Supreme Court: Fourth Amendment Protects Against Electronic Monitoring… Sometimes.
In Grady v. North Carolina, the United States Supreme Court unanimously decided that the government conducts a “search” implicating the protection of the Fourth Amendment when it monitors someone’s movements electronically without their consent. This ruling may have some implications for the government’s use of electronic surveillance techniques, but ultimately the reasoning for the decision is fairly narrow. It seems unlikely to significantly affect, for instance, the various widely reported NSA programs that monitor information about the American public.
Grady is an unsigned summary decision, issued without full briefing or oral argument, indicating that the Court viewed it as a minor clarification of existing law that caused no controversy among the Justices. Torrey Dale Grady is a twice-convicted sex offender who has served the sentences for his crimes. Under applicable North Carolina law, after Grady was released, the State obtained a civil court order that, because he is considered a recidivist sex offender, he must wear a GPS monitoring ankle bracelet (or similar monitoring device) for the rest of his life. Grady challenged this monitoring requirement as an unreasonable search under the Fourth Amendment. The North Carolina state courts determined that it was not a search, and so the Fourth Amendment was not implicated.
