Barbier v. Illinois

Barbier v. Illinois was a significant U.S. Supreme Court case decided in 1885. It addressed the issue of whether a state could regulate prices set by businesses, particularly in the context of public utilities. The Court upheld Illinois' right to regulate the prices that the Barbier Company charged for services because they were seen as a business serving the public. The decision emphasized the government's role in ensuring fair practices and preventing exploitation in industries that provide essential services, laying the groundwork for future regulations in public service sectors.
