Questione giuridica chiave
Whether a valid Zurich choice-of-court agreement under Art. 23 LugÜ existed
Decisione estratta
No valid jurisdiction agreement for Zurich was proven.
Motivazione estratta
The correspondence and contract documents did not establish a clear mutual agreement; the signed EULA still contained exclusive German jurisdiction, and the later materials did not prove that both sides accepted a Zurich clause in the required form.
