我国检察院在现行民事法领域中具有违背法理的功能定位,并在维护公益方面存在着功能缺失。通过考察国外检察机关维护公益之功能界定,本文认为在民事法领域,检察院应当通过提起或参与民事公益诉讼来维护公益,作为公益维护者其在民事诉讼中是形式当事人或诉讼参与人。 The procuratorate of our country has the function orientation contrary to jurisprudence in the field of current civil law and there is a lack of function in safeguarding public welfare. By examining the definition of the function of public procuratorial organs in safeguarding public welfare, this paper argues that in the field of civil law, procuratorates should safeguard public welfare by bringing or participating in civil commonweal litigation. As public welfare defenders, they are formal parties or litigants in civil litigation.
