Relating to participation in, administration of, contributions to, and benefits under the Texas Municipal Retirement System.

SB 2436 amends Texas law governing the Texas Municipal Retirement System to clarify legal venue for disputes involving the system, requiring all related lawsuits to be filed in Travis County. It updates procedures for municipalities joining the system, mandates actuarial certification before adopting certain benefit ordinances, and establishes rules for employees to reinstate canceled retirement credits. The bill directly affects Texas municipalities participating in the retirement system and their employees who may seek to restore prior service credits. Key changes include standardized venue requirements, new actuarial review thresholds for benefit adjustments, and specific conditions for reestablishing credited service.
