Government Code §75.002

(a) A retiree who makes an election under Section 75.001 is, with the retiree's consent to each assignment, subject to assignment: (1) by the chief justice of the supreme court to sit on any court of the state of the same or lesser dignity as that on which the person sat before retirement; (2) by the presiding judge of the court of criminal appeals to sit as a commissioner of that court; and (3) if the retiree's last judicial office before retirement was judge of a district or statutory county court, by the presiding judge of an administrative judicial region to sit on a district or statutory county court in that administrative region or, on request of the presiding judge of another administrative judicial region, to that administrative region. (b) In addition to an assignment under Section 74.003 and Subsection (a)(1), the chief justice of the supreme court may assign a retiree whose last judicial office before retirement was justice or judge of the supreme court, the court of criminal appeals, or a court of appeals to the administrative judicial region in which the retiree resides for reassignment by the presiding judge of that region to a district or statutory county court in the region. The reassignment by a presiding judge is subject to the requirements of Section 74.055 . The assignment by the chief justice of a retiree to the administrative region of the retiree's residence continues only during the period for which the retiree has certified a willingness to serve under Section 74.0551 . (c) A retiree assigned under this subchapter has all the powers of a judge of the court to which the retiree has been assigned.
