(The Hill) The privacy of emails, photos stored in the cloud, even heart rate history from a smartwatch could be at stake, according to civil libertarians, as the Supreme Court takes up a potential blockbuster case after Thanksgiving.
When they return to the bench after the holiday, the justices will weigh whether the history of cell phone locations stored by a phone service provider is searchable without a warrant.
The case, Carpenter v. U.S., centers on Timothy Carpenter, who argues the government violated his Fourth Amendment protection against unreasonable search and seizure when it obtained his cell phone location records from MetroPCS and Sprint without a warrant. Authorities then used that data as trial evidence to convict him of a string of robberies at Radio Shack and T-Mobile stores in Michigan and Ohio from December 2010 to March 2011.
The government argues that it was well within its rights under the Stored Communications Act (SCA) of 1986 to get a court order for the records. The law allows this type of data to be searched if the government can show reasonable grounds to believe it will be relevant to a criminal investigation.
To obtain a warrant, law enforcement officers, however, must show there is probable cause.
But beyond the law, the government is arguing that Carpenter lacks a legitimate expectation of privacy because he voluntarily turned his location information over to a third party when he signed up for cell service. It’s a legal theory known as the third-party doctrine.
“Petitioner lacks any subjective expectation of privacy in phone-company records of historical cell-site data because they are business records that MetroPCS and Sprint create for their own purposes,” Acting Solicitor General Noel Francisco, Acting Assistant Attorney General Kenneth Blanco and DOJ Attorney Jenny Ellickson argued in a court brief.
American Civil Liberties Union (ACLU) staff attorney Nathan Freed Wessler, who’s representing Carpenter, called the implications of that argument “stunning.”
“If the government’s position wins, it would imperil the search queries people enter into Google or WebMD, our complete browsing histories showing everything we read online, the heart rate data from a smartwatch saved by Apple, a person’s whole life in photos uploaded to the cloud and so much more,” he said.
“In the 21st century we really can’t go about our daily lives without creating these pervasive, highly sensitive digital records held by companies we interact with.”
The ACLU also argues the government is relying on an outdated law.
Though it was updated in part in 1994, Wessler said the SCA really hasn’t been touched since 1986. At that time there were only 1,000 cell sites in the U.S. and less than half of one percent of Americans had a cell phone. Today, he said more than 300,000 cell sites exist and 95 percent of Americans have cell phones.
But the government argues that cell phone location information isn’t personal.
