Regarding the merit of the strike: if the judge rules that the changes made by BA are not contractual (that is what the court case is about) than a strike against those changes based on the current ballot proposition (that the changes are contractual and therefor BASSA should have been involved) is again illegal.
The ballot for strike action is
not about what actual changes have been made, whether contractual or not, it is about the
imposition of changes.
So even if the changes are judged to be non-contractual Bassa will ballot regardless because changes
have been made without their agreement. (as I understand it!!)
