DOMA Challenged on First Amendment Grounds

Charles Merrill has filed a lawsuit with the Federal Tax Court claiming that the Defense of Marriage Act violates the Establishment Clause of the First Amendment to the U.S. Constitution. This comes to us from the Tax Prof. Blog.

The Establishment Clause is an interesting choice. I would have picked the Equal Protection Clause, since restricting marriage to a man and a woman would seem to deny same sex couples a fundamental right (to take advantage of certain tax laws such as the unlimited marital deduction). But what do I know?

I will try to follow this as best I can.
