USA v. Munoz, No. 22-11574 (11th Cir. 2024)
Annotate this Case
Three years after becoming a U.S. citizen, Melchor Munoz pleaded guilty to a drug-conspiracy offense, admitting under oath that he began trafficking marijuana in 2008. The government sought to denaturalize Munoz under 8 U.S.C. § 1451(a), alleging that his prior participation in the drug conspiracy made him ineligible for citizenship. The government moved for judgment on the pleadings, arguing that Munoz was collaterally and judicially estopped from denying his 2008 involvement. The district court granted the motion and entered a judgment denaturalizing Munoz.
Previously, the United States District Court for the Northern District of Florida accepted Munoz’s guilty plea, where he admitted to drug trafficking starting in 2008. Munoz later moved to vacate his conviction, arguing ineffective assistance of counsel, but the motion was denied. The government then proceeded with the denaturalization action, and the district court granted the government’s motion for judgment on the pleadings, applying both collateral and judicial estoppel.
The United States Court of Appeals for the Eleventh Circuit reviewed the case. It concluded that collateral estoppel was unavailable because the starting date of Munoz’s drug offense was unnecessary to his prior conviction. The court also found that the district court abused its discretion in applying judicial estoppel, as the findings lacked evidentiary support. The Eleventh Circuit vacated the district court’s order and remanded for further proceedings, allowing Munoz to litigate the issue of when he began participating in the drug conspiracy.
