Lochner v. New York, 198 U.S. 45 (1905), was a landmark decision of the U.S. Supreme Court in which the Court ruled that a New York state law setting maximum working hours for bakers violated the bakers' right to freedom of contract under the Fourteenth Amendment to the U.S. Constitution. The decision has been effectively overturned.The underlying case began in 1899 when Joseph Lochner, a German immigrant who owned a bakery in Utica, New York, was charged with violating New York's Bakeshop Act of 1895. The Bakeshop Act had made it a crime for New York bakeries to employ bakers for more than 10 hours per day or 60 hours per week. He was convicted and ultimately appealed to the U.S. Supreme Court. A five-justice majority of the Supreme Court held that the law violated the due process clause, stating that the law constituted an "unreasonable, unnecessary and arbitrary interference with the right and liberty of the individual to contract". Four dissenting justices rejected that view, and the dissent of Oliver Wendell Holmes Jr., in particular, became one of the most famous opinions in US legal history.Lochner is one of the most controversial decisions in the Supreme Court's history and gave the name to what is known as the Lochner era. During that time, the Supreme Court issued several decisions invalidating federal and state statutes that sought to regulate working conditions during the Progressive Era and the Great Depression. The period ended with West Coast Hotel Co. v. Parrish (1937) in which the Supreme Court upheld the constitutionality of minimum wage legislation enacted by Washington State.



The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate and largely discretionary appellate jurisdiction over all federal and state court cases that involve a point of federal law, and original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." The Court holds the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law. However, it may act only within the context of a case in an area of law over which it has jurisdiction. The Court may decide cases having political overtones but has ruled that it does not have power to decide non-justiciable political questions.

Established by Article Three of the United States Constitution, the composition and procedures of the Supreme Court were initially established by the 1st Congress through the Judiciary Act of 1789. As later set by the Judiciary Act of 1869, the Court consists of the chief justice of the United States and eight associate justices. Each justice has lifetime tenure, meaning they remain on the Court until they die, retire, resign, or are removed from office. When a vacancy occurs, the president, with the advice and consent of the Senate, appoints a new justice. Each justice has a single vote in deciding the cases argued before the Court. When in majority, the chief justice decides who writes the opinion of the court; otherwise, the most senior justice in the majority assigns the task of writing the opinion.

The Court meets in the Supreme Court Building in Washington, D.C. Its law enforcement arm is the Supreme Court Police.
