La. R.S. 11:1303

The board of trustees may take such actions as it deems necessary or appropriate to provide for the joint administration of the retirement system and the Louisiana State Employees' Retirement System; however, no action shall be taken which would impair the integrity of the board of trustees of each of the systems or the integrity of the funds and investments of each of the systems. The boards may, pursuant to the authority herein, appoint the same secretary-treasurer or secretary-manager, any other provisions of law to the contrary notwithstanding. Funds appropriated for the administration of each system shall be used for such purpose and in the category of expenditures appropriated but otherwise may be transferred to accomplish the purposes of this Section subject to the approval by the legislature, the Legislative Budget Committee, or its successor, or the division of administration or its commissioner. The board shall prepare and submit to the Joint Legislative Committee on the Budget an annual budget for estimated costs of operating the system for each succeeding fiscal year. This budget shall be subject to approval by the Joint Legislative Committee on the Budget.
