Recap of Supreme Court Decisions in Carpenter and Currier

As we mourn Justice Kennedy’s retirement, Sentencing Resource Counsel Sissy Phleger has graciously allowed us to post her summaries of the Supreme Court’s recent decisions in Carpenter v. United States (opinion available here) and Currier v. Virginia (opinion available here):

First, in the eagerly-anticipated Carpenter v. United States, the Court held that the government’s acquisition of Mr. Carpenter’s cellphone location records was a Fourth Amendment search. Roberts wrote for the majority, joined by Kagan, Breyer, Sotomayor, and Ginsburg. All the dissenters filed separate opinions (and variously join in each other’s). While the majority opinion is at pains to confine its impact, this is a great win with potential implications far beyond its specific circumstances.

Mr. Carpenter had challenged the use of warantlessly-obtained historical cell-site location records used to convict him of a string of armed robberies. He argued that the records constituted a search, and thus required …

Second Circuit Updates – August 2, 2016

Yesterday, in United States v. Carabello, 12-3839, the Second Circuit held that exigent circumstances justified the warrantless “pinging” of a defendant’s cell phone.  Law enforcement officers searching for Caraballo in connection with the execution-style murder of one of his drug associates asked Sprint to utilize its emergency procedures to “ping” Caraballo’s cell phones so that the phones, and hopefully Caraballo, could be located through the triangulation of signals given off by the phones in response to the “pings” sent by Sprint.

The Court affirmed the district court’s denial of suppression, holding that it was not clearly erroneous for the district court to find that exigent circumstances justified the warrantless pinging.

The Court reviewed the exigency factors laid out in Dorman v. United States, 435 F.2d 385 (D.C. Cir. 1970)(en banc) and United States v. MacDonald, 916 F.2d 766, 769-70 (2d Cir. 1990)(en banc) and considered these factors …
