A federal judge appointed under the Biden administration has temporarily blocked President Trump's renewed executive order restricting birthright citizenship, citing the Supreme Court's June ruling that already settled the constitutional question.

U.S. District Judge Deborah Boardman issued a preliminary injunction Wednesday barring enforcement of provisions in Trump's August 6th executive order that sought to deny citizenship to children born on U.S. soil to certain categories of foreign parents. The ruling represents Trump's second failed attempt to limit the longstanding constitutional guarantee that all babies born in America automatically receive citizenship.

Supreme Court Already Decided Issue

Judge Boardman ruled the matter was resolved by the Supreme Court's June 30, 2026 decision striking down Trump's previous sweeping order denying birthright citizenship to children of undocumented immigrants or temporary visitors. The judge emphasized that no presidential executive order can undo what the Supreme Court has done.

Trump's latest order expanded restrictions beyond his initial attempt, denying automatic citizenship not only to children of ambassadors or foreign ministers but to children of other foreign citizens including embassy employees and staff of international organizations like the United Nations and World Bank.

The administration defended a different interpretation of constitutional limits on birthright citizenship. Justice Department lawyers argued the Supreme Court's decision did not establish that all children born to noncitizen parents are citizens without exception, pointing to historical categories such as children of diplomats and certain alien enemies.

Timing and Implementation Questions

The Trump administration argued the lawsuit was premature because federal agencies had not yet issued guidance needed to implement the executive order. However, Judge Boardman found intervention was necessary before those guidelines took effect to prevent constitutional violations.

The judge clarified agencies may still develop guidance on how the government intends to implement the order, but they cannot use it to deny citizenship to children born in the United States. The ruling allows planning to proceed while blocking actual enforcement.

Lawyers for plaintiffs including CASA and Asylum Seeker Advocacy Project argued historically accepted exceptions to birthright citizenship are very limited. They accused the government of attempting to expand those exceptions through executive action rather than the constitutionally required amendment process.

Constitutional Authority Dispute

The birthright citizenship guarantee stems from the Fourteenth Amendment's declaration that all persons born in the United States are citizens. Trump has long argued this constitutional protection should not extend to children of parents in the country illegally or temporarily.

Soon after the Supreme Court struck down his first executive order in June, Trump indicated he would ask the justices to reconsider their decision. Such requests rarely succeed, as the Supreme Court has not agreed to revisit an argued case in decades. The deadline for filing a rehearing petition passed without Trump making the request.

Instead, the president issued his second executive order on August 6th attempting to achieve similar policy goals through narrower restrictions aimed at birth tourism and children of foreign government employees. Civil liberties groups immediately challenged the revised order as another unconstitutional attempt to rewrite citizenship law.

The ACLU's Immigrants' Rights Project warned any executive order trying to rewrite birthright citizenship will meet the same fate as the previous attempt. Constitutional amendments require approval by Congress and state legislatures, a far higher bar than presidential action alone.

The legal battle over birthright citizenship reflects broader immigration policy conflicts between the Trump administration and federal courts. Multiple Trump executive orders on immigration have faced judicial scrutiny, with judges frequently ruling the president exceeded constitutional authority or violated statutory requirements in his policy directives.
