The "Da Vinci" event reappears! British furniture is falling into the door of fraud
Not long ago, the "Da Vinci" furniture origin of the turmoil has not subsided. Recently, a newly married couple in Jinan, on the grounds of fraud, sold the furniture to their furniture store and the furniture city to the court, saying that they purchased The British furniture worth tens of thousands of yuan was once told to be made by "100% European imported eucalyptus", but in actual use, it found that low-quality inferior plates, such as pine. A few days ago, the North Park Court of the Tianqiao District Court of Jinan City opened a court in the furniture city involved in the case and publicly heard the case. When the couple filled the expensive "imported" furniture to invite friends to find a guest, they found "catty". In January this year, Wang Fang (a pseudonym), who lives in Tianqiao District of Jinan, married, and deliberately selected furniture in a large furniture city in Beiyuan, Tianqiao District. In the mall's furniture store, after the sales staff's high recommendation, Wang Fang and his wife saw a combination of furniture worth 44,800 yuan - including more than ten independent furniture such as double bed, sofa, wardrobe, bar, etc. The combination set inside is designed in English style. At that time, the salesperson introduced the furniture as "100% European imported eucalyptus", and eucalyptus is a high-grade solid wood, which is very rare. After hearing these introductions, Wang Fang was very excited. After negotiating with her husband, Wang Fang paid the payment and let the furniture merchants transport the British furniture to the home. The "Da Vinci" incident was unsettled. The furniture in Britain was caught in a fraudulent door. After the wedding, the couple invited friends to visit the house. Everyone praised the couple's decoration style. But they heard the furniture material as "100% European import." At the time of the coffin, a friend who knew the line raised doubts and pointed out that the furniture was actually expensive beech, and there were cheap materials such as pine inside. Wang Fang, who did not pay attention to these details beforehand, rushed to check with everyone. As a result, it was found that the so-called 100% European imported beech furniture, the back panel of the bed board and the wardrobe, can be clearly seen as not made of eucalyptus, but at a low price. And the material is poor pine board. The consumer rights protection couple feels that they are being fooled to pick up legal weapons. After discovering that there is a problem with the furniture materials purchased, Wang Fang and his wife, who are being fooled, will sell the furniture to their furniture store and the furniture city where they are located. A rights lawsuit. The North Park Court of the Tianqiao District Court of Jinan accepted the case and opened a court in the furniture city a few days ago to openly hear the case. In the court, both the plaintiff and the defendant did not show up, and all the lawyers came to respond. In the complaint, the plaintiff Wang Fang and his wife pointed out that the other furniture company was suspected of fraud. According to the plaintiff, according to the propaganda of the merchants at the time, the furniture should be made of pure eucalyptus. In order to prove this, the plaintiff also presented the purchase contract on the spot. In one of them, the material was “100% European imported eucalyptusâ€. . In the plaintiff's view, although the paragraph in the contract was written by Wang Fang, it was recognized by the defendant. However, in the process of responding to the lawsuit, the defendant furniture store made a different view. It believes that the part of the contract that states that “100% European imports of eucalyptus†is written in the main material column, which means that the main material of the furniture is eucalyptus, and the rest can be other materials. In an interview with the author, the defendant claimed that the furniture contained other materials, such as pine and camphor wood, in addition to eucalyptus. "Pinewood may be cheaper, and the price of camphor wood is actually more expensive than eucalyptus." The defendant furniture store said that the purpose of adding these materials is to meet the actual needs of the furniture. "The coffin is harder, the pine is softer, if it is a bed board, etc. The furniture industry still uses pine wood." The plaintiff of the controversy: All furniture should be the defendant of the coffin: the coffin is indeed 100% imported in the subsequent court debate stage, the original defendant both sides slap the sword, the focus of the debate continues on the "100% European import coffin furniture" contract. At the same time, the two sides also continually debated whether the term “100%†was modified by furniture or coffin. The plaintiff believes that the word “100%†is decorated with furniture, which means that the furniture should be 100% eucalyptus. The defendant furniture store believes that "100%" is decorated with eucalyptus, and eucalyptus is indeed 100% imported. In addition, during the trial, the defendant's furniture store also presented a list of tariffs, trying to prove that the coffin part of the furniture was actually imported through Europe and the United States. Under the auspices of the court, the two parties finally settled the furniture store to compensate the consumers for 10,000 yuan. Finally, under the auspices of the Beiyuan Court of the Tianqiao District Court, the original defendants of each term ended the settlement. This set of British furniture is still owned by the plaintiff. The defendant's furniture store compensates the plaintiff for 10,000 yuan, and the plaintiff's legal fee of 1,000 yuan is borne by the plaintiff. Liu Yuanlu, the judge of the North Park Court, who was in charge of the case, said that the case was rather peculiar that the original defendant wrote the “100% European import of eucalyptus†furniture into the furniture purchase contract, which also became a controversy. point. The case also reminded a lot of people who want to buy furniture and decorate the house. In the purchase contract, it is best to record the material and structure of the purchased furniture in detail, to prevent disputes in the future, if they can The details are marked in detail, and in the future, in the event of a dispute, it may be presented to the court as evidence to protect its rights and interests. This time, the Beiyuan court directly moved the case to the furniture city involved in the case, in order to let more people understand the process of the case, and pay more attention to the protection of their rights and interests.
