Legal analysis: Yes, private prosecutors in criminal proceedings cannot apply to the court for investigation and evidence collection. Article 195 of the Supreme People's Court's Interpretation on Several Issues Concerning Execution stipulates that after the people's court accepts a case of private prosecution, if the parties cannot obtain or provide relevant evidence due to objective reasons, the people's court may, if it deems it necessary, obtain evidence from the people's court.
Legal basis: Article 170 of the Criminal Procedure Law of People's Republic of China (PRC). When examining a case, the people's procuratorate shall interrogate the criminal suspect, listen to the opinions of the defender, the victim and his agent ad litem, and put them on record. If defenders, victims and their agents ad litem put forward written opinions, they shall attach a volume.
