" 4. It is vehemently contended by Mr. P. Rama Rao, learned counsel appearing for the appellants, that no autopsy was conducted over the dead body of the deceased to arrive at the cause of death. It may be remembered that the deceased died during the course of medical treatment after about 25 days after the accident and he succumbed to the injuries. As already stated, Exh. A-10, the in-patient discharge ticket of the Hyderabad Nursing Home, where the deceased was undergoing treatment at the time of his death, shows that due to cardio-respiratory failure the deceased had died which is a consequence and secondary to head injury. The head injury was sustained by the deceased at the time of the accident. It is not a case under Section 302, Indian Penal Code, wherein the conducting of post-mortem examination to know the cause of death may be necessary. In this case, the cause of death is known from the documentary evidence, especially Exh. A-10 and also from the evidence of PW 2. The evidence of PW 2 is convincing. In the light of both oral and documentary evidence available in this case, the failure to conduct post-mortem examination over the dead body of the deceased cannot be taken as a circumstance against the claimants, who are claiming compensation for the death of the deceased.
