About this Event

The Institute of Transnational Commercial Law is delighted to announce it's second seminar for the ITCL Lecture Series:

Trade Usages in Sales Law: Professor Djakhongir Saidov, Professor of Commercial Law, King's College London


In this presentation, Professor Djakhongir Saidov will explore the concept of a trade usage in sales law. A trade usage in sales law can be defined as a pattern of behaviour or a norm developed by business persons that results in standardising governance of sales transactions. By recognising a trade usage, commercial law seeks to give effect to the needs and expectations of the commercial community and to align itself with commercial reality. Despite this significance attached to trade usages, Professor Saidov takes the view that trade usages are in decline as the trading communities increasingly rely on industry sources that are much more formalised, detailed and comprehensive than fragmented trade usages. Drawing on the experience of the UN Sales Convention, English law and the US Uniform Commercial Code, this presentation will demonstrate a number of shortcomings in the way courts and arbitration tribunals worldwide have dealt with the preconditions for the applicability of a trade usage. It will be argued that there is a real danger that sales law has been promoting a ‘fiction’ or ‘phantom’ trade usages. Professor Saidov will advocate limited scope for the legal concept of a trade usage in international sales.
