(2) The presiding judge announces the court session and summons the parties to appear in court to find out the names, ages, nationalities, native places, places of birth, educational level, occupations and addresses of the parties. The date when the people's procuratorate received the copy of the indictment and the date when it received the incidental civil action, etc. (3) The presiding judge announces the source of the case, the cause of action and whether the trial is held in public, and announces the reasons for not holding the trial in public. (4) The presiding judge announces the list of collegiate bench members, clerks, public prosecutors, defenders, agents ad litem, expert witnesses and translators, and informs the parties, legal representatives, defenders and agents ad litem of their legal rights in court proceedings, including: the parties and legal representatives have the right to apply for the withdrawal of collegiate bench members, clerks, public prosecutors, experts and translators; The defendant has the right to defend himself and entrust others to defend him according to law; The parties and defenders may apply to the presiding judge for questioning witnesses and experts, or directly ask questions of witnesses and experts with the permission of the presiding judge.

With the permission of the presiding judge, the parties, defenders and agents ad litem may express their opinions and debate with each other on the facts of the case and relevant evidence. After the court debate, the defendant has the right to make a final statement. (5) The presiding judge shall separately ask the parties and the legal representative whether to apply for withdrawal. If a party, legal applicant or public prosecutor who appears in court to support public prosecution withdraws, if the collegial panel considers that it meets the legal circumstances, it shall be handled in accordance with the relevant provisions of the Criminal Procedure Law; If it is considered that it does not meet the statutory circumstances, it shall be rejected in court and the trial shall continue.
