It is not necessary for the court to begin or continue the substantive hearing of the case when all the litigation claims of the procuratorial in stitutions have been fully realized. However, even if the procuratorate loses the interests of asking the defendant to correct the illegal administrative act or perform the legal duties according to law, the procuratorate may still have the interest to ask the court to confirm the illegal administrative act. In order to relieve the public interests that have been damaged or threatened in time, public interest litigation rules should guide the defendant to correct the illegal acts or to perform the legal duties according to law as soon as possible. Therefore, the rules should be designed differently according to the time when the defendant corrects the illegal act or perform the legal duties according to law.
