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 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.
