933 F.3d 110
2d Cir.2019Background
- FBI seized a copy of Playpen, a Tor hidden-service child‑pornography forum, and operated it from a government server in the Eastern District of Virginia.
- To identify site users despite Tor anonymization, the FBI deployed a Network Investigative Technique (NIT) that delivered code to visitors’ computers and returned identifying data (including IP address and OS username) to the government server.
- A magistrate in the Eastern District of Virginia issued the NIT warrant authorizing searches of “activating computers”; the NIT was executed nationwide and identified a user tied to Robert Eldred.
- Agents later obtained a Vermont warrant to search Eldred’s laptop, which produced child‑pornography evidence; Eldred moved to suppress on the ground that the NIT warrant exceeded the issuing magistrate’s territorial authority under Rule 41(b) and 28 U.S.C. §636(a).
- The district court denied suppression, concluding the Rule 41(b) violation was not a constitutional defect and that officers acted in good faith; Eldred pleaded guilty reserving the suppression appeal.
- The Second Circuit affirmed, holding that even if the NIT warrant were invalid for territorial reasons, the good‑faith exception to the exclusionary rule applied and suppression was not required.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Validity of NIT warrant under Rule 41(b) / §636(a) | NIT warrant exceeded issuing magistrate’s territorial jurisdiction and thus was void (no lawful authority to authorize searches outside district) | Warrant authorized searches of "activating computers" and affidavit described operations; magistrate had authority at least within district and good‑faith reliance was reasonable | Court did not decide definitively whether warrant violated Rule 41(b) / §636(a), but noted ambiguity and that 2016 Rule 41 amendments now address similar warrants |
| Fourth Amendment / exclusionary rule applicability | If warrant was issued without jurisdiction, evidence should be suppressed as the warrant is void ab initio and thus invalid under the Fourth Amendment | Even if constitutionally defective, officers reasonably relied on a facially sufficient warrant and supporting affidavit; exclusionary rule’s deterrence rationale does not justify suppression | Suppression denied under the Leon good‑faith exception: officers acted in objectively reasonable reliance, so evidence admissible |
| Whether the good‑faith exception applies to warrants void ab initio | Good‑faith exception should not apply when a warrant is void for lack of issuing judge’s authority | Good‑faith exception can apply so long as executing officers reasonably believed the warrant was valid; magistrate’s error does not implicate officer misconduct | Good‑faith exception applies even if warrant were void ab initio; exclusion would not serve deterrence against police misconduct |
| Whether government’s internal conduct (seeking rule change, multiple reviews) shows deliberate disregard | DOJ’s push to amend Rule 41 and internal review show government knew warrants like this were unauthorized | Consulting counsel and briefing the magistrate demonstrate care, not recklessness; novel tech issues justify counsel input | Government’s conduct did not demonstrate deliberate or reckless disregard; seeking rule clarification does not show lack of good faith |
