Legal basis: Article 13 of the Code for Lawyers Handling Criminal Cases, the same lawyer shall not defend two or more criminal suspects and defendants in the same case, nor shall he defend two or more criminal suspects and defendants who are not involved in the same case but are related to the suspected crime. If the same law firm accepts the entrustment of two or more criminal suspects and defendants in the same case and appoints different lawyers as defenders, it must inform the clients and obtain their consent.
