Hamdan (and Sanchez-Llamas)

In case you were wondering how the Hamdan decision might relate to international economic law, and how the Supreme Court came to apply the Geneva Conventions, there is a nice post by Rosa Brooks at the Georgetown faculty blog explaining how Hamdan approaches international law.  Basically, the relevant portions of the Geneva Conventions (common article 3) are specifically incorporated by reference in U.S. domestic law, and become judicially applicable (at least) to that extent.
