Federal Judge: Only Powered-Off Cell Phones Deserve Privacy Protections

A federal magistrate judge in New York recently ruled that cell phone location data deserves no protection under the Fourth Amendment and that accordingly, the government can engage in real-time location surveillance without a search warrant. In an opinion straight from the Twilight Zone, magistrate judge Gary Brown ruled two weeks ago that “cell phone users who fail to turn off their cell phones do not exhibit an expectation of privacy.”

The case in question involved a physician who the DEA believed had issued thousands of prescriptions for pain killers in exchange for cash. In March of this year, the DEA had obtained a warrant for his arrest, and, not knowing where he was, sought an order from magistrate judge Brown forcing the phone company to provide real-time data identifying the location of the physician’s phone.

Although the DEA agents requested a search warrant and the judge found that there was probable cause to believe that the cell phone location data would assist in the location and apprehension of an individual for whom there was already a valid arrest warrant, the judge later published a 30-page opinion further stating that he didn’t think the government needed to seek a search warrant in the first place.

Don’t Want the Government Tracking You? Turn Your Phone Off

In his puzzling opinion, the judge squarely criticizes people naive enough to expect privacy while also leaving their cell phones on when they’re not using them.

Given the ubiquity and celebrity of geolocation technologies, an individual has no legitimate expectation of privacy in the prospective location of a cellular telephone where that individual has failed to protect his privacy by taking the simple expedient of powering it off.

As to control by the user, all of the known tracking technologies may be defeated by merely turning off the phone. Indeed—excluding apathy or inattention—the only reason that users leave cell phones turned on is so that the device can be located to receive calls. Conversely, individuals who do not want to be disturbed by unwanted telephone calls at a particular time or place simply turn their phones off, knowing that they cannot be located.
