The Maryland Court of Appeals, the state’s highest court, has ruled that same-sex couples who married in other states can obtain divorces in Maryland. According to the Baltimore Sun, the unanimous ruling stemmed from a 2010 case in Prince George’s County where a judge refused to grant a divorce to a couple who had married in California, which led to an appeal. Gov. Martin O’Malley (D) signed legislation legalizing same-sex marriage in Maryland earlier this year, but opponents are seeking a November referendum to overturn it. Assuming it is not overturned, the law will only take effect in January, 2013.
