Duty of Care and Negligence: Comprehensive Exam Notes
In this session, the instructor guides students through the core concepts of duty of care within negligence, including key tests, cases, and practical exam strategies. The discussion uses a running example of a small, busy family restaurant to unpack when a defendant owes a duty of care, whether that duty is breached, and how foreseeability, proximity, and policy considerations shape liability. The material covers immediate principles, landmark cases, and how to structure a clear, signposted answer in an exam setting. It also includes practical notes about using AI tools (CypherBot) and Canvas for course materials and assignments.
The Four Elements of Negligence
Negligence in tort law is analyzed through four essential elements. These are typically listed in sequence as:
Duty of care: a legal obligation to avoid acts or omissions that could foreseeably harm others.
Breach: failure to meet the standard of care expected in the circumstances.
Causation: the breach must cause the harm.
Damages/Defenses: actual damage must occur, and the defendant may raise defenses to defeat liability or limit damages.
The four elements form a framework you apply in sequence when evaluating a scenario. If any element is missing, there is no negligence.
Duty of Care: The Caparo Three-Part Test and Foundational Cases
To establish a duty of care in most cases, English law now uses a three-part test derived from Caparo Industries plc v Dickman (1990), building on the earlier Donoghue v Stevenson (1932) neighbor principle. The three parts are:
1) Reasonable foreseeability of harm (foreseeability): Was it reasonably foreseeable that the defendant's conduct (or omission) could injure the claimant? This part was shaped by Donoghue v Stevenson (the neighbor principle) and later refined by Caparo. A key elaboration is Haley v London Electricity Board (1965): in deciding what is reasonably foreseeable, one must have regard to common knowledge.
2) Sufficient proximity of relationship (proximity): Was there a sufficiently close relationship between the defendant and the claimant such that it is fair to impose a duty of care? Proximity is described in Caparo as a convenient shorthand for the relationship that makes it fair and reasonable to impose a duty; Stovin v Wise (1996) emphasizes that proximity is about the relationship between the parties and not a separate standalone concept.
3) Whether it is fair, just and reasonable to impose a duty (policy test): Even if the first two elements are satisfied, judges assess broader policy considerations to avoid opening the “floodgates” of liability. This third element weighs societal costs and benefits of imposing liability in the given class of cases.
If one or both of the first two tests fail, there is no duty of care. If both are satisfied, the third test is typically addressed affirmatively, though in rare policy-driven circumstances it may still defeat liability.
The Caparo framework is a structured, exam-friendly way to approach duty of care: state the three tests, apply them to the facts, and conclude whether a duty exists.
Key cases associated with the duty-of-care framework:
Donoghue v Stevenson (1932): Establishes the neighbor principle guiding foreseeability and proximity.
Caparo Industries plc v Dickman (1990): Sets out the three-part test (foreseeability, proximity, policy).
Haley v London Electricity Board (1965): Foreseeability must take into account common knowledge when assessing what is reasonably foreseeable.
Stovin v Wise (1996): Proximity is a relationship concept; proximity is not a separate, fixed ingredient but a way of describing the relationship.
Michael and Chief Constable of South Wales (2015): Policy considerations regarding whether to impose a duty may evolve over time; the third caparo factor can reflect changing public interest concerns.
A practical note from the lecture: precedents matter. If there is an existing precedent that answers whether a duty of care is owed, you should apply it. The instructor cautions not to rely on precedent shortcuts in exam answers; instead, you should apply the three-part test as if there is no precedent, and only reference precedent where appropriate and clearly.
The Caparo Three-Parts in Practice: Signs, Signposts, and Significance
Reasonable foreseeability of harm: To decide what is reasonably foreseeable, consider common knowledge ( Haley ). In Haley, Lord Reed stated that common knowledge should guide what a reasonable foreseeer would anticipate.
Proximity: The relationship need not be perfect or direct; it is a broad concept that looks at the circumstances and whether a reasonable foreseeer would have anticipated a duty to the claimant given the relationship. The example in Stovin v Wise clarifies that proximity is a convenient shorthand for the relationship that makes it fair to impose a duty.
Fair, just and reasonable: This policy-based assessment weighs the total impact on public interest against individual losses if a duty is found. Courts discuss this aspect when necessary, but for exam purposes you typically conclude “yes” if the first two elements are satisfied.
In applying Caparo in exams, the structure generally follows:
State there is a three-part duty-of-care test (Caparo and Donoghue references).
Analyze the first test (foreseeability) with facts and law, including common-knowledge considerations (Haley).
Analyze the second test (proximity) with the relationship in the facts (Jane as customer, Steve as restaurant owner).
Analyze the third test (policy): usually conclude yes if the first two are satisfied.
Provide a concise conclusion about whether a duty of care exists.
Signposting tips from the lecture:
Use clear transitions from law to facts (e.g., “Applying the reasonable foresight of harm test to the facts: …”).
Name the rule first, then apply it to the facts, and finally state the conclusion (law-fact-law-conclusion). Avoid long blocks of law then long blocks of facts without signposting.
