A term of parliamentary law which refers to a body of one or more persons appointed by a larger assembly or society, to consider, investigate and/or take action on certain specific matters.
A committee only has those powers which have been assigned to it by the constituent assembly.
Most are merely created to study matters in detail and to then report to the larger group.
This saves the larger assembly time when it meets and allows it to review and approve a greater number of items, relying on the committee’s report and recommendations.
Committees are either standing or ad hoc (this latter kind is also known as a "special committee).
