En Banc Fifth Circuit Dismisses Alien Enemies Act Case as Moot After All Three Plaintiffs Were Deported Under a Different Law
The full appeals court said it no longer had a live dispute in W.M.M. v. Trump, leaving unanswered whether President Trump may use the 1798 Alien Enemies Act against alleged Tren de Aragua members.
Three Men, One Missing Case
On August 13, 2026, the full U.S. Court of Appeals for the 5th Circuit threw out one of the biggest legal fights over President Trump's immigration powers. The case, W.M.M. v. Trump, had asked whether the president could use an 18th-century wartime law to fast-track deportations of alleged gang members [1][2]. The court didn't answer that question. It said it no longer could.
The reason was simple and strange at once. All three men who brought the case were already gone. The government had deported them while the case was still pending — just not under the law being challenged [2][4].
That single fact is why nobody agrees on what just happened. Depending on who you ask, this was either a clean win for the administration, a dodge by the court, or an outrage in progress. All three readings come from the same 18-page order.
The Law, the Gang, and the Men Who Left
The dispute traces back to March 15, 2025, when Trump signed Proclamation 10903 [3][11]. It invoked the Alien Enemies Act of 1798, a law written for wartime, against Venezuelan nationals the administration says belong to Tren de Aragua. The State Department has designated that gang a foreign terrorist organization [3].
The 1798 act matters because of what it skips. Normal deportation runs through immigration court, a process that can take months or years. The wartime law lets the government bypass most of that and remove people fast [3][10]. That speed is exactly why the administration wants it, and exactly why opponents are fighting it.
In March 2025, the government used the proclamation to remove more than 100 Venezuelan nationals it accused of gang ties [4]. Three of the men swept up in that effort sued from Texas, arguing the law doesn't apply to them. The Supreme Court kept their case alive by sending it back to the 5th Circuit while all three were still in the country [4].
Then, while the appeal was pending, the government deported all three anyway. This time it used the ordinary Immigration and Nationality Act, not the 1798 law [2][3]. A case built around three specific men no longer had any of them left inside the United States.
Why a Court Can Lose the Right to Rule
Federal courts can only decide live disputes between real people — a rule known as mootness. Chief Judge Jennifer Walker Elrod's opinion says that once removal happens, there is no one left for the court to help. "We conclude that the appeal is moot," she wrote [4].
There is normally an escape hatch for exactly this situation: a certified class action. If a court has formally recognized a group of plaintiffs as a class, the case can survive even after any single member's circumstances change [8][2]. That protection didn't apply here, because no class had ever been certified in this case.
Elrod's opinion left the door open for that to change. The district court, she wrote, remains free to revisit class certification going forward [8][2]. Until that happens, the same pattern could repeat: the government removes whoever is challenging the law, and the challenge disappears with them.
This is the pressure sitting underneath the whole case. A court dismissal that erases a lower ruling is called vacatur, and it reset the legal scoreboard here. A 5th Circuit panel had ruled in September 2025 that illegal migration and drug smuggling don't count as an "invasion" under the 1798 act [3][12]. That ruling no longer binds anyone, because the case it came from is gone [8][1].
A Justice Who Wanted an Answer Anyway
Not every judge on the panel was content to stop at mootness. Judge James Ho, a Trump appointee, wrote a separate concurrence arguing the court should have reached the merits [8][9]. His argument reaches past this one case.
Courts, Ho noted, never second-guess a congressional declaration of war by asking whether the war is real. He argued the same logic should apply to a president's declaration of invasion: total deference, no judicial review [8][9]. If courts followed that reasoning, a president's national-security judgment about who counts as an invading force would be effectively unreviewable.
Critics see real stakes in that idea. Groups including the Cato Institute argue that "invasion" in 1798 meant an armed attack by a foreign state, not the activities of a criminal gang [10][8]. Stretching the term that far, they warn, would let any president declare an emergency and deport people by proclamation, with no court able to check the decision [10].
The administration's broader argument is about who gets to decide, not just this one case. Judging whether a foreign group's activity inside the country amounts to an "invasion" is a foreign-affairs call, in its view — the kind the Constitution gives to the president, not to judges [8][9]. On the dismissal itself, the administration's position is simpler: the parties are gone, so the case is gone, and that's how courts are supposed to work [2][4].
