Louisiana Revised Statutes Tit. 11, § 502.4. Limitations; unclassified employees

Any eligible employee who elects to participate in this optional retirement plan shall always be ineligible for membership in the defined benefit plan, even if he is employed in a position covered by the defined benefit plan and shall only be entitled to those benefits set out in this Subpart. If any such optional retirement plan participant assumes a new position covered by the retirement plan, then he shall continue to participate in the optional retirement plan, notwithstanding the provisions of R.S. 11:417. If any such optional retirement plan participant assumes a new position in state service not covered by the defined benefit plan, he must at that time begin membership in the retirement system which provides benefits for that position in state service.
