People vs. Umanito

The Supreme Court may order DNA testing in a pending criminal case under the New Rules on DNA Evidence to determine paternity, and a probability of paternity of 99.9% or higher creates a disputable presumption of paternity that, if uncontradicted, supports conviction; furthermore, filing a motion to withdraw an appeal constitutes accession to the lower courts' rulings.

The case originated from a rape charge filed against Rufino Umanito for allegedly raping AAA in 1989, which resulted in the birth of a child (BBB) on April 5, 1990. The accused denied the charge and raised the defense of alibi, claiming that while he had courted the victim, they were not sweethearts and had no sexual relations. The incongruent assertions between the prosecution and defense, particularly regarding the nature of their relationship and the possibility of consensual intercourse, prompted the Supreme Court to seek scientific evidence to resolve the factual dispute.

• Rufino Umanito was charged with raping AAA in 1989, which allegedly resulted in her pregnancy and the birth of BBB on April 5, 1990, nine months after the incident.
• The RTC of Bauang, La Union, Branch 67 found Umanito guilty beyond reasonable doubt of rape and sentenced him to suffer the penalty of reclusion perpetua and to indemnify the victim in the sum of P50,000.00.
• On appeal, the Court of Appeals affirmed the judgment of the trial court, prompting Umanito to file an appeal with the Supreme Court.
• In its Resolution dated October 26, 2007, the Supreme Court noted incongruent assertions between the prosecution and defense, particularly regarding whether the accused and victim had a consensual relationship.
• The Court ordered DNA testing to determine whether Umanito is the biological father of BBB, noting that if he is not the father, this may cast reasonable doubt on his guilt.
• DNA samples (buccal swabs and blood) were extracted from AAA, BBB, and Umanito at the New Bilibid Prisons on February 8, 2008, witnessed by Judge Ferdinand A. Fe, the prosecutor, defense counsel, and Deputy Court Administrator Reuben Dela Cruz.
• NBI Forensic Chemist Mary Ann Aranas conducted the DNA analysis using the Powerplex 16 System, examining 15 loci for paternity matching purposes.
• The DNA analysis revealed a complete match in all fifteen (15) loci tested between the alleles of Umanito and BBB, establishing a 99.9999% probability of paternity.
• The accused did not object to the admission of the DNA evidence nor present evidence to controvert the presumption of paternity established by the results.
• Umanito filed a Motion to Withdraw Appeal dated February 16, 2009, which the Supreme Court treated as accession to the lower courts' rulings.

• N/A (The text does not explicitly detail specific legal arguments raised by the Office of the Solicitor General or the People of the Philippines in the Supreme Court proceedings, though the prosecution consistently maintained the guilt of the accused and presented evidence including the DNA test results.)

• Raised the defense of alibi and denied engaging in sexual relations with the complainant.
• Asserted that while he had courted AAA, they were not sweethearts, thereby discounting the possibility of consensual sexual intercourse.
• Filed a Motion to Withdraw Appeal dated February 16, 2009, effectively acceding to the rulings of the RTC and Court of Appeals finding him guilty.

• Procedural Issues:
  • Whether the Supreme Court should grant the accused's Motion to Withdraw Appeal.
  • Whether the DNA evidence was properly admitted and handled in accordance with the chain of custody requirements under the New Rules on DNA Evidence.
• Substantive Issues:
  • Whether the DNA testing results showing 99.9999% probability of paternity establish a disputable presumption of paternity under Section 6 of A.M. No. 06-11-5-SC.
  • Whether the uncontradicted DNA evidence supports the conviction of the accused for rape.

• Procedural:
  • The Motion to Withdraw Appeal is granted. By filing such motion, Umanito is deemed to have acceded to the rulings of the RTC and the Court of Appeals finding him guilty of rape and sentencing him to reclusion perpetua and indemnification of P50,000.00.
  • The DNA evidence was properly admitted as the accused did not interpose any objection to the admission of Exhibits "A" and "B" (DNA reports), and the chain of custody was properly established through the testimony of NBI Forensic Chemist Mary Ann Aranas.
• Substantive:
  • Under Section 6 of the New Rules on DNA Evidence, the DNA test result showing 99.9999% probability of paternity creates a disputable presumption of paternity.
  • This presumption was not contradicted or overcome by other evidence, as the accused failed to present evidence to rebut the DNA findings.
  • The DNA results conform with the conclusions of the lower courts and corroborate the victim's testimony that Umanito fathered the child born nine months after the alleged rape, thereby affirming his guilt.

• New Rules on DNA Evidence (A.M. No. 06-11-5-SC) — The first application of these rules in a pending case before the Supreme Court, allowing for DNA testing to be ordered to determine paternity in a criminal case where such evidence would be determinative of the resolution of the appeal.
• Disputable Presumption of Paternity — Under Section 6 of the DNA Rules, if the value of the Probability of Paternity is 99.9% or higher, there shall be a disputable presumption of paternity which may be contradicted and overcome by other evidence under Rule 131, Section 3 of the Rules of Court.
• Chain of Custody in DNA Evidence — The requirement that biological samples be collected by a neutral third party, properly identified at collection, protected with tamper tape, and handled with thorough documentation at each stage to ensure integrity and prevent contamination, as mandated by Sections 4(a), (b), (c), and (e) of the DNA Rules.

• "With the advance in genetics and the availability of new technology, it can now be determined with reasonable certainty whether appellant is the father of AAA's child." — The Court's rationale for ordering DNA testing to resolve factual disputes in the rape case.
• "If he is not, his acquittal may be ordained. We have pronounced that if it can be conclusively determined that the accused did not sire the alleged victim's child, this may cast the shadow of reasonable doubt and allow his acquittal on this basis." — Explaining the potential exculpatory value of DNA evidence in rape cases where paternity is at issue.
• "If the value of the Probability of Paternity is 99.9% or higher, there shall be a disputable presumption of paternity." — Citing Section 6 of A.M. No. 06-11-5-SC regarding the statutory presumption established by high probability DNA results.
• "By filing such motion, Umanito is deemed to have acceded to the rulings of the RTC and the Court of Appeals finding him guilty of the crime of rape, and sentencing him to suffer the penalty of reclusion perpetua and the indemnification of the private complainant in the sum of P50,000.00." — Establishing the legal effect of a motion to withdraw an appeal in criminal cases.

• A.M. No. 06-11-5-SC (New Rules on DNA Evidence), Sections 4(a), (b), (c), (e), and 6 — Governs the admissibility, evaluation, and standards for DNA testing, including the requirement for proper chain of custody and the creation of a disputable presumption of paternity when DNA testing shows a probability of 99.9% or higher.
• Rule 131, Section 3, Rules of Court — Defines disputable presumptions as satisfactory if uncontradicted but may be contradicted and overcome by other evidence, applied to the presumption of paternity under the DNA Rules.
