The Mental Health Act is a law that provides guidelines for the treatment and care of individuals with mental health conditions. It allows for the involuntary admission of patients to hospitals if they pose a risk to themselves or others. The Act aims to protect the rights of these individuals while ensuring they receive necessary treatment. Under the Mental Health Act, patients have specific rights, including the right to appeal their detention and the right to receive information about their treatment. The Act also emphasizes the importance of consent and the need for mental health professionals to consider the least restrictive options for care.
