Estimated study time: 40–50 minutes
This Nature and purpose of vicarious liability A-Level Law revision page introduces the OCR rules governing liability for the tort of another person. Vicarious liability commonly arises where an employer may be held legally responsible for a tort committed by an employee, although OCR also requires you to study relationships that are akin to employment. The topic combines rules about the relationship between the parties with rules connecting the wrongdoing to that relationship. Understanding this foundation will make the later lessons on employment status [Lesson 133. Employment status] and course of employment [Lesson 135. Course of employment] much easier to apply.
Learning Objectives 🎯

Nature and purpose of vicarious liability A-Level Law revision overview
OCR requires students to study the:
nature and purpose of vicarious liability
liability for employees
traditional tests of employment status
relationships akin to employment
liability for torts committed in or outside the course of employment
liability for torts closely connected to employment.
This lesson concentrates on the overall idea and purpose of vicarious liability. The detailed tests are developed in Lessons 133 to 136.
What is vicarious liability?
Vicarious liability occurs where one party, usually an employer, is held legally responsible for a tort committed by another party, usually an employee.
OCR's 2024 and 2025 mark schemes describe it as one party taking legal responsibility for the tort of another.A simple structure is:
Tortfeasor commits tort → claimant suffers harm → third party may be held vicariously liable
For example:
A delivery driver negligently injures a pedestrian while carrying out work for a delivery company.
The driver is the person whose negligence caused the injury. However, if the rules of vicarious liability are satisfied, the delivery company may also be held legally responsible for that tort.
Vicarious liability is not itself a tort
This is a particularly important distinction.
Vicarious liability is not a separate tort.
It is a form of liability for a tort committed by another person.
OCR's 2023 examiner report specifically identified this as a misconception among candidates.
The underlying tort might, for example, be:
negligence
an intentional tort.
The claimant must first be able to identify a tort committed by the tortfeasor.
You should therefore avoid writing:
"The employee committed the tort of vicarious liability."
That is legally incorrect.
Instead:
"The employee committed a tort. The question is whether the employer is vicariously liable for that tort."
The three parties
OCR mark schemes use three important terms.
Party | Role |
Claimant (C) | The person who suffers harm caused by the tort. |
Tortfeasor (TF) | The person who commits the tort and causes the harm. |
Defendant (D) | The third party whom the claimant seeks to hold vicariously liable for the tortfeasor's tort. |
Example
Farah is a pedestrian. Kai is employed as a delivery driver by QuickDrop Ltd. While making deliveries, Kai negligently injures Farah.
The parties are:
Farah: claimant
Kai: tortfeasor
QuickDrop Ltd: potential defendant for the purposes of vicarious liability.
📌 Exam technique: Identifying these parties at the beginning of a problem question helps keep the analysis clear.
A tort must have been committed
Vicarious liability depends upon wrongdoing by the tortfeasor.
OCR's 2024 mark scheme expressly states that a tort must be committed by the tortfeasor.
This means that vicarious liability does not create a tort where none already exists.
The structure is:
The tortfeasor commits a tort.
The claimant suffers the relevant harm.
The law then considers whether another party should bear responsibility for that tort.
For example, if an employee has committed negligence, the separate issue is whether the employer should be vicariously liable for that negligence.
The two broad requirements
Modern OCR materials describe vicarious liability through two broad requirements.
There must be:
a relationship between the defendant and tortfeasor which makes it proper for the law to make the defendant bear responsibility for the tortfeasor's fault, and
a sufficient connection between that relationship and the tortfeasor's wrongdoing.
OCR's 2025 mark scheme identifies this two-part approach with Barry Congregation of Jehovah's Witnesses v BXB, while earlier materials use Barclays Bank plc v Various Claimants as the framework for the modern approach.You do not need to master the detailed rules for either part yet. At this stage, understand the structure.
Requirement 1: the relevant relationship
The first question is:
What is the relationship between the tortfeasor and the potential defendant?
The classic situation is:
Employer → employee
The traditional approach therefore asks whether the tortfeasor is an employee.
OCR requires students to know the basic tests used to establish employee status. These are covered in employment status [Lesson 133. Employment status].
However, vicarious liability is not limited to traditional employment relationships.
OCR also requires study of newer approaches for tortfeasors who do not fit the classic employer-employee relationship.
These relationships are examined in relationships akin to employment [Lesson 134. Relationships akin to employment].
