Pugin v. Garland
The Supreme Court ruled that a state criminal conviction can qualify as an 'obstruction of justice' offense — triggering mandatory deportation under federal immigration law — even if the crime did not require an active investigation or court proceeding to exist at the time.
The decision resolves a split between federal appeals courts and expands the category of state crimes that can make a noncitizen an 'aggravated felon' subject to removal with little ability to seek relief.
“Individuals can obstruct the process of justice even when an investigation or proceeding is not pending. For example, a murderer may threaten to kill a witness if the witness reports information to the police. Such an act is no less obstructive merely because the government has yet to catch on and begin an investigation.”
The majority explains why obstruction of justice does not require an active investigation or proceeding to be underway.
How it got here: Two noncitizens ordered removed as aggravated felons challenged those orders in the Fourth and Ninth Circuits, which reached opposite conclusions; the Supreme Court took both cases to resolve the split.
The Case in Depth
What happened
Fernando Cordero-Garcia, a Mexican citizen, was convicted in California for dissuading a witness from reporting a crime to police. Jean Francois Pugin, a citizen of Mauritius, was convicted in Virginia for being an accessory after the fact to a felony. Federal immigration authorities sought to deport both men as "aggravated felons" whose convictions involved offenses "relating to obstruction of justice." The central dispute was whether that label applies only when the underlying crime requires an active investigation or court proceeding to already be underway.
The question before the Court
Can a noncitizen be deported for a state crime classified as "obstruction of justice" even if that crime did not require any ongoing investigation or court proceeding to be underway when it was committed?
The Court's answer
Yes — the Court ruled that a state criminal offense can qualify as "relating to obstruction of justice" under the immigration law's aggravated-felony definition even if the crime could be committed without any investigation or court proceeding being open at the time. The majority surveyed dictionary definitions from 1996, federal obstruction statutes, state laws, and the Model Penal Code — all of which show that obstructing justice includes interference with the legal system before a formal investigation begins, such as threatening a witness to prevent them from ever calling the police.
The Court rejected the argument that only offenses matching the classic federal obstruction statute — which courts have read to require a pending proceeding — should count. Because Congress used the deliberately broad phrase "relating to obstruction of justice" rather than cross-referencing any specific statute, the majority read that language to cover a wider range of offenses with a genuine connection to impeding the justice system, and found no basis for applying the rule of lenity given the statute's clarity.

Why it matters
Noncitizens — including lawful permanent residents — with convictions for crimes like intimidating a witness or discouraging someone from reporting a crime, even when no investigation was open at the time, may now face mandatory deportation as "aggravated felons," with very limited ability to seek mercy or other forms of immigration relief.
What changes now
The Fourth Circuit's ruling in Pugin's case stands, so his removal may proceed. The Ninth Circuit's ruling in Cordero-Garcia's case is sent back for reconsideration under the correct legal standard — meaning his dissuading-a-witness conviction will now be evaluated as a potential obstruction-of-justice offense. Going forward, immigration courts and federal appeals courts across the country will apply this ruling when deciding whether state or federal convictions qualify as obstruction-related aggravated felonies, though many questions about which specific offenses qualify remain open.
What this does not decide
The Court did not decide whether either noncitizen's specific conviction actually qualifies as a categorical match for generic obstruction of justice — only that crimes need not require a pending proceeding to potentially qualify. Many questions about what affirmative features an offense must have to count under the provision remain unresolved.
Concurrences and dissents
Concurrence — Justice Jackson
Justice Jackson agreed with the majority's conclusion but wrote separately to flag a different possible basis for the decision: when Congress wrote 'offense relating to obstruction of justice' into the immigration law in 1996, it may have been referencing Chapter 73 of Title 18 — the specific cluster of federal statutes Congress itself had labeled 'Obstruction of Justice' — rather than directing courts to construct a generic definition from scratch. Because Chapter 73 contains offenses that do not require a pending proceeding, this framework would reach the same result. Jackson reserved the question for a future case where parties directly argue it.
Dissent — Justice Sotomayor
Justice Sotomayor argued the majority gets the categorical approach backward: rather than identifying the core features of generic obstruction of justice, the majority expands the category to swallow offenses that sit at its edges. Historical sources — from early American statutes through the omnibus clause of 18 U.S.C. § 1503 — show that obstruction of justice has always required a pending investigation or proceeding. The federal witness-tampering statute (§ 1512) expressly waives that requirement precisely because the background rule demands it, proving the rule rather than defeating it. Sotomayor would also resolve any remaining ambiguity in favor of the noncitizen, given the severe deportation consequences at stake.
How the Court got there
The legal reasoning, step by step
- The Court applied the 'categorical approach' — the standard method for deciding whether a prior conviction qualifies as an aggravated felony under the Immigration and Nationality Act (INA). Under this method, courts look only at the legal elements of the crime as written, not what the person actually did, and compare those elements to the 'generic' (commonly understood) definition of the offense category.
- To define generic 'obstruction of justice,' the Court surveyed dictionary definitions from around 1996 (when Congress added the provision to the INA), federal criminal statutes, state laws, and the Model Penal Code. Across all of these sources, the Court found no consistent requirement that an investigation or court proceeding be pending at the time the obstruction occurs.
- Several federal obstruction statutes in Chapter 73 of Title 18 — the section of the U.S. Code headed 'Obstruction of Justice' — explicitly cover conduct even when no official proceeding is pending. The federal witness-tampering statute (18 U.S.C. § 1512) goes so far as to state directly that 'an official proceeding need not be pending or about to be instituted at the time of the offense.'
- The Court rejected the argument that the classic federal obstruction statute (18 U.S.C. § 1503) — which courts have read to require a pending proceeding — should set the definition for the whole category. Congress could have simply cross-referenced § 1503 in the immigration law but chose not to, and many other federal and state obstruction offenses plainly lack that requirement.
- The Court found additional support in Congress's use of the phrase 'relating to obstruction of justice' — broader language than a bare reference to 'obstruction of justice' — which signals that the statute reaches offenses having a meaningful connection to impeding the justice system, not only offenses that precisely match any single statute's elements.
- Because the traditional tools of statutory interpretation pointed clearly in one direction, the Court declined to invoke the rule of lenity — the interpretive principle that ambiguous laws should favor the person facing punishment. That rule applies only when serious ambiguity remains after exhausting other interpretive tools, and the Court found none here.
