Kernrechtsfrage
Whether the civil courts had jurisdiction over an ownership-based action seeking to prevent airport overflights and emissions.
Extrahierter Entscheid
The complaint did not show a violation of constitutional property protection sufficient to establish civil-court jurisdiction; the issue belonged, if at all, to expropriation law under federal law.
Extrahierte Begründung
The Court held that claims arising from unavoidable, concession-based airport operations are generally displaced by expropriation compensation rules. The appellant's objections targeted the constitutionality of the expropriation regime, not the civil court's jurisdiction, and did not meet the strict pleading requirements.