What the Injunction Still Blocks
The ACLU, representing the deported men, reads the outcome very differently. Lead counsel Lee Gelernt points out that a Supreme Court order restraining Alien Enemies Act removals out of that Texas district is still in effect [7]. In that specific district, the administration still can't use the law, regardless of what happened to this case [7].
The ACLU also notes that most courts to actually reach the merits of the question have ruled against the administration [7]. From that vantage, nothing about the underlying legal fight has moved. What changed is that a favorable appellate precedent vanished along with the plaintiffs who won it.
That raises the strategic question the ACLU is most worried about. If deporting the named plaintiffs under a different law can end a case before any court rules, the government could in theory keep a contested power in reserve indefinitely, without ever having to defend it on the merits [3][10]. Getting a class certified would close that gap by giving the case plaintiffs the government can't remove one by one.
Reading the Same Order in Different Countries
None of this is disputed as a matter of what happened. The disagreement is over what it means, and coverage split largely along those lines. Fox News and RedState framed the dismissal as a win that keeps the law available to the administration, with RedState's "goes poof" headline treating a jurisdictional ruling as if it settled the merits [1][5]. Neither outlet gave much weight to the fact that the Supreme Court's injunction in Texas is still standing [7].
NBC News and The Hill went the other way, describing the court as "dodging" or "skirting" the central question of presidential power [7][11]. Those verbs cast a mootness ruling, a routine and long-established limit on what courts can decide, as something closer to evasion. Courthouse News Service stuck closest to the court's own language, quoting Elrod directly, though its headline word "dooms" overstates how final the outcome really is, since class certification is still on the table [2][8].
Overseas coverage tells a different story mostly by what it leaves out. Al Jazeera's most-shared Alien Enemies Act article covers the September 2025 panel ruling that went against Trump, not the August 2026 reversal of it [14]. A reader relying on that coverage could easily still believe the 5th Circuit has blocked the policy outright, when the legal ground has since shifted.
What's Left Standing
Strip away the framing, and the confirmed facts are narrower than any single side's version. The court said it lacked a live case. It said so because the three named plaintiffs were gone. It left the class-certification question for the trial judge to take up next [8][2].
Three men are outside the United States, removed under ordinary immigration law rather than the 1798 act that started their case [2][3]. No federal appeals court has yet settled whether the wartime law can be used against a criminal gang in peacetime [8][1]. The Supreme Court's order limiting removals out of that Texas district remains in force in the meantime [7].
The fight now heads back to district court, where the question of whether to certify a class will determine whether a future challenge can survive the next round of deportations [8][2]. Until that happens, the central question in W.M.M. v. Trump — whether a president's declaration of invasion is something a court can review at all — remains exactly where it was before the ruling: unanswered.
Summary
On August 13, 2026, the full 5th U.S. Circuit Court of Appeals threw out a major challenge to President Trump's use of the Alien Enemies Act of 1798. It did not say whether the president's use of the law was legal. It said it could no longer decide the question at all[1][2][3].
The case, W.M.M. v. Trump, was brought by three Venezuelan men held in Texas. They said the government planned to deport them under the 1798 wartime law as alleged members of the gang Tren de Aragua. While the case was pending, the government deported all three anyway — but under ordinary immigration law, not the 1798 act[2][3][4]. Chief Judge Jennifer Walker Elrod wrote that with no named plaintiff left in the country, there was nobody the court could give relief to. "Given this change, we conclude that the appeal is moot," she wrote[4].
The sides read the same order very differently. The Trump administration and its supporters call it a clean win: the challenge is gone, and an earlier appeals-court ruling against the policy is wiped away with it[1][5][6]. The ACLU, which represents the men, says nothing important changed — the Supreme Court's order blocking Alien Enemies Act removals out of that Texas court is still in place, and lower courts that have reached the merits have mostly ruled against the administration[7][3].
The genuine dispute is not really about these three men. It is about whether a court can review a president's decision that the country faces an "invasion." Judge James Ho, a Trump appointee, wrote separately that the court should have answered that question and held that the president's judgment is not reviewable at all[8][9]. Critics say that would hand any president a peacetime deportation power with no judicial check[7][10].
The Event
On August 13, 2026, the en banc 5th U.S. Circuit Court of Appeals dismissed W.M.M. v. Trump as moot[1][2]. The case challenged President Trump's March 15, 2025 proclamation invoking the Alien Enemies Act of 1798 against Venezuelan nationals the administration says belong to Tren de Aragua[3][11]. All three named petitioners had been removed from the United States under ordinary immigration law rather than under the 1798 act[2][4]. Chief Judge Jennifer Walker Elrod wrote that with no named petitioner left to grant relief to, and no class ever certified, the appeal was moot[4][8].
