Joseph Tipaldo (defendant) managed a laundry in New York City and was charged with violating a state statute that established a minimum wage for women employees. Tipaldo was sent to jail to await trial, and he filed a petition for a writ of habeas corpus in New York state court. He claimed, among other things, that the minimum-wage statute violated the Due Process Clause of the Fourteenth Amendment to the United States Constitution. Tipaldo asserted that New York’s statute was identical to the Washington, D.C., minimum-wage statute held to be unconstitutional in Adkins v. Children’s Hospital, 261 U.S. 525 (1923). The trial court dismissed Tipaldo’s petition, but the New York Court of Appeals reversed and held that the statute was unconstitutional. The United States Supreme Court granted certiorari.
