How to Write a First-Class Law Essay (That Actually Argues)

A sharp, specific guide to the structure, analysis, and habits that separate a 70+ law essay from a competent 58.

Most law essays fail at the same point: they describe the law accurately and then stop. A first-class essay does something harder. It takes a position, defends it against the best counterargument available, and uses cases as evidence for a claim rather than as decoration.

Here is how you get there.

The Single Most Important Shift: Description Versus Argument

Imagine the question is: "The neighbour principle in Donoghue v Stevenson was a radical departure from existing doctrine. Discuss."

A 2:2 answer tells you what Lord Atkin said in [Donoghue v Stevenson [1932] AC 562](https://www.getcaselaw.com/case-library/7c984837-f0b3-4afc-a73f-3ec96f6e4756), summarises the snail-in-a-bottle facts, and explains that the neighbour principle requires reasonable foreseeability of harm. Accurate. Dull. No argument.

A first-class answer asks: was it actually radical? It acknowledges Lord Atkin's synthesis of prior authorities like Heaven v Pender and Le Lievre v Gould, argues that the genius of the neighbour principle was not invention but consolidation, and then concedes that the extension to purely economic relationships (later resisted in Caparo) was the genuinely disruptive move. That is an argument. It has a thesis, evidence, and a countermove.

Before you write a single word of your essay, write one sentence that completes this prompt: "I am going to argue that..." If you cannot do that, you are not ready to write.

Structure: The Answer First, Always

Law essays are not crime novels. Do not hide your conclusion until the end. State your thesis in the introduction, support it in the body, and reinforce it (without just repeating it) as you close. Markers are reading twenty essays in a sitting. Make their job easier.

A reliable skeleton looks like this:

1. Introduction (10% of words). One short paragraph. State what the essay will argue, flag the main tension or controversy you will address, and tell the reader how you will structure the answer. No need to define every term or quote the question back at length.
2. Body sections (80% of words). Each section should make one point, support it with authority, and engage with the strongest objection. If a section cannot be summarised in a single sentence, it is probably two sections.
3. Closing paragraph (10% of words). Return to the thesis. Has it been proved, qualified, or complicated by the analysis? Say which. Do not introduce new material.

The temptation is to spend the introduction clearing your throat: restating the question, defining obvious terms, promising to "examine" things. Cut all of that. Open with the argument.

How to Use Cases Properly

Cases are evidence, not content. The distinction matters.

Using a case as content looks like this: "In Rylands v Fletcher, the defendant employed independent contractors to build a reservoir. Water escaped and flooded the plaintiff's mine. The court held that a person who brings onto their land something likely to do mischief if it escapes is strictly liable." This is encyclopaedia writing. It tells the marker you read the case. It earns you nothing above a solid 2:2.

Using a case as evidence looks like this: "Strict liability in [Rylands v Fletcher [1868] UKHL 1](https://www.getcaselaw.com/case-library/65ecd889-4647-4539-89bf-5ec68f274b) rests on the premise that a defendant who creates an exceptional risk should bear its consequences regardless of fault. The logic is distributive rather than corrective. That is precisely why subsequent courts have felt compelled to restrict the rule rather than extend it: Transco plc v Stockport MBC [2003] UKHL 61 confines 'non-natural use' so narrowly that the rule has become almost academic." See the difference? The case is doing work in an argument.

Practical rules for case use:

• Name the principle before you name the case. State the legal proposition, then attribute it. "The duty of care test requires reasonable foreseeability, proximity, and that it be fair, just and reasonable to impose a duty (Caparo Industries plc v Dickman [1990] UKHL 2)." Not the other way around.
• Use the ratio, not the facts, unless the facts are the point. The facts of Goldman v Hargrave [1967] 1 AC 645 (a burning tree, a landowner who let it smoulder rather than extinguishing it) matter because the Privy Council used them to develop the measured duty of care for occupiers in respect of naturally occurring hazards. See Goldman v Hargrave for the full reasoning. The facts earn their place. Often they do not.
• Engage with dissents and academic criticism. Lord Denning dissented frequently and often presciently. If your essay is about the development of promissory estoppel, ignoring his judgment in Combe v Combe [1951] 2 KB 215 in favour of a bland summary of Central London Property Trust v High Trees House [1947] KB 130 signals that you are paraphrasing a textbook rather than thinking.

Critical Analysis: What It Actually Means

Every law tutor says "be more critical." Few explain what that means in practice.

Critical analysis is not scepticism for its own sake. You do not get credit for calling a judgment "controversial" without explaining why. Critical analysis means identifying the reasoning behind a rule, testing whether that reasoning is internally consistent, and considering what values or policy choices the rule reflects.

Try this three-step move for any legal rule:

1. State what the rule requires and how courts have applied it.
2. Identify the underlying rationale. Is it corrective justice? Economic efficiency? Protection of reasonable reliance? Say which.
3. Test the rule against that rationale. Does the rule actually achieve what it claims to? Are there cases where the rule produces outcomes inconsistent with its own logic?

