When did the Supreme Court decide McCutcheon v. Federal Election Commission?

The U.S. Supreme Court decided McCutcheon v. Federal Election Commission on April 2, 2014.1

In a 5–4 ruling, the Court struck down aggregate limits on the total amount of money an individual could contribute to federal candidates, political party committees, and noncandidate political action committees during a two-year election cycle. The Court held that these aggregate limits violated the First Amendment guarantees of freedom of speech and freedom of association. The decision did not affect the "base limits," which restrict the amount an individual may contribute to any single candidate or committee.1
