Pleased to share my latest in the Penn Law Rev. online on FISA! I suggest expanding appellate review of FISA decisions through modest tweaks to the FISA amicus curiae system. Doing so would expand procedural protections while avoiding legal pitfalls of other proposed reforms.
Ahead of FISA's pending expiration, the Penn Law Review Online is pleased to publish @axsobel's "Procedural Protections in a Secret Court: FISA Amici and Expanding Appellate Review of FISA Decisions." pennlawreview.com/online/

"Fourth Amendment doctrine has repeatedly struggled to keep pace with the novel privacy issues that attend evolving surveillance technology." @axsobel argues that the 4th A doesn’t actually prevent the gov't from purchasing personal data from data brokers. lawfaremedia.org/article/dat…

Elated that my Note on data brokers and the Fourth Amendment won @YaleLawSch’s Burton H. Brody Prize in Constitutional Law and the Edward D. Robbins Memorial Prize for best student publication appearing outside YLJ. It is officially out in YLPR — check it out here!
In his new Note in YLPR, Aaron X. Sobel (@axsobel) argues that the Fourth Amendment does not regulate government purchases of geolocation data and urges Congress to pass legislation to regulate private sales of such data. Read "End-Running Warrants" here: yalelawandpolicy.org/end-run…

With the 4th Amendment is Not For Sale Act (FAINFSA) returning to Congress, see my latest @YaleLawPolicyR! I argue gov't purchases from data brokers are not "state action," and so not protected by the Constitution. But Congress can do better than FAINFSA: papers.ssrn.com/sol3/papers.…

When Congress sues the executive branch for waging illegal wars, courts dismiss their suits for presenting a political question. But Congress can overcome this barrier and recover a role for the courts. My latest w/ Prof @oonahathaway & Mike Sullivan: justsecurity.org/86880/recov…

Recovering a role for the courts in decisions to wage war: Congress could act to limit courts’ ability to dismiss cases before they reach the merits. From @axsobel, Michael Sullivan and @oonahathaway: justsecurity.org/86880/recov…
