If I recall correctly, the federal court basically said its too complex (or words to that effect) to force reinstatement when Qantas lost initially.
So, presumably that will stand, but one would think now that they have run out of appeals, compensation and fines would be imposed.
If so it must be substantial as a deterrent and not just allow them to have a long term win and shrug it off as "a cost of doing business."
The cost of lost wages for 1700 staff and compensation for lost future earnings would be substantial if was to be applied. Let alone any fines.
