Rule of Law:
A district court's "de novo determination" of a magistrate's report on a dispositive pretrial motion, such as a motion to suppress, does not require a new evidentiary hearing, even when witness credibility is central. This procedure, where the ultimate adjudicatory power rests with the Article III district judge, does not violate the Due Process Clause of the Fifth Amendment or Article III of the Constitution.
Facts:
- On August 8, 1976, police officers arrested respondent Raddatz for illegal use of a weapon after finding him next to a man bleeding from the head.
- Raddatz made an incriminating statement to the arresting officers, claiming he brought a gun to a family dispute.
- Months later, agents from the Bureau of Alcohol, Tobacco, and Firearms interviewed Raddatz at his home about the gun.
- During this and a subsequent interview, Raddatz made further incriminating statements, changing his story about how he obtained the gun.
- Raddatz later claimed his statements were involuntary, alleging that the federal agents had promised him that the charges would be dismissed if he cooperated.
- The federal agents testified that they never promised to have the charges dismissed, only that they would inform the U.S. Attorney of his cooperation.
Procedural Posture:
- Raddatz was indicted in the U.S. District Court for the Northern District of Illinois.
- Raddatz filed a pretrial motion to suppress incriminating statements.
- The District Court, acting as the trial court, referred the motion to a U.S. Magistrate for an evidentiary hearing.
- The Magistrate conducted the hearing and issued a report recommending that the motion to suppress be denied, based on a finding that the federal agents were more credible than Raddatz.
- Raddatz filed objections to the Magistrate's report with the District Court.
- The District Court reviewed the hearing transcript and the Magistrate’s report but declined to hold a new evidentiary hearing, accepted the Magistrate's recommendation, and denied the motion to suppress.
- Raddatz was subsequently found guilty at a stipulated bench trial and sentenced.
- Raddatz (appellant) appealed to the U.S. Court of Appeals for the Seventh Circuit.
- The Court of Appeals, an intermediate appellate court, reversed the conviction, holding that due process required the District Court to personally hear the testimony when witness credibility was dispositive.
- The United States (petitioner) sought and was granted a writ of certiorari by the U.S. Supreme Court.

Issue:
Does the Federal Magistrates Act, by permitting a district court to decide a suppression motion based on a magistrate's record and recommendation without conducting its own evidentiary hearing, violate a defendant's rights under the Due Process Clause of the Fifth Amendment or Article III when witness credibility is the central issue?
Opinions:
Majority - Chief Justice Burger
No, the Federal Magistrates Act does not violate the Due Process Clause or Article III. The statutory phrase 'de novo determination' does not mean 'de novo hearing,' and legislative history confirms Congress intended to give district judges discretion to decide whether to rehear testimony. Under the Mathews v. Eldridge balancing test, due process is satisfied because the interests at stake in a suppression hearing are of a lesser magnitude than those at trial, and the statutory scheme provides sufficient safeguards against an erroneous determination while serving the significant public interest in judicial efficiency. The procedure does not violate Article III because the ultimate decision-making authority remains with the district court judge, who has plenary control over the magistrate and the proceedings, rendering the magistrate an adjunct of the court.
Concurring - Justice Blackmun
No. When a district court adopts a magistrate's credibility-based determination that is unfavorable to the defendant, the procedure does not violate due process. In this context, the magistrate system serves as a 'backup' jurist, providing a second level of procedural protection that enhances reliability. The system does not violate Article III because the district judge retains complete supervisory control over the magistrate's activities, ensuring there is no threat to the independence of judicial decisionmaking.
Concurring-in-part-and-dissenting-in-part - Justice Powell
No, on the statutory interpretation, but Yes, on the constitutional question. While the statute grants district courts discretion, the Due Process Clause requires a district court to rehear crucial witnesses when a suppression hearing turns solely on witness credibility. The risk of erroneous deprivation is too high when the factfinder has not personally heard and observed the witnesses whose testimony is determinative. Therefore, the district court's failure to conduct its own hearing in this case violated due process.
Dissenting - Justice Stewart
Yes, this procedure violated the statute itself. The statutory requirement of a 'de novo determination' means an independent judgment that accords no deference to the prior resolution. When a case involves a direct conflict in testimony where credibility is the sole issue, a judge cannot make a truly independent, 'de novo' determination based on a cold transcript without personally observing the demeanor of the witnesses. By not holding a hearing, the District Judge necessarily gave impermissible 'special weight' to the Magistrate’s credibility assessment.
Dissenting - Justice Marshall
Yes, the procedure is impermissible under both the Due Process Clause and Article III. Due process embodies the principle that 'The one who decides must hear,' which requires a factfinder to hear live testimony whenever credibility is dispositive and cannot be fairly resolved on a cold record. Furthermore, allowing a non-Article III magistrate to effectively make the final determination of case-dispositive facts in a criminal proceeding is an unconstitutional delegation of the 'judicial Power.' Article III guarantees a criminal defendant an independent determination of such facts by a judge with life tenure and salary protection.
Analysis:
This decision significantly bolstered the authority and utility of federal magistrate judges, confirming their role in handling dispositive pretrial matters to alleviate district court caseloads. By defining 'de novo determination' as a review of the record rather than a mandatory new hearing, the Court granted district judges substantial discretion and promoted judicial efficiency. The ruling also established that the procedural protections required for pretrial suppression hearings are less stringent than those for a full criminal trial, setting a precedent that affects how due process challenges to such hearings are evaluated. Future litigation would explore the limits of this discretion, particularly in cases where a judge might reject a magistrate's credibility findings without hearing the witnesses.
