348 U.S. 483 (1955)
Williamson v. Lee Optical of Oklahoma, Inc.
Does the Oklahoma law regulating the practice of optometry and related sales violate the Due Process Clause of the Fourteenth Amendment by unreasonably restricting business operations?
Economic regulations will be upheld if they are rationally related to a legitimate government interest. Under the Due Process Clause, states have wide latitude to regulate business activities provided there is a conceivable public benefit.
The Supreme Court upheld the Oklahoma statute, affirming that the law was a valid exercise of the state's regulatory power under the Police Powers Clause, and did not violate the Due Process Clause.
Williamson v. Lee Optical is significant because it firmly established the supremacy of legislative judgment over judicial intervention concerning economic regulations under the rational basis review. It reinforced the doctrine that economic and social regulations are constitutionally permissible as long as they bear some rational relation to a legitimate government interest. Law students must understand this case as it illustrates the deferential approach courts adopt when reviewing economic regulation, emphasizing separation of powers and the role of the judiciary.
