All hypothetical of course, because nobody knows the facts...
Well, no. If a Summons has been served, the Summons and alleged facts must be a matter of public record. If that Summons was issued some years ago and the matter has not been settled by the Court, it should be a public concern.
If no Summons has been issued, the matter may have been handled internally to ATSB and CASA's satisfaction.
It is not a matter of "who dobbed them in". I'm sure the incident would be a reportable incident under the Transport Safety Investigation Act 2003 (TSI Act)?
