"Without Precedent": Lisa Graves on the Supreme Court, Tariffs, Voting Rights & Legacy of John Roberts

The Supreme Court heard oral arguments this week in a case challenging President Donald Trump's tariffs, with plaintiffs arguing that his unilateral levies on imported goods violate the Constitution, which grants Congress the power to impose taxes and regulate foreign commerce. The Trump administration has justified his unprecedented use of tariffs under a 1977 law known as the International Emergency Economic Powers Act, but several justices seemed highly skeptical of that argument, potentially putting President Trump's signature economic policy at risk.

There is no genuine emergency. There is no war that is the precipitating basis for invoking IEEPA. And even if it were, it would not allow the imposition of tariffs," says legal expert Lisa Graves, founder of True North Research and co-host of the podcast Legal AF.

Graves also discusses her new book, Without Precedent: How Chief Justice Roberts and His Accomplices Rewrote the Constitution and Dismantled Our Rights.
