Legal Problem Solving with IRAC

IRAC is a reasoning sequence rather than a decorative structure. The issue must be narrow enough for the governing rule to answer. The rule should be drawn from correct authority and broken into elements, conditions, definitions and exceptions. Application compares legally significant facts with those parts of the rule, including the strongest competing characterisation.

The conclusion follows at the level justified by the analysis.

Problem questions contain background, ambiguity and missing facts. Sort the narrative by legal element instead of retelling it chronologically. State what a missing fact would change rather than supplying an assumption.

Where statutory language is contested, integrate text, context and purpose into the rule and application.

The most valuable sentence often begins with because. It explains why a fact satisfies, weakens or leaves an element unresolved. Without that bridge, a paragraph can contain accurate rules and facts yet still lack legal analysis.

Apply a fictional obstruction bylaw

Q [6 marks]. This 6-point IRAC drill was authored by AskSia; its allocation is not an official university marking scheme. A switched-off electric trolley stands beside a wide entrance for three minutes. The bylaw covers a powered device that materially obstructs movement. How should IRAC work?

The cycle connects issue, rule, application and conclusion, with counterargument at the centre to test whether the first characterisation survives.
  • 1Separate the meaning and obstruction issues.
  • 1Identify definitions and the governing standard.
  • 2Use design, position, width and flow as relevant facts.
  • 1Test the strongest opposing construction.
  • 1State a conditional result where facts are missing.
The issues are whether the trolley remains a powered device when switched off and whether its position materially obstructed movement. A definition and statutory purpose may control the first question. Passage width, pedestrian flow and actual interference bear on the second. Short duration does not erase obstruction, though it affects the factual assessment. The conclusion should remain conditional if the bylaw's definition or available clearance is unknown.
Sia tip — Pair each contested element with one fact and one sentence explaining the inference.

FAQ

Legal Problem Solving with IRAC FAQ

Why is a broad issue a problem?

A broad issue invites a rule dump and makes relevant facts hard to select. Frame the disputed element, duty or statutory word so the rule can answer it. Separate multiple issues when they depend on different authority or facts.

What should go in the rule section?

State the authoritative test, elements, definitions, exceptions, burden and any interpretive qualification needed for the issue. Keep case-specific facts for application. Cite the source that establishes each proposition rather than presenting the rule as unsupported knowledge.

How do I make application analytical?

For each contested element, identify relevant facts, explain the inference and address the strongest competing characterisation. Words such as because, therefore and however can reveal the bridge, but the substance must show why the fact matters legally.

What if the problem omits a decisive fact?

Do not invent it. State how each possible fact affects the rule and identify the information needed. Give a conditional conclusion whose confidence matches the uncertainty. This is stronger than certainty built on an unstated assumption.

Can one paragraph contain more than one IRAC cycle?

Yes, when a larger issue contains linked elements, but each cycle must remain visible. State the controlling proposition, apply the facts bearing on that proposition and reach an interim conclusion before moving on. If rules and facts become tangled, split the paragraph and use descriptive subheadings.

How can I test whether my conclusion is properly qualified?

Trace every qualification back to a genuine uncertainty: disputed fact, ambiguous text, competing precedent, discretion or missing information. Remove vague hedging that has no analytical source. A bounded conclusion should still identify the likely result and the condition that could change it, rather than merely saying that anything is possible.

Study strategy

Exam move

Practise one-paragraph IRAC before writing full answers. Use one issue, one structured rule, two competing facts and a bounded conclusion. Underline the sentence that connects fact to element.

If no such sentence exists, the paragraph is descriptive rather than analytical.

Create an error ledger with categories for overbroad issue, unsupported rule, missing element, irrelevant fact, one-sided application and overconfident conclusion. After each practice response, rewrite the weakest category only.

This makes improvement visible and avoids repeatedly drafting complete answers with the same flaw.

During planning, allocate facts to elements and note missing information. Write the strongest opposing inference beside your preferred one. In the final answer, conclude on each issue before giving the overall result. Preserve uncertainty where discretion, ambiguous text, missing facts or competing authority remains.
