Judges love procedure and precedent it seems. Establish your procedure and stick to the precedents in the issues and you should be good. The NFL has been swinging wildly based on public perception for about 5 years now. A tightening of the CBA is needed for both sides honestly. I think if a good number of people believe that Brady and the Pats cheated, yet again, and get to go free it hurts the integrity of the game to some extent. Shore up your process NFL and try and come up with a set of rules that covers minimums and maximums for most things like you've done with the JDA.
Judges are the last bastion of protecting the process, which includes everything all the way up to the constitution.
Although "due process" can be a nebulous term, it really comes into play with everything under the law -- including matters that are not statutory in nature, like arbitration or administrative matters.
The Judge wrote it in his ruling. Arbitration, particularly collectively bargained arbitration, is not something that courts step in and get a hand in the jar ordinarily because it isn't statutory. But when you bungle it up so badly that you've essentially committed a harm to a party or abridged what are otherwise considered inalienable rights under the XIV Amendment, the court's going to slap you down.
I'm sending my resume to Goodell. Haha.
