Supreme Court to take up DOMA and Prop. 8 cases

This just in:

The U.S. Supreme Court will take up the issue of gay marriage for the first time, agreeing to rule on a California ballot measure banning the practice and a federal law defining marriage as solely an opposite-sex union.

The cases, which the court will decide by June, loom as a potential turning point on one of the country's most divisive issues. High court review comes as the gay-marriage movement is showing unprecedented momentum, winning victories at the polls in four states this year.

The California dispute will address whether gay marriage is legal in the most populous U.S. state, home to more than 37 million people. The case also gives the justices a chance to go much further and tackle the biggest issue: whether the Constitution guarantees same-sex marriage rights nationwide. [...]

In addition to the California case, the justices today said they will review the U.S. Defense of Marriage Act, a 1996 law that two federal appeals courts said impermissibly treats legally married gay couples differently than heterosexual couples. DOMA, as the measure is known, blocks gays from claiming the same federal tax breaks and other marriage benefits that opposite-sex spouses enjoy.

Stay tuned for a more in-depth look at these cases and potential outcomes for both.
