Courts have been similarly divided on whether car passengers, or nonowners, have legal authority to challenge GPS evidence against them.
The Jones decision has also been invoked in court disputes over the NSA's telephone records collection. A federal judge in Washington cited the opinions of Alito and Sotomayor in the Jones case to find that telephone users have a reasonable expectation of privacy and to declare the NSA program likely unconstitutional. A federal judge in New York rejected a plea from civil libertarians to invoke those same opinions and instead upheld the NSA program.
Police and judges also are wrestling with the privacy implications of other modern forms of surveillance. In Washington state, for example, privacy advocates are arguing that the Jones case requires a court to throw out warrantless video surveillance captured by a pole camera left by police for a month outside a defendant's house in a drugs and weapons case.
