Eastern China Housing Developer Ordered to Refund 1200 Yuan Water Meter Fee as Unjust Enrichment

Case Overview
A civil lawsuit in Eastern China addressed whether a housing developer’s collection of a 1200 yuan water meter fee from homebuyers constituted unjust enrichment. The court found in favor of the plaintiffs, ordering the developer to return the fee plus interest. The case also examined the statute of limitations defense raised by the defendant.

Case Background and Facts
The plaintiffs, Mr. Cai and Mr. Cai, purchased an apartment from Zhejiang Economic Housing Development and Construction Company in 2003. At the time of property delivery, the defendant charged them 1200 yuan under the label “water meter collection fee.” In June 2010, the plaintiffs learned from neighbors that other homeowners had filed lawsuits seeking refunds of this same fee. After inquiring with property management, they discovered the 1200 yuan charge was allegedly an improper collection by the developer. The plaintiffs subsequently demanded a refund, which the defendant refused, leading to the lawsuit.

Court Proceedings and Evidence
The case was accepted by the court on December 21, 2010, and a public hearing was held on January 18, 2011. The plaintiffs presented several pieces of evidence, including the商品房买卖合同 (commercial housing sales contract), the property ownership certificate, the invoice showing the 1200 yuan payment, and a prior court judgment from a similar case that had ruled such fees were unjust enrichment. The defendant submitted engineering drawings, a price approval document from the Zhejiang Provincial Price Bureau, design change orders, completion drawings, cost verification reports, and cost calculation sheets to argue that the water meter expense was legitimate and not included in the original approved sales price.

Court Findings and Judgment
The court identified two main issues. First, it determined that the water meter was an essential infrastructure component for normal property use. The developer had a contractual obligation to provide this infrastructure. Since the sales contract contained no special agreement about separate charges for water supply facilities, the court held that the purchase price already covered such costs. The Zhejiang Provincial Price Bureau had also previously confirmed that the developer’s separate collection of 1200 yuan per household violated pricing regulations and constituted a disguised price increase.

Second, regarding the statute of limitations, the court applied the rule that the limitation period for unjust enrichment claims begins when the injured party knows or should know about the unjust enrichment and the responsible party. The defendant failed to prove the plaintiffs knew or should have known the fee was improper at the time of payment in 2003. The court accepted the plaintiffs’ claim that they only learned of the unjust enrichment in 2010 when notices about related cases were posted in their community. Therefore, the lawsuit filed in December 2010 was within the statutory period.

The court ordered the defendant to refund the 1200 yuan unjust enrichment fee and pay interest at an annual rate of 5.76 percent from April 21, 2003, until the date of actual payment. The defendant was also ordered to bear the court costs.

Key Legal Principles
The court applied the principle of unjust enrichment under Article 92 of the General Principles of Civil Law, which states that one who obtains benefits without legal basis and causes loss to another must return those benefits. The court also referenced Article 131 of the Supreme Peoples Court’s Opinions on Implementing the General Principles of Civil Law, which addresses the calculation of interest on unjustly obtained funds. Additionally, the court relied on Article 8 of the Supreme Peoples Courts Provisions on Statutes of Limitations in Civil Cases, which clarifies when the limitation period begins for unjust enrichment claims.

Practical Insights
This case demonstrates that homebuyers may challenge improper fees collected by developers, even years after the transaction. The burden of proof on the statute of limitations defense rests with the party asserting it. Homebuyers should be aware that government pricing authorities may provide official determinations that can support claims of improper charges. Developers must ensure that any fees collected beyond the contract price have a clear legal or contractual basis.
