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 federal judge in New Hampshire issued a nationwide block Thursday on President Donald Trump’s attempt to end birthright citizenship, just weeks after the Supreme Court lifted similar orders as too broad.
