Margaret Papachristou and others (defendants) were arrested and charged with vagrancy. Florida’s vagrancy ordinance prohibited several general activities, among them loafing, wandering or strolling without any lawful purpose, hanging around places where liquor is sold, common night walking, and men “habitually living upon the earnings of their wives or minor children,” despite being able to work. The trial court convicted the defendants for violating the vagrancy ordinance, and the court of appeals affirmed. The defendants appealed on constitutional grounds. The United States Supreme Court granted certiorari.
