The U.S. Supreme Court has ruled that the FCC can enforce "reasonable" approval times for cell tower site applications, meaning that local governments can't stall applications. The FCC has wanted 90 day and 150 day deadlines for approval of cell tower site applications. As I read the article, it does not mean all tower site applications have to be approved by local government, but the local government has to approve or reject the application within the FCC "reasonable time" definition.
