Catholic school teachers, students, parents and alumni turned out at an Assembly hearing in San Francisco to blast the Catholic archdiocese’s plans to change teachers contracts and enforce a “morality clause” that describes homosexuality as “gravely evil”. State lawmakers held the hearing to gather information in the wake of a US Supreme Court ruling that says ministers are not covered by anti-discrimination employment laws, an exception that could include teachers at church-based schools. Christopher Martinez reports from San Francisco.
