Last month, the Supreme Court limited the use of nationwide injunctions, which allow judges to block policies they have found unlawful from going into effect nationwide. Now a New Hampshire judge is road-testing a substitute: He has temporarily blocked Donald Trump’s birthright citizenship executive order by certifying a class action to cover babies born in all 50 states.

A federal judge again barred President Donald Trump's administration from enforcing his executive order limiting birthright citizenship nationwide after the Supreme Court restricted the ability of judges to block his policies using nationwide injunctions.

A New Hampshire judge issued a ruling pausing President Donald Trump's executive order to end birthright citizenship. He also certified a class action lawsuit on behalf of children who would be affected by the president's order.
