A MAN who has been declared mentally incompetent by a district court in the United States has filed a writ with the Supreme Court through his representative, suing a company for damages for personal injuries. Philip Higgins, on behalf of Kristan Phillips, contends that due to the negligence of Wong Ching Ho Company Ltd, Mr Phillips was poisoned after an incident in 1987. The action was brought following an order last year by a district court judge in Wyoming, declaring Mr Phillips, a former principal timpanist with the Hong Kong Philharmonic Orchestra, mentally incompetent. According to the claim, Wong Ching Ho had supplied pesticide, including diazinon, to a pest control operator, Initial Environment Services Ltd, formerly known as Exclusive. The operator then used it in the Academy for Performing Arts in Wan Chai, it is claimed. The claim alleges that as a result of negligence by Wong Ching Ho and action contrary to the Agricultural Pesticides Ordinance, Mr Phillips, who was 40 at the time, was poisoned after an incident on June 21, 1987.
