Coming to the quantum of compensation, the material on record establish that the deceased was doing the work of centring contractor during the said period. The evidence of PW.1 would show that the deceased was earning Rs.15,000/- per month. To prove the same the claimants examined PWs.3 and 4 and also got marked Exs.A7 to A12. Ex.A7 is the certificate issued by Ch.Marthanda Rao and company, certifying that the deceased worked as a centring contractor in their company. Ex.A8 is the identity card, wherein it was mentioned that he is a member of the Twin Cities Centring Contractors Association. Ex.A10 is the letter addressed by the Accounts department of the Associated Realtors Private Limited to the deceased relating to payment of Rs.10,000/- as token advance. Ex.A11 is the quotation. Ex.A12 is the form No.16-A. Thus, the aforesaid documentary evidence mainly Exs.A7, A8, A10 and A12 coupled with the evidence of PWs.3 and 4 clearly prove that the deceased was doing the job of Centring contractor during his life time. It is to be noted that as a contractor there would not be any fixed income. Therefore, it is not possible to arrive at any fixed figure and it all depends upon the nature of centring which he does. Hence, some guess work needs to be adopted for fixing the income of the deceased. It is true that there is no evidence available on record to show the income of the deceased. But, having regard to the facts and circumstances of the case and the documentary evidence available on record, the finding of the Tribunal in fixing the income of the deceased at Rs.15,000/- per month cannot be said to be on higher side.
