Questione giuridica chiave
Whether there was a sufficient legal basis for south approaches and related noise impacts
Decisione estratta
The basis lies in the federal aviation legislation, the airport operating regulations regime, and the expropriation and environmental law framework; the claim that the SIL process or cantonal planning alone barred the changes was rejected.
Motivazione estratta
The court held that Art. 36c and 36d LFG, together with Art. 25 VIL, govern approach procedures and their approval. Enteignungsrecht and environmental law allow, in principle, compensable or protectable interference from airport noise. Cantonal plans do not per se preclude a new operating concept pending coordination in the planning process.
