Vicarious Liability — Master-Servant, Principal-Agent, Partners

Vicarious liability is the liability of one person for the tort of another. The general rule of the law of torts is that a person answers for his own wrongs and his own wrongs alone; vicarious liability is the principled exception. It runs in three settings: principal and agent, partners in a firm, and master and servant. In each, the law fixes a defendant other than the actual wrongdoer with joint and several liability, on the strength of a relationship between the two and a connection between the wrong and that relationship. The maxims are familiar — qui facit per alium facit per se (he who does an act through another is deemed to do it himself) and respondeat superior (let the principal be liable). Their justification is partly historical, partly social-policy: the master is the better risk-bearer, has the deeper pocket, and has the ability to spread loss through insurance.

This chapter takes each of the three relationships in turn, and concentrates on the part of the doctrine that does the heavy lifting in exam questions — the test for who counts as a servant, what falls within the “course of employment”, and how the rule survives express prohibitions and the lending of servants between employers. Issues of capacity that interact with this chapter are dealt with in capacity in tort; the State’s special position is treated in vicarious liability of the State; and the underlying conceptual frame is laid down in the chapter on the essentials of every tort.

The general principle

For the liability of A for the act of B to arise on a vicarious basis, three things must be present: (i) a relationship of a recognised kind between A and B; (ii) a wrongful act by B; and (iii) a connection between the wrong and the relationship. Where the requirements are met, the actual wrongdoer and the person made vicariously liable are joint tortfeasors and the plaintiff has a free hand in choosing whom to sue. Their liability is joint and several — the master may be sued for the whole. After paying, the master may seek indemnity from the servant; that aspect belongs to the chapter on joint and several tortfeasors. The doctrine is part of the broader scheme of tort liability and remedies introduced in the opening chapter.

Principal and agent

Where one person authorises another to commit a tort, both are liable. The maxim qui facit per alium facit per se is the classical anchor. The authority may be express (Ellis v. Sheffield Gas Consumers’ Co., (1853) 2 E. & B. 767) or implied (Poland v. John Parr & Sons [1927] 1 KB 236).

The leading authority is Lloyd v. Grace, Smith & Co. [1912] AC 716. Mrs. Lloyd, dissatisfied with the income from her two cottages, called at the office of Grace, Smith & Co., a firm of solicitors. The managing clerk advised her to sell the cottages and reinvest. He had her sign two documents which were in form sale deeds but in substance gift deeds in his own favour. He then disposed of the property and pocketed the proceeds. He acted entirely for his own benefit and entirely without the principal’s knowledge. The House of Lords nevertheless held the firm liable: the agent was acting within the scope of his apparent or ostensible authority, and the principal must answer for the fraud committed within that scope. The decision is the foundation of the modern rule that the principal cannot escape by showing that the agent was acting for his own benefit.

The contrast is State Bank of India v. Shyama Devi, AIR 1978 SC 1263. The plaintiff’s husband handed over cash and cheques to a friend who happened to be a bank employee, asking him to deposit them in the plaintiff’s account; no proper receipt was obtained; the friend misappropriated the funds. The Supreme Court held that the friend, in receiving the deposit informally outside the bank’s procedures, was acting in his private capacity as a friend, not in the scope of the bank’s employment, and the bank was not liable. The two cases together set the boundary: ostensible authority on the one hand, off-duty private capacity on the other.

Casual delegation and vehicle owners

The principal-agent doctrine embraces casual delegation. Ormrod v. Crosville Motor Service Ltd. [1953] 1 WLR 1120 is the textbook illustration: the owner of a car asked a friend to drive it from Birkenhead to Monte Carlo so that the two could use the car for a joint holiday. Shortly after leaving Birkenhead the friend caused an accident. The owner was held liable. As Denning L.J. explained, where a vehicle is on the road on the owner’s purpose, wholly or partly, the owner answers for the driver’s negligence; the owner only escapes when the vehicle is loaned for purposes in which the owner has no interest. Tirlok Singh v. Kailash Bharti, AIR 1986 P&H 155 illustrates the limit: a younger brother who took the motor cycle without the owner’s knowledge while the owner was abroad was not the owner’s agent.

Partners

The relationship between partners is one of mutual agency. The rules of the law of agency therefore apply to the firm’s liability for the torts of any one partner committed in the ordinary course of the business of the firm. Hamlyn v. Houston & Co. [1903] 1 KB 81 is the textbook authority: one of two partners, acting within the general scope of his authority as a partner, bribed the plaintiff’s clerk to divulge business secrets in breach of his contract of employment; both partners were liable for the wrongful inducement. Their liability, like that of master and servant, is joint and several.