Signpost terms such as “Firstly/Secondly,” “In this case,” “Applying the rule to the facts,” and “Therefore” to guide the reader through your reasoning.
The Steve and Jane Scenario: Applying Duty of Care
The running scenario: Steve owns a small, busy family restaurant. He mops the floor, leaving it wet and slippery. Jane, a customer, slips on the wet floor and sprains her ankle. The class discussion asks whether Jane will succeed against Steve and how to analyze it under the duty-of-care framework.
How to approach the analysis in an exam:
Identify the defendant and plaintiff: Steve (defendant) and Jane (claimant).
Establish duty of care using Caparo three-part test.
Apply the test to the facts step-by-step with signposted paragraphs.
Consider foreseeability of harm: Was it reasonably foreseeable that something like a wet floor could cause a slip? Use common-knowledge support (Haley).
Consider proximity: Is Jane sufficiently closely affected by Steve’s actions (or omissions) given that she is a customer in his restaurant?
Consider the policy (fair, just, and reasonable): Is it appropriate to impose a duty on restaurant owners in these circumstances, or would that impose too wide a liability?
A worked outline (illustrative):
Introduction: There is a three-part duty-of-care test (Caparo, Donoghue). In this case, the key question is whether Steve owed Jane a duty of care.
First leg (foreseeability): State the rule (it is reasonably foreseeable that a wet floor could cause a slip). Apply Haley’s common-knowledge principle and describe how mopping a floor and leaving it wet is a situation commonly understood to create slip risk. Apply to the facts: “Steve was mopping the floor and the floor was wet; it was reasonably foreseeable that a customer such as Jane could slip.”
Signpost to the facts: “In this case, Jane was a customer in Steve’s restaurant; the floor was wet due to mopping.”
Second leg (proximity): Identify the relationship: Steve, as the restaurant owner, owes a duty to customers (Jane) who are in his business premises. State that there is a sufficient proximity between Steve and Jane by virtue of Jane’s presence as a customer in Steve’s restaurant.
Signpost to the facts: “Jane, as a customer, and Steve, as the owner, share a direct relationship in the context of the restaurant.”
Third leg (policy): State that it would be fair, just, and reasonable to impose a duty of care on a restaurant owner in this context to maintain safe premises.
Conclusion: Given foreseeability and proximity, the court would be likely to find a duty of care owed by Steve to Jane (subject to consideration of any defenses or contributory negligence).
Important nuances raised in the discussion:
Jane’s behavior (skipping to the toilet) was debated as potentially contributing to the risk. The lecturer notes you should not “invent facts” and should base your analysis strictly on the facts given in the scenario. If a fact is stated (e.g., Jane was skipping), you may discuss whether that behavior affects foreseeability and proximate relationship but avoid making unsupported assumptions.
Foreseeability can be influenced by common knowledge about ordinary human behavior and the environment (e.g., a busy restaurant with a wet floor is a foreseeable hazard).
The balance of responsibility can be discussed in terms of signs: If Steve had put up a sign warning customers of the wet floor, the outcome could differ depending on whether a sign was visible and understandable to customers.
The concept of “joint and several liability” and “several concurrent liability” was introduced as potential complexities in cases with multiple defendants or claimants.
The Signposting and Exam-Writing Technique: Structure Matters
The lecturer emphasizes a practical, exam-ready writing style:
Present the law first (the duty-of-care test, including the Caparo three parts).
Then move to the facts (apply the law to the Steve and Jane scenario).
Alternate between law and facts paragraph by paragraph: law, fact, law, fact, law, fact.
Use clear signposts to guide the judge through your reasoning: “Firstly, the duty-of-care test requires X; applying it to the facts, Jane was a customer, Steve had a duty to maintain safe premises; therefore, foreseeability is established.”
Do not present blocks of law followed by blocks of facts without explicit connection; instead, tie each application to the specific rule you stated.
Conclude each test after applying it (e.g., “Therefore, it was reasonably foreseeable that Steve’s failure to take care could cause harm to Jane.”) and then proceed to the next test.
The examiner expects you to discuss the case law with proper citations (case names and years). If you reference Caparo and Donoghue v Stevenson, you should typically name the cases and the year in parentheses (for example, Caparo Industries plc v Dickman (1990); Donoghue v Stevenson (1932)). The lecturer notes that exact formatting is flexible, but the year and case name are usually sufficient in exams.
In addition, the lecturer highlights the importance of prioritizing issues. In any given scenario you may find some elements (duty, breach, causation, damage) more central than others. Practice helps you decide where to devote more words to analysis and where a brief statement suffices.
Recognized Duties, Special Duties, and Liability Concepts
Recognized duties: There are certain situations where a duty of care is presumed due to the relationship (e.g., doctor-patient, parent-child, teacher-student, road user to another). These are “recognized duty situations” where the court will typically find a duty without running the full Caparo test.
Special duties: The course will cover specialized scenarios (psychiatric harm, economic loss, public bodies, acts of third parties, omissions) for which different tests or considerations may apply.
Joint and several liability vs. several concurrent liability: In negligence, more than one defendant can be liable; liability can be shared across defendants in various ways depending on the facts and the jurisdiction.
