You can't have an aviation law without exemptions. How else could CASA respond to political pressure - sorry, I mean produce the best safety outcomes based on its subjective opinions?
The exemptions always put the lie to the safety justification for the rule. Yes, I realise there are always a bunch of conditions and workarounds that purportedly achieve an equivalent level of safety. But if that's true, the exception should be built into the rule in the first place.
The primary aviation law in Australia is, in substance, the exemptions. CASA's primary regulatory activity is, in substance, granting exemptions.
