September 5, 2025 | SIBTF.org — After passing the California Assembly earlier this year, AB 1329 has moved into the State Senate, where lawmakers are now considering major reforms to the Subsequent Injuries Benefits Trust Fund (SIBTF). The bill introduces several changes, including tightened eligibility criteria for applicants, the creation of a medical evaluator database, and new trustee appointment guidelines aimed at improving oversight.
Why AB 1329 Matters for Injured Workers
The SIBTF program, originally designed to protect employees with pre-existing disabilities who sustain new workplace injuries, has faced mounting pressure due to significant delays and rising liabilities. With applicants waiting years for resolution, legislators argue that AB 1329 could streamline processes, improve medical review accuracy, and strengthen accountability within the fund’s administration.
Potential Impacts Across California’s Workers’ Compensation System
If enacted, the reforms may reduce case backlogs and bring more consistency in how claims are evaluated. Employers and insurers are closely monitoring the bill’s progress, as changes in eligibility standards could directly affect claim costs. At the same time, advocacy groups caution that while oversight improvements are necessary, reforms must not restrict access for workers who rely on SIBTF for long-term financial support.
Next Steps in the Legislative Process
The Senate committee will continue hearings on AB 1329 throughout the summer session. Stakeholders expect a floor vote later this year, potentially setting the stage for sweeping changes to how SIBTF claims are processed and funded in California.