Undisputed Facts
- President Trump issued Proclamation 10903 on March 15, 2025, invoking the Alien Enemies Act of 1798 against Venezuelan nationals the administration identified as Tren de Aragua members[3][11].
- The State Department had designated Tren de Aragua a foreign terrorist organization[3].
- In March 2025 the administration removed more than 100 Venezuelan nationals accused of gang ties[4].
- The Supreme Court sent the case back to the 5th Circuit while the three named petitioners were still in the United States[4].
- A 5th Circuit panel ruled in September 2025 that illegal migration and drug smuggling do not amount to an 'invasion' or 'predatory incursion' under the act[3][12].
- The full 5th Circuit reheard the case en banc in January 2026 and issued its dismissal on August 13, 2026[7][1].
- The government removed all three named petitioners under the Immigration and Nationality Act, not under the Alien Enemies Act[2][3].
- The en banc court held that the class-action exception to mootness did not apply because no class had ever been certified in the case, and said the district court remains free to revisit class certification[8][2].
The Pressure
Strip away the moralizing and blame. What structural realities persist regardless of which narrative wins?
- Speed versus process
- Ordinary deportation runs through immigration court and can take months or years. The Alien Enemies Act, if it applies, lets the government skip most of that. That speed is the whole point of invoking it — and the whole reason opponents fight it[3][10].
- Mootness as a strategic tool
- A court can only hear a live dispute. If the government removes the named plaintiffs under a different law, the challenge to the first law can collapse before any judge rules on it. That works whether or not anyone intends it. It is why the plaintiffs' side now needs a certified class — a group of people the court formally recognizes as parties, so the case survives even when any one member's situation changes[8][2].
- Vacatur resets the scoreboard
- When an appeal is dismissed as moot, the ruling below usually loses its force as precedent. So the September 2025 panel holding that gangs are not an 'invasion' no longer binds anyone in the 5th Circuit. The administration gains not by winning the argument but by making the loss disappear[8][12].
- A statute with almost no case law
- The Alien Enemies Act has been used only three times in U.S. history, all during declared wars — the War of 1812, World War I, and World War II. There is very little precedent telling courts what 'invasion' or 'predatory incursion' means outside a declared war[3][10].
Material realityThree Venezuelan men are out of the United States, removed under ordinary immigration law[2][3]. More than 100 Venezuelans were removed in March 2025 under the disputed proclamation[4]. The Supreme Court's order restraining Alien Enemies Act removals from that Texas district is still in effect, so the administration cannot currently use the act there[7]. No federal appeals court precedent now settles whether the invocation is lawful[8][1]. The fight moves back to the district court, where class certification decides whether a challenge can survive future deportations of individual plaintiffs[8][2].
Narrative as a weaponThree groups are actively shaping how this reads. The administration and right-leaning outlets want you to see a win — the challenge dismissed, the adverse ruling erased, the tool intact. The ACLU wants you to see a technicality — the injunction still standing, the merits still going its way in most courts, nothing decided. Judge Ho, writing only for himself, wants you to see a court that ducked: he argues the merits question should have been answered, and answered in the president's favor with total deference. All three descriptions can be quoted accurately from the same 18-page order. The verifiable core is narrower than any of them: the court said it lacked a live case, said so because the named plaintiffs were gone, and said the trial judge may revisit the class question. Everything past that is prediction.
How Each Side Sees It
Each major actor’s view — how it frames things, its underlying incentive, and how it’s materially affected. Tap a side to read it.
Frames it asThe administration's core argument is about who decides. Deciding whether a foreign armed group's operations inside the country amount to an 'invasion' or a 'predatory incursion' is a foreign-affairs and national-security judgment, they say — the kind the Constitution gives the president, not judges. Judge James Ho put the strongest version of this in his concurrence: courts never look behind a congressional declaration of war to ask whether the war is real, so there is no principled basis for second-guessing a presidential proclamation of invasion either[8][9]. On the procedure, the administration says mootness is not a trick. Article III courts decide live disputes between real parties. When the parties are gone, so is the case[2][4].
WhyKeep the Alien Enemies Act available as a fast-track removal tool that skips the immigration-court process, and avoid a binding appellate precedent saying the invocation was unlawful[3][12].
