In history of legal ideas of the last generation in Canada, legal pluralism deserves an important place. There is a Quebec genre in the legal literature on pluralism that, for reasons one might well suspect, is less well-known elsewhere. The scholarship of Professor Jean-Guy Belley, one of the leading figures in the field, is deserving of a wider readership among non francophones. A translation on one of his most important papers, published at a critical moment in his personal development as a scholar, is presented here in the hope of introducing his work to new readers.
