“6. Section 110-AA was inserted in the Motor Vehicles Act, 1939, by Amending Act 56 of 1969. The said section is applicable only where the death or bodily injury caused to a person gives rise to a valid claim for compensation under the Motor Vehicles Act, 1939, as well as a claim for compensation under Workmen’s Compensation Act, 1923. The said section prohibits the applicants from making double recovery of compensation by invoking both the Acts. If the application for compensation made before the Motor Accidents Claims Tribunal is rejected on the ground that the deceased himself was negligently driving the tractor in question it can hardly be said that the death of the deceased gave rise to a valid claim for compensation under the Motor Vehicles Act, 1939. If the claim for compensation made under Motor Vehicles Act could not be entertained by the Claims Tribunal for want of valid cause of action or for want of proof in respect of negligence of the driver causing the accident as alleged, section 110-AA of Motor Vehicles Act, 1939, can never be applied so as to bar the claim for compensation under Workmen’s Compensation Act, 1923. Even if the deceased was himself negligently driving the tractor leading to the accident in question, the claim for compensation under Workmen’s Compensation Act, 1923, may be still maintainable against the employer concerned or against the insurance company if the deceased died as a result of an accident which took place during the course of employment of the deceased. Section 3, Workmen’s Compensation Act provides for statutory liability of the employer to pay compensation to the workman or his dependants if the death or personal injury is caused by accident arising out of and in the course of employment of the workman concerned. The criterion to be applied for determination of an application for compensation under the Workmen’s Compensation Act, 1923, is somewhat different from the criterion to be applied for determination of a claim for compensation under section 110A of Motor Vehicles Act, 1939. * * *
