961 F.3d 1095
10th Cir.2020Background
- In 2015 the FBI seized the PlayPen server (hosted in the Eastern District of Virginia) and used government malware, deployed under a Virginia magistrate’s warrant, to identify site visitors on the Tor network.
- The malware produced IP addresses; one IP traced to an Oklahoma address, and an Oklahoma magistrate issued a second warrant to search that residence. The search uncovered extensive child‑pornography files on Arterbury’s computer.
- The Northern District of Oklahoma suppressed the evidence, holding the Virginia warrant void under pre‑2016 Rule 41 and rejecting the Leon good‑faith exception; the government filed an interlocutory appeal but withdrew it and dismissed the indictment without prejudice.
- The Tenth Circuit later, in United States v. Workman, reversed suppression in a separate PlayPen prosecution, applying Leon to similar facts and concluding circuit precedent and Supreme Court authority required denying suppression.
- The government then re‑indicted Arterbury; he moved to enforce the earlier suppression order under collateral estoppel (issue preclusion). The district court denied the motion after applying a due‑process‑oriented test and finding reprosecution not fundamentally unfair.
- The Tenth Circuit reversed: it held federal common‑law collateral estoppel precluded relitigation of the suppression ruling (despite the prior dismissal without prejudice) and rejected the government’s change‑in‑law argument based on Workman.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Arterbury can invoke collateral estoppel to bar relitigation of the suppression ruling after dismissal without prejudice | Arterbury: prior court actually and necessarily decided suppression; parties had a full and fair chance to litigate; dismissal without prejudice should be treated as final for issue‑preclusion | Government: no final judgment; Workman changed the law so relitigation is permitted | Held: Federal common‑law collateral estoppel applies; prior suppression ruling precludes relitigation despite dismissal without prejudice; vacate denial of motion to enforce suppression |
| Whether collateral estoppel in this federal criminal case must be limited or augmented by a due‑process test | Arterbury: need only satisfy common‑law elements of issue preclusion; no additional due‑process showing required | Government: district court may apply a due‑process‑oriented federal rule to allow reprosecution | Held: Court erred to impose due‑process conditions; federal common‑law collateral estoppel governs and was satisfied |
| Whether an intervening change in law (Workman) allows the government to relitigate | Arterbury: Workman did not change the governing legal principles; it applied existing Supreme Court precedent | Government: Workman created controlling circuit law that altered the legal landscape and permits relitigation | Held: Workman did not change controlling law; it applied existing Supreme Court precedent (Leon and related cases); no change‑in‑law exception applies |
| Whether Leon’s good‑faith exception can apply when an issuing magistrate exceeded geographic authority | (implicit in estoppel claim) Arterbury: district court already decided Leon did not apply; that issue was actually litigated and precluded | Government: Workman held Leon applied to these facts, undermining the prior ruling | Held: Whether Leon applies was previously decided for Arterbury and is precluded by collateral estoppel; court must enforce earlier suppression order (i.e., bar relitigation) |
