Override

A veto override is Congress’s approval of a vetoed bill by the required supermajorities.

Definition

A veto override occurs when both the House and Senate repass a vetoed bill by two-thirds votes. The bill then becomes law without the president’s signature.

Why It Matters

Override power prevents the president from having an absolute veto.

How It Works

The chamber receiving the veto votes first, followed by the other chamber. Both must reach two-thirds.

History

The Constitution has allowed overrides since 1789, though they are relatively uncommon.

Example

A broadly supported defense bill may become law over a presidential veto.

Common Misconceptions

  • A simple majority can override a veto.
  • Only one chamber must act.
  • Courts conduct the override vote.
