Maybe. But by just addressing the RLA, your response shows the flaw in his argument.While his characterization concerning the judge may be questionable, his observation on the self-help provisions of the RLA are accurate.
You don't need a law degree to read/understand the RLA.
More than just the RLA is at issue here. Bob is (and I suppose you are, too) totally ignoring the other relevant law in this dispute -- the Bankruptcy Code.
It is nice to have the luxury of only considering, addressing, and citing the law that supports your position and being able to hide behind one side of the story while totally ignoring the other side. However, a judge does not have that luxury.
Make no mistake: ultimately I agree a union has the right to strike (in a traditional form, or in the form of CHAOS) in this situation. But if you are trying to be legally or rhetorically persuasive, you don't help your position by only repeating one position over and over and not explaining why the other side's position is wrong.
If you want to convince anyone important (like a judge, for instance), you not only better know your argument inside and out, but you need to show you know your adversary's as well.
