In Re the United States for Orders Pursuant to Title 18
MEMORANDUM AND ORDER ON GOVERNMENT’S MOTION FOR REQUEST FOR REVIEW
INTRODUCTION
As part of an ongoing criminal investigation, the government sought a court order requiring certain cellular telephone companies to disclose a customer’s cellular telephone records. In doing so, the government relied on provisions of the Stored Communications Act (SCA),
BACKGROUND
Cellular telephone networks consist of a grouping of interconnected “cells.” Each cell is serviced by a tower whose antennae transmit and receive signals from cellular telephones within a specific area of coverage. As a caller moves (or roams) through these areas, his or her phone is automatically switched to the tower that (at least in theory) provides the best reception. Cellular telephone companies maintain records of this switching information. The information is used, for among other business purposes, to assess roaming charges. However, the close proximity of cell towers in urban (and some suburban) areas has also imbued cell site information with a value to law enforcement: cell site information coupled with a basic knowledge of trigonometry makes it possible to identify with reasonable certainty the location from which a call was made. 3
The prospect that cell site information might be used as a surveillance tool has led to a disagreement among courts over the standard to be applied when the government requests access to prospective or “real time” cell site information, although a strong majority has opted for the probable cause standard.

DISCUSSION
Stored Communications Act
The issue presented by this case is whether historical cell site information is obtainable under
Second, the court must determine whether historical cell site information is “a record or other information pertaining
Finally, the court must determine whether historical cell site information is “content” information, which is defined by the SCA as “any information concerning the substance, purport, or meaning of [a] communication.”
Fourth Amendment
The issue remains, however, whether the Fourth Amendment’s probable cause requirement nonetheless preempts the more relaxed provisions of the SCA governing the disclosure of historical cell cite information. What concerned the Magistrate Judge was a scenario in which the government utilized access to forward-looking or real time cell site information to physically track a cell phone user. In this circumstance, the Magistrate Judge could see “no reason to treat cell phone tracking any different than other forms of tracking which routinely require probable cause.”
In re Applications,
A second consideration (the issue that concerned the Magistrate Judge, although not raised by the facts of this case) is this: even if an order requiring the disclosure of prospective cell site information allowed the government to “track” a suspect (or more accurately his or her phone) into a protected area like a home, would any reasonable Fourth Amendment expectation of privacy be compromised as a result? Unlike
United States v. Karo,
Finally, any speculation about improper government “tracking” is premature. Fourth Amendment questions are difficult to resolve in the abstract. Assuming — as the Magistrate Judge warned — that prospective or real time cell site information is capable of transforming a cellular telephone into a “tracking device,” 11 it should be left to an aggrieved defendant to litigate the constitutionality of warrantless law enforcement surveillance by means of such a “device” in the more appropriate context of a motion to suppress.
ORDER
For the foregoing reasons, the decision of the Magistrate Judge is
REVERSED.
SO ORDERED.

. The "specific and articulable facts” standard requires a showing of a particularized and objective basis for a suspicion of criminal activity.

that disclosure of historical data is proper under the SCA’s specific and articulable facts standard.

In re Applications, 2007
WL 2296406, at *4. Magistrate Judge Alexander reasoned that because "historical records provide relatively sterile data ... while historical cell site information provides the location of a person or object," historical cell site information is tantamount to information provided by a "tracking device.”

. As observed earlier, in this scenario most courts have required a showing of probable cause as a predicate to disclosure.
