Mental illness is a topic that has received a lot of attention when it comes to the application of the legislation. This has allowed for the provision of differentiated treatment to people with mental illnesses. The therapy addresses the person’s abnormal behavior, which could be due to mental illness. Legally, mental illness refers to a mental condition that is characterized by hallucinations and severe mood disturbance, repeated thoughts-form disorder, and/or delusions, which can have a lasting or temporary impact on the person’s mental functioning (Roth 2020). According to the law, mentally ill individuals are those suffering from mental illnesses and who require care and treatment in order to protect their health and safety. This legislation is intended to assess a person’s current health and determine if their condition could deteriorate. If so, it may lead to deviant behavior that can be considered illegal. To be considered mentally ill by the criminal justice system, a person must first be diagnosed with psychosis and/or a more serious type of mental illness. From both a criminal and civil perspective, the law has an important role in improving mental health. It provides relevant and sustained care that allows this group of vulnerable people to attain the standards of normative behaviour that improves their cognitive skills and social skills, and integrates them into society. (Roth 2020). This legislation provides a reliable method of determining mental health. It allows for the administration of justice to give mentally ill people different treatment depending on their circumstances.
According to available evidence, people with mental illnesses were often treated poorly while they were in jail or awaiting trial. Lack of access to specialist treatment for mental illnesses inmates may suffer a serious deterioration of their health or die from the disease. The American Psychological Association released a study that found that despite attempts by government to improve conditions in prisons, the same situation has existed for three decades within the criminal justice system (Stringer 2019, 2019).
