On Monday, the Second Circuit handed down a very important decision on standing to challenge secret surveillance programs in Amnesty International USA v. Clapper. The decision, by Judge Gerard Lynch and joined by Judges Calabresi and Sack, offers a very easy way for plaintiffs to have Article III standing to challenge secret surveillance statutes. The opinion strikes me as puzzling, however, and it appears to be in conflict with other Courts of Appeals cases on standing to challenge surveillance regimes. I suspect Supreme Court review is a serious possibility.
