What does it mean that lawyers are not allowed to accuse criminal defendants in court?

This is the basic duty of defense lawyers.

As the adjudicator, the court judge is the organizer of the trial and controls the trial procedure. The procuratorate prosecuted on behalf of the state, accusing the defendant of criminal facts. The trial of criminal cases requires participants to perform their respective duties in order to achieve judicial justice and balance and mutual supervision and restriction. If the lawyer accuses the defendant, it will break the fairness and balance of this kind of justice, and the justice will lose its credibility and justice and fairness. Therefore, it is an internationally accepted judicial practice for defense lawyers not to accuse defendants.
