Eastern China Property Developer Ordered to Refund 1200 Yuan Water Meter Fee Plus Interest for Unjust Enrichment

Eastern China Property Developer Ordered to Refund 1200 Yuan Water Meter Fee Plus Interest for Unjust Enrichment

Case Overview
A homeowner in Eastern China successfully sued a property developer for unjust enrichment, recovering a 1200 yuan water meter fee charged at property handover in 2003. The court ruled the fee was improperly collected outside the agreed sale price, ordering repayment with interest at 5.76% per annum. The developer’s defense based on statute of limitations was rejected.

Case Background and Facts
The plaintiff, Mr. Lu, purchased an affordable housing unit from Zhejiang Economic Housing Development and Construction Company in 2003. During the property handover process in April 2003, the developer charged Mr. Lu 1200 yuan under the label “water meter fee collection.” The developer issued a special invoice for sale of immovable property. Mr. Lu later obtained the property title certificate for his unit in the San Tang Lan Yuan residential complex.

In 2010, Mr. Lu learned from other homeowners in his community that a group of residents had filed lawsuits seeking refunds of this same charge. After inquiring with property management, he discovered the 1200 yuan fee was being challenged as unjust enrichment. The developer refused to return the money, prompting Mr. Lu to file suit in December 2010 seeking return of the 1200 yuan plus interest of 501.12 yuan calculated from April 16, 2003 to July 15, 2010.

The developer argued that the claim was time-barred by the two-year statute of limitations, as the fee was paid seven years earlier. The developer also contended the charge was legitimate, explaining that after the provincial pricing bureau approved the sale price in December 2001, the company modified the design to install smart centralized meter reading systems to comply with municipal policies. This design change increased costs by over 1300 yuan per unit, and the 1200 yuan charge was passed to installers and the water company.

Court Proceedings and Evidence
Mr. Lu presented four pieces of evidence: the commercial housing purchase contract proving his purchase, the property certificate showing ownership, the invoice documenting the 1200 yuan water meter fee collection, and a prior appellate court judgment from 2010 that classified similar charges as unjust enrichment.

The developer submitted six exhibits: construction drawings showing the original design did not include smart water meters, the pricing approval document from December 2001, a design change order from December 2001 adding smart meters,竣工 drawings confirming the change, an engineering final account audit report with agreements and invoices showing actual cost of 1318.89 yuan per unit, and a calculation sheet establishing the 1200 yuan fee basis.

Both parties challenged the relevance of each other’s evidence. The court accepted all evidence as authentic since neither side disputed authenticity, but carefully weighed relevance in its analysis.

Court Findings and Judgment
The court identified two main issues: whether the developer’s collection of the 1200 yuan constituted unjust enrichment, and whether the claim was time-barred.

On the first issue, the court held that water supply facilities are essential infrastructure for normal property use. A real estate developer’s contractual duty includes ensuring complete basic infrastructure. The purchase contract contained no special agreement requiring buyers to bear separate water facility costs beyond the sale price. The court found the sale price already included water supply equipment costs. Furthermore, the provincial pricing bureau’s 2008 response letter confirmed the developer’s charge improperly raised the affordable housing price beyond approved levels. Therefore, the developer’s collection was unjust enrichment.

On the statute of limitations issue, the court applied the Supreme Peoples Court regulation stating that the limitation period for unjust enrichment claims begins when the party knows or should know of the unjust enrichment fact and the obligated party. The developer failed to prove Mr. Lu knew or should have known the fee was improper when it was charged in 2003. The court accepted Mr. Lu’s claim that he only learned of the unjust enrichment in 2010 when prior case notices were posted in the community. The December 2010 lawsuit was timely.

The court ordered the developer to return 1200 yuan within ten days of judgment effectiveness, plus interest at 5.76% per annum from April 17, 2003 until payment date. Litigation costs of 50 yuan, reduced to 25 yuan, were borne by the developer.

Key Legal Principles
The case established that charges collected outside an agreed contract price for essential infrastructure may constitute unjust enrichment under Article 92 of the General Principles of Civil Law. The burden of proving the plaintiff knew or should have known of unjust enrichment for statute of limitations purposes falls on the defendant. Design changes and cost increases after price approval do not automatically justify passing costs to buyers without contractual agreement.

Practical Insights
Homeowners should carefully review all charges imposed at property handover against their purchase contract terms. Regulatory pricing approvals for affordable housing establish maximum prices that developers cannot exceed through additional fees. Buyers who discover potentially improper charges years later may still recover if they can show they only recently learned of the unjust enrichment. Prior similar judgments in the same development can provide strong evidence for individual claims.
