In a major case involving gay rights at CalPERS, the nation's largest public pension fund has been ordered to offer its long-term care insurance program to same-sex partners of California workers. A federal judge in Oakland struck down portions of the federal Defense of Marriage Act that have prevented the California Public Employees' Retirement System from extending the insurance to gay spouses and domestic partners. In a ruling released Thursday, U.S. District Judge Claudia Wilken said the ban served no "legitimate governmental interest" and was apparently "motivated by anti-gay animus."
