Res Ipsa Loquitur

The doctrine of res ipsa loquitur is an exception to the rule that hearsay evidence is devoid of probative value. This is because the doctrine of res ipsa loquitur establishes a rule on negligence, whether the evidence is subjected to cross-examination or not. It is a rule that can stand on its own independently of the character of the evidence presented as hearsay.

Res Ipsa Loquitur

The doctrine of res ipsa loquitur is an exception to the rule that hearsay evidence is devoid of probative value. This is because the doctrine of res ipsa loquitur establishes a rule on negligence, whether the evidence is subjected to cross-examination or not. It is a rule that can stand on its own independently of the character of the evidence presented as hearsay.

The Supreme Court Decides: Failure to prove the integrity of the corpus delicti renders the drugs seized insufficient to prove guilt beyond reasonable doubt.

In ascertaining the liability of accused-appellant for violation of Republic Act No. 9165, it is imperative to determine whether the identity of the dangerous drugs allegedly confiscated from him were established with moral certainty. The dangerous drugs form an integral part of the corpus delicti of the crime. Failure to prove the integrity of the corpus delicti renders the drugs seized insufficient to prove his guilt beyond reasonable doubt. Thus, warranting his acquittal.

The Supreme Court Decides: Each link in the chain of custody must be established to ensure that the integrity and evidentiary value of the seized items are preserved.