Requirement 2: connection with the wrongdoing
Establishing the right relationship does not automatically make the defendant liable for everything the tortfeasor does.
There must also be a sufficient connection between:
the relationship, and
the tort committed.
Traditionally, this is expressed through asking whether the tort was committed in the course of employment.
For unintentional torts, OCR requires students to study the Salmond test, including circumstances where an employee acts:
within the course of employment
outside the course of employment.
This is developed fully in course of employment [Lesson 135. Course of employment].
OCR also requires the modern approach to torts that are closely connected with employment, which is developed in closely connected torts [Lesson 136. Closely connected torts].
The basic structure to remember
At this stage, the full topic can be visualised as:
Has TF committed a tort?
↓
Requirement 1: Is there the required relationship between D and TF?
↓
Requirement 2: Is TF's wrongdoing sufficiently connected to that relationship?
↓
If both requirements are established, D may be vicariously liable.
This structure is much safer than memorising individual cases without understanding where they fit.
Traditional and modern approaches
OCR requires both traditional and more modern approaches to vicarious liability.
A useful overview is:
Issue | Traditional approach | Modern development |
Relationship | Is the tortfeasor an employee? | Can certain relationships be treated as akin to employment? |
Connection with wrongdoing | Was the tort committed in the course of employment? | Is the tort sufficiently closely connected to the employment relationship? |
The detailed rules belong in the next four lessons. For now, the key point is that both sides of the vicarious liability relationship must be considered.
When might vicarious liability arise?
The most obvious circumstances involve an employee committing a tort connected with their work.
Example 1: negligent work
A delivery driver negligently drives a company vehicle while making deliveries and injures a pedestrian.
Potential vicarious liability is raised because:
a tort has been committed
there is an employment relationship
the wrongdoing takes place while the employee is carrying out work.
Whether the exact requirements are satisfied would be determined using the rules studied later.
Example 2: an unauthorised way of doing an authorised job
An employee is carrying out a job for their employer but performs it carelessly or in an unauthorised manner, injuring someone.
This can still raise vicarious liability.
OCR materials identify cases such as Century Insurance v Northern Ireland Transport Board and Limpus v London General Omnibus in relation to negligent or unauthorised ways of performing employment duties.
The detailed Salmond rules are considered in [Lesson 135. Course of employment].
Example 3: conduct outside the employee's work
An employee stops carrying out work for their employer and instead pursues a completely personal activity during which they commit a tort.
This may fall outside vicarious liability because the necessary connection with employment may be missing.
OCR materials describe this as potentially being on a "frolic of his own".
Again, the detailed rule belongs to later lessons, but the example shows that employment alone is not enough.
Example 4: a non-traditional relationship
A person carries out activities for an organisation but is not obviously employed under a conventional employment contract.
Vicarious liability may still need to be considered because OCR requires the akin to employment approach for relationships that do not fit the traditional model.
This is the focus of [Lesson 134. Relationships akin to employment].
Example 5: intentional wrongdoing connected to work
Vicarious liability is not restricted to careless conduct.
A tortfeasor may commit an intentional tort, and the issue may then be whether the wrongdoing is sufficiently closely connected to the field of activities entrusted to that person.
OCR's 2025 assessment tested precisely this type of situation.
The detailed test is studied in [Lesson 136. Closely connected torts].
Employment alone does not establish vicarious liability
A common mistake is to reason:
"TF works for D, so D is liable."
That is incomplete.
Two requirements must be considered.
Even where the relationship requirement is clearly satisfied, there must still be sufficient connection between the relationship and the wrongdoing.
For example:
An employee commits a tort while pursuing a purely personal vendetta unrelated to the activities entrusted to them.
The fact that the person happens to be an employee does not by itself establish liability.
OCR's 2025 mark scheme uses WM Morrisons Supermarkets plc v Various Claimants to illustrate circumstances in which an employee's personal vendetta may fall outside the required connection.
Place and time are not the whole test
Similarly, do not assume that vicarious liability arises simply because:
the tort occurred at work
the tort occurred during working hours.
OCR's 2025 examiner report warns that candidates sometimes focused too narrowly on place and time. The relevant question is the connection between the activities entrusted to the tortfeasor and the tort committed.
This will become especially important when you study closely connected torts [Lesson 136. Closely connected torts].
What is the purpose of vicarious liability?
Vicarious liability can make one person responsible even though another person actually committed the tort.
This raises an obvious question:
Why should the law impose liability on someone who did not personally commit the tort?
OCR assessment materials identify several policy reasons.
