This afternoon, Chief U.S. District Judge Vaughn Walker will publish his decision on whether to uphold or overturn the California voter-approved ban known as Proposition 8 (or the California Marriage Protection Act) that would insert language into the state constitution saying that "only marriage between a man and a woman is valid or recognized in California." [Update: Proposition 8 was just overturned.] Walker's ruling is one of a number of recent decisions made by voters and governments around the world affecting the ability of same-sex couples to marry legally. Around the U.S., several states are challenging the 1996 Defense of Marriage act, both Washington DC and Mexico City legalized same-sex weddings last March, and on July 15th, Argentina became the first Latin American country to recognize same-sex marriage. Collected here are a handful of recent photos of couples in several countries, all in the process of getting married.
