In a June 27 ruling, the Supreme Court granted the Trump administration’s request to partially halt nationwide injunctions blocking President Donald Trump’s executive order ending birthright citizenship for certain people born in the U.

Friday’s decision limits the circumstances under which the court can issue nationwide injunctions — orders that stop a federal law or policy from being enforced while court battles play out.

Effective immediately, the Trump administration can begin planning for how it would implement an end to birthright citizenship.
