The Institutional Writers

It is tempting to assume that Stair, Erskine, Bankton, Bell, and Hume are simply historical legal commentators — the Scottish equivalent of a well-regarded but ultimately non-binding law school textbook. This understates their status. In Scots law, a small, closed group of historic legal treatises are treated as having the force of an authoritative source of law in their own right — citable in court not merely as persuasive opinion but as something closer to legislation or binding precedent. This "institutional writer" status is rare among common-law-influenced systems and is one of the clearest markers of Scots law's civilian inheritance.

This card applies the series' three-tier framework specifically to the status and content of the institutional writings. It treats as settled the existence of the category itself, the identity of its core members, and the dates of publication of their major works — these are matters of documented legal and bibliographic record. It treats as traditional doctrine the precise boundaries of the category (for example, whether certain borderline figures belong on the list) and the conventional justification for why these particular works were elevated above ordinary legal writing — these rest on long professional consensus rather than a single codifying rule, and different authorities give slightly different lists or rationales. It treats as contested any claim about how much genuine practical authority institutional writings retain in current Scottish litigation, since this is actively debated by legal scholars rather than settled by consensus.

What "Institutional Writer" Actually Means

In most common-law systems, even a brilliant and widely respected legal textbook is formally just persuasive commentary — a court may be influenced by it, but it is not, strictly speaking, a source of law. Scots law treats a small, closed group of historic treatises differently. "Institutional writings" sit in a distinct category, traditionally ranked in authority somewhere between judicial precedent and ordinary academic commentary, and Scottish courts have at times treated statements in these works as settling a point of law in the absence of contrary authority. This status is not granted by statute or by any formal process; it emerged through sustained professional and judicial acceptance over generations, and the list of qualifying writers is now effectively closed — no author since the 19th century has been added to the canon, however influential.

Why This Status Exists — the Civilian Connection

This practice is best understood as a surviving feature of Scots law's civilian inheritance, explored in more depth elsewhere in this series' overview card and its dedicated card on Roman law's influence on Scots law. Continental civilian traditions have long given weight to systematic juristic writing — treatises that organise and explain the law comprehensively — in a way that classical English common law, built primarily around case-by-case precedent, generally did not. Scotland's early lawyers, trained at continental universities such as Leiden, Utrecht, and Paris before Scotland had its own developed university law faculties, brought this respect for systematic treatise-writing home with them. Stair's Institutions (treated in full in its own dedicated card) is explicitly modelled on this continental genre — organising the whole of private law into a coherent system — rather than on the English textbook tradition.

The Core Five (and a Few Near-Misses)

The canon is traditionally centred on five writers. Stair (1681) is foundational and comprehensive, covering the whole of private law; his treatment belongs chiefly to his own dedicated card in this series, so only his role as the originator of the genre is noted here. Andrew McDouall, Lord Bankton (1751–53) produced An Institute of the Laws of Scotland, distinctive for running a systematic comparison alongside English law, reflecting the post-Union environment in which Scots lawyers increasingly had to engage with English legal concepts. John Erskine of Carnock, a professor of Scots law at Edinburgh, wrote An Institute of the Law of Scotland, published posthumously in 1773; it became, for generations, the standard teaching text and remains frequently cited, particularly in property and succession. George Joseph Bell extended the tradition into commercial and mercantile law with his Commentaries (1804) and later the more concise Principles of the Law of Scotland (1829), reflecting Scotland's growing commercial and industrial economy in the early 19th century. David Hume (the advocate and nephew of the philosopher of the same name, not to be confused with him) produced the Commentaries on the Law of Scotland Respecting Crimes (1797), still regarded as the foundational institutional authority specifically on Scots criminal law. A handful of other writers — such as Erskine's own earlier work, or certain 19th-century treatise-writers — are sometimes discussed as borderline or "near-institutional," but the core canon of five is what is generally meant by the term today.