Providing effective compensation
One important purpose is helping an injured claimant obtain compensation.
An individual tortfeasor may have limited financial resources. An employer is often better placed to meet a damages award and may be insured.
OCR mark schemes identify the employer's greater ability to bear the loss and the availability of insurance as reasons supporting vicarious liability.
Without vicarious liability:
A claimant might prove that an employee committed a tort but still struggle to obtain effective compensation from that individual.
Vicarious liability can therefore support the compensatory purpose of tort law.
The principles governing the calculation of compensation are studied later in compensatory damages [Lesson 140. Compensatory damages].
The employer benefits from the employee's work
Another justification is that employers benefit from the activities carried out by employees.
OCR mark schemes identify the idea that because employers benefit financially from employees' work, it can be fair for them to bear responsibility for torts arising from work-related activity.
The reasoning is:
Employer receives benefit from activity → activity creates risks → employer may fairly bear losses resulting from those work-related risks
This does not mean that every act committed by an employee makes the employer liable.
The ordinary vicarious liability requirements must still be satisfied.
The employer creates or introduces the risk
Employing people to carry out activities inevitably creates some risk of tortious conduct.
OCR's modern materials recognise the importance of considering the risk created by the activities undertaken on behalf of the defendant.
For example:
A business sends drivers onto public roads to make deliveries.
The business benefits from the delivery operation, but that operation also creates risks connected with driving.
Vicarious liability can place responsibility for work-created risks upon the enterprise associated with them, provided the legal requirements are met.
Control and responsibility
OCR's evaluation material also identifies the employer's control over employees as a justification for liability.
Employers may have responsibilities connected with:
selecting employees
supervising them
training them
setting working practices.
Because the employer organises and benefits from the work, it can be fair for the employer to take responsibility for torts sufficiently connected with that work.
However, the extent of employer control can vary, which becomes relevant when evaluating the fairness of the doctrine in [Lesson 137. Evaluating vicarious liability].
Encouraging safer working practices
Vicarious liability may also encourage organisations to maintain high standards.
OCR materials explain that liability can encourage employers to:
minimise risks
promote safe practices
avoid poor working practices
avoid ignoring foreseeable problems.
The possibility of liability therefore provides an incentive for employers to organise activities carefully.
This links vicarious liability to the broader tort law aim of discouraging harmful conduct.
Spreading the financial loss
Employers and organisations are often better able than individual tortfeasors to absorb or distribute the financial impact of liability.
OCR's mark schemes note that employers may:
have greater financial resources
have insurance
distribute costs through the business.
This provides a practical reason for placing responsibility on an employer rather than relying exclusively upon the individual employee who committed the tort.
Fairness and justice
The overall purpose of vicarious liability also raises questions of fairness and justice.
There are competing interests:
the injured claimant wants effective compensation
the employee is the person who actually committed the tort
the employer may not personally have been at fault
the employer may nevertheless benefit from and create the risks associated with the work.
OCR expressly assesses fairness in relation to vicarious liability, and its mark schemes recognise both arguments supporting and criticising the doctrine.
Those competing arguments are explored fully in evaluating vicarious liability [Lesson 137. Evaluating vicarious liability].
Purpose summary
The main policy reasons identified in OCR materials can be summarised as follows:
Purpose or justification | Explanation |
Compensation | Employers may be better able to compensate injured claimants than individual tortfeasors. |
Employer benefit | Employers benefit from work carried out on their behalf. |
Risk allocation | Work activities create risks, so responsibility may be placed on the organisation associated with those risks. |
Control and responsibility | Employers organise, supervise and train workers and may therefore fairly carry responsibility for work-related torts. |
Safer practices | Potential liability encourages organisations to minimise risks and maintain good working practices. |
Loss distribution | Businesses may be better placed to insure against and distribute the financial cost of liability. |
These are reasons why the doctrine exists. They do not replace the legal tests needed to establish whether vicarious liability actually arises.
Purpose is different from the legal test
This distinction matters in examinations.
Suppose:
A company has significant financial resources and insurance.
That may help explain why vicarious liability is justified as a doctrine, but it does not automatically prove that the company is vicariously liable in a particular scenario.
Liability still requires:
the appropriate relationship
a sufficient connection with the tortfeasor's wrongdoing.
Keep policy reasoning and legal requirements separate.
A basic vicarious liability checklist
At this stage of the course, use the following overview whenever you see a potential vicarious liability scenario:
Has someone committed a tort?
