What type of committee is temporary and becomes nonexistent as soon as the committee's task is completed?

A special committee is established for a specific purpose and has a limited duration. Once it has completed its task or achieved its objective, it is dissolved and ceases to exist. Special committees are often formed to address particular issues, organize events, or investigate matters that require focused attention outside of the regular operations. Their temporary nature distinguishes them from standing committees, which are permanent and deal with ongoing responsibilities, advisory committees that provide input but do not hold authority, and executive committees, which typically hold significant power within an organization for ongoing oversight.
