The unfortunately reality is that Glen will not win from here. They will grind you down until you suffer a major mental health injury and then once you are institutionalized or worse passed away they will forget you even existed.
I have read every post on this thread. I know how much you have lost and suffered, but you will not win against CASA - they can already 'prove' to the AAT that you are a vexatious complainant.
Its time to cut your losses and get on with your life. Martyring yourself to a bunch of anonymous posters on the internet doesnt make sense.
