Title: Judicial review in the United States
Content:  House, 116 to 39. That measure died in the Senate, partly because the bill was unclear about how the bill's own constitutionality would be decided. Many other bills have been proposed in Congress that would require a supermajority in order for the justices to exercise judicial review. During the early years of the United States, a two-thirds majority was necessary for the Supreme Court to exercise judicial review; because the Court then consisted of six members, a simple majority and a two-thirds majority both required four votes.
