SAN FRANCISCO AP – Even as same-sex couples across California begin making plans to tie the knot, opponents are redoubling their efforts to make sure wedding bells never again ring for gay couples in the nation’s most populous state.

A conservative group said it would ask California’s Supreme Court to postpone putting its Thursday decision legalizing gay marriage into effect until after the fall election. That’s when voters will likely have a chance to weigh in on a proposed amendment to California’s constitution that would bar same-sex couples from getting married.
