What IRAC actually is — and what it isn't
IRAC stands for Issue, Rule, Application, Conclusion. It's a four-stage analytical framework that mirrors how courts actually reason: identify the legal issue, state the relevant rule, apply that rule to the facts, then reach a reasoned conclusion. Done well, IRAC produces clear, methodical legal writing that examiners can mark quickly and confidently.
Done badly, IRAC produces something worse than free-form writing — a robotic, formulaic essay that loses marks for being too rigid. The framework is a tool, not a script. Strong law students use IRAC to structure their analysis; weak students use it to replace their analysis.
The other thing to understand: IRAC isn't always the right framework. Some UK law schools teach ILAC (Issue, Law, Application, Conclusion) — essentially identical, just a different name for the second stage. Others teach CREAC (Conclusion, Rule, Explanation, Application, Conclusion) which front-loads your answer. Your module handbook will name the framework your faculty expects. Use that one. Substituting an unfamiliar variant — even a defensible one — costs marks.
For most UK undergraduate law modules, IRAC or ILAC is standard. The rest of this guide covers IRAC, but the principles transfer.
The four stages — with worked examples
The examples below use a hypothetical contract law problem: a buyer (B) attempts to revoke acceptance after a seller (S) has shipped goods, and we need to determine whether a binding contract was formed. This is the kind of fact pattern that appears constantly in first-year contract problem questions.
Two common errors here. First, students restate the facts ("B sent S an order, then tried to cancel it") instead of identifying the legal issue ("Did B's revocation reach S before acceptance was complete under the postal rule?"). Second, students identify too broad an issue ("Was there a contract?") when the actual disputed question is much narrower ("When did acceptance take effect under the postal rule?").
A well-formulated issue is specific enough that the rest of your analysis flows logically from it. If you can't see how to apply a rule to the question you've stated, the issue is too broad. Refine it.
Cite primary sources first. Cases come before secondary commentary. Adams v Lindsell establishes the rule; Cheshire, Fifoot & Furmston's Law of Contract explains it. Cite the case in your rule, save the textbook for support if needed. UK law school markers expect to see ratios from cases, not paraphrases of textbook chapters.
Where the rule has been refined or qualified by later cases, include that. Holwell Securities v Hughes (1974) shows that the postal rule doesn't apply where the offer specifies that acceptance must be received. A complete rule statement includes both the principle and the relevant qualifications.
Use the language of legal reasoning. "The facts here are analogous to Adams v Lindsell in that…" or "This case can be distinguished from Holwell Securities because…" These are the constructions examiners look for. They demonstrate that you understand the rule isn't applied mechanically — it's applied through reasoning by analogy.
Address counterarguments. A First-class application doesn't just present the case for one side — it considers what the strongest counterargument would be, then explains why it fails. "B might argue that the postal rule should not apply because… However, this argument is weak because…" Examiners reward students who anticipate the other side.
Apply the rule, don't just restate it. The most common mistake at this stage is paraphrasing the rule again. If your application section reads like a slightly reworded version of your rule section, you're not applying the law — you're describing it.
Your conclusion should answer the issue you identified in stage one. Read your issue, then read your conclusion. Do they match? If your issue asked when acceptance was complete, your conclusion needs to answer when acceptance was complete — not summarise the cases or restate the rule.
Where the law genuinely is uncertain, say so — but explain why. "On the better view, B's revocation was ineffective because…" is far stronger than "It is unclear whether B's revocation was effective." Confidence in legal writing comes from reasoning, not from absence of doubt.
IRAC in problem questions vs essay questions
IRAC is built for problem questions — fact patterns where you apply the law to determine an outcome. For traditional essay questions ("Critically evaluate the postal rule's continuing relevance in the digital age"), IRAC needs adaptation.
For an essay question, your "issue" is the question itself. Your "rule" is a survey of the relevant doctrine. Your "application" is your critical analysis — how well does the doctrine work, what are its limitations, what reform proposals exist. Your "conclusion" is your evaluative position.
Many UK law schools prefer that you don't use rigid IRAC headings in essay questions. Instead, integrate the IRAC logic into a flowing essay structure: introduction (issue), doctrinal exposition (rule), critical analysis (application), conclusion. The thinking is the same; the presentation is more academic.
