How about -
they wouldn't clear me for the approach because they were saturated so I did the illegal high dive
Sounds to me like he wasn't cleared for an approach so just did it anyway, illegally.
late approach clearance, now above G/S, having to do a little "dirty" dive to save the approach. Still well within common sense.
That I can live with but is it illegal? No, didn't think so.
Of course, I wouldn't have to try and interpret things if people were clear what they meant in the first place.
