Lopez v. Gonzales: A State Felony Is Not Illicit Trafficking When Federal Law Treats It as a Misdemeanor

By Aneeta Mishra and Timothy Chan

Published April 29, 2026

Lopez ties the illicit-trafficking aggravated-felony category to conduct punishable as a felony under the federal Controlled Substances Act.

South Dakota labeled possession a felony

Jose Antonio Lopez was convicted of aiding and abetting cocaine possession, a state felony. Federal law treated the underlying simple possession conduct as a misdemeanor.

Illicit trafficking implies unlawful commerce

The INA incorporates a drug-trafficking crime defined by federal law. Ordinarily, trafficking involves commercial dealing, and the incorporated definition requires conduct punishable as a federal felony.

State labels do not control the federal category

A state cannot transform federally misdemeanor conduct into an INA aggravated felony simply by calling it a felony. Uniform federal classification avoids divergent immigration consequences based solely on state labeling.

Disposition

The Court reversed the aggravated-felony determination. The conviction could still have other immigration consequences, including removability as a controlled-substance offense.

Key takeaways

• Compare the state elements with the federal Controlled Substances Act.
• Separate state grading from federal felony status.
• Distinguish removability from aggravated-felony bars.
• Analyze the conviction record and any recidivist findings.
