That’d be the ‘ruling’ that says:
A user of aviation rulings should also be aware that a ruling is only a statement of CASA’s policy. It is not a restatement of the law. Accordingly, while rulings are drafted to be consistent with the law referred to in the ruling as understood by CASA from time to time, they cannot displace any inconsistent legal requirements.
In short, it’s just someone’s opinion, just like yours and mine.
Anyway, it’s all academic because the new, simple, outcomes-based classification of operations scheme will come into effect in 1998.
