A CUSMA chapter 10 binational panel essentially takes the place of a court in the first instance under U.S. law. That court is the U.S. Court of International Trade. The CUSMA panel, which is formed with three members from one country and two members from another, essentially steps into the shoes of the U.S. court and determines whether or not the U.S. Department of Commerce's determinations are supported by substantial evidence, or otherwise, in accordance with U.S. law.
If they are not—if the CUSMA panel finds there is insufficient evidence to support the U.S. findings or that they run afoul of U.S. statutes or regulations—the panel will remand the decision back to the U.S. Department of Commerce for correction.
It's a type of judicial review under U.S. law. There may be a series of determinations and remands between the panel and the U.S. Department of Commerce before we have a final outcome.
