7. Mr. Mahanta, learned counsel for the appellant submits that nature of injuries sustained by the claimant – respondent No. 1 is not of permanent in nature and there is no medical certificate to that effect. Mr. Mahanta further submits that the P.W.2, who had given the certificate, is not an Orthopedic Surgeon and as such, assessing disability at 30% and also assessing loss of earning at 40%, are not in accordance with law. Mr. Mahanta referring to Exhibit – 4, the certificate of Doctor, submits that nowhere in the certificate it is stated that the injury got by the claimant is permanent in nature. Mr. Mahanta also submits that there was no servant and employer relationship between the respondent No.1 and 2, and though the respondent No. 2, the owner of the vehicle filed the written statement stating that the claimant – respondent No. 1 was his servant and he used to pay a sum of Rs. 3,000/- per month to him, is not established as he did not enter into the witness box. Mr. Mahanta also submits that awarding interest @ 12% is illegal at the relevant point of time the rate of interest was below than the same and the factor, which is required to be taken into account in assessing the compensation was not correct and as such, the impugned judgment and order is illegal and therefore, it is contended to set it aside.
