There has been a lot of speculation on this site about what the judge means between the lines of his memo, how he thinks, what he will be angry about, and even what he will do about it, by people who really have no clue. (We ALL have no clue, but some are claiming they do)
The fact that courts don't like to hear arbitration cases is interesting to consider but irrelevant to this case. Courts don't like to let murderers go, but when due process is violated they do it any way. In other words, whether the standard is high or not doesn't speak to whether the standard is met.
I think that Brady would have a wonderful case about guilt or innocence, but that isn't at issue here.
I think Brady has an iron clad, slam dunk case that the arbitration of the decision was not fair, reasonable, or consistent with the CBA, the law of shop, or the labor laws in this country.
