Court Overturns Ruling in 7.6 Million Yuan Industrial Equipment Installation Dispute Over Flawed Expert Evidence

CASE OVERVIEW

An appellate court in Northern China reversed a trial court judgment in a contract dispute involving claims for 7.6 million yuan in damages. The case concerned responsibility for defects in industrial dust collection equipment at a cement production facility. The court found the trial court improperly relied on a forensic expert report that was obtained through procedurally flawed means and failed to meet basic evidentiary standards.

CASE BACKGROUND AND FACTS

In January 2007, Zhang Jiajie Ju Ri Cement Co Ltd entered into a sales contract with China Building Materials Beijing Environmental Protection Engineering Development Co Ltd to purchase five industrial dust collection units. The contract included a quality guarantee clause covering defects in design and manufacturing. In April 2007, the cement company signed a separate construction contract with Nanjing Kai Sheng Cement Mechanical and Electrical Equipment Installation Co Ltd to install the purchased equipment at a cement production line.

Both contracts were performed. The equipment supplier delivered the units, and the installation company completed the installation. After the equipment began operating, the cement company reported multiple problems including incomplete contact between the rotary kiln tire and support rollers, and malfunctions in the electrostatic precipitators and bag filters. The equipment supplier performed two major repairs, but the issues persisted.

In March 2009, representatives from all three companies met at the cement plant to discuss the problems. The equipment supplier claimed the primary cause was improper installation. The installation company argued the equipment had inherent defects. The parties could not agree on responsibility.

COURT PROCEEDINGS AND EVIDENCE

The cement company filed suit in August 2009 seeking 7.6 million yuan in damages. During the proceedings, the cement company withdrew the damages claim but requested an order requiring the installation company to repair the equipment to meet contractual specifications.

Both the cement company and the installation company applied for forensic examination. The trial court, without consulting the parties, appointed the National Building Materials Industry Building Machinery Product Quality Supervision and Inspection Testing Center to conduct the examination. The testing center issued a report in March 2010 concluding that most quality problems were installation-related, and that the rotary kiln issue was entirely an installation problem.

The trial court relied on this report to find the installation company liable and ordered it to complete repairs within three months. The installation company appealed.

COURT FINDINGS AND JUDGMENT

The appellate court identified two critical procedural errors in the trial court proceedings.

First, the trial court violated the Supreme Peoples Court regulations on civil evidence. The regulations require that when both parties apply for expert examination, the court must first allow the parties to jointly select an expert. Only if the parties cannot agree may the court appoint one. In this case, the trial court directly appointed the testing center without convening the parties to attempt agreement.

Second, the expert report itself failed to meet evidentiary requirements. The report did not include any documentation of the expert qualifications or professional certifications of the individuals who performed the examination. The trial court also failed to require the expert to appear in court for questioning by the parties, as required by law.

The appellate court emphasized that these procedural defects were not minor technicalities. The expert report was the central piece of evidence in the case. Without a properly obtained and admissible expert report, the factual basis for the trial courts judgment collapsed.

The appellate court vacated the trial court judgment and remanded the case for a new trial.

KEY LEGAL PRINCIPLES

Expert evidence in Chinese civil litigation must follow strict procedural rules. The court must give the parties an opportunity to agree on an expert before appointing one. The expert report must include proof of the experts qualifications. The expert must be available to testify in court and answer questions from the parties and the court. A judgment based on an expert report that fails to meet these requirements is subject to reversal.

PRACTICAL INSIGHTS

This case illustrates the critical importance of proper expert evidence procedures in commercial litigation. Parties should ensure they participate actively in the expert selection process. If the court proceeds without proper consultation, the affected party should object on the record. When challenging an expert report, focus on procedural violations and lack of qualification documentation. The appellate courts willingness to reverse demonstrates that procedural protections for expert evidence are not empty formalities.
