Legal Problem-Solving: IRAC & MIRAT
Topic 4 gives you the two structured methods for answering legal problems: IRAC (Issue, Rule, Application, Conclusion) and the fuller MIRAT (Material facts, Issue, Rule, Argument, Tentative conclusion). This is the single most important technique in the unit — it is the skeleton the 40% Written Assessment is marked against, and choosing between IRAC and MIRAT is how you manage a tight word limit.
What this chapter covers
- 01IRAC: Issue → Rule → Application → Conclusion
- 02MIRAT: Material facts → Issue(s) → Rule(s) → Argument/Application → Tentative conclusion
- 03Choosing between them: IRAC saves words when facts need not be restated; MIRAT sets the facts out
- 04Writing the Issue as a precise question of law, not a topic label
- 05Stating the Rule from the correct authority (case or statute) before applying it
- 06Application: arguing the law against the facts, addressing both sides, not just asserting a result
- 07Tentative conclusions: hedging appropriately where the answer is genuinely arguable
- 08Constructing and evaluating legal arguments — the dialectic, plain-English communication
MIRAT on a short criminal-assault scenario
- +1Material facts. Fred deliberately swung a prosthetic leg to make contact with Billy; Billy did not consent and did not see it coming; Billy suffered a bruise. (MIRAT sets the facts out because they drive the analysis.)
- +1Issue. Did Fred commit a common-law assault (in the battery sense) on Billy?
- +1Rule. State the Fagan elements: (1) a voluntary act; (2) force applied directly or indirectly to the victim; (3) intention or recklessness as to that application of force; (4) absence of consent.
- +2Argument — apply each element. (1) Swinging the leg was a voluntary act. (2) Force was applied, at least indirectly, through the prosthetic — an object under Fred's control counts. (3) Fred acted deliberately to make contact, so intention is satisfied (recklessness would also suffice); that it was 'a joke' goes to motive, not intention. (4) Billy did not consent, and there is no basis for implied consent to being struck.
- +1Tentative conclusion. All four elements appear satisfied, so Fred very probably committed assault; the 'joke' does not negate the intentional application of unconsented force. Flag that a court would want to confirm the absence of any consent or horseplay context.
Key terms
- IRAC
- A four-step problem-solving structure: Issue, Rule, Application, Conclusion. It keeps an answer disciplined and lets a marker see your reasoning; it saves words by not restating facts, so it suits tight limits.
- MIRAT
- A fuller structure — Material facts, Issue, Rule, Argument, Tentative conclusion. Used when the facts must be set out and the analysis is contested; it front-loads the material facts before the legal analysis.
- Issue (in IRAC)
- The precise question of law the problem raises, phrased as a question rather than a topic. A sharp issue statement frames the whole answer and is directly rewarded by the Written Assessment's issue-identification criterion.
- Application (in IRAC)
- The step that argues the rule against the facts — the heart of the answer. Strong application weighs both sides and reaches a reasoned position rather than asserting a conclusion.
- Tentative conclusion
- A conclusion expressed with appropriate caution where the answer is genuinely arguable ('a court would probably find …'). It reflects that problem questions often have no single certain answer.
- Legal argument (the dialectic)
- Reasoned argument from authority and principle, addressing counter-arguments, rather than assertion or emotional appeal. Constructing and evaluating such arguments is the core skill the unit assesses.
Legal Problem-Solving: IRAC & MIRAT FAQ
When should I use IRAC and when should I use MIRAT?
Use IRAC when the facts are given and need not be restated — it saves words, which matters under the 3,000-word Written Assessment limit. Use MIRAT when you must set the material facts out first because they drive a contested analysis. Many strong answers toggle between them across a multi-part problem, using IRAC for tight sub-issues and MIRAT where facts are pivotal.
What is the most common mistake in IRAC answers?
Reciting the rule and then asserting a conclusion without doing the Application step. The marks live in arguing the law against the facts — applying each element, weighing both sides, and dealing with the obvious counter-argument. A bare 'the rule is X, therefore Fred is liable' throws away the analysis-and-argument marks, which are the largest slice of the rubric.
How do I write a good Issue statement?
Phrase it as a precise question of law, not a topic label. 'Whether Fred applied unlawful force to Billy without consent' is an issue; 'assault' is just a heading. A sharp issue tells the marker exactly what you are about to resolve and directly earns the issue-identification marks in the Written Assessment.
Can Sia help me practise IRAC and MIRAT?
Yes. Give Sia a fact scenario and ask it to walk the IRAC or MIRAT skeleton with you, or to critique a structure you have drafted, one step at a time. It teaches the method and checks that you have applied the rule to the facts; it does not write your graded assessment, and Monash academic-integrity rules apply.
Exam move
IRAC and MIRAT are muscle memory, so build them by writing, not reading. Take every tutorial problem and draft a visible skeleton — label the Issue, Rule, Application and Conclusion (or the MIRAT equivalents) as headings — so you can see whether each part is actually doing its job. Spend most of your effort on the Application step, because arguing the rule against the facts is where the largest block of Written Assessment marks sits (analysis and argument, 40%). Learn to choose the method by word budget: IRAC when facts are given, MIRAT when they must be laid out. Always finish with a tentative conclusion that commits to a position while acknowledging the genuine uncertainty. Ask Sia to set you fresh scenarios and to mark whether you argued each element or merely asserted a result.
