the Act or Rules or the policy conditions, it is not automatic that in every case the principle of contributory negligence is to be applied mechanically. As rightly observed in the other Division Bench decision, namely, M.Anandavalli Amma v. Arvind Eye Hospital, 2002 (3) L.W. 710, unless there is evidence to prove that the accident took place only because of such act that is taking/travelling more persons in a motor cycle which resulted in an accident, the owner of the other vehicle and its insurer will be liable to pay compensation. To put it clear, if the appellant-Transport Corporation is able to prove that it is because of the addition of one more (third person in the motor cycle instead of two), the accident occurred, the position would be different. In other words, unless the owner of the vehicle or the Insurance Company is able to prove that the accident took place only because of such act that is taking more persons than the prescribed number, the owner/Insurance Company will be liable to make good the loss/compensation. In the case on hand the materials placed before the Tribunal show that it was the bus driver who had gone to the other side of the road, hit the motor cycle thereby caused the accident. There is no evidence to show that the accident occurred because of travelling of three persons in the motor cycle. In the light of the above said conclusion, we reject the contra argument made by the learned counsel for the appellant."
