Title 20 - Employees' Benefits
If the employee or the employee's family are disadvantaged in any way by a recomputation of a PIA to consider additional earnings, a request can be made to waive or give up the right to the recomputation. Such a request must be in writing and be made by every entitled family member. A request for waiver of a recomputation applies only to that recomputation for which the request is made.
