Sorry Bengal, but Hollis Harris pretty much slammed the door on any case you claim to have.
The essence of his testimony was that regardless of any position taken by Air Canada Pilots on Implementation of Picher:

he would never have agreed to a pilot seniority merger where the operations themselves were not being merged;

it was his personal view that any seniority merger which puts any regional pilot ahead of any mainline pilot would be unacceptably unfair; and

therefore, he opposed and would not have agreed to implement any seniority merger between Air Canada and regional pilots under the Picher award.
Also unions only uphold seniority lists within the same company. Air Canada and the regionals were separate companies. According to your logic all Star Alliance pilots should be under one seniority list.
Your beef could very well be with CALPA and not the Air Canada pilots. CALPA was the organization that let you down. When the Air Canada MEC refused to advance the Picher list at contract talks, CALPA could have disciplined them according to CALPA policy. CALPA chose not to discipline the Air Canada pilots. If you are sueing anyone it should be CALPA for not following its own policy.
In the end Bengal, you will have at least another 2 years to stew over this matter and give yourself more ulcers. For me? I sleep well at night knowing that I have earned my position and the perks that go with it. I also enjoy flying with your former First Officers that came to Air Canada through the front door.
We should know the final outcome in a couple of years (at the earliest). I am aware that your opinion will not change even after the Supreme Court makes its decision. I doubt that my opinion will change either. I will not debate the issue here further as I believe all that can be said, has been said. If you care to respond, I will give you the last word.
