Well, if you look at the code, to which you are subject as a member of Parliament, you see that it says, “to avoid real or apparent conflicts of interests”. This is a very well known concept in law that judges apply all the time to determine whether the parties before them are conflicted or not.
Strangely enough, that wording is not used in the act. The act has only a definition of what a conflict of interest is; it does not use the words “real or apparent conflicts”. You could put those in there anywhere—they have a jurisprudential meaning—and people would know how to apply them and how to advise you on whether something was not a conflict but rather an apparent conflict, and a rational man on the street looking at that would say, “This isn't right.”
