Passage of a motion when no participant objects; effectively waiving the need to hold a vote

In parliamentary procedure, unanimous consent, also known as general consent, or in the case of the parliaments under the Westminster system, leave of the house (or leave of the senate), is a situation in which no member present objects to a proposal.

Generally, in a meeting of a deliberative assembly, business is conducted using a formal procedure of motion, debate, and vote. However, if there are no objections, action could be taken by unanimous consent. The procedure of asking for unanimous consent is used to expedite business by eliminating the need for formal votes on routine questions in which the existence of a consensus is likely. The principle behind it is that procedural safeguards designed to protect a minority can be waived when there is no minority to protect.'''''' It is sometimes used simply as a time saving device, especially at the end of the session. Sometimes members do not want a formal recorded vote on the issue, or they know that they would lose such a vote and do not feel a need to take time on it.

Action taken by unanimous consent does not necessarily mean that it was taken by a unanimous vote. It does not necessarily mean that every member of the body would have voted in favor of the proposal. It may mean that members feeling that it would be useless to oppose a matter would simply acquiesce. Unanimous consent merely requires that no representative of those present has asked to take a recorded vote or has requested quorum verification. For that reason, a claim that a piece of legislation was passed "unanimously", when it was really passed via "unanimous consent", can be misleading as to its level of support.

Certain rights can only be waived by unanimous consent. For example, in disciplinary procedures, a single member can require the vote on the imposition of a penalty to be taken by ballot. When an item is before the assembly for action, such as a resolution, it is the right of every member to have it read once. Another case of this requirement is the reading of the minutes. Unanimous consent is required to not do the reading. Any member can request that the minutes be read and it would have to be done.

Unanimous consent can be obtained by the chair asking if there are any objections to doing something. For instance, the chair may state, "If there is no objection, the motion will be adopted. [pause] Since there is no objection, the motion is adopted." Objections are sometimes used as a delaying tactic. The objector may have no disagreement with the proposal at issue, but chooses to object in order to force a time consuming formal vote, which may include a period of debate as well. If no one has corrections to the minutes, they are approved without a formal vote by unanimous consent. In this special case of unanimous consent, the only way to object to the approval of the minutes is to offer a correction to it. In this special case of unanimous consent, the only way to object to the election of a candidate is to nominate and vote for someone else. A meeting could be adjourned by unanimous consent. If no one has any further business at the end of a meeting, the chair simply declares the meeting adjourned without a formal motion or a formal vote.

In parliaments under the Westminster system, leave of the house or leave of the senate is a similar concept to requiring unanimous consent. If a member asks for leave to be granted to do something that is different from the rules, a single objection can defeat the request.

Unanimous consent may be used as part of a consensus decision making process. In that process, unanimous consent does not necessarily mean unanimous agreement (see ).
