Randall v. Sorrell

Randall v. Sorrell, 548 U.S. 230 (2006), is a decision by the Supreme Court of the United States involving a Vermont law which placed a cap on financial donations made to politicians. The court ruled that Vermont's law, the strictest in the nation, unconstitutionally hindered the citizens' First Amendment right to free speech. A key issue in the case was the 1976 case "Buckley v. Valeo", which many justices felt needed to be revisited.
Opinion of the Court.
The 6-3 ruling dealt with three individual issues before the court.
The State of Vermont argued that new circumstances and experiences since "Buckley v. Valeo" was decided in 1976 suggested that the law should be upheld as Constitutional. 
The Supreme Court ruled against the state of Vermont on all three issues, reaffirming both "Buckley" and "Colorado Republican Federal Campaign Committee" and striking down the law as unconstitutional. "Randall" is particularly important as the first case in which the Supreme Court has struck down a contribution limit as unconstitutionally low.
