1. Dangerous Premises – Occupiers' Liability
1.1 Occupiers' Liability to Visitors, Trespassers, and Public Authorities
Occupiers' liability law governs the duty of care owed by those who control premises to people who enter them. The duty varies based on the status of the entrant (e.g., invitee, licensee, or trespasser) and is shaped by statutory frameworks like the Occupiers' Liability Acts in the UK and Australia. A key principle is that liability for a dangerous condition on property is typically predicated upon ownership, occupancy, control, or special use of the premises.
Key Factors in Determining Liability
- Control: A party must have control over the premises to be liable. An out-of-possession landlord is generally not liable unless contractually obligated to repair or has a right to re-enter and make repairs, and the defect is a significant structural one violating a statutory safety provision.
- Foreseeability: The risk of injury must have been reasonably foreseeable. In Willis v Orange City Council [2025] NSWDC 208, the court found the risk from a concealed hole in a grass verge was foreseeable and not insignificant.
- Statutory Defences: Public authorities often have specific statutory defences. In Willis, the Council's defence under s 45 of the Civil Liability Act 2002 (NSW) failed because the court found the Council had "actual knowledge" of the hazard, as its own employees had removed the sign that filled the hole.
1.2 Case Study: Willis v Orange City Council [2025] NSWDC 208
In this Australian case, the plaintiff, Mr. Willis, tripped on a hidden hole in a grass verge in Orange, NSW, causing a serious right shoulder injury. The hole was left by a removed parking sign. The court found the Orange City Council negligent, rejecting its argument that it lacked actual knowledge of the hazard. The court determined that Council employees had removed the sign and conducted works at the site, constituting actual knowledge of the risk.
Case Breakdown
- Plaintiff: Peter Willis (age 76).
- Incident: Fell into a hole concealed by grass on a public verge.
- Defence: Orange City Council pleaded statutory defences under s 42, 43A, and 45 of the Civil Liability Act 2002 (NSW).
- Outcome: The s 42 defence was abandoned. The court found s 43A did not apply as the omission was not unreasonable. The court rejected the s 45 non-feasance defence, ruling that the Council's prior work at the site gave it "actual knowledge." Damages of $133,751.12 plus costs were awarded to the plaintiff.
2. Professional Negligence – Medical, Legal, and Accounting Standards
2.1 The Bolam/Bolitho Test
The standard for professional negligence in medical cases is heavily influenced by the Bolam test, which states that a doctor is not negligent if they act in accordance with a practice accepted as proper by a responsible body of medical opinion. This was later refined by the Bolitho case, which added a crucial caveat: the court is not bound to accept that opinion if it is not logical or capable of withstanding rational analysis.
Key Principles
- Bolam Test: A professional is not negligent if they act in accordance with a practice accepted as proper by a responsible body of peers. This is often called the "professional practice" standard.
- Bolitho Test: The court must be satisfied that the body of opinion relied upon has a logical basis. If the opinion is not logical or defensible, the court can reject it, even if it is supported by experts.
- Application: The Bolitho test gives courts a supervisory role to ensure medical standards are not based on irrational or illogical practices, preventing the Bolam test from becoming a complete shield against liability.
2.2 Tabet v Gett (2010) 240 CLR 537
This High Court of Australia case addressed the issue of "loss of a chance" in medical negligence. A six-year-old girl suffered irreversible brain damage due to a delayed diagnosis of a brain tumor. Her parents argued that she lost the chance of a better outcome because a CT scan was not performed earlier. The High Court rejected the claim, holding that Australian tort law requires proof on the balance of probabilities (more likely than not) that the negligence caused the injury.
Key Takeaways
- Issue: Whether a plaintiff can recover damages for a "lost chance" of a better medical outcome when the chance of success is less than 50%.
- Decision: The High Court held that damages cannot be recovered for a lost chance unless it is proven that the negligence was a necessary condition of the harm occurring. The court required a 50%+ chance of a better outcome to establish causation.
- Significance: This case reaffirmed the "all or nothing" approach to causation in medical negligence in Australia, emphasizing that the plaintiff must prove the negligence caused the injury, not just that it increased the risk.

