Citizens United v. Federal Election Commission

Citizens United v. Federal Election Commission (2010) is a landmark Supreme Court case that challenged campaign finance laws. The Court ruled that the government cannot limit independent spending by corporations and unions in elections, viewing such spending as free speech under the First Amendment. This decision allowed these entities to spend unlimited amounts on political advertising, significantly changing the landscape of campaign financing and raising concerns about the influence of money in politics. The ruling sparked a debate about the balance between free speech and the integrity of electoral processes.
