A federal appeals court in Boston ruled on Friday that the Trump administration cannot withhold citizenship from children born to people in the country illegally or temporarily. This addition to the growing legal challenges against the president's birthright policy signifies a reaffirmation of established citizenship rights under the Constitution.

A three-judge panel from the 1st U.S. Circuit Court of Appeals became the fifth federal court to uphold decisions blocking the president's birthright order since June. The panel determined that the plaintiffs have substantial grounds to argue that children described in the order are entitled to birthright citizenship based on the Citizenship Clause of the 14th Amendment.

The court upheld lower court rulings that issued preliminary injunctions to halt the enforcement of Trump's birthright order, which aimed to prevent automatic citizenship for babies born to non-citizens in the U.S.

The court highlighted historical precedents, warning against altering established legal frameworks that recognize birthright citizenship. The 'lessons of history' thus give us every reason to be wary of now blessing this most recent effort to break with our established tradition of recognizing birthright citizenship, the court stated.

California Attorney General Rob Bonta, a key advocate against the order, welcomed the ruling, stating, The President’s attack on birthright citizenship flagrantly defies the Fourteenth Amendment of the U.S. Constitution and a nationwide injunction is the only reasonable way to protect against its catastrophic implications.

The legal battles began after Trump signed an executive order on his first day in office, seeking to redefine citizenship parameters, which has since attracted various lawsuits across the country. The 14th Amendment's Citizenship Clause has historically confirmed that all individuals born or naturalized in the U.S. are citizens, regardless of their parents’ immigration status.

The legal discourse surrounding this issue may soon escalate to the Supreme Court, where challenges against such executive powers will be closely scrutinized in the upcoming months.
