Whether Article 147 CPP applied to auditions conducted in separate proceedings against A, B, and C.
The accused had no party status in the separate proceedings against A and C, so Article 147 CPP did not grant him or his lawyer a right to attend those auditions. The audition of B was not a violation because the defense was present.
The right to participate in evidence-taking applies to the parties in the same proceedings, not in separate proceedings against another accused. The cantonal court's contrary reasoning was contradictory and legally unsustainable.