Who is the claimant?
Who is the tortfeasor?
Who is the potential vicariously liable defendant?
What is the relationship between D and TF?
Is there a sufficient connection between that relationship and the wrongdoing?
Which detailed test will be needed?
traditional employment status
akin to employment
course of employment
close connection.
Reach a conclusion only after applying the relevant detailed rules.
The next four lessons supply those detailed rules.
Worked introductory example
Consider:
Maya works as a delivery driver for ParcelFast Ltd. While carrying out deliveries, Maya drives negligently and injures Lewis, a pedestrian.
At this stage, you can identify:
The underlying tort
Maya has allegedly committed negligence.
The parties
Lewis: claimant
Maya: tortfeasor
ParcelFast Ltd: potential vicariously liable defendant.
Relationship requirement
Maya is described as working for ParcelFast Ltd.
The precise employment-status rules will be covered in employment status [Lesson 133. Employment status].
Connection requirement
The negligence occurs while Maya is carrying out deliveries.
This raises the question whether the tort occurred in the course of employment, which is examined in [Lesson 135. Course of employment].
Purpose
Holding ParcelFast responsible, if the requirements are established, may support:
compensation of Lewis
allocation of work-related risks to the business benefiting from the activity
encouragement of safe working practices.
Conclusion
The facts clearly raise the possibility of vicarious liability, but the detailed legal tests must be applied before liability can finally be established.
A contrasting example
Maya finishes work and uses her own car for an entirely personal journey. During that journey she negligently injures Lewis.
Maya may still personally have committed negligence.
However, the connection between that tort and her employment is much weaker.
The fact that she remains employed by ParcelFast does not automatically make the company vicariously liable.
This illustrates why the relationship and the connection with wrongdoing are separate requirements.

Claimant | The person who has suffered the harm caused by the tort. | Identify who is seeking compensation. |
Defendant | The third party whom the claimant seeks to hold vicariously liable for the tortfeasor's wrongdoing. | Distinguish the employer or organisation from the person who actually committed the tort. |
Course of employment | The connection between an employee's conduct and their employment which may allow liability to be imposed on the employer. | Identify the second broad issue before applying the detailed rules in later lessons. |
Hints from the Examiner Reports 💡
Examiner hint: Do not describe vicarious liability as a tort. OCR's 2023 report specifically identified this as a misconception. Vicarious liability is a form of liability for a tort committed by another person.
Examiner hint: Start with the basis of the doctrine and its two-part structure. OCR's 2024 report states that successful answers needed to explain the basis of vicarious liability and the two requirements before applying the relevant rules.
Examiner hint: Explain rather than merely state. OCR's 2025 report identified weaker answers that stated legal rules without explaining them. A definition should be followed by an explanation of how the relationship and connection requirements operate.
Examiner hint: Read exclusions in the question carefully. In 2024 and 2025, many candidates wasted time discussing employment status even though the question expressly told them not to.
Examiner hint: Do not decide liability simply by asking where or when the tort occurred. OCR's 2025 report warns that being on the employer's premises or within working hours is not conclusive. The legal connection between the person's activities and their wrongdoing matters.
Examiner hint: Keep AO1 relevant and structured. OCR's 2023 report found that stronger vicarious liability answers showed an understanding of both the traditional and modern approaches rather than relying on isolated cases without an overall legal framework.
Common Mistakes ⚠️
Mistake: Saying vicarious liability is a tort
Why this is incorrect: The tort is committed by the tortfeasor. Vicarious liability is the legal mechanism by which another person may also be held responsible for that tort.
How to improve: Use the wording:
Vicarious liability is liability for the tort of another person.
Then identify the actual tort separately.
Mistake: Assuming an employer must have personally done something wrong
Why this is incorrect: The central feature of vicarious liability is that the defendant may be held responsible for a tort actually committed by the tortfeasor.
How to improve: Keep the parties separate. Identify who committed the tort and who is being asked to bear vicarious responsibility.
Mistake: Assuming employment automatically creates liability
Why this is incorrect: Vicarious liability involves two broad requirements. A relevant relationship must exist, but there must also be a sufficient connection between that relationship and the wrongdoing.
How to improve: Always write the two-stage structure before reaching a conclusion.
Mistake: Treating "course of employment" as meaning only working hours
Why this is incorrect: OCR's examiner reports make clear that time and place are not conclusive.
How to improve: Ask how the tort relates to the activities entrusted to the tortfeasor rather than relying only on a clock or location.
