Rule of Law:
The Fourth Amendment's exclusionary rule does not require suppression of evidence seized by police officers who acted in objectively reasonable reliance on a search warrant issued by a neutral magistrate, even if the warrant is subsequently found to be invalid due to the magistrate's clerical error.
Facts:
- The body of Sandra Boulware was discovered, leading police to investigate her boyfriend, Osborne Sheppard.
- The investigation uncovered that Sheppard had borrowed a car around the time of the murder, and a search of the vehicle revealed bloodstains, hair, and wire matching evidence found near the body.
- Based on this evidence, Detective Peter O’Malley drafted a detailed affidavit listing specific murder-related items to be seized from Sheppard's home.
- Because it was a Sunday, O'Malley could only find a pre-printed warrant form for searching for controlled substances, which he attempted to modify for the murder investigation.
- O'Malley presented the affidavit and the altered warrant form to a judge at his residence, pointing out that the form needed to be changed to authorize the search for the items listed in the affidavit.
- The judge told O'Malley he would make the necessary changes to authorize the search as requested, then signed the warrant and returned it.
- The judge failed to alter the substantive portion of the warrant, which still authorized a search for controlled substances and did not incorporate the affidavit's specific list of items by reference.
- Relying on the judge's assurances, officers executed the warrant, limiting their search to the items specified in the affidavit and discovering several incriminating pieces of evidence.
Procedural Posture:
- Osborne Sheppard was charged with first-degree murder in a Massachusetts trial court.
- At a pretrial suppression hearing, Sheppard's defense moved to suppress the evidence found at his residence, arguing the warrant was invalid.
- The trial judge found the warrant was constitutionally defective but denied the motion to suppress, ruling the police had acted in good faith.
- Following a trial, Sheppard was convicted of murder.
- Sheppard appealed to the Supreme Judicial Court of Massachusetts, the state's highest court.
- The Supreme Judicial Court reversed the conviction, holding that the evidence should have been suppressed because there was no 'good faith' exception to the exclusionary rule.
- The U.S. Supreme Court granted certiorari.

Issue:
Does the Fourth Amendment's exclusionary rule require the suppression of evidence obtained by police officers acting in objectively reasonable reliance on a search warrant that was technically defective due to the issuing judge's failure to make necessary clerical corrections?
Opinions:
Majority - Justice White
No. The exclusionary rule should not be applied when police officers act in objectively reasonable reliance on a warrant that is subsequently invalidated due to a judicial error. The purpose of the exclusionary rule is to deter police misconduct, not to punish the errors of magistrates and judges. In this case, the police officers took every reasonable step: they prepared a detailed affidavit establishing probable cause, presented it to a neutral judge, alerted the judge to the warrant form's defects, and were assured by the judge that he would make the necessary corrections. A reasonable officer would have concluded that the warrant authorized the search described in the affidavit, and it is unreasonable to require an officer to disbelieve a judge's explicit assurances that a warrant is valid. The critical mistake was the judge's, not the police's, and suppressing the evidence would serve no deterrent function.
Analysis:
This case, a companion to United States v. Leon, solidifies the 'good faith' exception to the exclusionary rule. It specifically extends the exception to situations involving a facially defective warrant where the defect results from a judge's clerical error. The decision emphasizes that the focus of the exclusionary rule is on police deterrence, thereby insulating police conduct from judicial errors when the officers' reliance on the judiciary is objectively reasonable. This precedent significantly limits the scope of the exclusionary rule, preventing the suppression of evidence due to mistakes made by the judicial branch rather than by law enforcement.