For example, the loss of chance doctrine in Hotson v East Berkshire Area Health Authority [1987] AC 750 and Gregg v Scott [2005] UKHL 2 is a productive area for this. The House of Lords refused to award damages for a less-than-50% chance of a better medical outcome. The rationale is epistemic: courts should not award compensation where causation cannot be proved on the balance of probabilities. Fine. But Fairchild v Glenhaven Funeral Services [2002] UKHL 22, decided in the same era, allowed recovery where a claimant could not prove which of several defendants had caused his mesothelioma. The courts applied a "material contribution to risk" standard. Are these positions consistent? That tension is exactly what a first-class essay should identify and interrogate.

Answering the Actual Question

This sounds obvious. It is not.

Read the question three times before you plan. Underline the key instruction word: discuss, critically analyse, evaluate, compare. These are not interchangeable.

• "Discuss" asks you to present competing views and reach a reasoned conclusion.
• "Critically analyse" asks you to interrogate the law's coherence, its justifications, its effects.
• "Evaluate" asks you to weigh the law against some standard, often a policy goal or normative principle.
• "Compare" asks you to identify similarities and differences between two rules, cases, or approaches, and usually to reach a view about which is preferable or more coherent.

A common failure mode: a student gets a question asking them to evaluate the Law Commission's proposed reforms to the law of illegality, and writes a thorough description of Patel v Mirza [2016] UKSC 42 without once considering whether the Supreme Court's approach is actually an improvement. The information is good. The task is not done.

Also: answer the whole question. If a problem question has three parties with three separate legal issues, allocate your attention proportionately. Do not spend 80% of your words on the most familiar issue and dash through the others.

The Mechanics That Markers Notice

Signposting

Tell the reader where you are going. Not with filler phrases, but with topic sentences that make a claim. Start each paragraph with a sentence that could stand alone as a proposition: "The courts' restrictive approach to pure economic loss reflects a policy concern about indeterminate liability rather than a principled doctrinal boundary." Then spend the paragraph proving it. A marker should be able to read only the first sentence of each paragraph and follow the argument.

Citation Format

For assessed coursework, follow whatever citation style your institution specifies (OSCOLA is standard in the UK). For exams, abbreviated citations are fine: case name, year, and court. What is not fine is citing a case with no citation at all, or getting the year wrong. If you are not sure whether it was 1991 or 1992, write "early 1990s" or just rely on the principle without the date.

Hedging and Overconfidence

Avoid both extremes. Do not say "the law is clear that..." when the law is contested. Do not say "it could be argued that..." when it is your own view and you have evidence for it. Own your argument. "The better view is..." or "The preferable interpretation is..." signals confidence without false certainty.

Sentence-level writing

Legal writing should be precise, not ornate. Short sentences land harder than long ones. When you do use a longer sentence, make sure every clause is earning its place. Read your draft aloud. If you run out of breath or lose the thread, the sentence is too long.

Avoid passive constructions where possible. "It was held by the court" is weaker than "The court held." Active voice keeps the reader oriented.

Planning and Drafting: A Process That Works

Here is a concrete process, not a vague suggestion:

1. Read the question. Identify the issues. Write them down as a list, not prose.
2. Write your thesis sentence. One sentence. Controversial enough to need defending.
3. Plan the body. Three to five sections. Each section gets a one-sentence summary of its point.
4. Identify the cases and statutes for each section. Do not reach for a case unless it directly supports the point in that section.
5. Write a rough draft without stopping. Do not edit as you go. Get the argument down.
6. Revise for argument, then for prose. First pass: does each paragraph actually advance the thesis? Cut anything that does not. Second pass: is the writing clear and precise?

For timed exams, compress this. Spend 10 minutes planning. Write a one-sentence thesis at the top of your plan so you do not drift. The plan is worth its weight: students who skip it tend to write themselves into corners and then pad.

One Habit That Separates Good Students From Very Good Ones

Read the academic commentary, not just the cases. Law journals are not optional extras for postgraduates. Articles by scholars like Andrew Burrows on unjust enrichment, or Conaglen on fiduciary duties, or Stapleton on causation, are precisely what separates a textbook summary from an essay that engages with the intellectual life of the subject. Your reading list points you at these. Use them.

When you cite academic commentary, engage with it rather than quoting it as a badge. "Professor Stapleton argues that the 'but for' test is under-theorised at its foundations (2003). This is persuasive because..." is useful. Dropping a citation at the end of a sentence you never interrogate is not.

Past papers are also underused. Working through a past paper under timed conditions, then comparing your answer against a model, is more valuable than two hours of passive re-reading. You can find past papers with model answers to practise with, which is worth doing before any assessed piece rather than after.
