SACRAMENTO (UPI) -- Gov. Pete Wilson signed a homosexual rights bill Friday that bans job discrimination against gays and lesbians, breaking with conservative Republicans who opposed the bill and signing it just one year after he vetoed a similar measure. California becomes the sixth state in the nation to outlaw employment discrimination on the basis of sexual orientation, said Assemblyman Terry Friedman, the Los Angeles Democrat who authored the bill. ``This sends a clear message that California does not tolerate bigotry. I thank the governor for doing the right thing and putting this issue behind us,'' Friedman said. Riots erupted in Los Angeles and San Francisco last year when Wilson vetoed a similar measure, AB101, and enraged California's homosexual community. The new bill, AB2601, provides the same anti-discrimination protections that were contained in the vetoed measure but enforces them through the state labor commissioner instead of the overburdened Fair Employment and Housing Commission. Exempted from the law are employers with four or fewer workers, and church organizations. Wilson said placing discrimination cases under the jurisdiction of the labor commissioner will accelerate the settlement of complaints and cost employers less money to defend themselves against allegations of harassment. The measure, he said, ``provides reasonable and adequate protection against employment discrimination while still meeting the tests of fairness to employers and protection of California's jobs climate.'' Conservative activists, led by the Rev. Lou Sheldon of the Traditional Values Coalition, had urged the Republican governor to veto the bill. ``Gov. Wilson has just signed a law that will socially engineer a new status for any person who seeks special legal protection based on that individual's chosen form of sexual expression,'' Sheldon said in a telephone interview. Sheldon said he is considering mounting a legal challenge or ballot campaign to repeal the law. He predicted that Wilson's decision to sign the bill may impact the upcoming elections by prompting some conservative activists to stop working for moderate Republican candidates. ``It diverts energy,'' Sheldon said. ``It's going to drain conservatives.'' Homosexual groups estimate there are up to 6 million gays and lesbians in California who are now guaranteed protection against job discrimination. ``If you are a person working in a job and you face arbitrary discrimination because you are gay and lesbian, you now have a place to go.'' said Laurie McBride, executive director of the Lobby for Individual Freedom and Equality, which worked to pass the bill. When Wilson vetoed AB101 last year, he argued that homosexuals were already protected from job discrimination under a broad interpretation of the state's labor code. Wilson ordered his labor commissioner, Victoria Bradshaw, to accept discrimination complaints against homosexuals several weeks later after a state appeal court upheld that interpretation of the law. Since then, 87 gays and lesbians have filed discrimination complaints with Bradshaw's office. The parties have settled in 10 of the cases, and 38 are under investigation, spokesman John Duncan said. Four complaints by homosexuals were found valid, and 17 were adjudicated in favor of the employer, Duncan said. The new law codifies existing Wilson administration policy and is far more limited than a gay rights plank in a sweeping civil rights bill by Assembly Speaker Willie Brown, D-San Francisco, that would also outlaw housing discrimination against homosexuals. Wilson is expected to veto Brown's bill this weekend. Civil rights activists said the governor is trying to deflect criticism of the veto by signing Friedman's measure one day after he narrowly approved a narrowly drawn package of civil rights measures. ``So many of the protections that other minorities get are missing out of the bill. It's just basically just a sop bill. We don't think it is enough,'' said Dawn Levy, a lesbian member of ACT-UP in Los Angeles. States with similar anti-discrimination laws include Massachussets, Connecticut, Hawaii, Vermont and Wisconsin.
