In a pivotal legal development, U.S. District Court Judge Joseph Laplante of New Hampshire has issued a classwide injunction effectively pausing the enforcement of former President Donald Trump’s executive order that would terminate birthright citizenship for children born in the United States to certain non-citizen parents. This move comes only weeks after the Supreme Court curtailed the use of so-called nationwide injunctions, forcing lower courts and advocates to creatively defend constitutional rights against sweeping federal policies.

The Trump administration’s efforts to undo birthright citizenship—an established principle enshrined in the 14th Amendment—have drawn heated debate, legal battles, and significant national attention since the outset of this year. Legal experts now see Judge Laplante’s order, which certifies a nationwide class encompassing current and future children affected by the executive order, as a key test of how courts confront executive overreach after the Supreme Court’s Trump v. CASA ruling.

Shifting Legal Tactics After Supreme Court Rulings

In June 2025, the U.S. Supreme Court, in a decision with far-reaching consequences, sharply limited lower courts’ ability to issue nationwide injunctions that block federal policies from coast to coast. The move was widely seen as a victory for Trump’s legal team, which has repeatedly challenged the growing use of such injunctions by district courts. But in its 6-3 ruling in Trump v. CASA, the Court left open a crucial pathway: class-action lawsuits, which, if certified, can extend protection to all class members nationwide.

Judge Laplante seized upon this opening in his recent ruling by granting class certification to a group of immigrant mothers and their children, expanding coverage to any baby born on or after February 20, 2025, to mothers without legal status and fathers who are not U.S. citizens or lawful permanent residents. The class also includes women lawfully in the U.S. on temporary visas, such as tourists or students. Effectively, this means the judge’s injunction, though not “universal” in name, blocks application of the executive order for all affected families across the country.

“Judge Laplante is doing exactly what the Supreme Court contemplated,” noted Elora Mukherjee, clinical law professor at Columbia University and director of the school’s Immigrants’ Rights Clinic. She and others caution, however, that class actions are more procedurally demanding, requiring courts to assess whether all members fit the class and have legitimate standing.

One major issue raised in the Laplante case is whether children who have not yet been born can be protected under the class certification. The court found they should—since harm would occur immediately at birth were the executive order enforced. The Department of Justice disagrees, arguing that extending protections to “future persons” would contravene due process. This legal debate is set to play a prominent role as the case moves forward, with the DOJ given a week to appeal Laplante’s ruling before the injunction takes effect.

The Broader Legal Fallout: Precedents and Implications

This battle over birthright citizenship is not occurring in a vacuum. During Trump’s prior term, the administration pursued aggressive immigration rollbacks through executive action and regulatory changes, many of which were challenged in court. According to the Cato Institute, the administration issued more than 400 immigration-related executive actions between 2017 and 2021, dramatically altering policy landscape and legal expectations.

Efforts to revoke birthright citizenship have consistently faced bipartisan opposition from legal scholars, with the vast majority agreeing that the 14th Amendment’s Citizenship Clause guarantees citizenship to all born on U.S. soil, regardless of parental status. Census Bureau figures show that roughly 300,000 children are born annually in the U.S. to undocumented immigrant parents—a population that would have been gravely affected by the now-paused executive order.

The Supreme Court’s ongoing deliberation on the role of lower courts in national policymaking—especially regarding immigration—has major implications, as similar tactics might be employed in future presidential administrations. Both prominent Democrats and Republicans are closely watching how class actions might serve as the new mechanism for nationwide relief in civil rights cases.

Lingering Confusion Over Deportation Practices to El Salvador

While the courts scrutinize the birthright citizenship policy, related controversies have erupted over the Trump administration’s deportations of Venezuelan and Central American migrants to El Salvador earlier this year. Notably, Kilmar Abrego Garcia, a Maryland father of Salvadoran descent, gained widespread attention after being deported to El Salvador’s notorious CECOT prison for over three months, reportedly suffering abuse and severe weight loss before his eventual return to the U.S.

Garcia’s lawyers continue to battle with federal authorities over his status. Earlier this month, conflicting statements from the Department of Justice and Immigration and Customs Enforcement (ICE) revealed a lack of clarity on whether Garcia could be deported once more, and if so, to which country. A Department of Homeland Security official testified that Garcia would face a “credible fear interview” and possible removal to a third country if released from pretrial detention, but was unable to specify details, underscoring confusion and a lack of clear policy guidance.

This uncertainty has put the spotlight on broader due process concerns for immigrants in similar situations. In Garcia’s case, newly released court documents allege physical abuse and neglect while in Salvadoran custody, fueling calls for increased legal protections and oversight.

International Tensions and Accountability in Mass Deportations

Adding to the legal turmoil, a recently surfaced document submitted to a U.N. human rights inquiry contradicts the Trump administration’s assertion that it has no jurisdiction over Venezuelan and other migrants sent to El Salvador. According to the Salvadoran government’s formal response, the U.S. maintains legal custody over the migrants, with El Salvador merely providing prison facilities as part of an international agreement.

The American Civil Liberties Union (ACLU) and other legal groups representing deported migrants see this disclosure as a game changer. Lee Gelernt, lead ACLU attorney on the suit, stated, “We are pleased that El Salvador publicly told the truth about what we all knew: that it’s the United States that controls the fate of the Venezuelans. That the United States did not provide us or the court with this information is extraordinary.”

U.S. District Judge James E. Boasberg, currently overseeing the migrants’ class-action lawsuit, has ordered the government to facilitate habeas corpus rights for those deported under questionable circumstances. The case has drawn attention from human rights advocates and international organizations concerned about the use of the Alien Enemies Act—an 18th-century law invoked by Trump—to justify mass deportations outside established legal norms.

Looking Forward: Continued Legal and Policy Uncertainty

As legal challenges escalate and scrutiny mounts over past and current immigration enforcement tactics, analysts predict prolonged litigation and possible Supreme Court intervention on multiple fronts. Political divisions remain stark: supporters of Trump’s measures argue for stronger national security and immigration controls, while critics highlight constitutional and humanitarian breaches.

For now, Judge Laplante’s classwide injunction has halted a key plank of post-Trump immigration policy, but the ultimate fate of both the executive order and the migrants subject to sudden removals will likely be decided in the higher courts. The battles playing out in district and appellate courts have become the new front line in America’s immigration debate, with potentially millions of lives—both present and future—caught in the balance.
