Since the law suit is against the state, and as state school professors they are paid by the state and are employees of the state, it's somewhat reasonable to see a conflict of interest for them to testify when the defendant is their employer.
That said, it should be up to the lawyers and parties involved in the law suit to evaluate that conflict of interest. There was no reason for the school to interfere there.
