material supplied, but the plaintiff did not respond the complaint. The plaintiff was given one more opportunity to attend and rectify the quality as per letter dated 25.05.2006, but the plaintiff not acted upon. The plaintiff failed to keep up their promise. As such, the defendant-Corporation, procured additional 7.5 metric tons polythene sheets from open market for Rs.6,70,275/-. As such, non settlement of bills is directly linked to the supply of materials of higher thickness by the plaintiff. Though the plaintiff undertook to supply 7.5 metric tons of polythene sheets as extra material, but not responded to the request of the Corporation. Due to the less supply, the rubber plantations could not be rapped, due to which the corporation suffered the loss of production of natural rubber in a sum of Rs.1,35,81,045/-. As the transaction is of a commercial nature, the supplier is liable to make good the loss. Therefore, the plaintiff is liable to pay Rs.6,70,275/- to the defendants towards the expenditure incurred in purchasing the extra polythene sheets. The plaintiff started issuing the legal notices and approached this Court. As such, the defendants-Corporation is left with no other option than filing a counter claim against the plaintiff and prayed for dismissing the suit and to allow the counter claim by directing the plaintiff to pay Rs.6,70,275/- with interest at rate of 18% p.a. from the date of suit till the date of payment.
