Kehar Singh's land it was 875 mtrs. The Reference Court reasoned that the pipes had been laid in the year 1970-71 and the evidence given by the witness was that the pipes would last 25 years and they would require to be re-laid later. The Reference Court, therefore, reasoned that the normal life span would be upto the year 1995-96. Considering the fact that the pipes had been laid in the year 1970-71 and taking note of the fact that Section 4 notification had been issued in the year 1989, the Reference Court held that the expenses per mtr. in the year 1991, if it were to be assessed at 140/- per mtr., there has to be a scaling down of this rate for the life of the pipes which had already gone past 3/4<sup>th</sup> of its life span. It, therefore, took the value of the cost after deduction at 30/- per mtr. and held that for 569 mtrs, the value could have been 17,070/-. It made a further deduction of 4/5<sup>th</sup> on the ground that the pipes are already run up a fairly long span. Similarly for the property of Kehar Singh, the Tribunal assessed as compensation of 26,250/- and made a further depreciation of 4/5th for determining a compensation of ` 5250/-. The manner of determination of compensation, in my view, is erroneous.
