supermajority

Two-thirds vote threshold

A supermajority is a threshold higher than a simple majority, typically two-thirds or three-fifths, required to pass certain measures.

Constitutional amendments, treaty ratifications, and veto overrides often require supermajorities to ensure broad consensus: The bill passed the Senate but fell short of the supermajority needed to override the veto.
