State v. Brown

Summary

The court affirmed suppression of historical and prospective cell-site location information obtained under three ex parte orders and affirmed dismissal of the criminal charges. Historical data violated the Fourth Amendment because it was obtained without a probable-cause warrant, while prospective data was obtained in violation of the governing statute and was subject to suppression because it implicated important privacy interests. The court also held that the state failed to prove inevitable discovery of a witness's statement and potential testimony because it did not show that the witness would have cooperated absent the unlawfully obtained data.