Master and servant — the architecture

If a servant does a wrongful act in the course of his employment, the master is liable for it. The doctrine rests on respondeat superior. The two essentials are (i) that the wrongdoer is the master’s servant, and (ii) that the wrong was done in the course of employment. Each essential is a battlefield in itself.

Who is a servant — the control test and beyond

A servant is a person employed under a contract of service to do work under the directions and control of the employer. An independent contractor is engaged under a contract for services to produce a result, and has discretion as to how the result is to be achieved. The classical statement is in Performing Right Society Ltd. v. Mitchell & Booker (Palais de Danse) Ltd. [1924] 1 KB 762: the independent contractor “undertakes to produce a given result, but so that in the actual execution of the work, he is not under the order or control of the person for whom he does it”.

The pure control test is, however, too narrow for the modern world. A surgeon in a hospital and the captain of a ship are not subject to direction as to the manner in which they perform their professional acts; yet they are servants of the institution that employs them. Modern authority therefore supplements the control test with the “hire and fire” test, the integration test, and the broader question whether the worker is in business on his own account. Cassidy v. Ministry of Health [1951] 2 KB 343 is decisive on the hospital point: a hospital authority is liable for the negligence of its house surgeons, resident medical officers, nurses and part-time anaesthetists, even though it cannot direct them on matters of professional skill. As Denning L.J. observed, the authorities “take the benefit of the work when it is carefully done, and they must take the liability of it when it is negligently done”.

Independent contractors and the exceptions

The general rule that an employer is not liable for the torts of an independent contractor (Morgan v. Incorporated Central Council [1936] 1 All ER 404) is subject to recognised exceptions. An employer is liable: (i) where he authorises or ratifies the wrongful act (the employer is then a joint tortfeasor in his own right); (ii) where the work is of an extra-hazardous kind (Honeywill & Stein Ltd. v. Larkin Bros. Ltd. [1934] 1 KB 191); (iii) in cases of strict liability under Rylands v. Fletcher; (iv) where the act creates dangers on or near the highway (Tarry v. Ashton (1876) 1 QBD 314 — fall of a lamp overhanging the footway from the defendant’s house, attached by an independent contractor); (v) for nuisance involving withdrawal of support from neighbouring land (Bower v. Peate (1876) 1 QBD 321); and (vi) for breach of the master’s common-law duties to his own servants (Wilsons & Clyde Coal Co. v. English [1938] AC 57).

Lending of servants — the Mersey Docks rule

Mersey Docks & Harbour Board v. Coggins & Griffiths (Liverpool) Ltd. [1947] AC 1 is the leading authority on lending of servants. The Board owned mobile cranes and let them out, each driver supplied with the crane. The stevedores hired both crane and driver. Owing to the driver’s negligence while loading a ship, X was injured. The House of Lords held the Board liable as the general and permanent employer; the stevedores, although they could direct the driver as to which cargo to lift and where to set it down, had no power to direct how the crane was to be operated. The presumption is therefore that the general employer remains the master, and the burden of rebutting that presumption — by showing a true transfer of the right of control — rests on the lender. Lord Porter’s formulation captures the spirit: “the ultimate question is not what specific orders, or whether any specific orders, were given but who is entitled to give the orders as to how the work should be done.”

The Indian application is Rajasthan State Road Transport Corpn. v. K.N. Kothari, where the Supreme Court held that effective control over a driver, transferred along with the vehicle, makes the transferee vicariously liable even though the driver remains on the original owner’s payroll.

Course of employment

An act is within the course of employment if it is either (i) a wrongful act authorised by the master, or (ii) a wrongful and unauthorised mode of doing some act authorised by the master. Most exam-question contests turn on limb (ii). The classical statement is in Barwick v. English Joint Stock Bank, (1867) LR 2 Ex. 259: the master “has put the agent in his place to do that class of acts, and he must be answerable for the manner in which the agent has conducted himself”.

Negligence, mistake and excessive force

If a servant is careless in the performance of his duties, the master answers. The fork between Williams v. Jones, (1865) 3 H. & C. 602 and Century Insurance Co. v. Northern Ireland Road Transport Board [1942] AC 509 is instructive. In Williams, the carpenter who lit his pipe and set fire to the plaintiff’s shed was held to have done something unconnected with his employment; in Century Insurance, the petrol-lorry driver who struck a match while transferring petrol was held to have been doing his work negligently — the master was liable. The Century approach is now preferred. The contrast captures the idea: smoking while doing the job is part of doing the job; smoking instead of the job is not.

Mistake of the servant in protecting the master’s property is within the course of employment if the mistake is reasonable and the force used not grossly excessive. Poland v. Parr & Sons [1927] 1 KB 236: a carter, mistakenly but reasonably suspecting that boys were pilfering sugar, struck one of them; the boy fell and was run over. The act, though excessive, was not so excessive as to fall outside the class of acts the servant was authorised to do. Bayley v. Manchester, Sheffield & Lincolnshire Railway, (1873) LR 8 CP 148 makes the same point with the misguided porter who pulled a passenger out of a train under the mistaken belief that he was on the wrong train.

