That suit isn't going anywhere.

Did you read the ALPA motion to dismiss and the response? There were 60 separate mentions of case law from the appellate to the Supreme Court level where the suit itself does not even meet the requirements to be heard. Like the Complainants failing to enjoin the company in the suit, even though the company was one of the parties of the ISL process. Essentially they are suing the wrong party. The company administers the ISL and agreed to implement it. They can't be forced to change it or stop using it because they aren't being sued.

I respect everyone's right to fairness under the law, but "I wanted to be higher on the ISL" isn't a valid reason to file a lawsuit. And there are plenty UAL 1996 hires and later that aren't thrilled with the results of the SLI but none of them sued to change it.
