A retired chief executive who breaches rules barring him or her from engaging in business or other activities to prevent any conflict of interest can be sued for breach of contract. Liu Pak-wai, member of the Independent Commission on the Remuneration Package and Post-office Arrangements for the Chief Executive, also warned that details of any breaches could be publicised by the government. Under the commission's recommendations, which were announced on Thursday, the chief executive should not work for property developers or franchisees within three years of retirement. Nor would the person be allowed to lobby on government matters, be employed by anyone suing the government, or bid for government land, contracts or franchises. Speaking on RTHK, Professor Liu addressed concerns that the government-appointed commission did not recommend any punishment for a former chief executive who breached the rules. He said the government can sue the person under such circumstances. This is because when the chief executive is sworn into office, he or she would be asked to sign an agreement about the rules which will form part of the contract. If the person breaches such rules after retirement, the government can take legal action. Professor Liu also said the government can publicise details of any application from the former chief executive which infringes the rules. He said such moves would serve as deterrence. 'The mechanism will be very transparent,' Professor Liu said. The commission also reviewed the salaries for the chief executive and recommended a monthly $90,000 pay increase for the next term of the chief executive in 2007, a move to turn various other benefits into cash form.
