Perry v. Schwarzenegger was a case in a federal US District Court in San Francisco. At issue was whether California's Prop 8, which defined marriage as between a man and a woman, and was passed by a majority of California votes in November 2008, violated the US Constitution's 14th amendment. The trial court ruled that the measure was unconstitutional on August 4, 2010. Conservatives then tried to appeal the case.
It reached the Supreme Court under the name Hollingsworth v. Perry. In a 5-4 decision, the Supreme Court ruled that the opponents of homosexual marriage did not have Article III standing to appeal the adverse federal court ruling when California refused to do so. Chief Justice John Roberts wrote the majority opinion, and was joined by Elena Kagan, Ruth Bader Ginsburg, Stephen Breyer, and shockingly Antonin Scalia. Anthony Kennedy, who usually sided with the homosexual agenda, wrote the dissent. He was joined by Samuel Alito, Clarence Thomas, and interestingly Sonia Sotomayor.
