United States v. Trace Thoms
684 F.3d 893
9th Cir.2012Background
- This is an interlocutory appeal from a district court’s suppression ruling following a magistrate’s Franks hearing on a search warrant.
- A magistrate recommended denying suppression; the district court granted suppression without a new evidentiary hearing, relying on the live-record review.
- The government contends a de novo evidentiary hearing is required when reversing a magistrate’s credibility findings adverse to the government.
- The Thomses challenged the district court’s procedure and privilege to hold a de novo hearing, arguing due process requires live testimony.
- The court adopts a middle-ground rule: reversal of a magistrate’s credibility findings favorable to the government generally requires live-demeanor review, with narrow exceptions, and remands for reconsideration.
- The ultimate holding vacates and remands for a de novo hearing consistent with the new rule.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the government has an absolute right to a de novo hearing when a district court reverses a magistrate’s credibility finding. | Government opposes; Ridgway-like rule is symmetrical | Bergera/Raddatz framework allows limited de novo hearing | Not absolute; adopt narrowing rule |
| What standard governs when a district court may reverse a magistrate’s credibility finding without a new hearing. | Government seeks de novo hearing in most cases | Due process does not require in all cases | District court abuses discretion if reversal occurs without live demeanor review unless no legally sufficient evidentiary basis for credibility |
| What rule should govern live testimony versus cold-record review to protect integrity of fact-finding. | Live testimony preserves integrity; government interest in demeanor evidence | Cold-record review can suffice in some instances | Adopt a narrower rule favoring live testimony, with a limited de novo hearing on remand |
| Is the de novo hearing required to be a full rerun of the magistrate hearing? | Full rerun may be necessary to preserve integrity | Efficiency may permit a more limited hearing | Hearing need not be a complete rerun; district court may tailor the hearing on remand |
| How should the rule apply to cases where the magistrate’s credibility findings had no legally sufficient evidentiary basis? | If lack of basis, no de novo hearing needed | In such cases, judgment as a matter of law may apply | Exception allows no de novo hearing when findings lack evidentiary basis |
