A judge turned down a request by fung shui master Tony Chan Chun-chuen to let his experts take part in tests on a document ruled to be a forged will of the late Nina Wang Kung Yu-sum, calling the idea of two groups of experts conducting experiments in the investigation together 'nonsense'. Chan and the Chinachem Charitable Foundation have been fighting for Wang's multibillion-dollar fortune, with Chan claiming she gave it to him in a 2006 will out of love, and Chinachem saying she left it to the charity in a 2002 will. A court ruled in Chinachem's favour in February, saying Chan forged the 2006 will. Police are investigating Chan, and conducting tests on the 2006 document. In the latest instalment of the battle of the wills yesterday, Chan asked the Court of Appeal to grant him permission to participate in the tests. However, Mr Justice Anthony Rogers dismissed his application. '[Chan] wants his experts to be able to look over the shoulders and conduct experiments at the same time as the police. I don't consider the protocol workable,' he said.
