Kernrechtsfrage
Whether the civil judge is competent to hear an ownership-protection injunction against airport overflights and noise from a concessioned airport with expropriation powers.
Extrahierter Entscheid
Because the airport operates under a federal concession and expropriation powers, the affected owner must pursue claims before the expropriation authorities; the civil judge is not competent.
Extrahierte Begründung
For a concessioned airport, overflights and related immissions arising from the intended operation are covered by the expropriation regime. Private-law defensive remedies are displaced, and the expropriation judge decides both the scope of the right and compensation; this applies to direct overflights as well as indirect immissions.