The lecture notes that these are treated in later lessons, but the core duty-of-care question remains the central starting point for negligence analysis.
Practical Exam Strategy and Practice Tips
Use a three-step approach (duty, breach, causation) with a separate discussion of defenses, then conclude. The Caparo framework helps anchor the duty analysis.
In an exam, include a brief paragraph on the role of precedent but proceed as if there is no precedent for the purposes of applying the three tests. This demonstrates your ability to apply the test directly to the facts.
Use the “sword and shield” metaphor for cases: cases act as a sword (establishing duty, breach, causation) and a shield (defenses). Recognize both sides when analyzing a scenario with multiple parties.
Signpost carefully: alternate law and application, and always label which test you are applying. For example: “First, the reasonable foresight of harm test requires…” followed by “Applying this to the facts: …” then “Conclusion: …” Then move to the next test with a similar structure.
Practice with the Steve and Jane scenario repeatedly to become fluent in law-to-facts transitions and to build a cohesive paragraph structure for exam essays.
Precedent and How It Affects Your Answer
Precedent plays a role in how courts decide duty of care, but in exams you should not rely on “precedent-first” reasoning unless explicitly instructed. The decision tree for duty of care includes, first, whether there is existing precedent that dictates a duty; if the answer is yes, apply it. If the answer is no, proceed with the three-part Caparo test.
Caparo and Donoghue v Stevenson serve as the foundational toolkit for duty. Haley v London Electricity Board reinforces the role of common knowledge in foreseeability, while Stovin v Wise emphasizes proximity as a relationship concept rather than a stand-alone factor.
Real-World Relevance and Ethical Implications
The duty-of-care framework balances individual accountability with societal considerations. The policy test (fair, just, and reasonable) allows courts to avoid floodgates that could overwhelm the system with liability claims.
In practice, recognized duties help allocate liability predictably in standard relationships (e.g., doctor-patient). Special duties and public-interest considerations reflect evolving social norms and regulatory needs.
Courts weigh the public interest against individual losses when deciding whether to impose liability; this balancing act helps maintain access to justice while preserving the integrity and efficiency of the legal system.
CypherBot, Canvas, and In-Class AI Tool Integration
The instructor introduces CypherBot (an AI tool) and Canvas as part of the course workflow. Access to CypherBot is coordinated via Canvas announcements, with a class code provided in announcements and an associated passcode to join.
The workflow described:
Ensure you have Canvas access; check announcements for CypherBot instructions.
Complete a demographic survey (short, quick).
Log in to CypherBot and perform three microtasks: ask it three clarification questions about today’s lesson content, definitions, or summaries.
After the microtasks, complete a short consolidation survey.
The CypherBot content is derived from course-uploaded documents rather than live Internet sources to ensure accuracy and alignment with the course materials. The instructor invites students to suggest additional documents for uploading so CypherBot can answer more accurately using primary sources.
Class logistics mentioned include: class ID 652 (Law652), and a passcode to join CypherBot (details provided in announcements). The instructor notes the goal of using CypherBot to reinforce understanding and summarize material (e.g., proximity) and to practice writing three-part duty-of-care paragraphs.
If you have access issues, the instructor encourages trying later (and using Canvas to coordinate questions and feedback). The class is also introduced to a summary task with CypherBot: summarize proximity in a concise line or two, based on today’s content.
Summary of Core Points to Remember (Cheat-Sheet)
Negligence requires four elements: Duty of care, Breach, Causation, Damages. Formally:
Duty of care is assessed by the Caparo three-part test:
1) Reasonable foreseeability of harm (Donoghue v Stevenson; Haley).
2) Sufficient proximity of relationship (Stovin v Wise).
3) Whether it is fair, just, and reasonable to impose a duty (policy considerations).Foundational cases to know: Donoghue v Stevenson (1932), Caparo Industries v Dickman (1990), Haley v London Electricity Board (1965), Stovin v Wise (1996), Michael v Chief Constable of South Wales (2015).
Special/different duties exist for recognized relationships (doctor-patient, parent-child, teacher-student) and for special situations (psychiatric harm, economic loss, public bodies, third-party acts).
In applying the duty test, use clear signposts and structure: law → fact → law → fact → conclusion. Signpost with phrases like "Firstly, the reasonable foreseeability test…" and "Applying this to the facts…".
Remember: if there is no damages or no causation, there is no tort, even if a duty exists. If the claimant did not suffer harm, liability may not lie.
In the Steve-and-Jane scenario, discuss whether Steve owed Jane a duty by examining foreseeability (wet floor hazard), proximity (customer relationship), and policy (avoid floodgates). Consider Jane’s behavior and whether signs or precautions would alter liability.
CypherBot and Canvas workflow can help reinforce understanding and provide quick practice in formulating three-part duty paragraphs.
If you want, I can convert this into a more compact outline focused specifically on your upcoming exam format (e.g., a two-page sheet with a step-by-step paragraph template and a checklist of cases to cite in each section). Also, tell me if you prefer the notes to emphasize more on the Steve-Jane example, or on the cases and the three-part test, or on signposting and exam-writing technique.
