The Commissioner varied the decision of the Department to refuse the appellant's request. He found that the Department was justified in refusing access to MATS information on names of passengers and time spent on board aircraft by officials, on the basis that this information does not fall within the definition of "environmental information" contained in the AIE Regulations. He found that the Department was not justified in refusing to provide access to MATS information on dates of travel, destinations of travel, flight durations, the number of passengers travelling, and the names of office holders and departments availing of the service, as this information falls within paragraph (c) of the definition of environmental information. The Commissioner also found that information on dates and destinations of travel is environmental information under paragraph (b) of the definition. The Commissioner stated that, unless his decision is appealed to the High Court, the Department should make a new decision on the appellant's request under the AIE Regulations.
