Usually, the minister issues a notice and order for security reasons, such as a threat to security or an immediate threat to security. The legislation allows the company to go to court and appeal. During the appeal process, it is important that the notice and order be in effect until the appeal is heard, since it is a case of threat to security.
As the bill stands right now, if there were an appeal, we would have to remove the notice and order of the minister, who is actually trying to solve a security problem.
