The State of Texas is geographically divided into disciplinary districts that are coextensive with the districts of elected Directors of the State Bar. One or more Committee subdistricts shall be delineated by the Board within each such District. From time to time, if the Commission deems it useful for the efficient operation of the disciplinary system, it shall recommend to the Board that a redelineation be made of one or more subdistricts within a District. All Committees within a single disciplinary district have concurrent authority within the District but once a matter has been assigned to a Committee, that Committee has dominant jurisdiction, absent a transfer.
