Legal Reasoning
Scope
Legal reasoning tests your ability to apply a given rule to unfamiliar facts, distinguish precedent, interpret statutes and draw valid inferences. It is less about reciting law and more about showing the steps from principle to conclusion.
Core rules
- Ratio decidendi is the binding rule; obiter dicta are persuasive only.
- Statutory interpretation: literal rule, golden rule, mischief rule and purposive approach; presumptions against retrospectivity and against deprivation of liberty.
- Maxims: ejusdem generis, noscitur a sociis, expressio unius est exclusio alterius.
- Analogical reasoning requires a relevant similarity; distinguishing requires a material difference.
- A syllogism is valid only if the major premise, minor premise and conclusion are properly connected.
Worked example
Rule: “No person shall enter the protected park without written permission.” A forest officer enters to extinguish a fire. Literal reading bars him; purposive reading allows necessary official action to protect the park. The better legal answer identifies the purpose, the exception implied by necessity, and the limits of the exception.
Traps
Do not treat every judicial observation as ratio. Do not assume that a moral duty is a legal duty. In principle-fact questions, state the principle, apply it to the facts, and give a conclusion; unsupported intuition loses marks.
