How is it to be determined that a vendor is a high-risk vendor? What procedures are in place to challenge such a determination? I noticed that one can take an appeal to the High Court. I may be misreading this but it seems the Minister can offer information to the High Court to justify his or her decision and require that this information not be provided to a party to the appeal. Although the Minister can tell a judge the reasons for determining a vendor is high risk and give information to back up that assertion, can the Minister ask the judge not to give the information to the other side in the appeal to allow it to challenge it?
