California’s Supreme Court Published a Decision Today in 2012 “Vested Rights” Lawsuit


The decision has been published by the California Supreme Court in litigation that started in 2012 over changes to the state pension law affecting “legacy members” of ACERA and two other county retirement systems. 

Legacy members generally are those who have entry dates into ACERA membership prior to January 1, 2013, which was the effective date of the California Public Employees’ Pension Reform Act (PEPRA). This lawsuit relates only to legacy members who retired on or after January 1, 2013.

The publishing of the decision followed after the Court’s hearing of oral arguments in the case on May 5, 2020. ACERA is currently analyzing the decision and will provide a summary of it when our analysis is complete. Please check this news page later for further details. A copy of the decision is below:
