My topic in this article is the role of regulatory purpose under Article III of the GATT, and I regard Bob [Hudec] as the patron saint of efforts to establish the relevance of purpose. His famous "Requiem for an 'Aims and Effects' Test" may have been called a requiem, but it was reluctant and sceptical. Bob thought dispute settlement tribunals ought to consider the regulator's purpose, and he thought they would do so, whatever they said. As decisions on Article III accumulate, we are in the process of learning that he was right on both counts.
