Precedent and statutory interpretation (SACE Stage 2 Legal Studies)

An extended-response question wants a sustained, evaluative argument with a judgement, not a definition.

Contention. Argue that precedent provides valuable consistency and gradual development but can be rigid and slow.

Strengths. Consistency, predictability and fairness because like cases are treated alike, and the capacity to develop principle, as in the law of negligence.

Weaknesses. Difficulty identifying the binding ratio decidendi, the risk of rigidity under stare decisis, and dependence on the right case reaching a high enough court.

Flexibility. Note that higher courts can overrule and that distinguishing allows adaptation.

Judgement. Conclude that precedent is effective for consistent, incremental law-making but less suited to rapid or broad reform, which parliament handles better.

Markers reward correct terminology, a real example and a reasoned evaluation.

Award one mark for each type correctly outlined.

1. Binding precedent. A precedent that a court must follow because it was set by a higher court in the same hierarchy and the material facts are similar. The lower court has no choice but to apply the legal principle (the ratio decidendi).

2. Persuasive precedent. A precedent a court may consider and choose to follow but is not obliged to, for example a decision of a court in another hierarchy, a lower court, a court of equal standing, or comments made by the way (obiter dicta).

For two marks, give a reason and support it with a case.

Some disputes arise where there is no statute and no existing precedent that covers the situation - a "gap" in the law - so the judge must develop a new principle to resolve the matter justly. This is how the common law grows.

For example, in Donoghue v Stevenson (1932) a woman became ill after drinking ginger beer containing a decomposed snail, but had no contract with the manufacturer. With no existing law to cover her, the court created the modern law of negligence by establishing the "neighbour principle" - that we owe a duty of care to those we can reasonably foresee being harmed by our actions. The new dispute required the judge to make law.

Two marks per method: name it and outline how it works (two needed).

1. Distinguishing. A judge decides that the material facts of the present case are sufficiently different from those of the earlier case, so the binding precedent does not apply. This lets the judge reach a different outcome without overturning the earlier decision.

2. Overruling. A higher court decides that an earlier precedent set by a lower court (or, for the High Court, its own earlier decision) is wrong or out of date and replaces it with a new principle. The old precedent no longer applies.

Other acceptable methods: reversing (a higher court changing the decision in the same case on appeal) or disapproving.

A 4-mark "discuss" needs both sides and a brief judgement.

Arguments that it leads to just outcomes

Precedent provides consistency and fairness - like cases are treated alike - and predictability, so people can know the law and plan accordingly. It allows the law to develop incrementally through real disputes, and flexibility through distinguishing and overruling lets courts adapt.

Arguments against

Following an outdated or unjust precedent can produce unfair results; the law can be hard to find among thousands of cases; only higher courts can change precedent, so lower courts may be bound to apply rules they consider wrong; and change depends on the right case being litigated by someone who can afford it.

Judgement

A balanced answer concludes that precedent generally promotes just outcomes through consistency and gradual development, but can entrench injustice where reform is slow or access to higher courts is limited.

For two marks, identify one method and explain how it guides interpretation.

One way is through Acts Interpretation legislation (such as the Acts Interpretation Act): Parliament passes general rules directing courts on how to read statutes, for example requiring judges to prefer an interpretation that promotes the purpose or object of the Act (the purposive approach) over a strictly literal reading.

Parliament also guides interpretation through definitions and purpose clauses written into an Act, and through material such as the second reading speech and explanatory memoranda, which courts may use as extrinsic aids to work out the meaning Parliament intended.
