California continued its long-standing tradition for forward-thinking privacy laws today when Governor Jerry Brown signed a sweeping law protecting digital privacy rights.
The landmark Electronic Communications Privacy Act bars any state law enforcement agency or other investigative entity from compelling a business to turn over any metadata or digital communications—including emails, texts, documents stored in the cloud—without a warrant. It also requires a warrant to track the location of electronic devices like mobile phones, or to search them.
Unfortunately, state laws can only limit the actions of the state’s citizens and state agencies; it has no impact on federal agencies.
