3. The Senate Parliamentarian:

An important role of the parliamentarian is to decide what can and cannot be done under the Senate's budget reconciliation process under the provisions of the Byrd Rule.[2] These rulings are important because they allow certain bills to be approved by a simple majority, instead of the sixty votes needed to end debate and overcome a filibuster.

The office also refers bills to appropriate committees on behalf of the Senate's Presiding Officer, and referees efforts by the ruling party to change the Senate rules by rulings from the chair. The parliamentarian is appointed by and serves at the pleasure of the Senate Majority Leader. Traditionally, the parliamentarian is chosen from senior staff in the parliamentarian office, which helps ensure consistency in the application of the Senate's complex rules. The last two parliamentarians have served under both Republican and Democratic Senate leaders.
