John Jackson bestrode the world of international trade law like a Colossus. His 1969 treatise on World Trade and the Law of GATT was called the bible of GATT law. His 1977 casebook on Legal Problems of International Economic Relations created a new law school course and introduced thousands of students around the globe to international trade law. It was the leading international trade law casebook for decades, and his students went on to positions of responsibility throughout the world in governments, international organizations, and private practice. His analysis of GATT infirmities convinced certain influential governments to push for a new international trade organization, which eventually saw life as the World Trade Organization. It was a great honor for me to have been associated with John for over thirty years. Indeed, his 1985 invitation to join as a co-author of the casebook after my first year in law teaching undoubtedly saved me many years of drudgery as a corporate/securities law scholar. Thus, I am pleased to offer some thoughts on John's influence on dispute settlement under GATT and the WTO.
