Nina Wang has no reason to delay divulging the source of $1.5 billion she allegedly used to acquire a major share in a key Chinachem company, the Court of Appeal ruled yesterday. Ms Wang could face further inquiries about 'any ultimate' source of the money if the court-appointed administrators of Teddy Wang's multibillion-dollar estate deemed it necessary, Mr Justice Anthony Rogers said in a written judgment. The Chinachem chairwoman had complained of being too busy to answer a list of questions posed by the administrators, who are seeking to identify the assets of the missing tycoon. Together with Mr Justice Azizul Suffiad, the judge dismissed Ms Wang's attempt to delay compliance with a previous order by Deputy Judge Gerard Muttrie. She was also ordered to shoulder the costs of her appeal. Judge Muttrie, presiding at a closed-door hearing in the Court of First Instance on June 15, ordered the property tycoon to answer a list of questions posed by the administrators. In particular, Ms Wang was asked to give the source of $1.5 billion she was said to have used to acquire 15 million 'B' shares in Chime Corporation between August 23 and September 7, 1990.
