Negligence: Duty of Care and Breach

Neighbour principle, established duty categories, salient features and the calculus of negligence

Property, Intellectual Property and Agency

Finders and fixtures, trade marks and copyright, and express, implied and apparent authority

  • Finders: Armory, Parker and the duty to seek the owner
  • Fixtures and fittings when a business is sold
  • Registered trade marks and infringement under s 120
  • Copyright in original works and AI-generated text
  • Passing off and s 18 for unregistered names
  • Express, implied and apparent authority
In the full guide: 3 pages · 2 practice questions · 1 figure

The course starts with where law comes from: the three tiers of government, the separation of powers, the Commonwealth's heads of power and the reception of English law, then legislation, precedent and statutory interpretation. Negligence follows, taught through the ACT's Civil Law (Wrongs) Act 2002 together with the leading cases on duty, breach, causation and defences.

Three weeks of contract law cover formation, consideration, intention, capacity, estoppel, terms, exclusion clauses, vitiating factors, discharge and remedies. The second half applies those foundations to particular business contracts: sale of goods, the Australian Consumer Law, insurance, property, intellectual property and agency. Assessment is built around legal problem solving.

Two short assignments, each worth 10%, asked for one-page answers on negligence and on intention to create legal relations; a 30% research paper analysed implied terms and frustration; and a final exam worth 50% asks students to apply commercial law principles to hypothetical fact scenarios.

Past finals in the course materials mix several topics in one business story, and four areas have appeared in every sitting since 2021: insurance contracts, consumer law, negligence and trade marks.

This guide follows the teaching order, explains each rule with the cases and sections the lectures and marking guides use, and works an original problem in every chapter so you can practise identifying issues, applying the law to facts on both sides and reaching a reasoned conclusion with a remedy.

Worked example · free

Is a café owner a consumer when her espresso grinder fails?

Q [8 marks]. Nadia buys a $2,800 commercial espresso grinder for her café. It jams repeatedly within a month, and the seller says its terms exclude all guarantees. Advise Nadia under the consumer law and the Sale of Goods Act. The eight marks shown are a self-marking aid for revision, not a University allocation.
Sale of Goods Act terms beside ACL guaranteesEach implied term of the Sale of Goods Act on the left has a matching consumer guarantee in the Australian Consumer Law on the right, linked by dashed rungs.SGA: every buyerACL: consumers onlys 17 titless 51 to 53s 18 descriptions 56s 19 quality, fitnessss 54 and 55s 20 samples 57Guarantees: non-excludable
Each Sale of Goods Act term on the left lines up with the matching consumer guarantee on the right, which is why many answers apply both Acts in parallel once the buyer is shown to be a consumer.
  • +2Consumer status: the grinder cost $2,800, under both the $40,000 threshold stated in the course slides and the $100,000 figure the Act has used since 1 July 2021, so Nadia is a consumer under s 3 of the ACL unless she bought it for resupply or to use up in production; she bought it to use, not resell.
  • +2Guarantee breached: a grinder that jams repeatedly within a month is not of acceptable quality under s 54, and the matching SGA condition of merchantable quality under s 19 also applies to the sale.
  • +2Exclusion: s 64 makes the guarantees non-excludable, and SGA implied terms cannot be excluded in the ACT, so the seller's terms do not remove either.
  • +2Remedy: if the failure is major under s 260 she may reject and choose a refund or replacement (s 263); otherwise the seller may remedy it within a reasonable time (ss 259(2), 261).
Nadia is likely a consumer, the guarantee of acceptable quality is breached, the exclusion fails, and her remedy turns on whether the failure is major.
Sia tip — Write the s 3 consumer test before any guarantee, and check the resupply exception against what the buyer actually did with the goods.

FAQ

BUSN7052 FAQ

How is Commercial Law at ANU assessed in Semester 2, 2026?

The class summary lists four tasks: Assignment 1 and Assignment 2 at 10% each, Assignment 3 at 30% and a final exam at 50%. The first two were one-page problem answers on negligence and on intention to create legal relations, the third a research paper of about 1,800 words. Together they total 100%.

What does the final exam look like?

It is an in-person paper with 2 hours of writing time and 15 minutes of reading time. Students discuss how commercial law principles apply to several hypothetical fact scenarios, there are no multiple choice questions, every topic is examinable, and the questions resemble those set in tutorials.

Can I bring notes into the final exam?

The class summary describes the exam as open book with no special equipment, and says ebooks are not permitted. Permitted materials are published with the examination timetable, so check that listing before the day and prepare printed or handwritten notes organised by legal issue.

Which topics come up most in past finals?

Six past papers from Semester 2 2021 to Semester 1 2025 are in the course materials. Insurance contracts, the Australian Consumer Law, negligence and trade marks appear in all six. Contract terms and exclusion clauses appear in four, while copyright, sale of goods implied terms and finders appear in three.

How should I structure a problem question answer?

Use IRAC. Frame each issue as a question, state the rule briefly with a case or section, spend most of your words applying that law to the facts and arguing both sides, then give a conclusion on balance with the remedy. The course notes say conclusions may differ if well supported.

How much detail does negligence need in a mixed question?

Usually less than students give it. Several marking guides ask for a brief walk through duty, breach and causation with key Civil Law (Wrongs) Act sections, and the 2025 guide warns that some students spend too long there when consumer guarantees and implied terms carry the weight.

When does consumer law apply instead of the Sale of Goods Act?

Both can apply together. The Sale of Goods Act covers any sale of goods for a price, whoever buys. The consumer guarantees apply only when the buyer is a consumer under s 3, which excludes goods bought for resupply or to use up in production, so check consumer status first.

