United States v. Ganias
824 F.3d 199
| 2d Cir. | 2016Background
- In Nov. 2003 Army CID agents executed a warrant at accountant Stavros Ganias’s office, created forensic "mirror" images of three hard drives, and took them off-site; the mirrors contained both files responsive to the warrant (for two client companies) and non-responsive personal/third‑party data.
- Copies of the mirrors were retained (one in evidence storage; working copies sent to forensic examiners); forensic review by Army and IRS examiners began in mid‑2004 and produced a set of responsive files on separate media by late 2004.
- The Government did not return or destroy non‑responsive material after that review; the investigation later expanded to include Ganias, and in April 2006 the Government obtained a new warrant to search the preserved mirrors for evidence of Ganias’s tax crimes.
- Ganias moved to suppress the evidence obtained from the 2006 search, arguing the long retention of non‑responsive files violated the Fourth Amendment and tainted the later warrant; the district court denied suppression.
- A panel initially ruled for Ganias and ordered suppression; the en banc Second Circuit affirmed the conviction on the alternative ground that the Government acted in objectively reasonable good faith reliance on the 2006 warrant, so suppression was not required.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether retention of full forensic mirrors (containing non‑responsive data) beyond the time needed to extract responsive files violated the Fourth Amendment | Ganias: once responsive files were segregated (by ~Dec.2004), retention of non‑responsive mirrors for years was an unlawful seizure/over‑seizure; later search in 2006 was tainted and evidence must be suppressed | Gov’t: warrant expressly authorized seizure/mirroring of drives for off‑site forensic review; retention may be necessary for authentication, preservation, and third‑party investigations; no clear precedent made retention unlawful | Court: did not decide whether retention violated the Fourth Amendment — declined to reach merits because other ground disposed of case |
| Whether evidence from the 2006 search must be suppressed under Leon/good‑faith despite any earlier Fourth Amendment problem | Ganias: later warrant cannot "cleanse" prior unconstitutional retention; magistrate lacked full disclosure that responsive files had been segregated and non‑responsive files retained long after | Gov’t: agents disclosed to magistrate that mirrors had been seized in 2003, contained non‑responsive data, and had been analyzed; officers reasonably relied on a neutral magistrate’s issuance of the 2006 warrant (objectively reasonable under Leon) | Court: Government demonstrated objectively reasonable good‑faith reliance on the 2006 warrant; suppression not warranted; conviction affirmed |

- Davis v. United States, 564 U.S. 229 (2011) (exclusionary rule is a last resort; good‑faith reliance on binding precedent may preclude suppression)
