WASHINGTON — The Supreme Court ruled today that corporations may spend as freely as they like to support or oppose candidates for president and Congress, easing decades-old limits on business efforts to influence federal campaigns.
By a 5-4 vote, the court overturned a 20-year-old ruling that said companies can be prohibited from using money from their general treasuries to produce and run their own campaign ads. The decision, which almost certainly will also allow labor unions to participate more freely in campaigns, threatens similar limits imposed by 24 states.
It leaves in place a prohibition on direct contributions to candidates from corporations and unions.
Critics of the stricter limits have argued that they amount to an unconstitutional restraint of free speech, and the court majority agreed.
“The censorship we now confront is vast in its reach,” Justice Anthony Kennedy said in his majority opinion, joined by his four more conservative colleagues.
Strongly disagreeing, Justice John Paul Stevens said in his dissent, “The court’s ruling threatens to undermine the integrity of elected institutions around the nation.”
Justices Ruth Bader Ginsburg, Stephen Breyer and Sonia Sotomayor joined Stevens’ dissent, parts of which he read aloud in the courtroom.
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.
Advocates of strong campaign finance regulations have predicted that a court ruling against the limits would lead to a flood of corporate and union money in federal campaigns as early as this year’s midterm congressional elections.
“It’s the Super Bowl of bad decisions,” said Common Cause president Bob Edgar, a former congressman from Pennsylvania.
The decision removes limits on independent expenditures that are not coordinated with candidates’ campaigns.
The case does not affect political action committees, which mushroomed after post-Watergate laws set the first limits on contributions by individuals to candidates. Corporations, unions and others may create PACs to contribute directly to candidates, but they must be funded with voluntary contributions from employees, members and other individuals, not by corporate or union treasuries.
Chief Justice John Roberts and Justices Samuel Alito, Antonin Scalia and Clarence Thomas joined Kennedy to form the majority in the main part of the case.
Roberts, in a separate opinion, said that upholding the limits would have restrained “the vibrant public discourse that is at the foundation of our democracy.”
Stevens complained that those justices overreached by throwing out earlier Supreme Court decisions that had not been at issue when this case first came to the court.
“Essentially, five justices were unhappy with the limited nature of the case before us, so they changed the case to give themselves an opportunity to change the law,” Stevens said.
The case began when a conservative group, Citizens United, made a 90-minute movie that was very critical of Hillary Rodham Clinton as she sought the Democratic presidential nomination. Citizens United wanted to air ads for the anti-Clinton movie and distribute it through video-on-demand services on local cable systems during the 2008 Democratic primary campaign.
But federal courts said the movie looked and sounded like a long campaign ad, and therefore should be regulated like one.
The movie was advertised on the Internet, sold on DVD and shown in a few theaters. Campaign regulations do not apply to DVDs, theaters or the Internet.
The court first heard arguments in March, then asked for another round of arguments about whether corporations and unions should be treated differently from individuals when it comes to campaign spending.
The justices convened in a special argument session in September, Sotomayor’s first. The conservative justices gave every indication then that they were prepared to take the steps they did on Thursday.
The justices, with only Thomas in dissent, did uphold McCain-Feingold requirements that anyone spending money on political ads must disclose the names of contributors.
