Denise Donovan, a federal agent, obtained a search warrant from a local magistrate after submitting an affidavit with limited details on probable cause. Officers executed the warrant at Darius Dixon's residence and seized documents. Dixon moved to suppress the evidence when the warrant was later found to lack probable cause. The court denied the motion because the officers had relied on the magistrate's issuance in good faith.
Dolores Diaz, a state prosecutor, prepared and signed a search warrant for Diego Duarte based on her own investigation. Officers executed the warrant at Duarte's home and seized evidence. Duarte moved to suppress on the ground that the issuing official lacked neutrality. The court held the warrant invalid because the prosecutor was not a detached and neutral magistrate.

Doris Duffy, the state attorney general, personally investigated a suspected crime and then issued a search warrant for Delilah Duran's property. Officers executed the warrant and recovered evidence. Duran moved to suppress on the ground that the issuing official lacked neutrality. The court granted the motion because the attorney general's investigative role disqualified her as a detached and neutral magistrate.
Duffy Construction applied for an administrative search warrant from a municipal court clerk to inspect its worksite. The clerk reviewed the application and found probable cause before issuing the warrant. Officers conducted the inspection and cited the company for violations. Duffy Construction challenged the warrant on the ground that only a judge could issue it. The court upheld the warrant because the clerk was sufficiently independent from law enforcement.
Diego Duarte was arrested inside his home after officers entered without obtaining any warrant. The officers had probable cause but no neutral judicial review. Duarte moved to suppress statements made after the entry. The court suppressed the evidence because the absence of a warrant issued by a detached and neutral magistrate rendered the home entry unconstitutional.
Darius Dixon was arrested inside his apartment after officers used a remote system to unlock the door without obtaining an arrest warrant. The officers had probable cause but no neutral judicial review. Dixon moved to suppress evidence obtained after the entry. The court granted the motion because an arrest inside a residence requires a warrant issued by a detached and neutral magistrate absent exigent circumstances.
A judicial officer qualifies when institutionally insulated from law enforcement and free of any financial, professional, or personal interest in the warrant. A prosecutor actively involved in the investigation does not qualify. A court clerk may qualify if sufficiently independent and capable of determining probable cause.

The warrant is invalid and evidence obtained through its execution is subject to suppression. The exclusionary rule applies because the constitutional safeguard of neutral judicial review is absent. Officers cannot claim good-faith reliance on such a warrant.
Supporting sources
Yes. Officers may rely on a warrant issued by a detached and neutral magistrate even if the warrant later proves to lack probable cause. Suppression is required only when the officers' reliance was objectively unreasonable or the magistrate abandoned neutrality.
Supporting sources
Yes. An arrest warrant requires issuance and signature by a neutral judicial officer who has determined probable cause. A document bearing only a prosecutor's name is not a valid warrant and cannot authorize an arrest.

…the police can invade the home to enforce it, provided, of course, that they obtain a determination of probable cause from a neutral magistrate. One of the reasons for the Court's holding in Griswold v. Connecticut , 381 U. S. 479 (1965), was precisely the possibility, and repugnance, of permitting searches to obtain evidence…
