"10. The only challenge made in these appeals is regarding the correctness of the finding made by the Claims Tribunal in fixing negligence on the driver of the bus bearing Registration No.KA-38-A1, insured with the appellant. All the four witnesses have deposed that the accident has occurred due to the rash and negligent driving of the bus driver. Perusal of the oral testimony of PW3/Mrs.Sabastin Mary, the claimant in M.C.O.P.

In addition, they have also filed Ex.P8/Rough Sketch, reflecting the manner of the accident. As rightly pointed out by the Claims Tribunal that neither the contents of the FIR nor the details of the rough sketch/Ex.P8 had been contradicted by the appellant/insurance company by examining the
