The Supreme Court on Monday agreed to consider whether law-enforcement officials need search warrants to obtain data about the location of cellphone users, a major case that raises questions about privacy rights in the digital age.
The high court said it would hear an appeal by a defendant who was convicted in part based on evidence prosecutors obtained from wireless service providers about the whereabouts of his cellphone at particular times.

The government didn’t obtain a search warrant for the cell data. Instead, it sought and obtained the data under the Stored Communications Act, which sets a lower standard that allows law enforcers to seek records when there are reasonable grounds for believing the information is relevant to a criminal investigation.
[The Defendant] sought to suppress the evidence, arguing it was obtained in violation of his Fourth Amendment right to be free from unreasonable government searches.
An appeals court ruled for the government, citing a 1979 Supreme Court ruling involving home telephone records that said people don’t enjoy Fourth Amendment protection for information they voluntarily reveal to a third party, such as a phone company.
