Texas Government Code - GOV'T § 812.203. Benefits Affected

(a) If a retiree takes the oath for a position included in the elected class of membership, the retirement system shall suspend annuity payments to the person for service that was credited in that class, until the person no longer holds that position.

(b) Time during which annuity payments are suspended as provided by this section does not reduce the number of months payments are to be made under an optional benefit selection providing for a specific amount of benefits for a guaranteed number of months after retirement.

(c) If a member who originally retired with service credited at the time of that retirement only in the elected class of membership again retires, the person at the time of subsequent retirement may select an annuity based on service in the elected class as if the person were retiring for the first time.  If the person selects an annuity under Section 814.108(c)(3) or (c)(4), the retirement system shall reduce the number of months of guaranteed payment by the number of months for which an annuity was paid under the person's original retirement.
