The injuction was granted because the judge felt that Mesa must have a compelling case...it's that simple. They stand a very realistic chance of winning the case. Doesn't mean they will, but there is a chance. No judge is going to refrain from banging the gavel out of pity for the other side. Will Mesa or Delta win? Who knows. Mesa probably has a better case than most would suspect...What I would be asking:

1.) Which judge is hearing this next case...is he/she the same judge who granted the injunction? What is their track record in such cases?

2.) What are the previous outcomes for cases like this where a business, such as Mesa in this case, won the injunction and went on to win the case?

It's a significant case because it has far-ranging implications for both parties. For Mesa, continuing revenue stream and trying to stay alive while money in this country is scarce. For Delta, this will set a precedent and will dictate how they'll continue to restructure their regional feed. In this sense, the final decision will also directly affect other regional airlines besides Mesa.
