1 The accused, the private claimant and the other persons involved in the proceedings may appoint a legal agent to safeguard their interests.
2 The parties may appoint two or more persons as legal agent provided this does not unreasonably delay the proceedings. In such a case, they must designate one agent as the principal agent, who is authorised to carry out acts of representation before the criminal justice authorities and whose domicile is deemed to be the sole address for service.
3 The legal agent may act for two or more persons involved in the proceedings, subject to the restrictions laid down by law and in their professional code of practice.
4 The parties may appoint any person who has the capacity to act, is of unblemished reputation and is trustworthy; the restrictions of the law governing the legal profession are reserved.
5 The defence of the accused is reserved to lawyers who are authorised under the Lawyers Act of 23 June 200041 to represent parties in court; the foregoing is subject to derogating cantonal provisions on the defence in proceedings relating to contraventions.
