The applicant, Kwok Yuen Ho, brought a motion for an order requiring Staff of the Ontario Securities Commission to produce the working file of the investigator responsible for the insider trading investigation against him.
The applicant argued that the file was necessary to make full answer and defence, as the investigator would be a key witness at the hearing.
The Commission dismissed the motion, distinguishing between evidence obtained during an investigation (which must be disclosed) and materials created by an investigator (which need not be disclosed unless the investigator is giving expert opinion evidence).
As the investigator was only being called as a fact witness, the working file was deemed irrelevant and not subject to disclosure.
