A June 2018 decision rendered by the Supreme Court of the United States established an interesting principle on digital privacy in a case related to a criminal proceeding.

The decision stated that the government must obtain a warrant in order to collect historical cell site location information (CSLI) of customers held by the cellphone companies. The case’s decision is based on whether police must require a warrant in order to access information from users generated by cellphones of a suspect in a criminal investigation. This decision implies that in the future, law enforcement authorities will not have an “unrestricted access to a wireless carrier’s database of physical location information” (From the majority by Justice John Roberts).
