**People of the Philippines v. Rufino Umanito**
### Facts:
1. **Initial Trial and Conviction:**
– Rufino Umanito was charged with rape, and the Regional Trial Court (RTC) of Bauang, La Union, Branch 67 found him guilty beyond a reasonable doubt. He was sentenced to reclusion perpetua and ordered to indemnify the private complainant, AAA, in the sum of P50,000.00.
2. **Court of Appeals:**
– Umanito appealed to the Court of Appeals, which upheld the RTC’s decision.
3. **Supreme Court:**
– Umanito further appealed to the Supreme Court. The Supreme Court noticed conflicting assertions from both prosecution and defense, particularly concerning the nature of Umanito’s relationship with AAA and the defense of alibi raised by Umanito.
4. **Resolution to Apply DNA Evidence:**
– The Supreme Court, through a resolution dated 26 October 2007, directed the RTC to receive DNA evidence, guided by the recently promulgated New Rules on DNA Evidence (DNA Rules). This was in light of the nature of the case and the birth of a child, BBB, allegedly fathered by Umanito.
– The Supreme Court directed Deputy Court Administrator Reuben Dela Cruz to monitor and report on the implementation of the DNA Rules.
5. **Hearings and DNA Sample Collection:**
– The RTC set hearings to ascertain the feasibility of DNA testing, where both AAA and BBB (now 17 years old) expressed their willingness to undergo DNA examination.
– The RTC chose the National Bureau of Investigation (NBI) to conduct the DNA testing. Biological samples from AAA, BBB, and Umanito were ordered to be taken, with strict measures to ensure the integrity of the samples as outlined by the Supreme Court.
6. **DNA Test Results:**
– The NBI’s forensic chemist, Mary Ann Aranas, conducted the DNA testing and testified that there was a complete match between Umanito’s alleles and those of BBB.
– The forensic analysis showed a 99.9999% probability of paternity, thereby supporting the presumption that Umanito was indeed BBB’s biological father.
### Issues:
1. **Legal Application of DNA Evidence:**
– Whether the newly implemented DNA Rules can be effectively applied in this case to determine the paternity of the child BBB, which could potentially resolve issues of Umanito’s guilt.
2. **Relevance of Paternity in Establishing Guilt:**
– Whether conclusively establishing Umanito as the biological father of BBB could influence the determination of Umanito’s innocence or guilt regarding the charge of rape.
### Court’s Decision:
1. **Application of DNA Rules:**
– The Supreme Court endorsed the application of DNA testing governed by the new DNA Rules, recognizing the necessity and appropriateness of such scientific evidence to resolve paternity issues and thereby impact the resolution of the actual charge of rape.
2. **DNA Evidence and Guilt:**
– The Court accepted the NBI’s DNA test results indicating a 99.9999% probability that Umanito was the biological father of BBB. This evidence significantly contradicted Umanito’s defense of alibi and claims of not having any sexual relations with AAA.
3. **Procedural Integrity:**
– The Court ensured that all stages of sample collection, analysis, and presentation were documented meticulously, exemplifying procedural rigor and maintaining the chain of custody to preclude any contamination or tampering of evidence.
### Doctrine:
**Doctrine on DNA Evidence:**
– The case establishes the precedent for the application of the New Rules on DNA Evidence in determining issues of paternity. A DNA test result showing a 99.9% or higher probability of paternity creates a disputable presumption of paternity.
### Class Notes:
– **Legal Standards for DNA Evidence:**
– DNA evidence must be collected, preserved, and analyzed with strict adherence to procedural standards to ensure its admissibility and integrity.
– DNA test results with a probability of paternity of 99.9% or higher establish a disputable presumption of paternity.
– **Alibi and Contradictory Statements:**
– The defense of alibi can be significantly undermined by scientific evidence such as DNA testing.
– Inconsistent testimonies by witnesses can influence the outcome but may be overridden by incontrovertible scientific evidence.
### Historical Background:
– **Evolution of DNA Evidence:**
– The introduction and judicial acceptance of DNA evidence represented a major advancement in forensic science, transforming the landscape of criminal prosecutions by providing highly accurate methods for establishing biological relationships.
– **Impact on Filipino Jurisprudence:**
– This case marked the first application of the New Rules on DNA Evidence in the Philippine judiciary, setting a precedent and robust framework for the future utilization of DNA evidence in legal proceedings.
