73ganda - I have no opinion on what DJ did or didn't do. I stated that the test for a legal conviction is what is "reasonable" as determined by the Court.
DJ complied with his employers instructions and the regulations. Neither CASA or ATSB could show that what he did was unreasonable.
He thus demonstrated the existence of a gaping hole in CASA's regulatory strategy - that the regulations are strict of necessity to keep the public safe and that adherence to the letter guarantees a safe outcome.
