I'm from Colorado and I know the Romer case well. It was a terrible decision by the Supremes and may be one of the most extreme cases of judicial activism with absolutely NO constitutional or statutory basis in existence. I cannot imagine any explanation that would satisfy me as to why an attorney would give pro-bono time to this case.
BTW, the issue in Romer was solely the constitutionality of a Referendum passed by Colorado voters saying that homosexuals did not get special treatment of any kind under Colorado law. The Supremes invalidated the statute.
If you or anyone has a copy of that, what were the names of the attorneys on the briefs?