Check your module conventions. Some lecturers explicitly mark you up for using IRAC headings even in essay questions. Others mark you down. There's no universal rule — the rule is your specific module's expectations.
OSCOLA referencing — the part that catches everyone out
OSCOLA (Oxford Standard for Citation Of Legal Authorities) is the referencing system used by virtually every UK law school. It's distinctive because it uses footnotes rather than in-text citations, and because the formatting rules for cases are very specific.
The basics for cases: Case Name [Year] Volume Reporter Page. So Donoghue v Stevenson [1932] AC 562 means the case of Donoghue v Stevenson, decided in 1932, reported in volume AC (Appeal Cases) at page 562. Note: square brackets when the year is essential to finding the case (modern reports), round brackets when it isn't (older reports).
For statutes: Sale of Goods Act 1979, s 14(2). No need to italicise. Section symbol is "s" lowercase, not "§" or "Section".
For journal articles: Andrew Burrows, 'Legislative Reform of Remedies for Breach of Contract' [1997] LMCLQ 67. Note: square brackets, journal abbreviation, page number.
The trap most students fall into: using neutral citations and law report citations interchangeably. A neutral citation ([2023] UKSC 14) is the court's official version. A law report citation ([2023] 1 AC 567) is the published report. OSCOLA expects you to give the neutral citation first, followed by the most authoritative law report. For most UK supreme court and appellate cases since 2001, this means two citations separated by a comma. Older cases just need the law report.
If your law essay's footnotes don't follow OSCOLA precisely, you lose marks for presentation regardless of how strong your analysis is. SafeGrade's citation checker handles OSCOLA formatting alongside Harvard and APA — run your footnotes through it before submission. The errors that get flagged are the ones markers actually penalise.
5 mistakes that drop your law essay grade
1. Stating rules without authorities. Every legal proposition needs a source. "Acceptance is complete on posting" is wrong; "Acceptance is complete on posting (Adams v Lindsell 1818)" is right. Even rules that seem obvious need citations — examiners assume you don't know it if you don't cite it.
2. Treating the rule section as a textbook summary. Your rule section should be the legal rule, not a chapter summary. "Lord Atkin's neighbour principle from Donoghue v Stevenson establishes the modern law of negligence, which has subsequently been refined by…" loses focus. The rule is what the case established. Save the development for application.
3. Application that doesn't apply. The most common 2:2-grade mistake. Students restate the rule, then say "applying this to the facts, the contract is binding" — without showing the working. Application means demonstrating why the rule produces the outcome. Show your reasoning step by step.
4. Hedging in the conclusion. "It could be argued that B is liable, but it could also be argued that B is not liable, so the outcome is unclear" is what a student writes when they don't want to commit. Examiners want commitment. Take a position. Defend it.
5. Mixing up obiter and ratio. The ratio decidendi is the binding part of a case — the legal reasoning necessary for the outcome. Obiter dicta are observations made along the way. Treating obiter as binding authority is one of the fastest ways to lose marks at any level. If you cite a case for a proposition, make sure that proposition is actually part of the ratio.
What separates a 2:1 law essay from a First
A 2:1 law essay correctly identifies the issues, states the relevant rules with proper authority, applies them competently to the facts, and reaches a reasoned conclusion. That's what IRAC done well looks like — and that's the upper second-class standard.
A First-class law essay does something more. It engages critically with the rule itself. It notices when authorities point in different directions and explains why. It identifies tensions, ambiguities, and policy considerations that a competent application would gloss over. Where appropriate, it gestures toward reform — not as undergraduate speculation, but grounded in academic commentary or Law Commission proposals.
The technical difference often shows in the application stage. A 2:1 application says "applying this rule to these facts produces this outcome." A First-class application says "applying this rule to these facts produces this outcome, but the rule itself is open to criticism on the following grounds, and a more nuanced approach — as suggested by the Law Commission's 2018 consultation — would produce a different result that better reflects modern commercial practice."
This isn't showing off. It's demonstrating that you understand law as a living, contested practice rather than a fixed set of rules to be applied. That's the move from 2:1 to First — and it's available to anyone willing to read beyond the prescribed reading list and engage with the academic debates around the doctrine.
