Habeas corpus: An Old Battle Resumes at the Supreme Court - The New York Times

So last year...

No Freeman shall be taken or imprisoned, or be disseized of his Freehold, or Liberties, or free Customs, or be outlawed, or exiled, or any other wise destroyed; nor will We not pass upon him, nor condemn him, but by lawful judgment of his Peers, or by the Law of the land.Magna Carta 1215

But immigrants aren't Freemen. So goodbye Magna Carta.

The war on Boumediene is not ancient history. In his widely noticed speech to the Federalist Society in November, Attorney General William P. Barr took direct aim at the decision, referring to it as the climax of “the most blatant and consequential usurpation of executive power in our history.” According to the attorney general, the Supreme Court, in its series of Guantánamo cases, “set itself up as the ultimate arbiter and superintendent of military decisions inherent in prosecuting a military conflict — decisions that lie at the very core of the president’s discretion as commander in chief.”

In its decision last March, a panel of the United States Court of Appeals for the Ninth Circuit held the jurisdiction-stripping provision of the law unconstitutional. “Boumediene is our starting point,” the appeals court wrote. It held that like the Military Commissions Act that the Supreme Court invalidated in that case, the immigration law amounted to an unconstitutional “suspension” of habeas corpus. The reference is to Article I, Section 9, Clause 2 of the Constitution, the Suspension Clause, which provides: “The privilege of the writ of habeas corpus shall not be suspended, unless when in cases of rebellion or invasion the public safety may require it.”

In the government’s petition to the Supreme Court, which the justices granted in October, Solicitor General Noel Francisco argued that Boumediene was “fundamentally different” from this case, because while the Guantánamo detainees were seeking release from custody so they could return home, Mr. Thuraissigiam is already free to return home but is trying to stay: “He would be removed to and released in Sri Lanka forthwith absent his habeas petition.”
