Law of Tort Explained: Negligence & Fault (Part 1)

Causation connects the breach to the damage in negligence. There are two types: factual causation (but for test) and legal causation (remoteness test). Factual causation asks if the harm would not have occurred but for the defendant's actions. Legal causation asks if the type of harm was reasonably foreseeable. The remoteness test cuts off compensation when damage is too far from the original act. Once the type of harm is foreseeable, it doesn't matter if it occurred in an unforeseeable way, to an unforeseeable extent, or as a result of a pre-existing condition.

Proving damage requires establishing both factual causation (but-for test from Barnett v Chelsea Hospital) and legal causation/remoteness. Factual causation faces challenges with multiple concurrent causes (Wilsher v Essex), where claimants must prove more than 50% likelihood of defendant's breach being the cause. Legal causation requires damage to be of a foreseeable kind (Wagon Mound), making defendants liable for full extent regardless of whether extent was foreseeable. Additional principles include novus actus interveniens (Smith v Littlewoods) and the thin skull rule (Smith v Leech Brain), requiring defendants to accept victims as found.

Causation establishes the link between breach of duty and damage. The 'but for' test asks whether harm would have occurred but for the defendant's actions. In Barnett v Chelsea Hospital (1969), the hospital was not liable because the patient would have died anyway without treatment. The material contribution to risk principle allows recovery when multiple causes exist and it's impossible to prove which caused the harm (Fairchild v Glenhaven Funeral Services 2003). Legal causation examines whether an intervening act breaks the chain—foreseeable intervening acts may not absolve liability. Remoteness limits recoverable damages to foreseeable consequences; Wagon Mound No 1 (1961) held defendants not liable for fire damage from oil spill because it was not foreseeable. The eggshell skull rule holds defendants fully liable for all harm caused, even if more severe than expected due to pre-existing conditions.

This section explains the two tests for causation in negligence. Factual causation uses the 'but for' test: but for the defendant's act, would the harm have occurred? In Barnet v Chelsea and Kensington Hospital, a doctor was not liable for a patient's death because no medical treatment would have saved him. Legal causation asks whether the damage was reasonably foreseeable and not too remote. In Wagon Mound, a ship owner was not liable for fire damage because no reasonable person would foresee oil on water catching fire from welding sparks. The thin skull rule means defendants take victims as they find them, even if they have unusual vulnerabilities. Intervening acts can break the chain of causation, as demonstrated in Jenny v Barbara where a mechanic was not liable for a fire started by a customer's intervening act.

In negligence law, causation connects the wrongful act to the resulting damage through two components: factual causation (using the 'but-for' test to determine if the damage would have occurred without the act, with solutions for concurrent causes using the 'sufficient cause' test and for evidentiary issues using the doctrine of evidence destruction) and legal causation (using three subtests—foreseeability, risk, and common sense—to limit liability to foreseeable and relevant consequences).

Three primary defenses to negligence claims include: (1) Voluntary assumption of risk - a subjective test requiring the plaintiff to appreciate and understand the specific risk that actually caused the injury; (2) Proportionate liability - limits concurrent wrongdoers' liability to their proportion of responsibility for the loss; (3) Illegality - generally does not bar negligence claims unless the plaintiff was injured during commission of a crime, though courts may still find liability if negligence standards were breached despite unlawful conduct.

In tort law, two key defences to negligence are volenti non fit injuria (consent) and contributory negligence. Volenti non fit injuria is a full defence where the defendant proves the claimant voluntarily accepted the risk with knowledge of precise dangers and free choice, but it cannot be used in road traffic accidents due to the Road Traffic Act 1988. Contributory negligence is a partial defence reducing damages proportionally (1-99%) when the claimant's unreasonable actions contributed to their injuries, assessed against what a reasonable person would have done given the defendant's negligence.

In negligence law, three primary defenses can reduce or eliminate a plaintiff's recovery: (1) Contributory negligence traditionally bars a negligent plaintiff from recovering any damages if they contributed to their own injury, though most states have replaced this with comparative negligence; (2) Comparative negligence apportions recovery based on fault percentages, with pure comparative negligence allowing recovery even if the plaintiff is primarily at fault, while partial comparative negligence bars recovery only when the plaintiff's fault equals or exceeds 50%; (3) Assumption of risk bars recovery when a plaintiff voluntarily enters a dangerous situation with full knowledge of the risks, requiring either expressed or implied consent where the plaintiff had a genuine choice to participate.

Defendants can raise several defenses: (1) Contributory Negligence - if the plaintiff was also negligent, they cannot recover damages; (2) Voluntary Assumption of Risk - if the plaintiff knowingly exposed themselves to danger; (3) Inevitable Accident - if the harm occurred despite all reasonable care; (4) Act of God - if natural forces beyond human control caused the harm. These defenses can reduce or eliminate liability depending on the circumstances.

