Eugene Volokh's observations resonate with my superficial impression:
[T]he judge's opinion in today's NSA eavesdropping case seems not just ill-reasoned, but rhetorically ill-conceived. A careful, thoughtful, detailed, studiously calm and impartial-seeming opinion might have swung some higher court judges (and indirectly some Justices, if it comes to that). A seemingly angry, almost partisan-sounding opinion ("[The orders] violate the Separation of Powers ordained by the very Constitution of which this President is a creature," emphasis added, thanks to a caller for pointing this out) is unlikely to sway the other judges — especially when the opinion is rich in generalities, platitudes ("There are no hereditary Kings in America and no powers not created by the Constitution"), and "obviously"'s, and poor in detailed discussion of some of the government's strongest arguments.Also at Volokh Conspiracy, Dale Carpenter is critical of the judge's conclusion that the plaintiffs have standing to sue, and Orin Kerr blasts the Fourth Amendment analysis.
This morning, the Washington Post is really hard on Judge Diggs:
[T]he decision yesterday by a federal district court in Detroit, striking down the NSA's program, is neither careful nor scholarly, and it is hard-hitting only in the sense that a bludgeon is hard-hitting. The angry rhetoric of U.S. District Judge Anna Diggs Taylor will no doubt grab headlines. But as a piece of judicial work -- that is, as a guide to what the law requires and how it either restrains or permits the NSA's program -- her opinion will not be helpful....
The NSA's program, about which many facts are still undisclosed, exists at the nexus of inherent presidential powers, laws purporting to constrict those powers, the constitutional right of the people to be free from unreasonable surveillance, and a broad congressional authorization to use force against al-Qaeda. That authorization, the administration argues, permits the wiretapping notwithstanding existing federal surveillance law; inherent presidential powers, it suggests, allow it to conduct foreign intelligence surveillance on its own authority. You don't have to accept either contention to acknowledge that these are complicated, difficult issues. Judge Taylor devotes a scant few pages to dismissing them, without even discussing key precedents.
It's hard to understand why a judge writing an opinion in such a high-profile case, dealing with such difficult law, would not put immense effort into creating an outward appearance of heavy scholarly effort and pristine neutrality. Does the judge lack the competence to do it? Does the judge have a hot feeling of righteousness and outrage about the case and also think it's good to show it? Perhaps it's some subtle combination of those two things.
UPDATE: The 6th Circuit reverses -- discussed here.