Fraud and theft of the servant

Lloyd v. Grace, Smith & Co. resolves the fraud question for principal and agent and the same logic carries over to master and servant: a fraud committed within the apparent or ostensible scope of the servant’s authority engages the master, even though the fraud was committed for the servant’s personal benefit. The course-of-employment test does not require an act for the master’s benefit.

Theft is harder. Cheshire v. Bailey [1905] 1 KB 237 once held that theft was always outside the course of employment. That position has been overturned by Morris v. C.W. Martin & Sons Ltd. [1966] 1 QB 716. Where a servant has been entrusted with the possession of goods bailed to the master, theft of those goods by that servant is within the course of employment — “what he was doing, albeit dishonestly, he was doing in the scope of his employment”, as Diplock L.J. put it. But where the goods are stolen by a servant to whom the goods had not been entrusted, the theft is outside the course of employment and the master is not liable. The rule is one of entrustment.

Acts outside the course of employment — frolics and detours

The classical phrase is “a frolic of his own” — coined in Joel v. Morison, (1834) 6 C. & P. 501. The doctrine distinguishes a detour (a deviation from the master’s business which remains incidental to it) from a frolic (a wholly independent journey on the servant’s own account). Storey v. Ashton, (1869) LR 4 QB 476 is the textbook frolic: the carman, on his way back to the master’s office, was induced by another employee to turn off in a different direction to pick up something for that employee; while on this new journey he caused an accident; the master was not liable, since the carman had “started on an entirely new journey on his own or his fellow-servant’s account”. Hilton v. Thomas Burton (Rhodes) Ltd. [1961] 1 WLR 705 makes the same point: workmen who travelled seven miles for tea were on a frolic and the master was not liable for the negligence of one of them on the way back. Beard v. London General Omnibus Co. [1900] 2 QB 530 closes the circle from the other direction: where the conductor (whose duty did not include driving) drove the bus to turn it around at the end of the journey and caused an accident, the master was not liable, because the conductor was doing an act of a class he was not employed to perform at all.

Negligent delegation by the servant

Where the servant negligently delegates his authority to another to do the master’s work, and the delegate’s negligent performance causes harm, the master is liable — not because the delegate was acting in the course of employment, but because the servant’s own negligence in delegating is the effective cause of the accident. Ricketts v. Thomas Tilling Ltd. [1915] 1 KB 644 is the classical authority — the driver who allowed the conductor to drive negligently. The Indian application appears in cases like Baldeo Raj v. Deowati, AIR 1986 P&H 28 (driver allowed conductor to drive the truck), Engelhart v. Farrant & Co. [1897] 1 QB 240 (driver leaving cart in care of an untrained boy), and Sitaram v. Santanuprasad, AIR 1966 SC 1697, where the Supreme Court explained the limits — the master is not liable where the servant lends the vehicle to a third person for a purpose entirely outside the master’s business.

Effect of express prohibition

An act done in defiance of the master’s express instructions is not for that reason alone outside the course of employment. If express prohibition were a defence, every employer could escape liability by issuing prohibitions. Limpus v. London General Omnibus Co., (1862) 1 H. & C. 526 is the leading authority: the driver, in defiance of express instructions not to race or obstruct rival omnibuses, did exactly that and caused an accident. He was driving — that is what he was employed to do — and the master answered. The position was different in Twine v. Beans Express Ltd. [1946] 1 All ER 202: the driver of a commercial van who, in defiance of two express prohibitions, gave a lift to an unauthorised passenger, was acting outside the scope of his employment to that extent — “giving a lift to a person who has no right whatsoever to be there”.

The Indian trend has been to read course-of-employment more generously than Twine. The Punjab & Haryana High Court in its Full Bench decision in Prithi Singh v. Binda Ram, AIR 1987 P&H 234 overruled its earlier contrary view and held that where the driver was otherwise acting in the course of the master’s business, the additional act of giving an unauthorised lift in violation of a statutory rule does not place the act outside the course of employment. Similar lines are taken in Mariyam Jacob v. Hematlal, AIR 1982 Guj. 75 and Narayanlal v. Rukhmanibai, AIR 1979 MP 79. The Supreme Court’s own decision in Pushpabai v. Ranjit Ginning & Pressing Co., AIR 1977 SC 1735 supports the broader view: giving a lift to a fellow employee was within the ostensible authority of the manager driving on company business. The general principle that emerges is robust: prohibitions narrow the manner of doing the work; they do not narrow the class of work. The reasoning is parallel to that under the rules of private defence — once the act is within the class authorised, excessive use of force does not by itself displace the privilege.

