In less than two weeks, two extraordinary elements of the Donald Trump legal saga will collide — the battle to bring down Trump’s tariffs, and the Trump administration’s fight to prevent judges from blocking his policies across the country.

The Court of International Trade is set to hold oral argument on May 13 in one of the growing number of cases that challenge the bulk of the Trump tariff regime. The lawsuits, which are strong on the merits, argue that the tariffs are not legally authorized under the International Economic Emergency Powers Act, the law that Trump has invoked.

At issue is a motion for a preliminary nationwide injunction to put a stop to the tariffs filed by the Liberty Justice Center, which is representing a New York-based alcohol importer and distributor known as V.O.S. Selections, along with four other small businesses that say the tariffs could decimate their companies.

Just one wrinkle: Two days later, the Supreme Court will consider whether to crack down on judges’ power to check the administration in precisely this way. The justices will hear oral argument in the Trump administration’s request to overturn a series of nationwide injunctions currently halting Trump’s executive order to end birthright citizenship.
