determination of income, the said heads have to be quantified. Any quantification must have a reasonable foundation. There can be no dispute over the fact that price index, fall in bank interest, escalation of rates in many a field have to be noticed. The court cannot remain oblivious to the same. There has been a thumb rule in this aspect. Otherwise, there will be extreme difficulty in determination of the same and unless the thumb rule is applied, there will be immense variation lacking any kind of consistency as a consequence of which, the orders passed by the tribunals and courts are likely to be unguided. Therefore, we think it seemly to fix reasonable sums. It seems to us that reasonable figures on conventional heads, namely, loss of estate, loss of consortium and funeral expenses should be Rs. 15,000/-, Rs. 40,000/- and Rs. 15,000/- respectively. The principle of revisiting the said heads is an acceptable principle. But the revisit should not be fact-centric or quantum-centric. We think that it would be condign that the amount that we have quantified should be enhanced on percentage basis in every three years and the enhancement should be at the rate of 10% in a span of three years. We are disposed to hold so because that will bring in consistency in respect of those heads.” .
