The person doesn't speak to the decision-maker. The persons who decide to put the person on the list in the first place comprise a committee of three: Transport Canada, CSIS, and the RCMP, at the senior level. They make the decision to put the person on the list. They will get a delegation from the Minister of Transport.
If the person goes through a reconsideration, the person doesn't speak to that committee. The applicant for a reconsideration speaks only to the expert adviser hired to listen to the case. This expert adviser in turn makes a recommendation to the minister to reconsider the decision, or not. That decision will be made and will have to be looked at again by the committee, given the new information.
