Forky they dont even bother with that these days it would seem.
Regardless of radar, GPS etc, it will still come down to a CASA opinion.
Once they decide you "did it" all the evidence to the contrary will
be ignored and they will gnaw on you like a dog with a bone.
Who has the money to fight them in the AAT or in a "Proper" court?,
Even if you win they can always get an FOI to say you were drunk six months ago at a meeting and pull your medical, or because you got a tad angry when the "perfectly reasonable" FOI called you a liar to your face insist you undergo psychological evaluation, of course with a shrink of their choice.
You simply cannot beat them, better to just pay the fine, let the FOI get a notch on his gun to add to his promotion tally and go on flying.
