In your instance, the code for the House of Commons has to look at what the principles are. They have to “fulfill their public duties with honesty and uphold the highest standards so as to avoid real or apparent conflicts of interests, and maintain and enhance public confidence and trust in the integrity of each member and in the House of Commons”.
The member would come, lay out the question, ask if it complies with subsection 2(b), which I just read out to you, and ask what the implications are, etc. We would give them advice and say it's up to them, but we would suggest they do A, B, C, or not D, or yes, you can do all of it, whatever the situation is. The member then proceeds as he or she sees fit.
