A woman has failed in an attempt to sue her husband's friends after he drowned in a public toilet following a booze-sodden banquet. The man, surnamed Song, was invited to a friend's house for dinner in February last year. He left after drinking heavily and was found dead the next morning in the pit of a public bathroom, apparently after falling in. Song's wife filed a lawsuit alleging that two friends of her late husband were responsible for his death as they knew he was drunk but did not accompany him home. She demanded 31,863 yuan in compensation. But the court rejected the lawsuit, saying that as an adult with the 'capacity for civil conduct', Song alone was responsible for his alcohol consumption and subsequent death. 'I agreed with the court's decision,' said lawyer Li Haibo, of the Beijing Yuecheng law firm. 'His friends are not his legal guardians and have no obligation to ensure his safety.' Zhao Yongxuan, a lawyer with Beijing firm Li Wen, said that while the verdict was not incorrect, there was still room for some punitive damages. 'The two men should be required to pay some money to serve as a moral warning to the public,' he said. Li Haibo, who successfully sued the Beijing city government two years ago after a client's car was damaged when he drove into an uncovered manhole, said the number of liability lawsuits being filed on the mainland were increasing. 'These types of lawsuits happen for two reasons. One is because people blow small issues out of proportion. The other is that people have started to become aware of their legal rights, though this doesn't mean that they necessarily have solid legal ground to stand on,' he said. Mr Li put forward two measures that would prevent the number of frivolous cases from getting out of hand. 'We need to increase the general public's legal knowledge and make the costs of lawsuits more prohibitive to dissuade all but those with serious claims from suing,' he said.
