Case Law & Precedent II: Reading & Applying Cases
Topic 3 turns precedent into practice: how to read and brief a case across its five elements (facts, issue, decision, reasoning/ratio, order) and how a later court can follow, affirm, overrule, reverse or distinguish an earlier decision. This is the exact technique behind the case note in the 30% Research Assignment, and applying a precedent to fresh facts is a recurring move in the 40% Written Assessment.
What this chapter covers
- 01Briefing a case: the five (to six) elements — material facts, procedural history, legal issue(s), ruling/ratio, reasoning (incl. obiter), order
- 02How a later court treats a precedent: follow, affirm, overrule, reverse, distinguish, avoid
- 03Distinguishing: finding the earlier case materially different on the facts so it does not bind (the precedent still stands)
- 04Overruling vs reversing: a superior court replacing a rule vs an appeal court changing the outcome of the same case
- 05'Avoiding' a precedent — grounds a sufficiently superior court may rely on (statement too wide, obiter not ratio, changed social conditions)
- 06Applying a precedent to new facts: assessing factual similarity and whether the rule transfers
- 07Reading a case citation and the structure of a reported judgment
- 08Worked case-reading exemplars (invitation-to-treat / limitation-period style cases) — see the practice set
Brief a case, then decide how a later court treats it
- +1Material facts (of the leading case). Goods were displayed on an open shelf; a customer selected them; a human cashier completed the sale at the till. These are the facts the rule rests on.
- +1Issue and ratio. Issue: at what moment is the contract formed in a self-service sale? Ratio: a shelf display is an invitation to treat, not an offer — the customer makes the offer, which the retailer accepts at the till.
- +1Order / significance. The decision fixed the point of contract formation in self-service retail; its ratio is the rule a later court must consider.
- +1Apply to the new facts — are they materially the same? The vending machine dispenses goods automatically on payment, with NO human acceptance step. The leading case's rule depends on a human accepting the offer at the till; that material fact is absent here.
- +1Conclusion — distinguish. Because the machine's automatic operation is materially different from a staffed till, the later court can distinguish the leading case (the display/machine is better analysed as the offer, accepted by inserting payment). The precedent is not overruled — it stays good law for staffed sales; it simply does not govern these facts.
Key terms
- Case brief
- A structured summary of a decision across its core elements — material facts, procedural history, legal issue(s), ruling/ratio, reasoning and order — used to extract the rule and to build a case note.
- Procedural history
- Where and how a case was heard before reaching the present court, and why it came up on appeal. It explains the posture of the decision and which court's ruling is being reviewed.
- Distinguishing
- A later court finding the earlier case materially different on its facts, so the earlier ratio does not bind. The precedent itself remains valid — it simply does not apply to the new facts.
- Overruling
- A superior court declaring an earlier court's rule wrong, so it ceases to be binding and is replaced. Distinct from distinguishing (which leaves the precedent standing) and from reversing (which changes the outcome of the same case on appeal).
- Affirming
- A higher court agreeing with, and thereby confirming and strengthening, a precedent that was not strictly binding on it. Contrast overruling, where the higher court disagrees.
- Avoiding a precedent
- A sufficiently superior court declining to follow a precedent on recognised grounds — the statement of law was too wide, it was obiter not ratio, it is distinguishable, social conditions have changed, or the precedent is unsatisfactory.
Case Law & Precedent II: Reading & Applying Cases FAQ
What are the elements of a case brief?
Material facts, procedural history, the legal issue(s), the ruling/ratio, the reasoning (including any obiter), and the order the court made. Some briefs add the parties' submissions. The same structure is the backbone of the case note in the 30% Research Assignment, so briefing cleanly now pays off directly at assessment.
What is the difference between distinguishing and overruling a case?
Distinguishing keeps the precedent alive — a later court says the facts are materially different, so the rule does not apply here. Overruling kills the rule — a superior court says the earlier rule was wrong and replaces it. Only a superior court can overrule; any court can try to distinguish. Confusing the two is a common and costly slip in problem answers.
How do I apply a precedent to a new set of facts?
State the precedent's ratio, then compare its material facts with your facts. If they are relevantly similar and the precedent is binding, you follow it; if there is a material difference, you can distinguish it and argue a different result. The quality of the comparison — not just the label — is what earns marks.
Can Sia help me brief and apply cases?
Yes. Ask Sia to walk a case brief with you element by element, then give it new facts and have it test whether the precedent binds, can be distinguished, or is merely persuasive. It teaches the technique and checks your reasoning step by step; it will not complete your graded case note for you.
Exam move
Brief every case to the same five- or six-element template until the shape is automatic, and store your briefs so you can reuse them for the case note in the Research Assignment. Then drill the 'treatment' vocabulary — follow, affirm, overrule, reverse, distinguish — by taking a case you have briefed and inventing small fact-changes that would let a later court distinguish it. The high-value exam skill is applying a precedent to fresh facts, so practise writing the comparison out: 'the material facts here differ from [case] because …, therefore …'. Keep 'overrule' reserved for superior courts only. Ask Sia to generate transfer problems — a briefed case plus new facts — and to check whether you have correctly followed or distinguished it.
