A member who makes affidavit that he has permanently terminated his employment in state-supported public education in Texas but who is so employed or who contracts for such employment before he receives the refund of his account shall not be entitled to the refund. If the refund is made by error or because the retirement system is not aware of the continued employment, necessary steps will be taken to secure the redeposit of the withdrawn account. No benefits will be paid until this withdrawn account is returned to the retirement system.
