Authoritative or Institutional writings meaning

In legal practice, “authoritative” or “institutional writings” refers to the classic treatises of certain historic Scottish jurists that courts may rely on to state or clarify Scots law when no binding precedent or statute resolves the point. Recognised in case law (rather than defined by legislation) as a minor formal source of Scots law, these writings—principally Stair’s Institutions, Bankton, Erskine, Bell (Principles and Commentaries) and Hume on Crimes—carry weight beyond ordinary academic commentary. They are given effect where the proposition is clear, consistently supported across the writers, accords with long practice, and has not been displaced by later authority or legislation. Courts most often use them to fill gaps, confirm doctrine, or interpret earlier authorities, particularly in property, obligations and criminal law. Modern textbooks and articles, while often persuasive, are not “institutional writings”. Jurisdictional note: the concept is distinctive to Scotland. In England & Wales, Northern Ireland and Ireland, legal texts (for example, Blackstone or modern practitioners’ works) are persuasive only and do not constitute a formal source of law. These writings are frequently cited in the Court of Session and the High Court of Justiciary.
