The composition of the panel is determined by the Minister of Environment and Climate Change, from the roster, of which two would come from the petroleum board members who are on the roster. The balance would be chosen from the minister's roster, and that would be composed of the five people who are on the panel.
The inner workings as to how the panel develops its report and how it comes to its conclusions is the panel's responsibility, and it's not statutorily defined anywhere in the act.
