DETROIT -

A Michigan couple has won their fight against the state's voter-approved ban on same-sex marriage.

Judge Bernard Friedman gave his decision Friday, two weeks after the couple's trial against the ban started. Friedman's ruling says the ban is "unconstitutional because they violate the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution."

In 2004, the state of Michigan enacted the Defense of Marriage Act after it was passed by 59 percent of voters. The act argues that children benefit from living in homes of heterosexual couples.

April DeBoer and Jayne Rowse sued the state of Michigan's federal court in an effort to overturn the state's ban on joint adoptions by same-sex couples. Friedman invited them to challenge the state's ban on same-sex marriage. They refiled the lawsuit and went to trial against the state's ban on gay marriage.
