A complaint is lodged over his funding of court challenge Lawmaker Albert Cheng King-hon faces a police investigation after a complaint over his involvement in the legal challenge to the Link Reit listing. The complaint was made yesterday by solicitor Andrew Lam Ping-cheong, who was accompanied by supporters Alex Tsui Ka-kit - a former deputy director of operations with the Independent Commission Against Corruption - and activist Lew Mon-hung. Mr Lam claims that Mr Cheng violated Hong Kong's common law by financing a judicial review of the Link real estate investment trust by two elderly residents of public housing estates. According to media reports, their legal costs came to $500,000. Mr Lam, a former senior ICAC investigator, claims Mr Cheng's action 'amounts to an offence of common law', specifically of 'maintenance'. Maintenance refers to unlawfully 'assisting in civil suits or quarrels of others' to the disturbance of common rights with 'other than charitable motives'. 'I don't see any charitable motive here,' Mr Lam said. 'As both plaintiffs have secured public housing residences and there is no likely chance of either of them being kicked out onto the streets, I feel this is already unlawful.' The offence is punishable by a fine or imprisonment. Mr Cheng said: 'On the one hand, I respect people's legal right. But on the other hand, I feel this is just part of a concerted campaign against me by my critics. It creates a lot of nuisance for me.' Mr Lam denied there was an ulterior motive to his call for an investigation, stressing he was acting independently. He said he had expected the government to investigate the matter but decided to go it alone after no action was taken. 'I personally feel this law should be repealed,' Mr Lam said. 'But since we have this common law, we need to investigate whether what Mr Cheng has done is unlawful. That's the least we can do. I have an obligation to alert people and the police to it.' He said he would help the police in any way but did not expect to be involved in the investigation. 'After all, I did not subscribe to any Link shares,' he said. 'I just want to take this matter to the investigation stage. After that, it is in the prosecutors' and courts' hands.' Mr Cheng has been the target of recent public protests and newspaper advertisements condemning his alleged role as the mastermind behind the reit legal challenge.
