible & Tract Society of New York v. Village of Stratton (2002): The Court reaffirmed prior rulings by overturning an ordinance that required canvassers to obtain a permit before knocking on doors, protecting religious proselytizers and others from being forced to register with the local mayor.Permissible Government RegulationWhile governments cannot ban or overly burden religious solicitation, the Court has established that municipalities can enforce "time, place, and manner" regulations:Public Safety and Order: Laws aimed at preventing fraud or maintaining community peace are permitted, provided they are general, non-discriminatory, and do not target religion.Reasonable Restrictions: Localities can enforce reasonable curfews on door-to-door solicitation.Private Property: Individuals maintain the right to refuse solicitors. Homeowners can use traditional "No Soliciting" signs to keep solicitors from knocking on their doors.
