84.Section 44(4) sets out the criteria for short-term detention. These criteria are similar to the criteria for compulsory treatment orders (see Part 7). However, because short-term detention may be required when the nature and effect of the patient’s mental disorder is not clear, it is unnecessary to demonstrate that medical treatment is available which would benefit the patient. Instead, the approved medical practitioner must be satisfied that it is necessary to detain the patient for the purpose of either determining what treatment should be given or administering medical treatment.
