Austin v. Michigan Chamber of Commerce, 494 U.S. 652 (1990) is a United States corporate law case of the Supreme Court of the United States holding that the Michigan Campaign Finance Act, which prohibited corporations from using treasury money to make independent expenditures to support or oppose candidates in elections, did not violate the First and Fourteenth Amendments. The Court upheld the restriction on corporate speech, stating, "Corporate wealth can unfairly influence elections"; however, the Michigan law still allowed the corporation to make such expenditures from a segregated fund.
