1. They can be narrowed. "Gathering data from all customers regarding where and where they called from and who they called is fundamentally different under the 4th Amendment than what was decided under Smith."
2. They can be expanded, "Cell site location information is no different than what a pen register collects under the Constitution."
3. They can be overruled by the Supreme Court ("We hold we were wrong when we decided Smith v. Maryland.") This is the last choice for obvious practical reasons, and it involves more scrutiny.
I don't think this will cause the third party doctrine to be reconsidered as it was decided in the past (in the context of narrow investigations). I think it is far more likely that courts (from circuit courts to the Supreme Court) will merely hold that it is Constitutionally different to do this to everyone without individualized suspicion than to do it to a specific individual already under investigation, just as it would be Constitutionally different to issue a search warrant for all apartments in a high-rise apartment building than it is to issue a search warrant on an individual's home. I don't think California Bankers Association will be overruled either and if they feel compelled to differentiate, they may say that rules do not require routine disclosure of all financial records, only the few big ones.
Thanks for your comments. I appreciate the tone and research you have added. I actually am a lawyer, though a bit rusty on con law, having spent the past 10 years working in tech after a stint as a federal criminal defense attorney where the fourth amendment was one of my main weapons.
With that out of the way, the best discussion of this topic and all the nuances that I've found is a "debate" between two law professors on the initial issue I raised: the third party doctrine.
Like you, they argue what they think the law should be. In contrast, I'm stating simply what it is.
I stand by my original assertion that Rackspace is not bound by the fourth amendment. This may be a technical point but an important one. Shaky though Smith v. Maryland may be, it remains the law of the land. Users have no "reasonable expectation of privacy" in data they store on Rackspace servers.
I guess my viewpoint is that I am not sure that it is clear what the law is. Smith seems pretty clear as does California Bankers Association, and when you take these two cases together, then dragnet surveillance would not be under different rules and Smith would govern this.
However I am not certain that this is the only way to look at the existing precedents. If you look at Rhenquist's majority opinion in Knotts, for example, he is quite clear that whether widescale tracking is under the same rules is not a question the court was deciding. Knotts is important for the Verizon order because I think one can argue that beeper cases are closer to cell site location information (also disclosed under the Verizon order) than they are to pen registers.
Since Knotts leaves explicitly open the question of whether widespread location tracking is under different rules, I think it is premature to just say that Smith and California Bankers Association control on their face. Additionally it is anything but clear what the Supreme Court said about this in Jones v. United States because it isn't clear how to count the votes. I would argue that Sotomayor and Alito do not control, but the fact that you have 5 justices clearly edgy about such things in their separate opinions (Alito concurring in judgement joined by Breyer, Ginsberg, and Kagan, Sotomayor concurring with Scalia but endorsing Alito's views).
If I had to say what the law is in this case I would say this:
The law is currently unclear. There is, however, a bunch of Supreme Court opinion which seems to give permission to circuit courts to figure this issue out.
Edit: I would also like to point out that the third circuit has held that historical cell site location information is at least potentially protected under the 4th Amendment, and that magistrates have the power to deny ordering disclosure of such on the basis of such 4th Amendment concerns. I don't think the Third Circuit could do this if it was clearly established that these third party business records were outside the purview of the 4th Amendment.
Precedence can be handled a few ways:
1. They can be narrowed. "Gathering data from all customers regarding where and where they called from and who they called is fundamentally different under the 4th Amendment than what was decided under Smith."
2. They can be expanded, "Cell site location information is no different than what a pen register collects under the Constitution."
3. They can be overruled by the Supreme Court ("We hold we were wrong when we decided Smith v. Maryland.") This is the last choice for obvious practical reasons, and it involves more scrutiny.
