SC: Psychiatric Records Not Required for Insanity Defense

By Gerome Dalipe IV

The Supreme Court has ruled that a defendant is not required to present a documented history of mental illness to successfully claim legal insanity as a defense.

In a landmark decision penned by Associate Justice Alfredo Benjamin S. Caguioa of the court’s Third Division, the SC acquitted an accused of homicide on grounds of insanity and ordered her confinement at the National Center for Mental Health (NCMH) for treatment.

The case involved a woman charged with killing her best friend. Her father discovered her naked, covered in blood, and chanting religious phrases over her friend’s lifeless body.

The accused claimed she attacked her friend after witnessing her transform into a demonic figure with horns.

She also testified that she heard the Virgin Mary instruct her to place a cross into the victim’s heart and perform other acts.

The Regional Trial Court and the Court of Appeals had earlier found her guilty, rejecting her insanity defense.

Both courts argued that her mental state needed to be evaluated before, during, and after the crime.

They ruled that post-crime psychiatric examinations were insufficient to establish her mental condition at the time of the offense.

The SC overturned these rulings, emphasizing that under Article 12 of the Revised Penal Code, a person is exempt from criminal liability if they were legally insane at the time of the crime and unable to understand the wrongfulness of their actions.

The tribunal clarified that proving legal insanity does not require prior medical records.

Instead, evidence of the defendant’s behavior before, during, or immediately after the crime can be sufficient to establish insanity.

While prior psychiatric documentation can be helpful, its absence should not disqualify an insanity defense.

“The requirement for prior medical records disproportionately disadvantages impoverished individuals, who often lack access to regular psychiatric care due to economic constraints,” the SC ruled.

“The plea of insanity, like any other defense available under the law, must be equally accessible to all, regardless of background or status.”

Although acquitted of the criminal charge, the accused has been ordered confined to the NCMH for further evaluation and treatment.

Her release will depend on the recommendation of her attending physician and approval from the Regional Trial Court.
