Federal Election Commission, case in which the U.S. Supreme Court on January 21, 2010, ruled (5–4) that laws that prevented corporations and unions from using their general treasury funds for independent “electioneering communications” (political advertising) violated the First Amendment’s guarantee of freedom of speech. In so doing the court invalidated Section 203 of the federal Bipartisan Campaign Reform Act of 2002 (BCRA)—also known as the McCain-Feingold Act for its sponsors, Sen. John McCain and Sen.
