I have to correct myself, there is indeed a case where a judge sided with a union in an 1113 motion.

In looking at old Comair case files, I discovered that there were actually two 1113c motions against the FA's (Teamsters).

In the first one (April 2006), the judge found that the company had not bargained in good faith and sent them back to negotiate further.

In the second (July 2006), the judge found that Comair had done a better job and threw out the FA contract.
