The US Supreme Court ruled on Friday that nationwide injunctions issued by lower court judges were likely to exceed the judicial branch’s constitutional authority.

This would grant a major boost to President Trump’s push to put an end to birthright citizenship.

The case mostly revolved around the administration’s challenge to several lower courts’ sweeping injunctions against the president’s Day One order. This would be related to overturning the longstanding protection sought from the Constitution of the US.

The Supreme Court failed to address the merits of Trump’s real order in its opinion, only the extent to which one of the nearly 700 district judges in America could block an executive action from coming into play.

At the White House, Trump referred to this ruling as a victory for the Constitution and shared plans to advance the birthright citizenship order, as well as different policies that were blocked by federal courts.

Currently, the government’s applications to partially stay the preliminary injunctions have been granted. But that’s only to the extent that the injections are broader than needed to give full relief to every plaintiff with standing right to sue.
