The State v Witness Mutengwi

On 26 June 2018 at Mapinge Village, Mutema, Chipinge, the accused (son) allegedly killed his father, Patikai Madaro, by stoning him and striking him several times on the head with a machete and stone. The deceased died from exsanguination (bleeding to death) as confirmed by post-mortem examination. Medical evidence from Dr. Patience Maunganidze confirmed that at the time of the commission of the offence, the accused was mentally disordered. By the time of the trial, the accused had recovered sufficiently to stand trial and was on medication (chlorpromazine) for mental disorder. The State and defence counsel agreed that the matter should proceed under the Mental Health Act [Chapter 15:12]. The accused's maternal grandmother, aged 69 and hypertensive, offered to care for the accused, but evidence showed she and her stroke-afflicted husband were vulnerable and of ill health.

• Whether the accused could be found guilty of murder given his mental disorder at the time of the offence
• Whether the accused possessed the requisite mens rea (mental intention) for murder given his mental state
• What disposition should be made of the accused following a special verdict of not guilty by reason of insanity
• Whether institutionalization or release to family care was appropriate for the protection of the accused and society

1. The accused was found not guilty by reason of insanity. 2. The accused was ordered to be returned to Chikurubi Psychiatric Unit or any other suitable institution for further management and treatment until released by a competent tribunal in terms of the law.

Where an accused person is shown to have been mentally disordered at the time of committing an alleged offence, they cannot form the requisite mens rea (criminal intention) for that offence, and a special verdict of not guilty by reason of insanity must be returned. Following such a verdict, the court has an administrative function to determine the appropriate disposition of the accused, which must prioritize the interests of justice and the protection of both the accused and society. Where the nature of the violent act is vicious, recent in time, and proposed caregivers are vulnerable, institutionalization for continued psychiatric treatment and management is the appropriate order, notwithstanding family willingness to provide care.

The court made several non-binding observations: (1) It noted that the accused's other name was "Jesus" as mentioned emotionally by the witness, but emphasized that decisions cannot be based on emotions. (2) The court took judicial notice of the likelihood of relapse in mental disorder cases when medication is not properly maintained. (3) The court observed that retention at a psychiatric unit serves as a protective measure not only for society but for the accused himself, ensuring regular medication intake, and that the accused would be released by the relevant tribunal when fully recovered. (4) The court commented that the administrative measure of determining post-verdict disposition is important to protect not only the accused but society at large.

This case demonstrates the application of Zimbabwe's Mental Health Act [Chapter 15:12] in criminal proceedings, particularly in murder cases where the accused's mental state at the time of the offence negates criminal capacity. It illustrates the court's approach to balancing the rights and interests of a mentally disordered accused with the safety of the community. The judgment emphasizes that post-verdict administrative decisions regarding institutionalization versus family care must be guided by the interests of justice and public safety rather than emotional considerations, even when family members offer to provide care. The case highlights the importance of proper psychiatric treatment and medication adherence in preventing relapse and protecting both the accused and society.
