Mellouli v. Lynch
The Court ruled that a lawful permanent resident's Kansas conviction for concealing pills in his sock did not make him deportable, because the federal removal law only reaches state drug crimes tied to a substance on the federal government's own controlled-substance list.
Since Kansas's paraphernalia law covered some drugs the federal government doesn't regulate, and prosecutors never had to prove which drug was involved, the conviction didn't count — reversing years of harsher treatment of minor paraphernalia charges compared to actual drug-possession convictions.
“The incongruous upshot is that an alien is not removable for possessing a substance controlled only under Kansas law, but he is removable for using a sock to contain that substance.”
The majority's core objection to treating paraphernalia convictions more harshly than drug possession convictions.
How it got here: An immigration judge ordered Mellouli deported; the Board of Immigration Appeals affirmed; the Eighth Circuit denied review; he asked the Supreme Court to step in.
The Case in Depth
What happened
Moones Mellouli, a Tunisian citizen and lawful permanent resident with two advanced degrees who worked as an actuary, was arrested during a DUI stop when officers found four unidentified pills — later acknowledged as unprescribed Adderall — hidden in his sock. He pleaded guilty only to a Kansas misdemeanor for possessing drug paraphernalia used to conceal a controlled substance, without ever admitting which drug was involved.
The question before the Court
Could a Kansas man be deported for a misdemeanor conviction for hiding pills in his sock, when Kansas's drug list included some substances not on the federal drug list?
The Court's answer
No — the Court ruled that Mellouli's Kansas paraphernalia conviction did not make him deportable. The federal removal law only applies when a state drug conviction is tied to a substance defined on the federal government's own controlled-substance schedules, and Kansas's law covered several drugs the federal government doesn't regulate while never requiring proof of which drug was actually involved.
The Court rejected both the immigration agency's rule that treated paraphernalia offenses more harshly than drug possession offenses, and the government's broader argument that any drug crime in a state with mostly-overlapping drug schedules should count. Both readings stretched the statute's text — which specifically requires a link to a federally defined controlled substance — further than Congress intended.

Why it matters
Immigrants convicted of minor state drug-paraphernalia crimes — often low-level charges without even a right to a lawyer — can no longer automatically be deported unless the government proves the offense involved a substance the federal government actually controls. This closes a gap where paraphernalia convictions were treated more harshly for immigration purposes than actual drug possession or sale convictions.
What changes now
The Eighth Circuit's judgment is reversed, meaning Mellouli's removal was not authorized by the statute as applied. The ruling is a final merits decision, not temporary. Immigration judges and the Board of Immigration Appeals must now apply the same substance-specific standard to paraphernalia convictions that they already applied to drug possession and distribution convictions, ending the disparate treatment the Court identified.
What this does not decide
The Court did not decide what happens when a state's paraphernalia or drug statute could be split apart so that court records reveal exactly which drug was involved (the "modified categorical approach"), because the government did not argue that theory in this case.
Concurrences and dissents
Dissent — Justice Thomas
Justice Thomas argued the majority ignored the statute's plain text, which asks only whether the state law of conviction 'relates to' a federally controlled substance, not whether the conviction necessarily involved one. Because Kansas's paraphernalia law overwhelmingly regulates federally controlled drugs, he would have held it 'relates to' such substances and affirmed the deportation, regardless of which specific pills were in the sock.
How the Court got there
The legal reasoning, step by step
- The Court applied the categorical approach, the long-standing method for deciding whether a state conviction triggers deportation by looking only at what the state law necessarily required to convict — not at the specific facts of what the person actually did.
- Under this approach, a drug conviction only makes someone deportable if the state law of conviction is limited to substances that appear on the federal government's own controlled-substance schedules; since Kansas's paraphernalia law covered several drugs not on the federal list and never required proof of which drug was involved, the conviction did not necessarily involve a federally controlled substance.
- The Court found that treating paraphernalia convictions differently from drug possession and distribution convictions — deporting people for concealing a drug in a sock but not for possessing that same drug — made no coherent sense and could not have been what Congress intended.
- Because the immigration agency's paraphernalia-specific rule produced this inconsistent result, the Court declined to give it deference under the framework courts normally use to defer to agency interpretations of ambiguous statutes.
- The Court also rejected the government's broader theory that any drug crime in a state whose drug schedules largely overlap the federal list should count, reasoning that this reading stretched the statute's text — which specifically ties deportation to substances defined in the federal drug schedules — far beyond what Congress wrote.
