2(c)(iii) The Government’s sovereignty-based test raises troubling separation-of-powers concerns, which are illustrated by Guantanamo’s political history. Although the United States has maintained complete and uninterrupted control of Guantanamo for over 100 years, the Government’s view is that the Constitution has no effect there, at least as to noncitizens, because the United States disclaimed formal sovereignty in its 1903 lease with Cuba. The Nation’s basic charter cannot be contracted away like this. The Constitution grants Congress and the President the power to acquire, dispose of, and govern territory, not the power to decide when and where its terms apply. To hold that the political branches may switch the Constitution on or off at will would lead to a regime in which they, not this Court, say “what the law is.”
