In our system, as in any other, it may be a concern if people cannot get written opinions on various matters that are subject to interpretation. In the area in which I work at the moment, we do provide opinions in writing on controversial issues. For me, this is a way of ensuring that the rules are enforced in a consistent and foreseeable way. First and foremost, we must ensure that people understand rules and their import properly, and that the rules are stated clearly.
