“Parking enforcement officers in Saginaw, Michigan, who use chalk to mark the tires of cars to track how long they have been parked are violating the constitution, a federal appeals court ruled Monday.” [Amanda Robert, ABA Journal] In particular, the court found that chalking was a trespass and a search meant to obtain information that was not reasonable under a probable-cause or community-caretaker standard, nor under an exception allowing orderly regulation of road traffic, since in the court’s view it was aimed primarily at obtaining revenue rather than mitigating public hazard.

Update, from Orin Kerr: “The Sixth Circuit has issued an amended opinion in the chalking case clarifying the limited scope of its holding.” Quoting the amended opinion: “Taking the allegations in Taylor’s complaint as true, we hold that chalking is a search under the Fourth Amendment, specifically under the Supreme Court’s decision in Jones. This does not mean, however, that chalking violates the Fourth Amendment. Rather, we hold, based on the pleading stage of this litigation, that two exceptions to the warrant requirement — the ‘community caretaking’ exception and the motor-vehicle exception — do not apply here. Our holding extends no further than this. When the record in this case moves beyond the pleadings stage, the City is, of course, free to argue anew that one or both of those exceptions do apply, or that some other exception to the warrant requirement might apply.”
