Acts Outside the Course of Employment
Under tort law, an employer is vicariously liable only for acts committed within the course of employment.
If an employee embarks on a purely personal side-trip, or “frolic of his own,” the employer is not liable.
While minor detours remain within the scope of employment, a separate personal journey breaks the employment connection.
In Storey v. Ashton, a delivery driver abandoned his return journey to perform a personal errand for a co-worker and caused an accident.
The court held that because the driver had departed from his employer’s business and was acting for personal purposes, the employer was not vicariously liable.
Beard v. London General Omnibus Co.
Under the doctrine of vicarious liability, an employer is liable only when an employee acts within the course of employment.
If an employee performs an unauthorized act completely outside their assigned duties, the employer is not liable.
In Beard v. London General Omnibus Co., a ticket conductor negligently drove a bus while the driver was away, injuring a pedestrian.
The court held that the bus company was not vicariously liable because driving was outside the conductor’s duties, making it an unauthorized act, not an improper mode of performing his work.
Likewise, if a stranger drives the vehicle and causes an accident, the master is not liable, as no master-servant or agency relationship exists.
Negligent Delegation of Authority by the Servant
Under the principle of negligent delegation of authority, a master remains vicariously liable where a servant carelessly delegates their duties to a third party who causes harm.
Liability arises because the servant’s delegation itself is an unauthorized mode of performing assigned duties, not because the third party acted in the course of employment.
Thus, if a bus driver allows an unauthorized person to drive and an accident occurs, the employer is liable because the servant’s negligent delegation is the effective legal cause of the accident.
Ricketts v. Thomas Tilling Ltd.
The key distinction between Ricketts v. Thomas Tilling Ltd. and Beard v. London General Omnibus Co. is negligent delegation of authority.
In Ricketts, the driver allowed the conductor to drive while remaining present, making his failure to supervise a negligent mode of performing his duties, and the employer was vicariously liable.
In Beard, the driver was away and unaware that the conductor had taken the bus, so no negligence could be attributed to him.
Thus, although the conductor acted outside the scope of employment in both cases, the master is liable only where the employee negligently delegates authority.
Headmistress, Govt. Girls High School v. Mahalakshmi
In Headmistress, Govt. Girls High School v. Mahalakshmi, the doctrine of negligent delegation of authority made the school authorities and the State vicariously liable.
The school’s Aya, whose duty was to provide drinking water, improperly delegated the task to a 9th-standard student.
While securing the water pot to a bicycle, the carrier spring struck the student’s eye, causing permanent loss of vision.
The court held that the Aya’s delegation was a negligent mode of performing her employment duties, making the school management and the State liable, and awarded ₹58,000 as compensation.
Baldeo Raj v. Deowati
In Baldeo Raj v. Deowati, the court applied the principle of negligent delegation of authority to hold the vehicle owner vicariously liable.
The authorized truck driver allowed the conductor to drive while sitting beside him, and the conductor negligently hit a rickshaw, causing a passenger’s death.
The court held that allowing an unauthorized person to drive was a negligent mode of performing the driver’s duties, making the vehicle owner vicariously liable for the resulting loss of life.
Indian Insurance Co. v. Radhabai & Amruta Dei v. State of Orissa
Under the law of torts, a master, including the State Government, is vicariously liable where a servant adopts an unauthorized mode of performing an authorized duty or negligently permits unauthorized delegation.
In Indian Insurance Co. v. Radhabai, a government driver allowed an unauthorized person to drive, causing an accident, and the State Government was held liable.
Likewise, in Amruta Dei v. State of Orissa, the government was held liable because an R.T.O. officer failed to prevent an unauthorized person from driving an official jeep.
In both cases, the courts held that active negligent delegation or failure to supervise during the course of employment binds the employer to vicarious liability.
Gyarsi Devi v. Sain Das
In Gyarsi Devi v. Sain Das, the court applied the principles of vicarious liability and negligent delegation of authority.
A truck driver, assigned to deliver stones, left for a meal and instructed the cleaner to drive the truck.
The cleaner drove negligently, causing a fatal accident.
The court held the employer vicariously liable because:
(1) the driver negligently delegated his authority to an unauthorized cleaner, and
(2) the cleaner was performing the employer’s business of delivering goods within the course of employment.
Ilkiw v. Samuels
In Ilkiw v. Samuels, the doctrine of negligent delegation of authority made the employer vicariously liable after an employed lorry driver allowed a stranger to drive the employer’s truck.
The stranger drove negligently and caused an accident.
The court held that the employer’s liability arose from the driver’s own negligence in handing over control of the vehicle to an unauthorized person, which was a careless mode of performing his employment duties.
Gwilliam v. Twist
In Gwilliam v. Twist, a bus driver stopped by a police officer for suspected intoxication allowed a stranger to drive the bus home, and the stranger negligently injured a pedestrian.
The court held the employer not vicariously liable, finding that the emergency did not create implied authority to delegate driving to an unauthorized person.
However, legal analysis suggests that the result turned on a procedural gap: the plaintiff argued implied authority, not negligent delegation of authority.
Had the claim been based on the driver’s careless surrender of control of the vehicle, the master might have been held vicariously liable.
Kilari Mammi v. Barium Chemicals Ltd.
In Kilari Mammi v. Barium Chemicals Ltd., the court applied the principle of vicarious liability where a jeep driver left the ignition key in the vehicle while visiting a tailor.
An unauthorized person took the jeep and caused an accident.
The court held the employer liable, ruling that the driver’s failure to secure the vehicle was negligence committed in the course of employment.
Leaving the key in the ignition directly enabled the unauthorized driving and resulting accident.
Engelhart v. Farrant & Co.
In Engelhart v. Farrant & Co., the court held the employer vicariously liable where a delivery cart driver, despite instructions not to leave the cart unattended, left it with an untrained boy.
The boy attempted to drive the cart and caused an accident.
Although the boy acted outside the scope of employment, the driver’s decision to entrust the cart to an unqualified person was an unauthorized and negligent mode of performing his duties.
Consequently, the master was held liable for the resulting damage.
Sitaram v. Santanuprasad
In Sitaram v. Santanuprasad, the Supreme Court held that a vehicle owner is not vicariously liable where a servant delegates control of the vehicle for a third party’s personal purpose outside the course of employment.
A taxi driver allowed a cleaner to drive the taxi for a driving test, during which the cleaner negligently injured a pedestrian.
The Court distinguished the case from Ricketts, holding that the cleaner was pursuing his own personal purpose, not the master’s business, and the driver had no authority to lend the taxi.
Thus, a master is liable only when the servant commits a tort or breaches a supervisory duty while furthering the master’s business, not when the vehicle is used for an unauthorized personal errand.
