MSFinals-1235

A 26-year-old man has been brought to the Psychiatric Ward by his family members who are concerned about his mental health. They believe he needs to be admitted to the hospital to be formally assessed by Psychiatry. He has been detained under the Mental Health Act (MHA), as he would not agree to be admitted voluntarily. The situation is not an emergency.
What is the appropriate duration for the Section to be valid when admitting this patient under the MHA for assessment?