Mistake: Treating compensation or insurance as the legal test
Why this is incorrect: These help explain the purpose and policy of vicarious liability. They do not establish liability in a particular case.
How to improve: Separate:
Why does vicarious liability exist?
Are the legal requirements satisfied here?
Mistake: Confusing "akin to employment" with ordinary employment
Why this is incorrect: OCR requires both traditional employment relationships and newer approaches to relationships which do not fit the classic employer-employee model.
How to improve: First determine what sort of relationship the facts raise, then select the appropriate approach in [Lesson 133. Employment status] or [Lesson 134. Relationships akin to employment].
Mistake: Calling independent contractor status or a "frolic of one's own" a defence
Why this is incorrect: OCR's 2023 examiner report expressly states that these are not defences. They concern whether the requirements of vicarious liability have been established in the first place.
How to improve: Treat them as part of the liability analysis rather than as defences raised after liability has been established.

Indicative answers and mark scheme
Question 1
Award up to 2 marks for explaining that:
one party, usually an employer
may be held legally responsible for a tort committed by another party, usually an employee.
Do not credit an answer that incorrectly describes vicarious liability itself as a tort unless the error is corrected.
Question 2
Award 1 mark each for accurately identifying:
claimant: person who suffers the harm
tortfeasor: person who commits the tort
defendant: third party whom the claimant seeks to hold vicariously liable.
Question 3
Award up to 4 marks for explaining:
there must be a relationship between D and TF which is capable of making it proper for D to bear responsibility for TF's fault
there must be a sufficient connection between that relationship and TF's wrongdoing.
Appropriate reference may be made to Barry Congregation of Jehovah's Witnesses v BXB or Barclays Bank plc v Various Claimants.
Question 4
Award up to 4 marks for two developed purposes, for example:
helping ensure that injured claimants can obtain effective compensation
placing the financial consequences of work-created risks upon an employer benefiting from the activity
encouraging safer working practices
reflecting an employer's responsibility for organising, supervising and training workers
allowing loss to be borne by an organisation which may have greater financial resources and insurance.
Maximum marks require explanation rather than a list.
Question 5
Award 1 mark each:
Amira: claimant
Ben: tortfeasor
Cargo Ltd: potential vicariously liable defendant.
Question 6
Award up to 6 marks for explaining that:
employment by itself is insufficient
a tort must first have been committed by the tortfeasor
there are two broad requirements
the appropriate relationship must exist
there must also be a sufficient connection between the relationship and the wrongdoing
conduct entirely outside the employment relationship may therefore fall outside vicarious liability.
A developed answer may refer to the later distinction between conduct in the course of employment and a worker being on a frolic of their own.
Question 7
Award up to 6 marks for three developed reasons.
Possible content includes:
Compensation
The employer may have greater resources or insurance, making effective compensation more realistic for the claimant.
Benefit and risk
The employer benefits from the employee's work and may fairly bear losses generated by risks associated with that work.
Safer practices
The possibility of liability may encourage employers to supervise, train and organise work in ways that minimise harm.
Control and responsibility
Employers organise work and exercise varying degrees of control over those carrying it out.
Distribution of loss
A business may be better able to insure against or distribute the cost than an individual tortfeasor.
Credit any three accurately explained OCR-supported purposes.
Question 8
A strong answer should distinguish the two incidents.
First incident
Nia commits an alleged tort of negligence while delivering parcels.
The parties would be:
Omar as claimant
Nia as tortfeasor
Speedy Parcels Ltd as the potential vicariously liable defendant.
There is an apparent employment relationship, and the negligence takes place while Nia is carrying out the activity entrusted to her by Speedy Parcels.
The facts therefore clearly raise both broad requirements of vicarious liability.
The precise question of whether the tort occurred in the course of employment will be resolved using the rules developed in [Lesson 135. Course of employment].
Second incident
Nia is still an employee, but that fact alone is not enough.
At the time Petra is injured:
Nia has finished work
she is using her own car
she is travelling for a personal purpose.
The facts therefore raise a much more difficult issue concerning the necessary connection between the employment relationship and the tort.
The company does not become liable merely because Nia remains its employee.
Conclusion
Both incidents involve negligence committed by the same employee, but vicarious liability depends on more than employment status. The first tort appears closely linked to the work being carried out for Speedy Parcels, while the second appears connected to a personal activity. A full legal conclusion would require the detailed course of employment rules studied in the later lesson.
