Guam Insanity is a legal term referring to a specific form of verdict used in Guam's legal system. It is a verdict that can be rendered by a judge or a jury in criminal cases where the defendant has been charged with a crime but claims to have been suffering from a mental illness or defect at the time the offense was committed. This form of verdict is similar to the traditional insanity defense in other jurisdictions, but it has certain unique features specific to Guam. It allows for a more nuanced consideration of mental health issues in criminal cases, taking into account the cultural context and the specific laws and regulations of Guam. When considering a verdict of Guam Insanity, the judge or jury must carefully weigh the evidence presented to determine if the defendant was mentally ill or had a mental defect at the time of the offense. The burden of proof lies with the defense to establish, by a preponderance of the evidence, that the defendant was not able to appreciate the nature and quality of their actions, or that they were unable to conform their conduct to the requirements of the law due to their mental illness or defect. In Guam, there are two main types of Guam Insanity as recognized by the courts. The first is known as "Guilty But Mentally Ill" (GBM), and the second is "Not Guilty by Reason of Insanity" (GRI). The GBM verdict is rendered when the defendant is found guilty of the crime committed but is also determined to have been suffering from a mental illness or defect. In such cases, the defendant would be subject to sentencing like any other guilty person, but with the added provision of psychiatric treatment during their incarceration. On the other hand, the GRI verdict is given when the defendant is acquitted of the charges due to being determined mentally ill or having a mental defect at the time of the crime. In such instances, the defendant is not found responsible for their actions and is typically committed to a psychiatric institution for evaluation, treatment, and potential release if deemed no longer a danger to society. It is important to note that the specific procedures and criteria for rendering a Guam Insanity verdict may vary slightly depending on legislative changes and court interpretations over time. Therefore, it is advisable for defendants, lawyers, and judges to stay informed about the latest legal precedents and guidelines when dealing with cases involving mental health defenses in Guam's legal system.
