“Congress appears clearly to have intended to — and did — establish the exclusive means for foreign intelligence activities to be conducted,” the judge wrote. “Whatever power the executive may otherwise have had in this regard, FISA limits the power of the executive branch to conduct such activities and it limits the executive branch’s authority to assert the state secrets privilege in response to challenges to the legality of its foreign intelligence surveillance activities.”
