A "neutral BK judge", ruled that Lorenzo had the legal right to void its labor contracts as part of a bankruptcy filing. I suppose the pilots could have said, "well, I don't like, but its legal." No they fought back and went on strike and called the people who went to work there "scabs" even though, it was all "legal." In the particular case of US/AWA the debate on legal responsibilities isn't over and will be heard shortly before the 9th Cir. That aside, fighting for right, in the face of legal is nothing new.
Dred Scott comes to mind, ruled on not by the majority but the ultimate neutral in this country. It didn't stand and a war, along with a courageous president proclaiming emancipation finally tumble the concept that someone could be property.
