I will just keep it simple.
Is there value to hearing this case?
In a word, no. If the court rules in favor of Inks, regional merger negotiations will continue. If they receive the proper support, the approved negotiations would prompt a Senate vote. If the court does not rule in favor of Inks, regional merger negotiations will continue. If it receives the proper support, the merger will occur.
The only reason to hear this case is political, since the only difference in outcome would be to have the Senate forced to approve the finalized merger. As such, the only difference would entail a difference in the composition of the Senate, a political process. It would take a great deal of judicial activism, thus, to grant cert, as the court would essentially be tacitly approving a politicization of the process by a party, who, in the classical sense of the term, lacks standing.
