revise certain requirements for contesting actions of the South Dakota Retirement System.

SB 51 revises the process for individuals to contest decisions made by the South Dakota Retirement System. It changes the deadline for requesting a contested case hearing from 30 days to 60 days after receiving a decision, requiring written requests sent by certified mail to specify the contested portion and the alleged factual or legal error. The bill also clarifies that requests postmarked within 60 days count as timely received, and failure to meet this deadline bars court review. This directly affects retirees or beneficiaries who disagree with Retirement System determinations about their benefits. The changes streamline the appeal timeline and documentation requirements without altering benefit eligibility or amounts.
