Key legal question
Whether the terrace's operation after 22:00 had to be restricted under federal noise protection law.
Extracted holding
Yes. The terrace caused sensitive neighborhood noise, and limiting operation to 22:00, including cleaning and tidying, was lawful and proportionate.
Extracted reasoning
The terrace was an existing fixed installation, but its night-time behavior noise and tableware noise exceeded the tolerance threshold for the residential area. The court held that the only suitable measure was limiting operating hours, especially to protect the sensitive sleep phase after 22:00.
