Kernrechtsfrage
Whether an accused person or appointed defence counsel has a right to attend the interrogation of a co-accused, other witnesses, or informed persons.
Extrahierter Entscheid
No such entitlement exists under the principle of separate interrogations; if confrontation rights are granted later, the parties' participation rights are respected.
Extrahierte Begründung
Art. 146(1) StPO establishes separated interrogations, so neither accused persons nor witnesses have a general right to be present at the interrogation of co-accuseds or other persons. A later granted confrontation opportunity cures the participation aspect under Art. 147(1) StPO.
