In a 6-3 decision, the Supreme Court has ruled that law enforcement agencies must obtain a warrant before accessing cloud-stored personal data, even when that data is held by third-party service providers. The decision significantly strengthens Fourth Amendment protections in the digital age.
Justice Sotomayor, writing for the majority, stated that the third-party doctrine cannot be applied broadly to the vast quantities of personal information stored in modern cloud services. The ruling overturns several lower court decisions that had permitted warrantless access.
