Florida court: Come back with a warrant to track suspects via mobile phone | Ars Technica. The Florida Supreme Court has ruled that persons have a right to privacy in location on their mobile phones. Unless a person voluntarily gives up such information, or unless a valid search warrrant is obtained from a court of competent jurisdiction, based upon a sworn affidavit, the Court has ruled that the rules in the digital age aren't different from the rules that have always obtained under the constitutional right to privacy. This limitation prohibits a long slide to a 1984 style of investigative action that will curb and limit the freedom of the citizen to move freely in a free society. I am happy that it is my state's highest court that has buttressed this most basic constitutional freedom.
