Geneva Conventions and their additional protocols

Despite being signatory to the Conventions, there are some notable and often-criticized U.S. cases involving conduct that would otherwise be prohibited by the Conventions, such as Hamdi v. Rumsfield (2004). In Hamdi, a U.S. citizen was accused of being a member of the Taliban forces on U.S. soil as an "enemy combatant," and was detained by unilateral Executive decision.

The U.S. Supreme Court ruled on the validity of his detention.
