The church denomination that Obama belonged to for 20 years has issued a legal challenge to California's Prop 8:
"The General Synod of the United Church of Christ, as well as the UCC's Southern California – Nevada Conference and Northern California – Nevada Conference, joined other religious bodies in filing litigation on Nov. 17 that argues that Proposition 8 amounted to a constitutional "revision" because it took away a fundamental civil right. In California, a constitutional revision, unlike an amendment, requires legislative authorization in addition to voter approval.
"California's constitutional right of equal protection is sacrosanct," the legal challenge reads in its introduction. "Not even the electorate can take it away selectively – at least not without a two-thirds vote of the legislature or a constitutional convention. This writ petition seeks to enforce that basic principle.""
