Interesting paragraph from dissenting opinion:

"No right is safe in the new legal regime the court creates. Today, the threat is to birthright citizenship. Tomorrow, a different administration may try to seize firearms from law-abiding citizens or prevent people of certain faiths from gathering to worship. The majority holds that, absent cumbersome class-action litigation, courts cannot completely enjoin even such plainly unlawful policies unless doing so is necessary to afford the formal parties complete relief. That holding renders constitutional guarantees meaningful in name only for any individuals who are not parties to a lawsuit. Because I will not be complicit in so grave an attack on our system of law, I dissent."
