La. Consolidated Public Retirement § 11:734
Notwithstanding any other provision of law to the contrary, any member of the legislature who is not employed as a teacher but is a member of this system by virtue of having been so employed, may, at his option, contribute to the system the percentage set by R.S. 11:62(11)(c) of his legislative salary and expense allowance, plus the four percent that he contributes as a member of the legislature in accordance with R.S. 24:36. If he elects to so contribute, the house of the legislature of which he is a member shall contribute to the system a percentage of his legislative salary and expense allowance which is equal to the employer contribution rate for the Teachers' Retirement System. If he elects to so contribute, he shall receive credit in the system for one year of teaching service for each year of legislative service rendered. Upon the member paying the employee contributions to the system which he could have paid if this Section had been in effect, plus interest at the board-approved actuarial valuation rate thereon from the date of service until paid, the provisions of this Section shall be applicable with respect to legislative service rendered prior to October 1, 1976. If the member elects to contribute to such prior service, the appropriate house of the legislature shall contribute to the system the employer contributions which would have been paid if this Section had been in effect and the member had elected to contribute the employee contributions, plus interest at the board-approved actuarial valuation rate thereon from date of service until paid.
