Filibuster

A filibuster is an attempt to block Senate vote on a bill by debating it at length, by offering numerous procedural motions, or by any other delaying or obstructive actions.

The most famous filibusters were undertaken by Southern Democrats to block civil rights legislation. The record for the longest filibuster is held by Senator Strom Thurmond, who filibustered against the Civil Rights Act of 1957 for 24 hours, 18 minutes.

Origins

The right of unlimited debate in the Senate was rejected by the Founding Fathers. The Continenal Congress adopted Rule 10. It followed the practice of the British Parliament and precedent allowed a simple majority to cut off debate by a motion for "the previous question." This rule was included in sections 8 and 9 of the rules adopted by the first Senate in 1789, was included in Jefferson's Manual of Parliamentary Practice, and was part of the Senate's rules until it was removed in 1806. The change in 1806 allowed unlimited debate.

In practice 19th century filibusters were successful only at the end of a session, when the clock was ticking. The Senate thereby refused to vote on the Wilmot Proviso in 1846.

Until 1975 it took a two-thirds vote to end debate. A rules change that year reduced the number to 60. The effect is that almost all major legislation needs 60 votes to pass the Senate. The exception comes in "reconciliation" bills that deal with the budget.
