Eastern China Court of Appeal Rules on Payment Hinges on Energy Savings Test in 480,000 RMB Equipment Dispute

Case Overview

The Eastern China Court of Appeal upheld a lower court ruling in a dispute between an energy equipment supplier and a leather manufacturer over a 480,000 RMB heat exchanger. The court dismissed both the supplier’s claim for unpaid balance and the buyer’s counterclaim for contract rescission and damages, holding that neither party had met its burden of proof regarding the equipment’s energy-saving performance.

Case Background and Facts

In December 2007, a supplier of environmental protection equipment and a leather processing company entered into a contract for the sale and installation of a thermal counterflow heat exchanger. The total contract price was 550,000 RMB, later reduced to 480,000 RMB under a supplemental agreement. The buyer made an initial payment of 200,000 RMB. The contract provided that the equipment was expected to achieve energy savings of approximately 25 percent, with the final payment tied to actual performance.

The parties conducted joint sampling of the boiler system in December 2007 and January 2008. However, disputes arose over whether the equipment met the promised energy-saving standards. In December 2009, the parties signed a second supplemental agreement. This new agreement linked the remaining payment to specific energy savings thresholds: if savings were below 10 percent, no further payment was due; if savings reached 12 percent, the buyer would pay 150,000 RMB; if 15 percent, 200,000 RMB; and if 18 percent, 250,000 RMB. The agreement also introduced a new testing method and provided that if the parties disagreed on results, a qualified national authority would conduct testing.

The buyer never made any further payment, and no testing was ever performed under the 2009 supplemental agreement.

Court Proceedings and Evidence

The supplier filed a lawsuit seeking payment of 350,000 RMB plus interest. The buyer counterclaimed, seeking contract rescission, return of the 200,000 RMB deposit, and 100,000 RMB in damages for alleged boiler damage caused by the equipment. The buyer argued that the equipment not only failed to save energy but also caused boiler tube fouling, grate deformation, and scale blockage, forcing a boiler replacement in June 2008.

During trial, the supplier initially changed its claim to 250,000 RMB based on an assumed 18 percent savings rate, then reverted to its original claim. The supplier refused to apply for expert testing of the equipment’s energy performance, despite the court’s explicit instruction and a deadline notice. The buyer initially applied for a forensic examination of both energy efficiency and boiler damage but later withdrew its application. The court then issued a deadline notice requiring the supplier to apply for testing, but the supplier formally declined.

On appeal, the supplier submitted a 2008 test report from a provincial energy monitoring center. The court excluded this evidence because it predated the 2009 supplemental agreement and was therefore irrelevant to the payment obligations established by that agreement.

Court Findings and Judgment

The court held that both the original contract and the 2009 supplemental agreement were valid and binding. The supplemental agreement replaced the earlier testing results and created a new framework for determining the final payment based on energy savings. Under this agreement, the supplier bore the burden of proving that the equipment met the required energy-saving thresholds.

Because the supplier refused to permit independent testing, it failed to prove that the conditions for payment had been satisfied. The court therefore dismissed the supplier’s claim. The court also dismissed the buyer’s counterclaim, finding that the buyer had not provided sufficient evidence to prove that the equipment caused boiler damage or that the contract should be rescinded.

The appellate court affirmed the trial court’s decision in its entirety, rejecting both parties’ appeals.

Key Legal Principles

The court applied the fundamental principle that a party asserting a claim bears the burden of proof. The supplier could not demand payment without proving that the contractual conditions for payment had been met. The court also affirmed that a valid supplemental agreement supersedes prior testing arrangements and that courts will not treat a valid agreement as void simply because both parties failed to perform their obligations under it.

Practical Insights

This case illustrates the critical importance of clear performance metrics and testing protocols in equipment sales contracts. When payment is contingent on measurable results, the seller must be prepared to prove those results through agreed-upon testing methods. Refusing to participate in court-ordered expert examination can be fatal to a claim. Buyers should also note that alleging equipment defects requires concrete evidence, and unsubstantiated claims will not support a counterclaim for damages or contract rescission.
