In 2008, two of these groups moved to qualify ballot initiatives to amend the California Constitution on the November 2008 ballot. One qualified as Proposition 8. The amendment eliminates the right of same-sex couples to marry, but does not repeal any rights granted to domestic partnerships and registration for domestic partnerships remains legal in California. In late 2008, Proposition 8 was passed by the voters, in 2009, the legality of Proposition 8 was upheld by the California Supreme Court in "Strauss v. Horton" holding that same-sex couples have all the rights of heterosexual couples, except the right to the "designation" of marriage and that such a holding does not violate California's privacy, equal protection, or due process laws; the "In re Marriage Cases" still apply. Proposition 8 then was challenged in federal court on August 4, 2010 in the "Perry v. Schwarzenegger" trial, as it was found to have violated the Due Process and Equal Protection Clauses of the 14th Amendment of the Federal Constitution.
