Probably in talking to the person complained against, it might come to light. They might not even realize they had contravened another section. Just looking at the act I might see some other thing that ought to be dealt with. It could happen in a number of ways. It doesn't happen that frequently, but it does happen from time to time.
You were also concerned about reporting on the examination. The rule is I must release a report on an examination in all cases, but in the case of an examination I have initiated myself, I can discontinue that without issuing a report. If I discontinue one that was requested, I must issue a report.
I think there's quite a rational reason for that because if I self-initiate something that nobody has requested, and I find there's nothing to it, then why would I put out something and suggest where there's smoke there's fire? Usually those things come to me from the media or from private citizens. In some cases I would not release a report, but those are the only cases. If a member or a senator requested it, a report would come out.
