(a) The governing body of a participating municipality by ordinance may authorize the granting of restricted prior service credit to an employee who is a member of the retirement system for service previously performed:
(1) as a full-time, paid employee of the United States, of any public authority or agency created by the United States, of any state or territory of the United States, of any political subdivision of any state of the United States, of any public agency or authority created by a state or territory of the United States, or of an institution of higher education at which the person is commissioned as a campus security personnel employee under § 51.212, Education Code, and for which service the person has not otherwise received credited service in this system, including combined service credit under Chapter 803; or
(2) as an employee of the state or any branch, agency, or subdivision of the state for which the person received credited service under the Employees Retirement System of Texas, the Teacher Retirement System of Texas, the Judicial Retirement System of Texas Plan One, the Judicial Retirement System of Texas Plan Two, the Texas County and District Retirement System, or this retirement system, and the credit for which was canceled because of withdrawal of contributions and has not been reinstated.
(b) Restricted prior service credit may be used only to satisfy length-of-service requirements for retirement eligibility, has no monetary value in computing the annuity payments allowable to the member, and may not be used in other computations, including computation of updated service credits.

(c) A member seeking to establish restricted prior service credit under Subsection (a)(1) must obtain from the official custodian of personnel records of the entity for which the previous service was performed a detailed statement of the service, verified by that official, and file the statement with the clerk or secretary of the participating municipality by which the member is employed. A member seeking to establish restricted prior service credit under Subsection (a)(2) must obtain from the public retirement system in which the canceled service was credited a detailed statement of the service, verified by an official of that retirement system, and file that statement with the clerk or secretary of the participating municipality by which the member is employed.
(d) As soon as practicable after the member has filed the verified statement, the clerk or secretary of the participating municipality authorizing the credit shall examine the statement. If satisfied that the claim is correct, the clerk or secretary shall endorse the statement as approved, file the original in the appropriate files of the granting municipality, and prepare and transmit to the director of the retirement system a certified copy of the approved claim.
(e) On receipt of a certified copy of an approved claim, the retirement system, if satisfied that credit for service claimed under Subsection (a)(1) has not previously been granted the member, or that credit claimed under Subsection (a)(2) previously existed but has been canceled and not reinstated, shall enter the credit in the member’s records.
(f) In this section, “full-time, paid employee” has the meaning assigned “employee” by § 851.001, except that the services do not have to be performed for a municipality.
(g) An ordinance adopted under this section applies to the granting of restricted prior service credit to a member who is or has been an employee of the authorizing municipality at any time on or after the effective date of the ordinance.
