G.R. No. 184528; April 25, 2012
NILO OROPESA, Petitioner, vs. CIRILO OROPESA, Respondent.

FACTS

Petitioner Nilo Oropesa filed a petition for guardianship over the properties of his father, respondent Cirilo Oropesa, alleging that due to age, medical ailments including strokes, and impaired memory and judgment, Cirilo had become incapable of managing his affairs and was vulnerable to exploitation. The Regional Trial Court (RTC) directed a social case study, but the respondent refused to be interviewed. After the petitioner presented testimonial evidence from himself, his sister, and a former nurse, he filed a manifestation resting his case but failed to formally offer his evidence in writing.
The respondent filed an Omnibus Motion to declare the petitioner to have waived his offer of evidence and to expunge the unoffered documents, which the RTC granted. The respondent then filed a demurrer to evidence, arguing the petitioner failed to establish incompetence. The RTC granted the demurrer and dismissed the petition, a ruling affirmed by the Court of Appeals.

ISSUE

Whether the Court of Appeals erred in affirming the dismissal of the petition for guardianship based on the grant of the demurrer to evidence.

RULING

The Supreme Court denied the petition and affirmed the lower courts’ rulings. The core legal logic rests on two fundamental principles: the stringent standard for establishing incompetence in guardianship proceedings and the mandatory procedural rule on the formal offer of evidence.
First, a guardianship is a profound trust relation intended to protect a ward proven incapable of self-care or property management. The burden of proof rests heavily on the petitioner to demonstrate such incompetence by clear and convincing evidence. The petitioner’s evidence, even if considered, consisted merely of general allegations of illness and lapses, which were insufficient to overcome the presumption of sanity and competence enjoyed by every individual. The respondent’s refusal to participate in the social study did not shift this burden or constitute an admission of incapacity.
Second, and decisively, the petitioner’s failure to formally offer his evidence was fatal to his case. The Rules of Court require that testimonial and documentary evidence be formally offered after presentation to become part of the record and basis for a judgment. By resting his case without a written formal offer, the petitioner waived the presentation of his evidence. Consequently, the RTC correctly granted the motion to expunge and treated the record as devoid of competent evidence for the petitioner. With no evidence properly before it, the trial court acted correctly in granting the demurrer to evidence, which tests the sufficiency of the plaintiff’s evidence, and dismissing the petition without need for the respondent to present his side. Procedural rules are not mere technicalities but essential to the orderly administration of justice.