Impact on themThe dismissal also wipes out the September 2025 panel ruling that had gone against the administration, so no circuit-level precedent now blocks the theory in the 5th Circuit[8][1]. But the Supreme Court's order restraining removals under the act out of that Texas district remains in place[7].
Frames it asTheir first argument is about the practical effect: nothing was lost. The Supreme Court's injunction still bars Alien Enemies Act removals in the relevant district, and courts that have actually reached the merits have mostly said using a wartime law in peacetime is unlawful, according to lead counsel Lee Gelernt[7]. Their second argument is about incentives. If the government can end a case simply by deporting the named plaintiffs under a different law, it can keep a contested power alive forever without ever defending it in court[3][10]. That is the concern behind the 'capable of repetition, yet evading review' exception — a rule that lets courts decide short-lived disputes that would otherwise always end before a ruling[8].
WhyGet a binding appellate ruling that the 1798 act cannot be used against a criminal gang in peacetime, and preserve due-process hearings before any removal under it[7][10].
Impact on themThe three clients are already out of the country[2]. The lawyers must now go back to the district court to try to certify a class, which would give the case a plaintiff the government cannot simply deport away[8][2].
Frames it asThe majority's position is institutional modesty, not evasion. Federal courts have power only over live cases. Chief Judge Elrod wrote that with all three named petitioners gone, there is no one left to grant relief to[4]. The exception for class actions does not help, because no class was ever certified here — and whether one should be is a fact question for the trial judge, not something an appeals court decides first[8][2]. Reaching out to settle a major separation-of-powers question in a case with no live party would be the aggressive move, not the restrained one.
WhyAvoid deciding a politically explosive constitutional question that a deeply divided court might split badly on, and keep the case moving through the normal district-court track[8][5].
Impact on themThe court drew criticism from both directions — from the ACLU for not deciding, and from Judge Ho for not answering questions the Supreme Court had effectively teed up[9][8].
Frames it asRestrictionist analysts, including the Center for Immigration Studies, argue both the panel majority and its dissent misread the act's 18th-century terms, and that the statute's text is broader than critics allow[13]. Libertarian and civil-liberties analysts, including Ilya Somin at the Cato Institute and Reason's Volokh Conspiracy, argue the opposite: 'invasion' in 1798 meant armed attack by a foreign state, and stretching it to cover a criminal gang would let any president declare an emergency and deport by proclamation[10][8]. Both camps agree on one thing — the question is important and is still open.
WhyShape how courts and the public read a statute that has been used only three times before, all during declared wars[3][10].
Impact on themWith no controlling circuit precedent, their arguments carry more weight in the next round of litigation[8].

| Courthouse News Service | U.S. center, legal trade press | 2 | "Mootness dooms challenge to Trump's Alien Enemies Act deportations." | Closest to straight reporting: quotes Elrod's language directly and explains the class-certification point. "Dooms" is the one loaded word, and it overstates finality since the district court can still certify a class. |
| The Hill | U.S. center | 3 | "5th Circuit rules Alien Enemies Act case moot, skirting question on Trump's power." | Leads with the accurate holding, then adds "skirting." Gives the ACLU's response substantial space; the administration's mootness argument gets less room. |
| NBC News | U.S. center-left | 4 | "Appeals court dodges ruling on Trump's use of Alien Enemies Act." | "Dodges" attributes avoidance to the court in the outlet's own voice. A neutral verb — declines, dismisses — would carry the same facts without the implied criticism. |
| Al Jazeera | Qatari state-funded | 4 | Its widely circulated Alien Enemies Act piece — "US court blocks Trump bid to use Alien Enemies Act to deport Venezuelans" — covers the September 2025 panel ruling, not the August 2026 dismissal. | The omission is the tell. The substantive loss for Trump drew heavy overseas pickup; the procedural reversal of that ruling drew far less. Readers relying on foreign coverage may still believe the policy is blocked by the 5th Circuit. |
| Fox News | U.S. right | 5 | Frames the dismissal around Trump's 'fight' over the 18th-century deportation law surviving 'the latest court clash.' | Casts a jurisdictional dismissal as the policy living to fight another day.

| RedState | U.S. right (opinion-driven) | 8 | "After All That, 5th Circuit's Trump Alien Enemies Act Case Goes Poof." | "Goes poof" and "after all that" treat the outcome as a rebuke to the challengers rather than a limit on the court's own power. Mocking tone substitutes for the mootness reasoning. |
