The arbitration contract is sometimes described as a "myth", a "supposed contract", and sometimes even as "evidence". In fact, the arbitration contract is "an enigmatic phenomenon" that never ceases to fascinate and raise questions among both academics and arbitration practitioners. This contract, which dates back to antiquity, has only received the interest it deserves in recent years, when doctrine and jurisprudence have given it prominence. Today, however, the contract is being called into question by a critical thesis as to its usefulness and even existence. However, it does exist, and its usefulness is not in doubt. This book examines the arbitration contract in the light of various doctrinal theories, based on Tunisian and comparative law.
