Louisiana Revised Statutes Tit. 11, § 1936. Vesting

A. A member who withdraws from active service on or after the revision date prior to becoming eligible for retirement, having at least seven years of creditable service, and having received no refund of his accumulated contributions, shall be entitled to receive a retirement allowance to commence on his earliest normal retirement date.

B. A member who withdrew from active service prior to the revision date, and having received no refund of his accumulated contributions, shall be entitled to receive a vested retirement allowance according to the statutes in effect at time of such withdrawal, provided he was eligible therefor.

C. Should a vested termination member return to active employment, he shall become a member and shall contribute at the current rate; but should such member return to employment after attaining the age of fifty, his benefit upon retirement shall not exceed the sum of the benefit for which he would have been eligible based on the previously credited service and the benefit for which he would be eligible based on the service since his latest employment, had he enrolled at that time as a new entrant.
