Why the Supreme Court Tariff Case Is Such a Big Deal

President Trump’s weekend spree shows how unlimited his claim of power is.

WSJ editorial. Excerpts:

"he has claimed is his power in an “emergency” under the International Emergency Economic Powers Act. But what emergency? Greenland isn’t under threat of invasion, and Denmark has said the U.S. can have more or less free run of the island for defense purposes."

"how open-ended Mr. Trump’s claim of tariff emergency authority is."

"he can use tariffs essentially whenever he wants for whatever reason he wants. Congress gave him no such expansive power under IEEPA or any other statute.'

"'the taxing power is Congress’s under the Constitution unless expressly delegated to the President."
