In short, SCOTUS told federal district judges that they could still block Trump's birthright citizenship order from going into effect nationwide if they followed "proper legal procedures" in a national class action case. That is what Laplante did in this case. He blocked Trump's order in a well-reasoned ruling that was well-grounded in Rule 23.

A federal judge again blocked President Donald Trump’s administration from implementing his executive order limiting birthright citizenship. The ruling does so through an exception for class action lawsuits in the recent Supreme Court decision that found federal courts do not have the power to issue “universal” injunctions.

Attorneys for President Donald Trump told a federal district judge Monday that a request to turn an immigrants' lawsuit into a class-action suit is little more than an attempted "end-run around" the Supreme Court and should be rejected.
