Case Analysis – Donoghue v Stevenson Introductory Lecture

Two principal lines of cases the course will track:
- Negligence – tracing the legacy of Donoghue v Stevenson.
- Privacy – from Hosking & beyond.
Over-arching jurisprudential themes to observe in both lines:
- Symmetry – how coherent doctrine develops within the common-law method.
- Judicial Role – the boundary between incremental development and judicial over-reach.
“Some Key Concepts” (flagged for continuous revision) will anchor each class.

Administrative/Advice segment:
- Key attributes & survival tips for first-year law.
“Warm-up” review of foundational common-law concepts.
Commence close reading of Donoghue v Stevenson $[1932] AC 562$ .

Repeated emphasis on the need to read, read, and read primary sources.
A slide showing the lecturer “Looking for my motivation to study” signals the common struggle and normalises seeking constructive strategies.

Curiosity – locate a personal “hook” in each topic.
Embrace Uncertainty – legal problems are seldom tidy.
Resilience & Perseverance – sustained effort through dense material.
Courage – willingness to state a view even if tentative.
Collegiality – cultivate peer learning; mirrors the profession’s collaborative ethic.
NZLSA Survey underscores that students who intentionally practise these traits exhibit higher academic satisfaction & lower burnout.

Common Law – judge-made law evolving through precedent rather than statute.
Civil vs Criminal Proceedings
- Civil → Rights/wrongs between private parties; remedy usually $\text{damages}$ or equitable relief.
- Criminal → State prosecutes conduct deemed an offence; remedy includes punishment.
Party Labels
- Plaintiff v Defendant – trial court (civil).
- Appellant v Respondent – on appeal.
Ratio Decidendi – the binding legal principle necessary to decide the case.
Obiter Dictum – persuasive but non-binding judicial observations.
Stare Decisis – doctrine obliging courts to follow binding precedent.
Cause of Action – legally recognisable claim that, if proven, entitles plaintiff to a remedy.

Setting: Paisley, Scotland. May Donoghue visits a café with friend Rita Random; Rita buys May a ginger-beer in an opaque bottle.
Alleged mishap: Decomposed snail in the bottle; May claims shock & gastro-enteritis.
May’s Goals Before the Court
- Obtain damages (monetary compensation).
- Establish the existence of a duty of care owed by the manufacturer.
Procedural Nature: Civil – branch of tort law (specifically negligence).

Objective: Restore plaintiff to pre-tort position.
Classic formula (Livingstone v Rawyards Coal Co $(1880) 5 App Cas 25$ , Lord Blackburn):
- $Compensation = \text{Sum that places plaintiff in the same position as if the wrong never occurred}$
Key term “restitution” refers not to return of property but holistic monetary equivalent – physical, emotional, economic.

Manufacturer/seller liable in tort only when:
1. Product inherently dangerous (e.g.
  explosives).
2. Fraud in marketing (knowingly false representations).
3. Non-disclosure of a known danger to purchaser.
No general duty to the ultimate consumer absent these narrow categories.

“Does a manufacturer of a drink in an opaque bottle owe a duty of care to the ultimate consumer to ensure the product is free from defect?”
- If Yes → Recognises broader neighbour principle & transforms product-liability law.
- If No → Maintains traditional privity-based limitations.

Symmetry: Observe how Donoghue shifts doctrine yet remains anchored in common-law logic.
Judicial Role: Study Lords’ reasoning as case study in incremental development versus legislative change.
Forward Link: Subsequent lectures will trace how Hosking (privacy) applies a similar analytical framework.

Consumer Protection – moral imperative for safety where consumers cannot inspect goods.
Economic Impact – how expanded duty reshapes manufacturing practices & insurance markets.
Philosophical Note – Embodies shift to a relational view of responsibility (“neighbour principle”).
