Kernrechtsfrage
Whether the horse stable with run-out and equipment shed could be retroactively authorized.
Extrahierter Entscheid
No. The structure lies largely within the watercourse area and does not qualify as an exception for new installations in that area; an after-the-fact permit is therefore excluded.
Extrahierte Begründung
Under the water protection rules, new installations in the watercourse area are generally prohibited. The stable serves only a private agricultural side activity and is not a public-interest, site-bound installation.
