There are quite a few reports in the mainstream media saying that part of the USA PATRIOT act has been struck down as unconstitutional.

Orin Kerr, who has actually read the opinion, suggests the reports are misinformed. It was a provision of the Electronic Communications Privacy Act 1986 which was actually held to be unconstitutional. Orin is not too impressed:

"Mainstream Media Ruled Unconstitutional:
No, not really. But is it too much to ask that when the mainstream media reports on court decisions that they properly identify the law that is struck down and the Administration that is rebuked? Apparently it is, at least if the Thursday morning papers are any guide."
