IRAC vs ILAC: which framework should UK law students use?

If you have encountered both IRAC and ILAC in your LLB reading, the immediate question is which one your lecturers expect and whether it matters in practice. The honest answer: the underlying logic is identical; the structural difference is minor; and your module or institution determines which label to use. Understanding the distinction clearly means you can adapt to either without confusion—and avoid the trap of treating the label as more important than the reasoning it frames.

Where students lose marks is not usually from using IRAC where ILAC was expected. It is from treating the framework as a rigid stencil rather than a discipline for legal reasoning. This guide clarifies the difference and tells you when each label is relevant.

What IRAC and ILAC actually stand for

IRAC: Issue, Rule, Application, Conclusion.

ILAC: Issue, Law, Application, Conclusion.

The difference is that ILAC sometimes breaks Law into two explicit sub-steps—the legal principle and the authority for it—whereas IRAC treats both as part of a single Rule paragraph. Some Australian law schools and a minority of UK programmes use ILAC explicitly. Most UK LLB programmes use IRAC or do not label the framework at all but expect the same sequence.

The structural difference in practice

In ILAC, you might see separate sub-headings or paragraphs for:

• Law (principle): the legal rule or test, stated abstractly.
• Law (authority): the case or statute establishing the rule.

In practice, a well-written IRAC Rule paragraph does both of these in a single section. The distinction is presentational rather than substantive. If your module guidance specifies ILAC, follow it; if it says IRAC or says nothing, you do not need to impose a Law/authority split that your programme has not asked for.

Which framework does UK legal education use?

The large majority of UK LLB programmes, GDL courses, and SQE preparation materials use IRAC or describe the same sequence without naming it. ILAC appears more commonly in Commonwealth jurisdictions and some vocational programmes. If you are studying at a UK university and your module handbook says nothing about ILAC, IRAC is the safe default.

For SQE candidates, the SRA does not mandate either acronym—it mandates clear, structured legal analysis. Both frameworks deliver that; see the SQE legal writing guide for how this applies to SQE2 written tasks.

Where the label matters less than the execution

The examiners who mark UK LLB problem questions are assessing whether you have identified the issue, stated the law accurately, applied it to the facts, and reached a conclusion—in that logical sequence. A student who uses the word "Law" instead of "Rule" in their heading but narrates the facts instead of testing them in Application will score lower than a student who uses IRAC labels correctly and applies them with precision.

The marks-critical skill is Application depth. The Application deep-dive covers this in detail; the IRAC structure guide covers the full framework. Neither depends on which acronym sits at the top of your page.

Practical checklist: IRAC or ILAC, does it hold?

• Does your Issue name the precise legal question the facts raise—not a topic summary?
• Does your Rule (or Law) paragraph state the applicable test with the key authority, proportionately?
• Does your Application explicitly run the test against the facts—not retell the scenario?
• Does your Conclusion resolve the Issue you framed—without new reasoning?

If all four are yes, the label on the framework is immaterial. If any is no, fix that leg—see the step-by-step IRAC essay guide for worked examples at each stage.

What about FIRAC, CREAC, and other variants?

FIRAC adds Facts as an explicit first step—common in case analysis exercises. CREAC (Conclusion, Rule, Explanation, Application, Conclusion) is a US legal writing convention. UK LLB and SQE contexts do not require either. Familiarity with the variants helps if you read US-sourced materials, but for UK assessments, IRAC delivers the structure the marking criteria reward.
