Argentina, et. al. v. United States
Several countries challenged measures found in the United States' Omnibus Budget Reconciliation Act of 1993 that affected the importation, internal sale, and use of tobacco. The Panel concluded that measures requiring that a minimum specified proportion of tobacco be supplied from domestic sources and subjecting imported tobacco to an internal tax or charge in excess of that applied to like domestic tobacco were inconsistent with U.S. obligations under GATT.
