Thanks to Will’s excellent post below, I now think I was wrong before in my earlier approach to Maynard. My sense now is that the correct approach is to say that the Supreme Court didn’t reach the Maynard question of whether GPS tracking is a search under Katz. As a result, there is still a circuit split on the issue that Jones left unresolved. This means that Maynard is binding appellate precedent in the DC Circuit, and the cases on the other side of the split are binding in those other circuits.
