Questione giuridica chiave
Whether the investigating judge had to be recused for alleged bias arising from search and seizure measures and denial of access to the file.
Decisione estratta
No objective circumstances showed bias or an appearance of bias; the recusal request was properly rejected.
Motivazione estratta
Under Art. 29(1) of the Constitution, recusal requires objectively ascertainable circumstances creating a doubt as to impartiality. Procedural errors do not suffice unless particularly serious or repeated. The challenged acts were available under cantonal procedure and could have been attacked by complaint; they did not show malice or partiality.
