918 F.3d 509
6th Cir.2019Background
- Sirous Asgari, an Iranian national and scientist, visited the U.S. in 2011–2012 and later worked at Case Western Reserve University’s Swagelok Center on corrosion-related research; investigators suspected he misstated visa information and transmitted technology to Iran.
- FBI Special Agent Timothy Boggs prepared a 10-page affidavit and obtained a 2013 warrant to search Asgari’s personal email for evidence of visa fraud (18 U.S.C. § 1001) and sanctions violations; a 2015 warrant followed based on evidence from the 2013 search.
- A grand jury indicted Asgari on trade-secret, wire-fraud, and visa-fraud counts; Asgari moved to suppress evidence obtained from the warrants.
- The district court held the 2013 affidavit lacked probable cause and that the Leon good-faith exception did not apply (finding alleged intentional/misleading statements), suppressing evidence from both warrants.
- The government appealed, arguing that even if probable cause were debatable, the Leon good-faith exception applies and the alleged affidavit errors were not deliberate or reckless.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Probable cause for 2013 warrant | Affidavit failed to establish probable cause to search emails for visa fraud or sanctions violations | Affidavit contained significant facts (travel, emails with Case Western, ties to Sharif Univ., Swagelok Center’s defense links) supporting probable cause | Court did not decide probable cause conclusively but found good-faith reliance sufficient |
| Applicability of Leon good-faith exception | Leon’s exception should not apply because affidavit was “so lacking in indicia of probable cause” | Investigators reasonably relied on a neutral magistrate’s warrant; affidavit was not barebones | Leon applies; affidavit provided more than barebones support for a reasonable officer to rely on the warrant |
| Alleged false/misleading statements in affidavit (Franks challenge) | Affidavit contained intentional or reckless falsehoods and omissions (paragraph 9 errors) that misled magistrate | Errors were minor, inferential, or supported by notes; not deliberate or reckless; some criticisms rest on inferences | No sufficient evidence of deliberate or reckless falsehoods or reckless omissions; Franks standard not met |
| Suppression of derivative evidence from 2015 warrant | Evidence from 2015 warrant was tainted by the defective 2013 warrant and should be suppressed | If Leon protects 2013 search, derivative evidence is admissible | Because Leon applies to 2013 warrant, suppression of derivative 2015 evidence was improper; case reversed and remanded |
