Post-Carpenter, What's the Status of the 3rd-Party Doctrine?
Orin Kerr's same-day take on the status of the third-party doctrine can be found here (question #9)
- It lives, but there is an equilibrium-adjustment cap on it. The old understanding was that the third-party doctrine is a bright-line rule: When you voluntarily disclose information to someone, whether to an undercover officer or a business you're working with, you don't have Fourth Amendment rights in the recipient's copy of that information. Chief Justice Roberts says that the third-party doctrine is more limited than that.
- As I read him, the Chief seems to be saying that there is an equilibrium-adjustment limit on the third-party doctrine. Once the third-party doctrine starts to give the government massive new powers, the third-party doctrine may no longer apply. Here's the key passage:
- "There is a world of difference between the limited types of personal information addressed in Smith and Miller and the exhaustive chronicle of location information casually collected by wireless carriers today.The Government thus is not asking for a straightforward application of the third-party doctrine, but instead a significant extension of it to a distinct category of information."
As many of you may know, I've written about the limitations on the third-party doctrine under the Oregon Constitution ever since St v Ghim came out. OCDLA had a presentation on Ghim at the Winter Conference 2017, which is looking rather prescient right now.
There is a lot for defense attorneys to work with now, under both Constitutions.
