On Friday, the Supreme Court held that federal courts lack authority to issue universal injunctions. The decision in Trump v. CASA deprives the judiciary of a vital tool in checking the most egregious abuses of executive power. But it also does something more pernicious, creating a blueprint for the Trump administration to win by losing.

The Supreme Court has delivered a monumental victory for the Constitution, the separation of powers and the rule of law in striking down the excessive use of nationwide injunctions to interfere with the normal functioning of the executive branch.
