There can be situations in which information is relevant although not required for the ministers to prove the case or not required for the individual to be reasonably informed of the case. In such situations, for example, you may have an overall report on a variety of different subject matters, and only part of that report might include something that pertains to the person. In such situations, the rest of the report may not have anything to do with the case at hand, and so the provisions allow the minister to ask a judge to provide an exemption. So the judge would see everything. They could also exercise broad discretion to see if part of that report could be, for instance, held back. They can also communicate with the special advocates to the extent required so that they can make a determination and the special advocates can make a submission as to whether or not that exemption should be granted.
