Treaties, which are described in the US Constitution.

Jacques and Pierre achieved wedded bliss in Montreal, they moved to Colorad. Voila, they are not married in the eyes of Colorado or the US of A.

But I don't understand your point. The states are bound by the Constitution through full faith and credit. Treaties made with other nations, are Constitutional but a whole other ball of wax. No relation to each other.

My only point that the US government and the US courts pick and choose which marriages are valid all the time, at least in the matter of with foreign marriages.

Why do US courts accept a marriage of two hetero people from Peru, but not a marriage of two gay people from Denmark? Do these treaties explicitaly exclude gay marriage or polygamist marriage?

I don't know the answer, I was wondering if you knew why.

As far as the Full Faith and Credit clause, why is that a Florida concealed carry permit is not accepted in Massachusetts? Who determines which state acts are valid nationwide, and which state acts are valid only inside a state?
