Certificate of Customary Law
The program of the certificate
Facing most legal questions, it seems necessary to complement the classic legal analysis based on statutes and cases with a reference to usages. Ignoring them creates a worrying blind spot for the documentation. On the contrary, paying attention to customary Law opens a gold mine of arguments and improves the legal services on a national and even more at an international level.

An expertise gathered in a book
Une forte coopération s’est créée entre l’Université de Berkeley et l’Institut des usages avec notamment la co-direction de l’ouvrage “Customary Law Today” (Ed. Laurent MAYALI et Pierre MOUSSERON, Springer 2018.)
Ce livre traite des pratiques actuelles du droit coutumier. Il comprend des contributions de chercheurs de divers systèmes juridiques (États-Unis, France, Israël, Canada, etc.), qui examinent les impacts actuels du droit coutumier sur divers aspects du droit privé, du droit constitutionnel, du droit des affaires, du droit international et du droit pénal. En outre, le livre élargit le concept traditionnel de l’état de droit et soutient que les avocats ne devraient pas se concentrer uniquement sur le droit statutaire, mais devraient plutôt accorder plus d’attention à l’impact des pratiques sur la «vraie vie juridique». Il déclare que l’observation des pratiques exige une concentration plus forte sur l’usage, les coutumes et les traditions dans nos systèmes juridiques – l’idée n’étant pas de remplacer le droit statutaire, mais de le compléter par des observations coutumières.
A strong cooperation has been created between Berkeley Law and l’Institut des usages (IDU) with, in particular, the co-editing of the book “Customary Law Today” (Ed. Laurent MAYALI and Pierre MOUSSERON, Springer 2018.)
This book addresses current practices in customary Law. It includes contributions by scholars from various legal systems (the USA, France, Israel, Canada etc.), who examine the current impacts of customary Law on various aspects of private Law, constitutional Law, business Law, international Law and criminal Law. In addition, the book expands the traditional concept of the rule of Law, and argues that lawyers should not narrowly focus on statutory Law, but should instead pay more attention to the impact of practices on “real legal life.” It states that the observation of practices calls for a stronger focus on usage, customs and traditions in our legal systems – the idea being not to replace statutory Law, but to complement it with customary observations.
