Rules on Criminal Procedure
Section 5. Who must prosecute criminal actions. - All criminal actions commenced by a complaint or information shall be prosecuted under the direction and control of the prosecutor. However, in Municipal Trial Courts or Municipal Circuit Trial Courts when the prosecutor assigned thereto or to the case is not available, the offended party, any peace officer, or public officer charged with the enforcement of the law violated may prosecute the case. This authority cease upon actual intervention of the prosecutor or upon elevation of the case to the Regional Trial Court. (This Section was repealed by A.M. No. 02-2-07-SC effective May 1, 2002)
The crimes of adultery and concubinage shall not be prosecuted except upon a complaint filed by the offended spouse. The offended party cannot institute criminal prosecution without including the guilty parties, if both alive, nor, in any case, if the offended party has consented to the offense or pardoned the offenders.
The offenses of seduction, abduction and acts of lasciviousness shall not be prosecuted except upon a complaint filed by the offended party or her parents, grandparents or guardian, nor, in any case, if the offender has been expressly pardoned by any of them. If the offended party dies or becomes incapacitated before she can file the complaint, and she has no known parents, grandparents or guardian, the State shall initiate the criminal action in her behalf.
The offended party, even if a minor, has the right to initiate the prosecution of the offenses of seduction, abduction and acts of lasciviousness independently of her parents, grandparents, or guardian, unless she is incompetent or incapable of doing so. Where the offended party, who is a minor, fails to file the complaint, her parents, grandparents, or guardian may file the same. The right to file the action granted to parents, grandparents or guardian shall be exclusive of all other persons and shall be exercised successively in the order herein provided, except as stated in the preceding paragraph.
No criminal action for defamation which consists in the imputation of the offenses mentioned above shall be brought except at the instance of and upon complaint filed by the offended party. (5a)
The prosecution for violation of special laws shall be governed by the provisions thereof. (n)
