Neville Nobody,
Izzatso ---Not really, with all due respect I refer you to the Advance Airlines crash on runway (now) 34L at YSSY, and what the subsequent inquiry/legal action thought of the controller's actions, when the aircraft Captain said everything but "mayday".
A pedantic reliance on "the book" does not override a requirement for a proper exercise of professional expertise and judgment ---- and this applies in any field, not just aviation.
The "Nuremberg Defense" in not exactly a reliable defense.
Tootle pip !!
PS: Unfortunately, in particular when they find out otherwise the hard away, and very commonly in the Australian aviation community, many people believe your statement is an accurate description of the legal position.
