A federal appeals court allowed President Donald Trump’s most sweeping tariffs to remain in effect on Tuesday while it reviews a lower court decision blocking them on grounds that Trump had exceeded his authority by imposing them.

The decision by the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. means Trump may continue to enforce, for now, his “Liberation Day” tariffs on imports from most U.S. trading partners, as well as a separate set of tariffs levied on Canada, China and Mexico.

The appeals court has yet to rule on whether the tariffs are permissible under an emergency economic powers act that Trump cited to justify them, but it allowed the tariffs to remain in place while the appeals play out.

The Federal Circuit said the litigation raised issues of “exceptional importance” warranting the court to take the rare step of having the 11-member court hear the appeal, rather than have it go before a three-judge panel first. It scheduled arguments for July 31.

The tariffs, used by Trump as negotiating leverage with U.S. trading partners, and their on-again, off-again nature have shocked markets and whipsawed companies of all sizes as they seek to manage supply chains, production, staffing and prices.
