Another federal judge has blocked President Trump’s order to end birthright citizenship for the children of illegal immigrants, marking the third one to do so since a major Supreme Court decision in June.

U.S. District Judge Leo Sorokin, an Obama appointee, sided with more than a dozen states and said their nationwide injunction remains valid despite the recent limits the Supreme Court placed on nationwide rulings,

The states say the order is unconstitutional and threatens their budgets by stripping children of the citizenship benefits tied to health and social services.

Sorokin agreed, rejecting the administration’s attempt to narrow the ruling and saying a patchwork of enforcement wouldn’t work because people move between states.

He also criticized the government’s legal argument, saying they had failed to explain how their proposal would be workable or legal.

“That is, they have never addressed what renders a proposal feasible or workable, how the defendant agencies might implement it without imposing material administrative or financial burdens on the plaintiffs, or how it squares with other relevant federal statutes,” Sorokin wrote.
