110 F.4th 999
7th Cir.2024Background
- The FBI took control of the Playpen dark-web child pornography website in 2015 and used a Network Investigative Technique (NIT) to identify users.
- Donald Dorosheff was identified as a Playpen user through the NIT, leading to the search of his residence in Illinois, where child pornography was found.
- Dorosheff was charged with receipt and possession of child pornography and moved to suppress evidence, arguing the NIT warrant was invalid under Rule 41 of the Federal Rules of Criminal Procedure because it was issued by an out-of-district magistrate judge.
- The district court agreed the magistrate’s authority was exceeded under Rule 41 but denied suppression, applying the good-faith exception to the exclusionary rule.
- On appeal, Dorosheff argued that the DOJ’s efforts to amend Rule 41 showed they knew such warrants were invalid, thus defeating the good-faith exception.
- The Seventh Circuit joined other circuits in affirming the application of the good-faith exception to evidence obtained via the Playpen NIT warrant.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the NIT warrant was invalid due to Rule 41 limits | Warrant was valid or good faith exception applies | Warrant invalid since magistrate had no authority outside her district | Rule 41 not satisfied, but good faith exception applies |
| Applicability of good-faith exception to NIT warrant | Officers acted reasonably, relying on judge's authority | DOJ knew warrants were invalid, so good faith exception should not apply | Good-faith exception applies |
| Relevance of DOJ's efforts to amend Rule 41 | Amendment effort does not show warrant was necessarily invalid | DOJ's advocacy is evidence of knowledge of invalidity; should defeat good faith | DOJ’s advocacy does not undermine good faith |
| Use of general vs. tracking device warrant forms | Form used is irrelevant to good-faith analysis | Agent’s use of general form showed knowledge of lack of authority | Form choice irrelevant; focus is on objective good faith |
