BUSINESSMAN Lee Ming Tee and two of his companies are appealing against a decision refusing them leave for a judicial review to quash a decision of the Financial Secretary in appointing an inspector and are seeking a stay in the inspection of the group. Mr Lee, Allied Group and Allied Properties are seeking leave for judicial review to quash the decision of the Financial Secretary in establishing a ''steering committee'' and seeking a declaration that he or the inspector acted ultra vires. Counsel Warren Chan, appearing for Mr Lee, submitted in the Court of Appeal that the judge erred in failing to hold that in the light of the statutory duties laid upon the inspector it was unlawful that a steering committee comprising servants of the executive branch of the Government and of the regulatory authorities should be ''in regular contact'' with the inspector. Mr Chan maintained that the judge held wrongly that the inspector discussed only ''matters relating to the administration of the inspection''. He submitted that the steering committee was in regular contact with the inspector and discussed ''the way in which the investigations could proceed''. He said it was clear from this that the role of the steering committee was far more than ''the administration'' of the inspection. Mr Chan argued that the judge failed to consider the real risk that the inspector might unconsciously be influenced in the conclusions he reached because of the direction of the steering committee. He said the ultimate purpose of any investigation was to provide information on which to take action if the facts warranted it. Peter Graham for the Allied group will make his submission today and Adrian Huggins, QC, for the inspector will reply.
