If we want to be pedantic both "AND" and "OR" can be ambiguous, since the separation will almost always comprise of both horizontal and vertical components. Probably the best way would be to re-write the rule to state something like "maintain 200ft separation from other aircraft in all directions"
I admit that I may have missed the point that you were opening a seperate thread regarding the legal aspects of the way in which the rules are written. However I make no apologies for wanting to maintain the focus on the the subject of training and ensuring all pilots that we share the sky with know the rules and fly within them!

Subject: Re: [Aus-soaring] 200 feet separation rule The rule is not ambiguous. It states something quite different to what is intended. The use of the word AND states that we must have both a 200 ft horizontal as well as a 200ft vertical separation when in fact we are only required to have one or the other.. This list was not long ago discussing a court case from here in Victoria where a Gliding club (I think it was Mt Beauty Gliding Club) was held liable for full damages even though some badly written Victorian Legislation was intended to stop this from occurring. The judge seemed to know that the law was intended not to be taken in the way he interpreted it but it was written in way he interpreted it.. Maybe this has been overturned or the law changed since we last talked about it but if not, then due to this silly interpretation, all Victorian gliding clubs (and probably power planes) are liable to full damages in accidents in joy flights which return to the same field as they started from. That is, due to an interpretation of a journey having to go from one point to a different point. I can't remember the actual words from this court case but I'm sure someone on this list can post them to show how these things can have disastrous effects. To say this serves no purpose is not to understand how important these things can be. My email right from the first sentence made it clear that I was referring to possible problems with the law courts. I also changed the Subject as it was a change of subject.
