Res ipsa loquitur, vicarious liability and passenger insurance cover shape liability for negligent driving on business use.

Negligence may be inferred under res ipsa loquitur where a vehicle on a straight road swerves to the wrong side and strikes a tree, causing death, and no non-negligent explanation is shown. A master is vicariously liable when the servant's negligent driving occurs during a business journey and in the course of employment, including conduct that is a wrongful mode of doing an authorised act. Motor insurance cover for passenger death depends on the statutory scheme and the express policy terms, so liability is confined to the passenger-risk cover specifically undertaken under the policy.

Issues: (i) whether the accident and the driver's negligence could be inferred on the evidence by applying the doctrine of res ipsa loquitur; (ii) whether the owner was vicariously liable because the driver acted in the course of employment and within the scope of authority; and (iii) whether the insurer's liability for a passenger's death was limited to the amount covered by the policy and the statutory insurance requirement.

Issue (i): whether the accident and the driver's negligence could be inferred on the evidence by applying the doctrine of res ipsa loquitur.

Analysis: The evidence showed that the car, on a straight and narrow road, went to the wrong side and struck a tree with great violence, causing severe damage and death of the occupants. There was no eye-witness, but the surrounding facts were unchallenged. In such circumstances the accident itself furnished a sufficient basis for inferring negligence, and the opposite party failed to establish inevitable accident or any non-negligent explanation.

Conclusion: Negligence was proved by inference and the doctrine of res ipsa loquitur applied in favour of the appellants.

Issue (ii): whether the owner was vicariously liable because the driver acted in the course of employment and within the scope of authority.

Analysis: The manager was driving the vehicle on the owner's business when he permitted the deceased to travel in it. Liability of the master depends on whether the servant's wrongful act was done in the course of employment or as a wrongful mode of doing an authorized act. On the facts found, the act of driving and giving the deceased a lift occurred during the business journey and fell within the course of employment, and the manager's position supported an inference of authority to act in that manner.

Conclusion: The owner was vicariously liable for the manager's negligent act.

Issue (iii): whether the insurer's liability for a passenger's death was limited to the amount covered by the policy and the statutory insurance requirement.

Analysis: The statutory policy requirement under the Motor Vehicles Act did not compel coverage for passengers who were not carried for hire or reward. The policy itself contained a passenger-risk endorsement for an additional premium and fixed a specific limit. On construction of the policy and the statutory scheme, the insurer's liability extended only to the amount expressly undertaken for passenger risk.

Conclusion: The insurer's liability was limited to the contractual cover of Rs. 15,000.

Final Conclusion: The award in favour of the claimants was restored with a reduced total compensation, the owner being liable for the balance and the insurer being liable only to the extent of the passenger cover.

Ratio Decidendi: Where a vehicle is being used on the owner's business and the servant's negligent act occurs in the course of that employment, the owner is vicariously liable; and passenger coverage under motor insurance depends on the statutory requirement and the express terms of the policy.
