Case Digest (G.R. No. 162571)
Expanded Legal Reasoning Model

Facts:

  • Background of Parties and Relationship
    • In 1992, petitioner Arnel L. Agustin courted Fe Angela Prollamante; they entered into an intimate, on‐and‐off relationship from 1993 to 1998.
    • Fe allegedly conceived Martin on her 34th birthday (November 10, 1999) and gave birth to him out of wedlock on August 11, 2000 at Capitol Medical Hospital, with a birth certificate purportedly signed by Arnel.
  • Post-Birth Events and Dispute
    • Arnel initially paid prenatal and hospital expenses but then refused to support Martin, suggested adoption, and denied paternity; an incident occurred on January 19, 2001 when Arnel’s van door struck Fe’s leg.
    • In July 2001, Fe was diagnosed with leukemia and commenced chemotherapy; on March 5, 2002, Fe and Martin filed a support complaint (RTC, Quezon City Branch 106, Civil Case No. Q-02-46301).
  • Trial Court Proceedings
    • Arnel’s Defenses and Motions
      • Denied he sired Martin, alleging affair ended in 1998 and had secret lover; claimed signature on birth certificate and CTC were forged; invoked right against self-incrimination.
      • Moved to dismiss complaint for lack of cause of action, asserting unrecognized illegitimate child cannot claim support; filed criminal and civil petitions to cancel his alleged acknowledgment and proved forgery via PNP laboratory certification.
    • Orders of Lower Courts
      • On February 5, 2003, RTC denied Arnel’s motion to dismiss and, under Rule 28 of the Rules of Court, directed DNA paternity testing at respondents’ expense.
      • On January 28, 2004, the Court of Appeals (CA) in CA-G.R. SP No. 80961 affirmed both the trial court’s resolution denying dismissal and its order for DNA testing; a March 8, 2004 CA resolution likewise affirmed.

Issues:

  • Conversion of Action
    • Whether the order for DNA testing and the CA’s decision effectively converted the complaint for support into a petition for recognition of paternity.
    • Whether, under the Civil Code (Arts. 265, 283) and Rules of Court (Rule 105, Sec. 1), an unrecognized illegitimate child must first file a separate recognition suit before claiming support.
  • Constitutionality of DNA Testing
    • Whether ordering compulsory DNA paternity testing violates petitioner’s right against self-incrimination (Art. III, Secs. 12 and 17, 1987 Constitution).
    • Whether such testing infringes his right to privacy under the Constitution.
