Corporations Win Big After Supreme Court Ruling on Campaign Spending

WASHINGTON — Overruling two important precedents about the First Amendment rights of corporations, a bitterly divided Supreme Court on Thursday ruled that the government may not ban political spending by corporations in candidate elections.

The 5-to-4 decision was a vindication, the majority said, of the First Amendment’s most basic free speech principle — that the government has no business regulating political speech. The dissenters said that allowing corporate money to flood the political marketplace would corrupt democracy.

The ruling represented a sharp doctrinal shift, and it will have major political and practical consequences. Specialists in campaign finance law said they expected the decision to reshape the way elections were conducted. Though the decision does not directly address them, its logic also applies to the labor unions that are often at political odds with big business.

President Obama called it “a major victory for big oil, Wall Street banks, health insurance companies and the other powerful interests that marshal their power every day in Washington to drown out the voices of everyday Americans.”
