Negligence Flashcards
What is the Tort of Negligence?
A failure to exercise Reasonable Care and Skill in performing a specific Duty, consequently causing harm to another Party.
What are the Elements of the Tort of Negligence?
- Duty of Care: The Defendant owed the Claimant a Duty of Care.
- Breach: The Defendant violated the Duty of Care.
- Loss: The Claimant suffered a legally-recognised Loss.
- Casuation: The Claimant’s Loss was caused by the Defendant’s Breach.
- Remoteness: The Claimant’s Loss was a reasonable foreseeable consequence of the Defendant’s Breach.
How is the Existence of a Duty of Care determined?
According to what the Parties’ conduct would reasonably suggest, given matters of fact, fairness, and public policy.
What are the Three Tests for Determining the Existence of a Duty of Care?
- The Threefold Test.
- The Incremental Test.
- The Assumption of Responsibility Test.
What is the Elements of the Threefold Test?
- Forseeability: The Claimant’s loss was a reasonably foreseeable consequence of the Defendant’s conduct.
- Proximity: The Claimant-Defendant relationship was one of sufficient Proximity.
- Public Policy: It is fair, just, and reasonable to impose a duty of care between the Parties.
Applied Objectively.
The Threefold Test is the starting point for unprecedent Cases.
In determining the Public Policy criterion, the Court will consider its decision’s social, political, and economic ramifications on society. Considerations include:
- Insurance.
- Floodgates.
- Deterrence.
- Crushing liability.
- Defensive practices.
- Maintenance of high standards.
In the Threefold Test, what constitutes Sufficient Proximity?
A measure of control over, and responsibility for, the situation giving rise to the Loss.
In the Threefold Test, when is it Unnecessary to establish the ‘Public Policy’ criterion?
When there is a demonstrable Voluntary Assumption of Responsibility by the Defendant.
What constitutes a Voluntary Assumption of Responsibility?
- A conscious, considered, or deliberate decision by the Defendant;
- To assume a particular duty vis-à-vis the Claimant.
Applied Objectively.
What is the Incremental Test?
An adjunctive test that mandates new duties in Negligence be developed:
- Incrementally; and
- By analogy with established categories.
This is less of a Test, and more of a Rule.
What is the Assumption of Responsibility Test?
A Test of whether:
-
Voluntary Assumption of Responsibility:
- The Defendant Voluntarily Assumed Responsibility for what he said and did vis-à-vis the Claimant; or
- Is treated by the Law as having done so.
- Reliance: The Claimant reasonably relied on the Defendant’s Assumption.
Applied Objectively.
This is most relevant in Cases of Negligent Misstatement or Professional Negligence, specifically as a more precise form of duty analysis, in recognition of the unique nature of such reliance-based relationships.
Can the Defendant’s Omissions give rise to a Duty of Care?
Yes, but only if the Defendant:
- Is subject to a Stautory Duty.
- Is subject to a Contractual Duty.
- Has created a dangerous situation.
- Has a high degree of control over the Claimant.
- Has Voluntarily Assumed Responsibility for the Claimant’s welfare.
Why is a Public Body less likely to Owe a Duty of Care under the Threefold Test?
- Merely having the ability to do something does not compel performance for a Public Body.
- The Courts are reluctant to create new Duties in Novel Cases because of the Public Policy implications.
- Statute-Empowered actions cannot beget liability in Negligence if performed properly, as that would undermine Parliamentary Sovereignty.
How is the Scope of a Duty of Care determined?
By observing the:
- Factual matrix;
- Contractual terms;
- Parties’ relationship; and
- Responsibilites owed by the Parties to one another.
What is the Defendant’s Standard of Care?
- A Reasonable Person in the Defendant’s position and circumstances; unless
- The Defendant possesses, or claims to possess, special expertise; in which case,
- The standard is that of a Responsible Body of Professionals.
This Test is based on the Act, not the Actor.
The minimum threshold for a Responsible Body of Professionals is an acceptable number of experts with sufficiently strong pedigrees. Solid figures are inapplicable.
What is the Defendant’s Standard of Care if they are a Medical Professional acting in an Advisory Capacity?
- Patients must be informed of all Material Risks involving a Tretment and any reasonable alternatives.
- However, Professionals may withhold if:
- Immediate Treatment is necessary; or
- Disclosure would seriously harm the Patient’s health.
A Material Risk is one that:
- A Reasonable Person would find significant; or
- The Patient themselves would find significant, a fact the Professional is aware of.
What are the Main Factors in determining whether a Breach has occured?
- Common Practice.
- Likliehood of Harm.
- Magnitude of Harm.
- Practicality of Precaution.
- Limitations of the State of the Art.
- Social Value of the Defendant’s Conduct.
Whether the Defendant is engaging in Sport is also relevant.
Does acting in accordance with Common Practice constitute Reasonable Care and Skill?
Yes, but only if:
- The Body of Opinion informing the Practice has a defensible position on its cost-benefit.
For the State of the Art Defence to apply, what must the Practitioner have been doing?
Undertake reasonable efforts to remain abreast of new, and especially mainstream, developments in their field.
When will the Facts Speak for Themselves?
Res Ipsa Loquitur.
- The Accident would not normally occur without negligence.
- The Accident was under the Defendant’s control, or someone for whom they are responsible.
- The Accident’s cause is unknown to the Claimant and they have no direct evidence of the Defendant’s failure to exercise Reasonable Care and Skill.
What is Factual Causation?
Whether, But For the Breach:
- The Loss would not have arisen;
- At that time;
- In that way.
On the Balance of Probabilities (> 50%).
If the Breach is a failure to advise on risk, the Claimant must prove they would have acted differently But For the poor counsel.
What are the Alternative Tests of Factual Causation?
Used when the But For Test is highly difficult or impossible to apply.
- Loss of Chance Test.
- Material Contribution Test.
- Material Increase in Risk Test.
In all these Tests, the alleged consequence(s) of the Breach must be proven on the Balance of Probabilities (> 50%).
What is the Loss of Chance Test?
This Test is confined to cases of Pure Economic Loss. In such cases:
- If the Breach cost the Claimant a real and substantial chance at a better outcome;
- Liability for the Lost Opportunity’s value is found.
What is the Material Contribution Test?
This Test is for when multiple cumulative causes drive the Claimant’s Loss. In such cases:
- If the Breach Materially contributes to the Loss, liability for the whole Loss is found.
- Here, ‘Material’ means more than negligble.
What is the Material Increase in Risk Test?
This Test is confined to case of Industrial Disease with scientific uncertainty as to Causation. In such cases:
- If the Claimant’s Loss arises from a single, identifiable, causal Agent; and
- The Breach Materially increased the risk of harm therefrom;
- Liability for the whole Loss is found.
It is irrelevant whether exposure to the Agent was isolated or cumulative.
What constitutes a Foreseeable Loss?
A loss that one reasonably anticipates would arise from the breached duty.