3. Employers' Liability – Safe Systems, Vicarious Liability, and Statutory Duties
3.1 Employers' Liability for Safe Systems of Work
Employers owe a non-delegable duty of care to provide a safe system of work, safe plant and equipment, competent staff, and proper supervision. This duty, established in cases like English v Wilsons & Clyde Co (1938), cannot be delegated to another employee or contractor, making the employer vicariously liable for any failure in this regard. However, employers can successfully defend claims if they can prove a safe system was in place, the employee was trained, and appropriate equipment was available.
Employer's Core Duties
- Safe System of Work: The employer must design and maintain a system of work that eliminates or minimizes risks to health and safety.
- Non-Delegable Duty: This duty rests squarely on the employer and cannot be outsourced. The employer remains responsible even if the day-to-day management is delegated.
- Limits to Liability: In Ammah v Keuhne+Nagel Logistics Ltd (2009), the court found an employer was not liable when an employee used an unsafe method (standing on a box) despite safe alternatives (steps, forklift) being available and training provided.
4. Product Liability – From Donoghue v Stevenson to Modern Consumer Protection
4.1 The Foundation: Donoghue v Stevenson (1932)
The landmark case of Donoghue v Stevenson established the modern law of negligence and product liability. Mrs. Donoghue fell ill after drinking ginger beer that contained a decomposed snail. The manufacturer, Mr. Stevenson, was found liable, as the House of Lords ruled that a manufacturer owes a duty of care to the ultimate consumer to ensure the product is free from defects that could cause injury, laying the foundation for consumer protection laws globally.
The Neighbour Principle
- Duty of Care: A manufacturer owes a duty of care to the ultimate consumer to take reasonable care in the preparation and putting up of products.
- No Privity Required: The duty exists even when there is no contract between the manufacturer and the consumer (no privity of contract).
- Legacy: This case established the "neighbour principle," which has become the cornerstone of negligence law in common law jurisdictions around the world.
5. Highways & Transport – Liability of Highway Authorities and Road Users
5.1 Liability of Highway Authorities
Highway authorities have a duty to maintain roads in a safe condition for users. The distinction between misfeasance (negligent positive act) and nonfeasance (failure to act) is critical. Authorities are generally not liable for nonfeasance (failure to repair) unless they have special knowledge. However, they can be liable for misfeasance, such as creating a new danger or carrying out repairs negligently.
Key Concepts
- Misfeasance: A highway authority is liable if it creates a new or additional danger through its actions (e.g., digging a hole and failing to erect a barrier).
- Nonfeasance: Traditionally, authorities were not liable for a mere failure to repair a road, but this is subject to statutory exceptions and actual knowledge of a specific hazard.
- "Trap" Principle: An authority can be liable if its actions create a "trap" for road users who have become accustomed to a particular safety feature (e.g., traffic markings) that is then removed without warning.
6. Vicarious Liability – The "Close Connection" Test and Liability for Independent Contractors
6.1 The "Close Connection" Test
Vicarious liability holds an employer liable for the torts committed by an employee in the course of employment. The "close connection" test, established in cases like Lister v Hesley Hall Ltd, asks whether the wrongful act was so closely connected with acts the employee was authorized to do that it can fairly be regarded as done in the course of employment. This test can extend to quasi-employees, but generally not to true independent contractors.
Elements of Vicarious Liability
- Employment Relationship: The tortfeasor must be an employee or in a relationship "akin to employment." This is determined by factors like control, integration into the business, and who provides the equipment.
- Course of Employment: The wrongful act must be closely connected to the authorized duties. In Burger v Risk Solutions & Wetherspoon [2026] EWCA Civ 804, the court found Wetherspoons was not vicariously liable for an assault by a security guard because the guard was an employee of an independent contractor.
- Independent Contractors: Generally, no vicarious liability for true independent contractors, but there are exceptions for "non-delegable duties" (e.g., employer's duty for a safe system of work) or for ultra-hazardous activities.
FAQ
What is the difference between the Bolam and Bolitho tests?
The Bolam test states that a doctor is not negligent if they act in line with a responsible body of medical opinion. The Bolitho test is a qualification to this, stating that the court is not bound to accept that opinion if it finds it to be illogical or unreasonable. In essence, Bolam provides the starting point, and Bolitho gives the court the final say on whether the opinion is defensible.
When is an employer liable for the actions of an independent contractor?
Generally, an employer is not liable for the torts of an independent contractor. However, liability can arise if the employer owes a non-delegable duty, such as the duty to provide a safe system of work. Liability may also arise for inherently dangerous activities or where the employer is negligent in selecting the contractor.
