The appellants sought judicial review of a decision by the Canadian Import Tribunal, which found that the subsidization of U.S. grain corn caused material injury to Canadian producers.
The Tribunal interpreted the Special Import Measures Act (SIMA) in light of the GATT Subsidies Code, considering potential imports as well as actual imports.
The Federal Court of Appeal dismissed the applications for judicial review.
The Supreme Court of Canada dismissed the appeals, holding that the Tribunal's interpretation of its constitutive legislation was not patently unreasonable and that it was appropriate for the Tribunal to consult the GATT in interpreting SIMA.
