Ordinary arguments from authority have the following structure: A says p; A is authoritative on such things; so p. Legal actors use such arguments whenever they ground their decisions on the sheer ‘say-so’ of legislators, judges, scholars, expert witnesses, etc. This paper focuses on arguments appealing to the authority of scholars, ‘doctrinal’ or ‘dogmatic’ legal scholars in particular. Appeal to doctrinal authority is a puzzling feature of legal argumentation. In what sense are doctrinal scholars ‘authorities’? Is p, as advanced by a scholar, descriptive or prescriptive? Is scholarly authority grounded on expertise or something different? The paper addresses these questions.