The voluntary assumption of risk defense (volenti non fit injuria) bars claims when plaintiffs knowingly accept risks. Four conditions must be met: (1) full awareness of the risk; (2) understanding its nature and extent; (3) voluntary acceptance without compulsion; (4) acceptance of the whole risk. However, intoxicated persons cannot claim this defense. The Civil Liability Act simplified this by assuming awareness for obvious risks and inherent risks, shifting the burden to defendants to prove plaintiffs were not aware.

Vicarious liability is employer liability for employee torts in course of employment. Elements: (1) Employer-employee relationship; (2) Tort in course of employment. Employer-employee relationship tests: (1) Control test - who controls is employer; (2) Business integration test - contract of service where work forms integral part of business; (3) Economic reality test - who bears benefits and losses. Course of employment: authorized act, slight detour, criminal act closely related to work, negligent act, express prohibition. Product liability is manufacturer liability for defective products causing damage to ultimate consumer. Elements: (1) Defendant is manufacturer; (2) Manufactured product; (3) Put up for sale; (4) Plaintiff is ultimate consumer; (5) No intermediate examination; (6) Breach of duty; (7) Damage. Caveat emptor applies where product can be examined before consumption.

Vicarious liability is when one person is held liable for the wrongful acts of another. There are three main categories: (1) Principal is liable for agent's acts - if an employee or agent causes harm while performing their duties, the principal is liable; (2) All partners are liable for any partner's acts - in partnership, all partners are jointly liable for any partner's wrongful acts; (3) Master is liable for servant's acts - employers are liable for employees' wrongful acts committed in the course of employment.

This video provides a comprehensive overview of tort liability concepts. Strict liability applies when dangerous objects escape from one's land causing harm, with exceptions for voluntary assumption of risk. Enterprise liability covers inherently dangerous business activities. Vicarious liability follows the 'respondeat superior' principle, holding employers liable for employee actions within the scope of employment, including law firm partners. However, the state is not liable for police officers performing sovereign functions like maintaining law and order. The key distinction lies in whether the person is acting within their employment scope or performing sovereign governmental functions.

Vicarious liability is a legal principle where one person is held liable for the wrongful acts of another, arising only when there is a specific relationship between them and the wrongful act is connected to that relationship. The three primary relationships where vicarious liability applies are: (1) Principal and Agent, where the principal is liable for the agent's acts within the scope of authority; (2) Partners in a partnership firm, where all partners are jointly liable for any partner's wrongful acts; and (3) Master and Servant, where the master is liable for the servant's acts committed during the course of employment. For master-servant liability, two conditions must be met: the wrongful act must be committed by the servant under the master's direction and control, and it must occur during the course of employment. Independent contractors are generally not subject to vicarious liability unless the master authorized the illegal act or strict liability applies.

Compensatory damages include economic damages (medical costs, lost wages) and non-economic damages (pain, suffering, loss of enjoyment of life). Non-economic damages are calculated based on life expectancy and quality of life. Mr. Johnson has had four years of suffering since 2014 and will likely live only two more years. The calculation uses $1 million per year for suffering, resulting in $37 million in non-economic damages. The total compensatory damages are $39,553,209.23.

In defamation cases, damages include both economic losses (lost earnings) and non-economic losses (reputation, emotional distress). The video explains that the speaker calculated damages by projecting earnings from age 65, using conservative estimates of $80,000 per year even though the plaintiff hadn't worked much since the incident. The speaker describes the calculation process: 'I could suggest you pick out four point seven two point two you add them together that's only gonna be one line for bandages in this case.' The speaker also addresses non-economic damages including 'loss of reputation' and 'emotional distress,' stating that the plaintiff was 'on top of the world on top of the world respected in the community hero to everybody very successful football coach.' The speaker suggests that the jury should consider both past and future damages, including 'the next 28 years' of lost earnings and reputation.

Compensatory damages compensate victims for measurable economic losses including lost earnings and reduced life expectancy. The speaker presented exhibits showing Joe Gwynn's earnings history and life expectancy projections to calculate what he would have earned had he lived. The speaker noted there was no contradictory testimony regarding these calculations. Beyond monetary figures, compensatory damages also cover intangible losses such as the value of everyday companionship, household assistance, and future care. The speaker emphasized that these damages represent what the victim meant to their family and community, including the comfort of knowing someone will be present in old age. This illustrates how courts attempt to quantify both tangible financial losses and intangible emotional impacts in wrongful death cases.

Failure to diagnose lawsuit settlements are calculated by first identifying economic damages (past and future medical expenses, past and future wage losses), then calculating non-economic damages (physical pain and suffering, disability, mental anguish) by multiplying economic losses by a factor between 1-5, with more severe and permanent injuries resulting in higher settlements; wrongful death claims additionally include loss of lifetime income, funeral expenses, and loss of consortium.

Civil damages in legal cases consist of multiple components. Compensatory damages compensate for actual losses, including economic losses (such as unauthorized use of image) and non-economic losses (such as emotional distress). Punitive damages are additional monetary awards intended to punish the defendant for egregious conduct and deter similar behavior in the future. In this case, the total of $7 million included $5 million in compensatory damages ($2.5 million for unauthorized image use and $2.5 million for emotional distress) plus $2 million in punitive damages.
