JUSTICE PERALTA:

The fact that the notice of hearing was published in a newspaper of general circulation and notice thereof was served upon the State will not change the nature of the proceedings taken. A reading of Sections 4 and 5, Rule 108 of the Rules of Court shows that the Rules mandate two sets of notices to different potential oppositors: one given to the persons named in the petition and another given to other persons who are not named in the petition but nonetheless may be considered interested or affected parties. Summons must, therefore, be served not for the purpose of vesting the courts with jurisdiction but to comply with the requirements of fair play and due process to afford the person concerned the opportunity to protect his interest if he so chooses.

While there may be cases where the Court held that the failure to implead and notify the affected or interested parties may be cured by the publication of the notice of hearing, earnest efforts were made by petitioners in bringing to court all possible interested parties. Such failure was likewise excused where the interested parties themselves initiated the corrections proceedings; when there is no actual or presumptive awareness of the existence of the interested parties; or when a party is inadvertently left out.

          It is clear from the foregoing discussion that when a petition for cancellation or correction of an entry in the civil register involves substantial and controversial alterations, including those on citizenship, legitimacy of paternity or filiation, or legitimacy of marriage, a strict compliance with the requirements of Rule 108 of the Rules of Court is mandated. If the entries in the civil register could be corrected or changed through mere summary proceedings and not through appropriate action wherein all parties who may be affected by the entries are notified or represented, the door to fraud or other mischief would be set open, the consequence of which might be detrimental and far reaching.
