The ruling keeps a block on the Trump administration from denying citizenship to children born to people who are in the United States illegally or temporarily.

A three-judge panel of the U.S. Ninth Circuit Court of Appeals has agreed with a lower court’s ruling that President Donald Trump’s executive order seeking to redefine birthright citizenship is unconstitutional.

The court ruled that a nationwide injunction is the only way to provide complete relief to the state government plaintiffs in the case.