How Institutional Status Is Used in Practice

Institutional writings are deployed somewhat differently from ordinary case citation. Courts have, at various points, used a clear and consistent statement in an institutional writer — especially where case law is sparse, old, or ambiguous — to settle a point of law, effectively filling gaps that direct precedent does not cover. This is most visible today in areas where the institutional writers' subject matter has changed relatively little, such as core property concepts or the structure of the criminal law of homicide (where Hume's Commentaries remain regularly cited). In fast-moving, heavily statute-driven areas — commercial law, company law, much of modern criminal procedure — institutional writings now function more as historical and interpretive background than as a live, load-bearing authority, because statute and recent case law have largely superseded them.

Live Scholarly Debate: How Much Weight Do They Still Carry?

It would be inaccurate to present institutional-writer status as a fixed, unchanging doctrine with the same practical force today as in the 18th or 19th century. Scottish legal scholars disagree, sometimes significantly, about how much genuine interpretive weight courts still give these texts versus treating them as historically important but largely superseded by modern statute and case law. Some scholars argue the institutional writers remain analytically central, particularly for understanding the underlying civilian structure of Scots private law. Others argue their practical citation has become increasingly ceremonial — invoked to lend historical gravitas to a judgment whose actual reasoning rests on modern case law or legislation. This article treats the question as genuinely open rather than asserting a settled answer.

Present-Day Status

The list of institutional writers is, by overwhelming professional convention, closed. No 20th- or 21st-century author — however distinguished, and including the authors of major modern reference works like the Stair Memorial Encyclopaedia (itself named in Stair's honour) — has been added to the canon. This closure is itself notable: it reflects a shift in how Scots law now develops, relying far more on statute, case law, and law reform bodies such as the Scottish Law Commission than on individual systematising treatises. The institutional writers therefore occupy a genuinely historical role today — foundational, still occasionally decisive, but no longer the primary engine of legal development that they were between the 17th and 19th centuries.

• The institutional writer category has been effectively closed for roughly 200 years — no new author has been formally added to the canon since the 19th century.
• David Hume, the institutional criminal law writer, should not be confused with the famous philosopher David Hume — they were relatives (the advocate was the philosopher's nephew) but entirely distinct figures with entirely distinct bodies of work.
• John Erskine's Institute was published after his death in 1773, compiled and edited from his lecture materials as a professor of Scots law at Edinburgh.
• Lord Bankton's Institute is distinctive among the core five for deliberately running a side-by-side comparison with English law — an early, systematic acknowledgment of the post-Union pressure to engage with the other UK legal system.
• George Joseph Bell's institutional status rests specifically on commercial and mercantile law — reflecting how Scotland's rapidly industrialising economy in the early 1800s created demand for authoritative treatment of trade, insurance, and bankruptcy law.
• Institutional writings are sometimes cited by name in modern judgments even today, particularly in property and criminal law, more than two centuries after some of them were written.
• The 1981 tercentenary of Stair's Institutions helped inspire the Stair Memorial Encyclopaedia, a 26-volume modern reference work on Scots law — a direct institutional legacy running from 1681 to the present day.
• Unlike in many civilian systems, Scotland's institutional writings were never consolidated into a single official code; each writer's treatise stands as an independent, if overlapping, authority.

• Wrong: "Institutional writers are just old textbooks with sentimental value." Correct: They hold a formally recognised, distinct authority status in Scots law, historically closer to a source of law than ordinary commentary.
• Wrong: "Any sufficiently respected Scottish legal author can become an institutional writer." Correct: The category has been treated as closed for roughly two centuries; no modern author has been added, regardless of reputation.
• Disputed, not settled: How much genuine practical weight institutional writings carry in 21st-century courts, versus functioning mainly as historical/interpretive background, is actively debated among scholars.
• Wrong: "David Hume the institutional writer and David Hume the philosopher are the same person." Correct: They are different people (closely related), with entirely separate bodies of work.
