Why is Gay marriage an issue for the Supreme court?????

6. Full faith and credit clause.

Article IV, Section 1 of the constitution reads as follows (emphasis mine):

Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect thereof.

Since marriage, in the civil sense, is a judicial proceeding, a couple married in one state must be recognized as married in all states.

The precedent for this is Loving v. VA.

For DOMA to be upheld and for any state to have a right to ignore a couple's marriage in another state, Loving v. VA must be overturned, meaning miscegeny laws would come back into effect.
