LG.. Judge will ask Rosen to clarify the viability of the GSA as it stands.. If he says it is dead, then no appeal is necessary and she certifies her order of denail of the Plan, therefore allowing new negotiations and maybe a new POR by other parties.
If he says it is active, then she certifies the appeal and he maintains his POR rights. He can stop the appeal by declaring the GSA dead. In My Opinion, He will say it is dead and we move on to other issues. I could be wrong, never under estimate a SHARK!
