Commentary: Examining Trump’s Use of the Alien Enemy Act: Legal Ambiguities, Immigration Battles, and the Erosion of Checks and Balances

The Trump administration’s invocation of the Alien Enemy Act of 1798—a relic of the Adams era designed to authorize the detention, deportation, or imprisonment of non-citizens from nations deemed hostile during wartime or invasion—has ignited fierce legal and political debate. Critics argue the move stretches the law far beyond its original intent, exploiting its vague language to advance hardline immigration policies while testing the resilience of constitutional checks and balances.
Legal Ambiguities: Wartime, “Invasion,” and the Scope of Executive Power
The Act’s application hinges on two narrow conditions: a “declared war” or an actual “invasion” of the U.S. (as defined under international and domestic law). Neither condition is met today. The U.S. is not in a formally declared war, nor is there evidence of an “invasion” akin to a foreign military incursion. Yet the administration has framed undocumented migration—particularly from Central America—as an existential threat, conflating border crossings with “invasion” rhetoric. Legal scholars warn this semantic stretch risks normalizing emergency powers for non-emergencies, setting a dangerous precedent for future executive overreach.
Who Are the Targets? Due Process and the Risk of Overreach
The administration’s focus on alleged members of Tren de Aragua, a Venezuelan gang, raises urgent questions about due process. Under the Alien Enemy Act, the government must demonstrate that detainees are both non-citizens and affiliated with a hostile entity. However, the law lacks clear procedural safeguards, allowing for broad-brush detentions without individualized evidence. Advocates warn that migrants—many fleeing violence—are being wrongfully labelled “gang members” based on tenuous criteria (e.g., tattoos, unverified tips). Without judicial review, such designations risk becoming arbitrary, violating the Fifth Amendment’s guarantee of due process.
Judicial Review vs. Executive Defiance: A Constitutional Stress Test
The administration’s decision to sidestep pending legal challenges—effectively ignoring courts by proceeding with deportations—marks a stark escalation in its battle against judicial oversight. Historically, the judiciary has served as a check on executive power in immigration cases, notably reining in Trump’s travel ban and family separation policies. Yet here, the White House appears to prioritize speed over legality, betting that rapid removals will outpace litigation. This strategy not only undermines the principle of judicial review but also invites a constitutional crisis: If the executive branch can unilaterally ignore courts, what stops future presidents from suspending rights in the name of national security?
Political Calculus: Public Opinion Over Legal Legitimacy
The White House’s willingness to court controversy is no accident. Polls consistently show Trump’s immigration rhetoric resonates with his base, with approval ratings on border issues outperforming his handling of the economy. By framing targets as “gang members” and “criminals,” the administration paints detainees as unsympathetic figures, galvanizing public support while deflecting scrutiny of legal abuses. This political theatre serves a dual purpose: It energizes voters ahead of an election and pressures courts to align with populist sentiment. As one former DOJ official noted, “They want the fight, not the win—because the fight itself reinforces their narrative of a besieged nation.”
Broader Implications: Democracy and the Rule of Law
The administration’s actions expose vulnerabilities in America’s legal framework. The Alien Enemy Act, rarely invoked since World War II (when it targeted Germans, Italians, and Japanese Americans), lacks modern safeguards against abuse. Its deployment today highlights how archaic statutes can be weaponized to evade contemporary legal standards. Moreover, the defiance of judicial oversight signals a troubling shift toward authoritarian governance, where executive power expands at the expense of legislative and judicial constraints.
Conclusion: A Precedent With Peril
While the immediate battle centres on immigration enforcement, the stakes are far greater. If the courts fail to curb this misuse of the Alien Enemy Act—or if the administration continues to bypass rulings—the episode could embolden future leaders to exploit similar loopholes, eroding constitutional protections for non-citizens and citizens alike. As legal challenges mount, the question remains: Will checks and balances hold, or will the “invasion” narrative justify the unravelling of due process? In this clash between law and politics, the integrity of American democracy hangs in the balance.
