Legal analysis: If the false accusation is true, it does not constitute a crime of extortion; if criminal detention has been taken, a lawyer can be entrusted for defense. False accusations and extortion require evidence. If it is a false accusation, the evidence will have no effect. To prove a false accusation, you only need to overturn the evidence presented by the plaintiff. After the criminal suspect is interrogated for the first time by the investigative agency or from the date when compulsory measures are taken, a criminal suspect may hire a lawyer to provide him with legal advice, appeals and accusations. If a criminal suspect is arrested, the hired lawyer can apply for release on bail pending trial. In cases involving state secrets, the criminal suspect's hiring of a lawyer must be approved by the investigative agency.
Legal basis: Article 11 of the Criminal Procedure Law of the People's Republic of China. The hearing of cases by the People's Court shall be conducted in public, unless otherwise provided in this Law. The defendant has the right to obtain a defense, and the People's Court has the obligation to ensure that the defendant obtains a defense.
