The law provides that:
Article 23 of the Criminal Procedure Law: When necessary, the people's court at a higher level may try criminal cases of first instance under the jurisdiction of the people's court at a lower level; A criminal case of first instance that the people's court at a lower level considers that the case is serious and complicated and needs to be tried by the people's court at a higher level may request to be transferred to the people's court at a higher level for trial.
Article 24 A criminal case shall be under the jurisdiction of the people's court of the place where the crime was committed. If it is more appropriate to have the case tried by the people's court of the defendant's domicile, it may also be under the jurisdiction of the people's court of the defendant's domicile.
Article 25 A case over which several people's courts at the same level have jurisdiction shall be tried by the people's court that accepted it first. When necessary, it may be transferred to the people's court of the place where the main crime is committed for trial.
Article 26 A people's court at a higher level may designate a people's court at a lower level to try a case with unclear jurisdiction, or it may designate a people's court at a lower level to transfer the case to another people's court for trial.
