What is the difference beetwen official and non official rules?

Does non official mean, that it is not official when staff does not want to apply them and official would mean they need to apply rules?

If your staff does apply rules only when it fits to agenda and not applying when it does not fit to someone's agenda, then rules are being twisted by meanings and there is silence from staff.

Please explain me the meaning of unofficial rules and how is staff being instructed to apply them.
