Legal method — writing case notes and essays

This note addresses the method of legal analysis — the techniques by which lawyers and judges read, synthesise, and apply authorities. It is not about the substantive content of any doctrinal area (contract, tort, constitutional law), but about the transferable craft skills required to write a persuasive case note or essay. These skills underpin all legal work, from tutorial preparation to finals papers and, eventually, practice.

Legal reasoning depends on identifying rationes, distinguishing precedents, reading statutes closely, and marshalling policy arguments within doctrinal constraints. The structure of your writing — whether a 500-word case note or a 2,000-word essay — must reflect that process with clarity and precision.

This note complements Weeks 1–7, which have introduced sources, precedent, statutory interpretation, judicial creativity, equity, and the law–morality interface. Week 8 consolidates that foundation by teaching you how to demonstrate mastery in written work.

Learning objectives

By the end of this note you should be able to:

• write a concise, analytically rigorous case note;
• structure a tutorial essay that advances a coherent argument;
• identify the ratio decidendi of a judgment and explain its precedential scope;
• use IRAC (Issue, Rule, Application, Conclusion) and analogous frameworks;
• avoid common pitfalls (narrative restatement, unargued assertions, vague 'policy' invocations);
• integrate academic commentary (Dworkin, Hart, Raz, Fuller, Atiyah et al.) appropriately.

The modern conventions of legal writing — case reporting, note-taking, and critical commentary — emerged gradually from the practices of the medieval Year Books, the Inns of Court, and the rise of professional law reports.

The Year Books and early case reporting

The Year Books (c. 1268–1535) recorded moots and arguments in Law French. They were didactic, not systematic: barristers and students used them to learn pleading technique rather than to fix binding precedent. The concept of ratio decidendi was inchoate; judgments were brief, often oracular.

Private reporters (nominate reports: Coke, Plowden, Burrow, etc.) began to record fuller judgments from the sixteenth century. Quality varied; Coke's Reports (1600–15) mixed accurate reporting with his own constitutional agenda (Dr Bonham's Case (1610) 8 Co Rep 113b). The multiplication of private reporters led to inconsistency and unreliability — a problem that persisted into the nineteenth century.

The Incorporated Council of Law Reporting (1865)

The founding of the Law Reports (1865) marked a watershed. Judges began to revise their own judgments before publication; reporting became systematic and reliable. The modern habit of extended, written judgments — which lawyers could parse for ratio and obiter — took hold. Victorian judges (Cairns LC, Blackburn J, Bramwell B) wrote trenchantly; their style influenced generations of legal writing.

Academic commentary — case notes in journals — began in earnest in the late nineteenth century. The Law Quarterly Review (1885) and Harvard Law Review (1887) set the pattern. A.L. Goodhart's article Determining the Ratio Decidendi of a Case (1930) 40 Yale LJ 161 codified what had become implicit practice.

The modern tutorial essay tradition

Oxford and Cambridge tutorial essays inherit this tradition of close reading, synthesis, and critique. The genre assumes that students will master both doctrine (what the law is) and theory (what the law ought to be, and why judges reasoned as they did). This dual focus distinguishes the English law degree from code-based civil law jurisdictions and from many American undergraduate programmes.

1. Precision and economy of expression

Legal writing values concision. Avoid adverbs ('clearly', 'obviously'); if the argument is sound, the conclusion will be self-evident. Avoid hedging unless genuine uncertainty exists ('it is submitted that arguably…'). Never write 'it could be argued' without stating who could argue it and why.

Ambiguity is a vice in legal drafting and exposition. Use terms of art accurately: 'ratio' not 'reasoning'; 'obiter dictum' not 'dicta' when singular; 'overruled' for precedents, 'quashed' for administrative decisions, 'reversed' on appeal.

2. Precedent-based reasoning

Common law reasoning is analogical. You demonstrate legal conclusions by showing that:

• the facts fall within or outside the ratio of a binding precedent;
• the instant case is materially similar to (or distinguishable from) persuasive authorities;
• principles articulated by higher courts govern or guide the outcome.

In an essay, sequence matters. Establish the rule (statute or precedent), identify the material facts, then apply the rule. Do not state your conclusion first and retrofit authority.

3. Identifying the ratio decidendi

Goodhart's method (1930) remains foundational: the ratio is the legal principle (rule + material facts) necessary to the decision. Everything else is obiter. Later courts are bound by ratio but may cite obiter as persuasive.

Difficulties arise when:

• the court gives multiple judgments (especially in the House of Lords / Supreme Court) without a clear majority principle (Young v Bristol Aeroplane [1944] KB 718);
• the judgment is policy-driven and the ratio hard to extract (Anns v Merton LBC [1978] AC 728);
• the court distinguishes on facts you consider immaterial, effectively narrowing an earlier ratio (Hedley Byrne v Heller [1964] AC 465).

Your task is to articulate the ratio clearly, note areas of uncertainty, and acknowledge doctrinal tension candidly.

Foundation (suitable for early Mods practice)

1. What is the ratio decidendi of a case, and how does it differ from obiter dictum? Illustrate with reference to one decided case.
2. Outline the structure of a problem-question answer using the IRAC method. Why is this method preferred in legal analysis?

Standard (typical Mods exam standard)

1. 'The doctrine of precedent values certainty over justice.' Discuss.
2. Compare and contrast how an undergraduate law essay differs from (i) a case note, and (ii) a legal opinion. What are the distinctive features of each genre?

Challenge (for strong candidates)

1. 'Legal reasoning is not syllogistic but analogical, and therefore indeterminate.' Critically assess this claim with reference to at least two of the following: Hart, Dworkin, MacCormick, Goodhart, Schauer.
