This appeal considered whether a municipal notice of reserve that blocked construction at a federally approved antenna site was constitutionally valid.
The majority held the notice’s pith and substance was the siting of radiocommunication infrastructure, an exclusive federal matter, making it ultra vires.
The Court also held the measure significantly impaired the federal core protected by interjurisdictional immunity.
The appeal was allowed and the notice was unconstitutional and inapplicable to the appellant.