Chapter questions

Questions students ask in each BUSN7052 chapter

Why does a business law course start with the Constitution?
Many commercial statutes rest on Commonwealth heads of power: the slides tie the Corporations Act to s 51(xx) and list insurance under s 51(xiv). Knowing which level of government can legislate, and which law wins when two conflict, tells you which statute governs a dispute before you start applying its provisions. Chapter 01 · The Australian Legal System and the Constitution
What is the difference between reversing and overruling a decision?
Reversal happens when a superior court corrects the decision in the same case on appeal, without necessarily changing the law. Overruling happens when a court replaces the legal rule laid down in an earlier case, so later courts follow the new rule. Distinguishing leaves the earlier rule intact but avoids it on different facts. Chapter 02 · Legislation, Precedent and Statutory Interpretation
Which relationships carry a presumed duty of care?
The Week 3 slides list professionals and clients, employers and employees, teachers and students, road users, and occupiers with their invitees, suppliers and consumers, citing Modbury Triangle. Outside those categories, a duty depends on salient features such as the plaintiff's vulnerability, the defendant's control over the risk, and policy considerations. Chapter 03 · Negligence: Duty of Care and Breach
How does s 45 change the old but-for test?
It splits causation into two questions. Section 45(1)(a) asks whether the negligence was a necessary condition of the harm, which works much like but-for. Section 45(1)(b) asks whether it is appropriate for liability to extend to the harm, and s 45(2) lets courts keep applying established common law principles such as the eggshell rule. Chapter 04 · Negligence: Causation, Defences and Economic Loss
Is a product on a supermarket shelf an offer?
No. A display is an invitation to treat. In the Boots case the customer made the offer at the counter, where the pharmacist could accept or refuse, which also let the pharmacist supervise the sale. Most advertisements work the same way unless they promise something specific in return for an act. Chapter 05 · Contract Formation: Agreement and Consideration
Are agreements between family members ever enforceable?
Yes. Ermogenous removed rigid presumptions, so courts examine the whole context: payment, formality, the seriousness of the promise and what each party gave up. In Todd v Nicol a domestic arrangement became binding because one party made a significant sacrifice in reliance, while in Woodward v Johnston a promised business share stayed a family understanding. Chapter 06 · Intention, Capacity and Equitable Estoppel
How do courts decide whether a statement is a term?
They look for the parties' objective intention using factors the slides list: promissory wording, timing relative to the contract, importance to the decision to contract, the maker's special knowledge, and whether a later written contract left it out. Oscar Chess contrasts saying I believe with saying I guarantee. Chapter 07 · Contract Terms and Exclusion Clauses
What makes a misrepresentation fraudulent rather than innocent?
Fraud requires that the maker knew the statement was false, had no belief in its truth, or was reckless about it. An innocent misrepresentation is made with an honest belief on reasonable grounds. The difference matters because fraud supports damages as well as rescission, while innocent misrepresentation at common law supports rescission only. Chapter 08 · Vitiating Factors and Genuine Consent
When can a party terminate for breach?
When the other party breaches a condition, repudiates the contract, or breaches an intermediate term with serious consequences. Breach of a warranty gives damages only, as Bettini v Gye shows: a singer who arrived late for rehearsals but before the concerts breached only a warranty, so the contract continued. Chapter 09 · Discharge, Frustration and Contract Remedies
Does the Sale of Goods Act apply to software?
It depends on the form. Software on a physical disc is goods, but a paid download was held not to be goods in Gammasonics, so the Act did not apply. The Australian Consumer Law is broader, because its definition of goods expressly includes computer software, as Valve Corporation v ACCC confirms. Chapter 10 · Sale of Goods: Implied Terms, Property and Risk
Is a business that buys stock to resell a consumer?
No. Section 3 excludes goods acquired for resupply, whatever their price, and goods acquired to use up or transform in trade or commerce. A past answer guide applied this to a café buying coffee beans: even below the price threshold, beans bought for the business fell outside the guarantees. Chapter 11 · Australian Consumer Law: Guarantees and Misleading Conduct
Why does classification matter so much in insurance questions?
It decides the duty. A consumer insurance contract under s 11AB carries the s 20B duty to avoid misrepresentation; any other contract carries the s 21 duty of disclosure, which reaches matters the insurer never asked about, including changes in circumstances. The 2025 marking guide warned that some students would misclassify a business policy as a consumer contract. Chapter 12 · Insurance Contracts: Disclosure and Claims
Does an employee who finds something at work keep it?
Usually not. A 2021 answer guide applied Wiley v Synan and Byrne v Horne to a cleaner who found a valuable item while clearing rubbish: found in the course of employment, it had to go to the employer, and the event organisers had to try to locate the true owner. Chapter 13 · Property, Intellectual Property and Agency
Study strategy

How to study for the exam

Revise by issue rather than by week. Build one page for each recurring issue: consumer status and guarantees, misleading conduct, negligence elements, insurance disclosure, exclusion clauses, formation, intention and estoppel, trade marks and copyright, finders and agency.

On each page write the test in a few lines, the sections that state it, two cases you can cite by short name, and the trigger facts that tell you the issue is present. Then practise on full scenarios. Past finals use one business story with several questions, so set a timer, list every issue in the first few minutes and only then write.

Compare your issue list with a model route before polishing your prose, because missing an issue costs more than an awkward sentence. Keep negligence short when the question is wider, classify an insurance contract before naming the duty, and finish every answer with a conclusion and a remedy. In the last week, turn your issue pages into a tabbed open-book kit that you can navigate quickly under exam conditions.
