Legal experts contend that the Trump administration exceeded its statutory powers by invoking rarely applied laws to justify its wide-ranging immigration crackdown.

The administration’s actions—such as using the 18th-century Alien Enemies Act to deport 238 alleged Venezuelan gang members to El Salvador and attempting to detain a lawful permanent resident under an untested provision of the 1952 Immigration and Nationality Act—may have surpassed its constitutional authority.

Immigration lawyer David Leopold described these moves as “unilateral, factual determinations made by the executive,” suggesting that the administration’s interpretation of these old statutes is vulnerable to judicial reversal. In one instance, U.S. District Judge James Boasberg temporarily blocked deportations under the Alien Enemies Act, arguing that the law was intended to address hostile actions by foreign nations rather than individual cases of alleged gang activity.

The administration’s use of the law that enabled the detention of Columbia student Mahmoud Khalil, a green card holder of Palestinian descent, has also raised concerns. Khalil’s lawyers argue that his arrest was retaliatory for his participation in pro-Palestinian protests and infringes on his First Amendment rights. A similar provision was used only once before—in a 1995 case involving Mario Ruiz Massieu—which was later challenged for its constitutionality.

While the Trump administration has appealed judicial blocks on these deportations, the ultimate question of whether its invocation of these laws is constitutional may end up before the Supreme Court, where a conservative majority currently holds sway. Some experts, however, remain skeptical of the notion that the executive branch possesses unfettered authority in foreign affairs, arguing that such matters remain subject to judicial review.

The controversy underscores the broader legal and political battles over executive power in immigration enforcement and highlights the potential for significant shifts in policy if these challenges reach the highest court.
