In an opinion issued last week, a U.S. appeals court affirmed a lower court opinion that upheld actions by the Office of the United States Trade Representative (USTR) in relation to tariffs imposed on Chinese imports during the first Trump administration. The court opinion has direct consequences for these specific tariffs, but several of the legal issues that were argued in this case are likely to come up in the lawsuit against the IEEPA tariffs as well (which will be heard by the Supreme Court in the coming months), and this opinion is of interest for thinking about how those issues might apply in the IEEPA case.
