"Now wait a minute!" That was Justice Souter, explaining to the Solicitor General, in the case "Hamdan v. Rumsfeld", that he wasn't about to allow the President or Congress prevent the Supreme Court from exercising its Constitutional jurisdiction over habeas corpus.
As Solicitor General Clement said, "I think at least if you're talking about the extension of the writ to enemy combatants held outside the territory of the United States —— "
"Now wait a minute!" Justice Souter interrupted, waving a finger. "The writ is the writ. There are not two writs of habeas corpus, for some cases and for other cases. The rights that may be asserted, the rights that may be vindicated, will vary with the circumstances, but jurisdiction over habeas corpus is jurisdiction over habeas corpus."
Or as Kirk explained in that fine Star Trek episode:
"These words, and the words that follow, were not just written for the Yangs, but for the Kohms as well!"
"But the Kohms--"
"They must apply to everyone, or they mean nothing! Do you understand?"
"I... do not fully understand, one named Kirk... but the Holy Words will be obeyed; I swear it!"
-- Kirk and Cloud William
If only the President would remember that he swore an oath to uphold the Constitution too.
