Gonzales v. Duenas-Alvarez
The Court ruled that a lawful permanent resident convicted under a California car-theft law that also covers aiding and abetting can still be deported as having committed a generic "theft offense," rejecting the Ninth Circuit's view that aiding-and-abetting liability falls outside that category.
The decision restores a uniform national approach to how immigration judges classify state theft-related convictions, making it harder for immigrants convicted as accomplices to avoid removal by arguing their role was too indirect to count as generic theft.
“It requires a realistic probability, not a theoretical possibility, that the State would apply its statute to conduct that falls outside the generic definition of a crime.”
The standard the Court set for showing a state law sweeps more broadly than a generic federal crime category.
How it got here: An immigration judge and the Board of Immigration Appeals found Duenas-Alvarez removable; the Ninth Circuit remanded based on its own precedent, and the government sought Supreme Court review.
The Case in Depth
What happened
Luis Duenas-Alvarez, a lawful permanent resident, was convicted under a California law criminalizing driving or taking someone else's car without permission, which also punishes anyone who acts as "a party or an accessory to or an accomplice in" such conduct. The federal government sought to deport him, arguing his conviction counted as a "theft offense" under immigration law, which mandates removal for aliens convicted of theft offenses carrying at least a one-year sentence.
The question before the Court
Does the federal immigration law term "theft offense," which triggers deportation, also cover someone convicted of aiding and abetting a theft rather than committing it directly?
Why it matters
Immigrants convicted of aiding or facilitating a theft — not just those who personally took the property — can now be deported the same way as principal offenders. This narrows a legal argument that had let some immigrants in the Ninth Circuit avoid removal, and it clarifies for immigration judges nationwide how to classify state theft convictions under federal deportation law.
What changes now
The Court vacated the Ninth Circuit's judgment and sent the case back for further proceedings consistent with this opinion. The Ninth Circuit and immigration agencies must now apply the ruling that aiding-and-abetting convictions can count as generic theft offenses, and the lower court may still need to address Duenas-Alvarez's separate, unresolved arguments about accessories after the fact and joyriding, which the Court did not decide.
What this does not decide
The Court did not decide whether the California statute's coverage of "accessories after the fact" or of joyriding takes it outside the generic definition of theft, since those arguments were outside the question the Court agreed to review and had not been addressed by the lower court.
Concurrences and dissents
Concurrence in part — Justice Stevens
Justice Stevens joined the majority's discussion of the legal framework and the judgment but declined to join the part of the opinion analyzing whether California's specific application of the natural-and-probable-consequences doctrine was unusually broad. He argued the Court should generally avoid resolving disputed questions of state law before a court of appeals has addressed them, since circuit judges know their own states' law better.
How the Court got there
The legal reasoning, step by step
- The Court applied the framework from Taylor v. United States, under which a listed federal offense category like "theft offense" is defined by its generic meaning across state criminal codes, not by the precise wording of the particular state statute involved.
- The Court accepted the generic definition of theft used by the Board of Immigration Appeals and most circuits: taking or exercising control over someone's property without consent, intending to deprive the owner of its benefits, even if only temporarily.
- Because American law has long since erased the old distinction between someone who personally commits a crime and someone who aids or abets it before or during the crime, the Court reasoned that generic "theft" already includes aiders and abettors, not just principal offenders.
- The Court then asked whether California's specific version of aiding-and-abetting liability — which holds an accomplice responsible for any crime that naturally and probably results from the crime he intended — was unusually broad compared to other states, since an unusually broad rule might sweep in conduct beyond generic theft.
- The Court held that to prove a state statute reaches beyond the generic definition, a defendant must show a realistic probability that courts actually apply the law that broadly, pointing to specific cases — not just a theoretical possibility drawn from the statute's language.
- Because Duenas-Alvarez could not point to actual California cases applying the natural-and-probable-consequences doctrine more broadly than other states apply similar rules, the Court concluded California's theft-related law fits within the generic theft category.
