I doubt the court will do anything more than courts around the country have done with fire districts and police districts. It is a simple matter of there is no free ride.  You can not demand free services when your neighbors are paying for it.  When a fire department serving a service district does not save the house of someone out side the service district courts have ruled in favor of those departments. I suspect the same will be true should the police services for Girdwood ever make it to court.