The doctrine of common employment — historical

The doctrine of common employment, first applied in Priestley v. Fowler, (1837) 3 M. & W. 1, was an exception to respondeat superior: a master was not liable for harm done by one servant to a fellow servant in the course of their common employment. The doctrine was widely criticised, narrowed by judicial decisions, and finally abolished in England by the Law Reform (Personal Injuries) Act, 1948. In India, the Privy Council in Governor General in Council v. Constance Zena Wells, AIR 1950 PC 22 had still recognised the doctrine, but Section 3 of the Employers’ Liability Act, 1938 was amended in 1951 to abolish it. The Workmen’s Compensation Act, 1923 (now the Employees’ Compensation Act), the Employees’ State Insurance Act, 1948 and the Motor Vehicles Act, 1988 (no-fault liability under Section 140) further sideline the issue. The doctrine is now of historical importance only.

Connecting threads

Vicarious liability is at its core a question about the right defendant. The plaintiff must still show that a tort has been committed in the first place — the underlying tort, whether it be negligence, conversion, fraud or trespass, must be made out on its own elements. The doctrine simply identifies who answers. The chapter therefore reads alongside the substantive torts and the doctrines of inevitable accident and act of God which may negate the underlying liability altogether, and alongside the broader rule against damnum sine injuria when no legal injury is established at all. Where the State is the defendant, the further filter of sovereign / non-sovereign function applies, and the law in the law of torts on State liability turns on a different set of authorities — to which the next chapter is dedicated.

Frequently asked questions

Does the master remain liable when the servant acts in defiance of express instructions?

Yes, generally so. Limpus v. London General Omnibus Co. is the leading authority: the driver who raced rivals in defiance of express prohibitions was driving — that was the class of act he was employed to perform — and the master answered. Express prohibitions narrow the manner of doing the work, not the class of work. The position differs only where the prohibited act takes the servant outside the class of acts entrusted to him; Twine v. Beans Express on giving lifts is the textbook contrast. Indian courts have read this more generously: see Prithi Singh v. Binda Ram and Pushpabai v. Ranjit Ginning & Pressing Co.

What is the difference between a frolic and a detour?

A detour is a deviation from the master's business which remains incidental to it — the servant takes a roundabout route home, or stops briefly for a permitted purpose. The master is still liable. A frolic, in the language of Joel v. Morison, is a wholly new journey on the servant's own account, severed from the master's business. Storey v. Ashton is the canonical illustration: a carman who turned aside on a fellow-employee's errand had embarked on an entirely new journey, and the master was not liable. The line is between deviation within the master's enterprise and a separate enterprise of the servant's own.

Why is a hospital liable for the negligence of a surgeon it cannot direct on matters of skill?

Because the modern test for who counts as a servant is no longer pure control. As Cassidy v. Ministry of Health holds, the hospital is liable for the negligence of its house surgeons, resident medical officers, nurses and part-time anaesthetists alike. The relevant tests are who pays, who can dismiss, and who has integrated the worker into the institution's organisation. As Denning L.J. put it, the hospital takes the benefit of the work when carefully done and must take the liability when negligently done. The Hillyer position has not survived.

Is a principal liable for fraud committed by an agent for the agent's own benefit?

Yes, if the fraud is committed within the scope of the agent's apparent or ostensible authority. Lloyd v. Grace, Smith & Co. is decisive: the managing clerk of the firm of solicitors defrauded the client wholly for his own benefit, and the firm was held liable because he was acting within his apparent authority. The course-of-employment test does not require that the act be for the master's benefit. The principle is sharply limited where the agent is acting in a private capacity off-duty (State Bank of India v. Shyama Devi).

Who is the master when one employer lends a servant to another?

There is a presumption that the general employer remains the master and that only services, not control, have been transferred. The presumption can be rebutted, but the burden is heavy. The leading authority is Mersey Docks & Harbour Board v. Coggins & Griffiths (Liverpool) Ltd.: the Board, as the general and permanent employer of the crane driver, was held liable; the stevedores' immediate control over particular cargo did not amount to a transfer of the right to direct how the crane was to be operated. The Supreme Court applied the same principle in Rajasthan State Road Transport Corpn. v. K.N. Kothari.

Is the master liable when a servant steals property bailed to the master?

It depends on entrustment. Morris v. C.W. Martin & Sons holds that where the master has entrusted the bailed goods to the very servant who steals them, the theft is within the course of employment and the master is liable — the servant was discharging his duty of taking care of the goods, and his manner of doing so was to convert them. But if the goods are stolen by a servant who was not entrusted with them, the theft is outside the course of employment and Cheshire v. Bailey reasoning still applies.
