Putting aside the issue of whether Jamison is able to raise the funds to close a deal with the NHL (big IF, IMO), I don't think today's hearing had much impact on anything. The judge denied the GWI's request for relief. The CoG stipulated well before the hearing that the ordinance was not passed by emergency clause, so that issue cannot be a surprise to the NHL or Jamison. Since the CoG stipulated to that point, the GWI didn't really "win" anything. Their motion simply mischaracterized the CoG's action.
At this point, the citizens can seek to have the matter referred for a vote in Fall. I think it is likely they will be able to get in on the ballot. What will that mean in terms of Jamison and the NHL closing? I don't think it will have any effect assuming Jamison can come up with the money. However, Jamison's deal with the NHL is probably conditioned upon him having an arena to play in, and if the CoG deal falls through, I wouldn't be surprised if Jamison's deal doesn't include some kind of a relocation clause so he can move the team.
