Mate AIPA can challenge a possible LH CR all they like. What you don't understand, is that a genuine redundancy as defined by Fair Work is when a persons job doesn't need to be done by ANYONE. So if the redundant jobs are LH jobs then that is where the CR's will be made if at all. AIPA can't force the company to apply CR across the board simply because the company cannot legally do that . All AIPA can do is ask for a RIN and maybe more VR's to be offered across the pilot group and not just LH.
In so far as your anticipated LWOP get out of gaol card is concerned all I can say is best of luck.
