Josef Altstötter had the misfortune, because of his name, to be the first defendant listed among the 16. He was not the most important or the worst, although he was one of the 10 who were in fact convicted (4 were acquitted, one committed suicide, and there was one mistrial). He was a well-regarded member of society and a high-ranking lawyer. In 1943 he joined the Reich Ministry of Justice in Berlin, where he served as a Ministerialdirektor, the chief of the civil-law-and-procedure division. He became a member of the SS in 1937. The U.S. Military Tribunal found him guilty of membership in that criminal organization—with knowledge of its criminal acts—and sentenced him to five years in prison, which he served in full. He returned to legal practice in Nuremberg and died in 1979. Ludwig Altstötter had all the relevant documents, and he generously invited me to go over them with him in Nuremberg.

I took Ludwig to the most striking passage in the tribunal’s judgment. “He gave his name as a soldier and a jurist of note and so helped to cloak the shameful deeds of that organisation from the eyes of the German people.” The tribunal convicted Altstötter largely on the basis of two letters. Ludwig went to the piles on the table and pulled out fading copies of the originals. The first, dated May 3, 1944, was from the chief of the SS intelligence service to Ludwig’s father, asking him to intervene with the regional court of Vienna and stop it from ordering the transfer of Jews from the concentration camp at Theresienstadt back to Vienna to appear as witnesses in court hearings. The second letter was Altstötter’s response, a month later, to the president of the court in Vienna. “For security reasons,” he wrote, “these requests cannot be granted.” The U.S. Military Tribunal proceeded on the basis that Altstötter would have known what the concentration camps were for.

The words “security reasons” reminded me of remarks by Jim Haynes at the press conference with Gonzales: “Military necessity can sometimes allow … warfare to be conducted in ways that might infringe on the otherwise applicable articles of the Convention.” Haynes provided no legal authority for that proposition, and none exists. The minimum rights of detainees guaranteed by Geneva and the torture convention can never be overridden by claims of security or other military necessity. That is their whole purpose.

Mohammed al-Qahtani is among the first six detainees scheduled to go on trial for complicity in the 9/11 attacks; the Bush administration has announced that it will seek the death penalty. Last month, President Bush vetoed a bill that would have outlawed the use by the C.I.A. of the techniques set out in the Haynes Memo and used on al-Qahtani. Whatever he may have done, Mohammed al-Qahtani was entitled to the protections afforded by international law, including Geneva and the torture convention. His interrogation violated those conventions. There can be no doubt that he was treated cruelly and degraded, that the standards of Common Article 3 were violated, and that his treatment amounts to a war crime. If he suffered the degree of severe mental distress prohibited by the torture convention, then his treatment crosses the line into outright torture. These acts resulted from a policy decision made right at the top, not simply from ground-level requests in Guantánamo, and they were supported by legal advice from the president’s own circle.

Those responsible for the interrogation of Detainee 063 face a real risk of investigation if they set foot outside the United States. Article 4 of the torture convention criminalizes “complicity” or “participation” in torture, and the same principle governs violations of Common Article 3.
