Supreme Court rolls back limits on spending by corporations in federal campaigns

Court rolls back campaign spending limits

WASHINGTON — The Supreme Court has ruled that corporations may spend freely to support or oppose candidates for president and Congress, easing decades-old limits on their participation in federal campaigns.

The court on Thursday overturned a 20-year-old ruling that said corporations can be prohibited from using money from their general treasuries to pay for campaign ads. The decision almost certainly will also allow labor unions to participate more freely in campaigns and threatens similar limits imposed by 24 states.

The justices also struck down part of the landmark McCain-Feingold campaign finance bill that barred union- and corporate-paid issue ads in the closing days of election campaigns.
