Insanity as a Defense: Establishing Mental Incapacity in Criminal Proceedings

,

In the case of Verdadero v. People, the Supreme Court acquitted Solomon Verdadero of homicide due to insanity, emphasizing the need to prove a complete deprivation of intelligence at the time of the crime. This ruling clarifies the application of insanity as an exempting circumstance, highlighting that while a history of mental illness is relevant, it must be demonstrably linked to the accused’s state of mind during the commission of the offense. The decision underscores the importance of expert psychiatric testimony and observational evidence in determining an accused’s mental state, providing a framework for future cases involving similar defenses.

From Sanity to Schizophrenia: When Mental Illness Becomes a Legal Defense

The narrative begins on March 12, 2009, when Solomon Verdadero, armed with a Rambo knife, fatally stabbed Romeo Plata. Charged with murder, Verdadero invoked the defense of insanity, citing a long history of mental illness, including diagnoses of depression and schizophrenia. The Regional Trial Court (RTC) convicted him of homicide, a lesser charge, but rejected his insanity plea. The Court of Appeals (CA) affirmed the RTC’s decision, leading Verdadero to elevate the case to the Supreme Court, questioning whether his insanity at the time of the incident was sufficiently established. This case hinges on the interpretation and application of Article 12 of the Revised Penal Code (RPC), which exempts an imbecile or an insane person from criminal liability, unless they acted during a lucid interval. The central legal question is whether Verdadero successfully demonstrated that he was completely deprived of intelligence due to his mental condition at the time of the stabbing.

The Supreme Court, in its analysis, addressed the procedural issue of whether it could entertain factual questions in a petition for review. While generally limited to questions of law, the Court recognized exceptions, including instances where the judgment is based on a misappreciation of facts. It acknowledged that Verdadero’s state of mind at the time of the stabbing was a factual question, but deemed it appropriate to review given the circumstances. The Court then delved into the substantive issue of Verdadero’s insanity, reiterating that the defense must be clearly proven, as there is a presumption that acts penalized by law are voluntary. The burden of proof lies with the accused to demonstrate that they were completely deprived of intelligence at the time of the offense.

The Court considered the undisputed facts that Verdadero had a long history of mental illness, including multiple diagnoses and hospitalizations. It emphasized that a showing of mental disorder does not automatically exonerate an accused. Citing People v. Florendo, the Court reiterated that insanity exists when there is a complete deprivation of intelligence in committing the act. The accused must be deprived of reason, acting without the least discernment due to a complete absence of the power to discern, or experiencing a total deprivation of freedom of the will.

Building on this principle, the Court referenced People v. Isla, which clarified that insanity must relate to the time immediately preceding or simultaneous with the commission of the offense. The accused must demonstrate that they were completely deprived of intelligence because of their mental condition or illness, and that this deprivation was manifest at or immediately before the commission of the offense. Failure to do so results in criminal punishment for the offense committed.

The Court acknowledged the difficulty of proving insanity, noting that it requires an examination of the accused’s mental state, which can only be measured by their behavior. In People v. Opuran, it was explained that the state of a person’s mind can only be judged by their behavior, with insanity evinced by a deranged and perverted condition of the mental faculties manifested in language and conduct. Establishing insanity often requires opinion testimony from those intimately acquainted with the accused, experts such as psychiatrists, or those with a rational basis to conclude insanity based on their own perception.

The Court emphasized the importance of evidence of the accused’s mental condition during a reasonable period before and after the commission of the offense, as stated in People v. Austria. Direct testimony is not required, and a person’s mind can only be plumbed by external acts, allowing for the evaluation of thoughts, motives, and emotions to determine whether external acts conform to those of people of sound mind. Clear and convincing circumstantial evidence would suffice to prove insanity. The Court then diverged from the CA’s conclusion, finding that Verdadero sufficiently proved his insanity at the time of the stabbing.

While there was no direct evidence of Verdadero’s mental state at the precise moment of the crime, the Court considered circumstances immediately before and after the incident, along with the expert opinion of psychiatrist Dr. Ethel Maureen Pagaddu. Dr. Pagaddu testified that Verdadero was suffering a relapse of his schizophrenia at the time of the stabbing. She stated that the mental disorder influenced impulse control and judgment, making it possible that Verdadero could not distinguish right from wrong. This was based on Dr. Juliana’s report of Verdadero’s violent behavior on the day of the incident, leading to the diagnosis of a relapse.

The Court also considered the observations of Maynard Plata, a prosecution witness and Verdadero’s neighbor, who testified that Verdadero often appeared to be of unsound mind and was not in his proper state of mind on the day of the stabbing, noting his reddish eyes and apparent intoxication. These observations aligned with Dr. Pagaddu’s testimony that drinking wine, poor sleep, and violent behavior were symptoms of a relapse. The Court concluded that the evidence supported the finding that Verdadero exhibited symptoms of a relapse of schizophrenia at the time of the stabbing incident.

The Court acknowledged the need for caution in granting absolution based on insanity, to prevent murderers from escaping punishment. However, it found no indication that the defense of insanity was a mere tool for evasion in this case. Verdadero consistently raised the defense from the outset, without resorting to denials or alibis. Thus, the Court exonerated Verdadero on the ground of insanity but ordered his confinement at the National Center for Mental Health for treatment, to be released only upon a court order based on a recommendation from his attending physicians. Even with the exoneration, the Court emphasized that Verdadero remains liable to indemnify the heirs of Romeo Plata for his death. An exempting circumstance admits the existence of criminal and civil liabilities, freeing the accused only from criminal liability.

The Court modified the amount of damages awarded to align with recent jurisprudence, increasing the civil indemnity and moral damages from P50,000.00 each to P75,000.00 each. It also imposed an interest rate of six percent (6%) per annum on all damages awarded, computed from the finality of the decision until fully paid.
