The judge also granted the case class-action status after the Supreme Court limited judges' ability to block orders nationwide through other means.

A US judge has once again blocked President Donald Trump from implementing an executive order ending birth right citizenship for some US residents as a legal challenge moves forward. A New Hampshire judge approved a class action lawsuit against Trump's executive order, and temporarily stopped the president's order from taking effect.

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.
