Legal Reasoning and Analytical Skills
This domain tests how well a candidate reads facts, isolates the legal issue, applies authority, interprets statutes and evaluates arguments.
Case analysis
Use IRAC: Issue, Rule, Application, Conclusion. Separate the ratio decidendi - the principle necessary to the decision, which binds lower courts - from obiter dicta, which are persuasive only. Distinguish a precedent on material facts rather than on surface similarity. A decision given per incuriam, ignoring a binding statute or judgment, loses authority.
Statutory interpretation
- Literal rule: give words their ordinary meaning.
- Golden rule: modify the literal meaning to avoid absurdity or repugnancy.
- Mischief rule (Heydon's Case): identify the defect the statute was passed to remedy.
- Purposive approach: advance the statute's object, consistent with the text.
- Maxims: ejusdem generis, expressio unius est exclusio alterius, noscitur a sociis, and the presumption of constitutionality.
Argument and logic
Legal argument is usually deductive: major premise (rule), minor premise (facts), conclusion. Test validity separately from truth. Watch for fallacies such as affirming the consequent, false dilemma, straw man, ad hominem and appeal to authority. Burdens of proof and standards of proof must be identified before evaluating evidence.
Worked example
A statute prohibits "vehicles" in a public park, and the question is whether a bicycle is covered. Literally, a bicycle is a vehicle. But the mischief may be noise, fumes and danger to pedestrians, which a bicycle does not create. The purposive reading excludes it, while a plain-text court might include it. The strongest answer states the competing readings, identifies the legislative purpose, and applies the interpretation that best fits text and object.
Traps
Treating obiter as binding; applying the literal rule where it defeats an evident purpose; arguing facts without identifying the legal issue; confusing the burden of proof with the standard of proof.
