Homebuyer Wins Refund of 1,200 Yuan Water Meter Fee in Unjust Enrichment Case

Homebuyer Wins Refund of 1,200 Yuan Water Meter Fee in Unjust Enrichment Case

Case Overview

A homeowner in Eastern China successfully sued a real estate developer for unjust enrichment, recovering a 1,200 yuan water meter fee charged at the time of property delivery. The court ruled that the developer improperly collected the fee outside the agreed sales price, and the homeowner’s claim was not barred by the statute of limitations. The judgment also awarded interest on the improperly collected amount.

Case Background and Facts

In 2002, Mr. Wu, the plaintiff, entered into an economic housing purchase contract with Zhejiang Economic Housing Development and Construction Co., Ltd., the defendant. The property was located in the Santang Lanyuan residential complex in Eastern China. On April 20, 2003, during the handover process, the defendant collected 1,200 yuan from Mr. Wu under the label “water meter fee on behalf.” Mr. Wu paid the amount and received an invoice.

In 2010, Mr. Wu learned from other homeowners in his community that the same fee had been challenged in court. A prior judgment had determined that the developer’s collection of this fee constituted unjust enrichment. Mr. Wu then demanded a refund from the developer, but the developer refused. On December 21, 2010, Mr. Wu filed a lawsuit seeking the return of 1,200 yuan plus interest of 501.12 yuan, calculated from April 17, 2003, to July 16, 2010, at an annual rate of 5.76 percent.

The developer argued that the claim was time-barred, as the fee was collected in 2003 and the lawsuit was filed seven years later. The developer also contended that the fee was justified because the original construction design did not include the smart water metering system, which was later added to comply with municipal policies. The developer claimed the actual cost per household was over 1,300 yuan, and the 1,200 yuan fee was passed on to the installation contractor and water company, meaning the developer did not profit.

Court Proceedings and Evidence

Both parties presented evidence at trial. Mr. Wu submitted the purchase contract, property ownership certificate, the invoice for the 1,200 yuan fee, and a prior appellate court judgment from Eastern China that had ruled similar charges constituted unjust enrichment.

The developer submitted construction drawings showing the original design did not include smart water meters, a price approval document from the Zhejiang Provincial Price Bureau dated December 11, 2001, an engineering change order from December 25, 2001, adding the smart meters, final竣工 drawings, a cost verification report showing actual costs of 1,318.89 yuan per household, and a calculation table supporting the 1,200 yuan fee.

The court accepted the authenticity of all evidence but noted that the developer’s evidence did not establish a legal basis for charging the fee outside the contract price.

Court Findings and Judgment

The court identified two key issues. First, whether the developer’s collection of the 1,200 yuan fee constituted unjust enrichment. The court held that water supply facilities are essential for normal residential use and are part of a developer’s contractual obligation. Since the purchase contract did not include a special provision requiring the buyer to bear additional water meter costs, the sales price was deemed to include all infrastructure costs. The Zhejiang Provincial Price Bureau had also determined that the fee was an improper charge that effectively raised the housing price. The court therefore found the developer’s collection was unjust enrichment.

Second, the court addressed the statute of limitations defense. Citing the Supreme Peoples Court’s interpretation on limitation periods, the court noted that the limitation period for unjust enrichment claims begins when the claimant knows or should know of the unjust enrichment and the responsible party. The developer failed to prove that Mr. Wu knew or should have known the fee was improper at the time of payment. The court accepted Mr. Wu’s claim that he only became aware of the unjust enrichment in 2010 when information about prior cases was posted in the community. Therefore, the lawsuit filed in December 2010 was timely.

The court ordered the developer to refund the 1,200 yuan and pay interest at 5.76 percent per annum from April 21, 2003, until the date of payment. The developer was also ordered to bear the court costs.

Key Legal Principles

The case applied the principle of unjust enrichment under Article 92 of the General Principles of the Civil Law. A party who obtains benefits without a legal basis and causes loss to another must return those benefits. The court also applied the rule that the limitation period for unjust enrichment claims runs from the date the claimant discovers or should discover the unjust enrichment and the identity of the beneficiary.

Practical Insights

This case demonstrates that developers cannot charge homebuyers for infrastructure costs that are implied in the purchase price, unless the contract expressly allows such charges. Homebuyers who discover improper fees years after purchase may still recover those amounts if they were not aware of the improper nature of the charge. The court’s ruling also highlights that a prior price bureau determination can serve as strong evidence of unlawful pricing practices. Buyers should keep all payment receipts and invoices, as these documents are critical for proving the amount and nature of disputed charges.
