- The case was about money and political campaigns.
- The Court made its decision by a 5–4 vote.
- The Court ruled that corporations and labor unions can spend money independently to support or oppose political candidates.
- The decision changed earlier limits on this type of political spending.
- After the decision, outside spending in federal elections increased greatly.
- Some political groups can spend money without publicly identifying all of their donors.
- This is sometimes called “dark money.”
Critics of the decision say large amounts of money can give wealthy groups too much influence in elections.
- Justice John Paul Stevens disagreed with the Court's decision.
- He warned that the decision could hurt public trust in elected government.
- Citizens United continues to be an important debate about free speech, money, and elections in the United States.
