Kennedy v. Mendoza-Martinez
The Supreme Court struck down two federal laws that automatically stripped citizenship from Americans who left the country, or stayed abroad, to avoid the draft. The Court ruled that losing your citizenship this way was really a criminal punishment in disguise, and the government had imposed it without a trial, a jury, or any of the other protections the Constitution requires before punishing someone.
The decision restored citizenship to a Mexican-American man who had fled to Mexico during World War II and to a doctor who stayed in England and then Czechoslovakia rather than report for the Korean War-era draft. It also produced an influential multi-factor test, still used today, for deciding when a supposedly civil penalty is actually punishment requiring criminal-trial safeguards.
“the Constitution protects against invasions of individual rights, it is not a suicide pact”
Explaining that citizenship obligations, like military service, remain enforceable even as rights are protected.
How it got here: Both men sued for declarations that they remained citizens; lower federal courts ruled in their favor on constitutional grounds, and the government appealed directly to the Supreme Court.
The Case in Depth
What happened
Mendoza-Martinez, born a U.S. citizen, fled to Mexico in 1942 to dodge the World War II draft, later served a prison sentence for draft evasion, and years afterward was told he had lost his citizenship. Cort, a doctor with no other nationality, stayed in England and then Czechoslovakia rather than report for induction during the Korean War era, and was denied a passport on the theory that he had automatically forfeited his citizenship by remaining abroad to evade service.
The question before the Court
Could Congress take away a person's American citizenship for leaving the country, or staying away, to dodge the draft, without ever giving that person a criminal trial?
Why it matters
The ruling meant these two men kept their U.S. citizenship despite having evaded military service, and it barred the government from using automatic denationalization as a shortcut around criminal trials for draft dodgers living abroad. More broadly, it gave courts a lasting checklist for spotting when Congress has dressed up a punishment as a civil regulation, affecting later cases far beyond citizenship law.
What changes now
The judgments of the district courts, which had already ruled for Mendoza-Martinez and Cort, were affirmed, meaning both men retained their U.S. citizenship. Because the Court struck down the underlying statutes as unconstitutional punishments, the sections could no longer be used to automatically denationalize anyone for fleeing the draft; Congress would need to provide criminal-trial protections to pursue such penalties. This was a final merits ruling, not a temporary order.
What this does not decide
The Court expressly said its holding did not disturb earlier decisions allowing Congress to strip citizenship for non-punitive reasons, such as marrying a foreigner or voting in a foreign election, because those laws lacked the same clear punitive purpose. It also did not need to resolve whether the war power or foreign-affairs power alone could have justified these particular statutes.
Concurrences and dissents
Concurrence — Justice Brennan
Justice Brennan agreed that the statutes were unconstitutional punishment, but wrote separately to argue more broadly that Congress may only strip citizenship where doing so is uniquely necessary to solve a genuine nationality-related problem, not as a general-purpose sanction to punish or deter disfavored conduct. He rejected Justice Stewart's morale-boosting rationale as itself just another form of punishment, and argued the foreign-affairs and sovereignty rationales offered by the government also failed.
Concurrence — Justice Douglas
Justices Douglas and Black joined the Court's opinion in full but noted separately that they continued to hold the broader view, expressed in their earlier Perez v. Brownell dissent, that Congress has no power at all to strip a native-born citizen of the citizenship guaranteed by the Fourteenth Amendment.
Dissent — Justice Harlan
Justice Harlan, joined by Justice Clark, agreed with most of Justice Stewart's dissent that the statutes were constitutional, but disagreed on one point: he thought the evidentiary presumption in the 1952 statute was constitutionally valid and, in any event, was not actually relied upon by the district court in Cort's case, so he would uphold denationalization in both cases.
Dissent — Justice Stewart
“As with all syllogisms, the conclusion is inescapable if the premises are correct.”Stewart's opening critique of the majority's reasoning that denationalization here was unconstitutional punishment.
Justice Stewart, joined by Justice White, argued the statutes were not punishment at all but a rational regulatory response to a wartime morale problem, distinguishable from the 1865 desertion law and supported by Congress's war powers. He would have upheld the core provisions but struck down, as irrational, the separate presumption that any violation of compulsory-service laws proves an intent to evade the draft.
How the Court got there
The legal reasoning, step by step
- The Court framed the central question as whether automatically stripping citizenship for draft-evasion flight was actually a criminal punishment, because if it was, the Constitution required a trial with a jury, notice, and counsel before it could be imposed.
- To decide whether a sanction counts as punishment, the Court applied a multi-factor test asking things like whether the measure restrains or disables a person, whether history has treated it as punishment, whether it requires proof of guilty intent, whether it serves retribution or deterrence, and whether it targets conduct already treated as a crime.
- The Court traced the direct ancestor of these laws to an 1865 Civil War statute that Congress itself, in floor debates and later legislative reports, repeatedly and explicitly called a 'penalty' and 'punishment' for desertion and draft evasion.
- Examining the 1944 and 1952 statutes at issue, the Court found the same retributive purpose in the legislative record — Congress focused only on punishing draft dodgers, with no separate regulatory goal like managing foreign relations or troop morale identified in the debates.
- Having found conclusive evidence that the statutes were punitive rather than regulatory, the Court held it unnecessary to separately weigh Congress's war powers or foreign-affairs powers, because a punishment imposed without a criminal trial is unconstitutional regardless of which power supports it.
