Austin v. Michigan Chamber of Commerce, 494 U.S. 652 (1990), was a decision of the Supreme Court of the United States regarding campaign finance regulations. Thurgood Marshall's majority opinion held that the Michigan Campaign Finance Act, which burdened political speech by prohibiting corporations from using treasury money to make independent expenditures to support or oppose candidates in elections, was appropriately justified by a compelling state interest so as to overcome a First Amendment challenge. The court also found no Fourteenth Amendment violation, stating that Congress could treat press corporations and nonpress corporations differently without violating the Equal Protection Clause. Upholding the restriction on corporate political speech, the court stated that "corporate wealth can unfairly influence elections". The Michigan law, however, continued to allow corporations to make such expenditures from a segregated fund.
