Questione giuridica chiave
Whether the appellants had standing to challenge the refusal of intervention in the secret-lifting proceedings.
Decisione estratta
Yes. As beneficiaries of the lawyer's professional secrecy, they were directly affected and had a legally protected interest.
Motivazione estratta
Art. 89(1) LTF applies because lifting the secrecy concerns their personal sphere and the protection of their rights; refusal to admit them violated Art. 111(1) LTF.
