Speaking to reporters later, Khir said his lawyers had served Ng the letter of demand last Friday at the parking lot.<br /><br />"I was criticised in the hall for something that I'm not guilty of. That is why I said he was biased," he said, adding that the Federal Constitution supported his claim that 'Dewan' referred only to the meeting hall.<br /><br />Khir also said Kinrara state rep Teresa Kok had served him a legal notice within the meeting hall last year but he did not complain to the speaker because he did not want to disrupt the proceedings.<br /><br />The former MB said he would consult his lawyer soon to explore the possibility of taking legal action against Teng.<br /><br />The letter of demand to Ng alleged that the DAP rep had defamed the Umno leader while making allegations pertaining to Khir's lavish mansion in Shah Alam.
