A judicial officer who is independent from law enforcement and the prosecution. The officer must determine probable cause before issuing a warrant. This requirement ensures an impartial review separate from the executive branch.
Neville Norton, a financial crimes agent, obtained a search warrant from a magistrate for client files at Nexus Financial. Agents executed the warrant and seized ledgers showing insider trading. A later ruling found the supporting affidavit lacked probable cause, yet the evidence remained admissible because the agents had relied on the magistrate's issuance.
Nicole Navarro, an exhibitor, faced seizure of a single film copy alleged to be obscene. Officers obtained a warrant from a neutral magistrate and seized the material for evidence. The exhibitor received permission to copy the work so exhibition could continue while awaiting a prompt judicial determination of obscenity.

A prosecutor belongs to the executive branch and cannot supply the required neutral review. Only a judicial officer independent of law enforcement can determine probable cause and authorize the warrant. An unsigned draft prepared by a prosecutor is not a valid warrant.
Supporting sources
The exception applies when officers reasonably relied on a warrant issued by a neutral magistrate. Suppression is not required unless the warrant was facially deficient, the magistrate abandoned neutrality, or officers misled the magistrate. The later finding of insufficient probable cause alone does not trigger exclusion.
Supporting sources
A prompt judicial determination of obscenity must occur. If no other copies exist, the exhibitor must be allowed to copy the seized work to continue exhibition pending final adjudication.
