Trade Barriers to the Public Good provides a detailed examination of NAFTA and AIT cases involving MMT — a chemical additive brought into Canada by the US company Ethyl Corporation Inc. When the Canadian federal government banned the importation of MMT under the Fuel Additives Act, Ethyl Corp. filed a claim under NAFTA Chapter 11 seeking US $201 million in damages. Alex Michalos uses a case study of MMT to reveal exactly how and why quasi-judicial international dispute processes provide significantly less protection for the public interest than the routine procedures for passing an ordinary Act of Parliament.
