MHA 1983 s3 is the civil section used to admit patients for treatment.
From 3/11/08, the admission criteria are:
As for s2:
The AMHP must consult the person (if any) appearing to be the nearest relative before making the application - unless "such consultation is not reasonably practicable or would involve unreasonable delay" - and the s3 cannot go ahead if the NR objects (s11(4)). An objection perceived to be unreasonable could lead to displacement proceedings under s29.
It is often to said to last for 6 months; however, this is just the period it would last if the patient were not discharged sooner, or the section not renewed for a further period (s20(1)). The section can be renewed by the RC (with the co-operation of another professional from a separate profession) for a further 6-month period, and at yearly intervals thereafter (s20(2)).
During the course of the section, leave may be granted by the RC under s17, and the patient may be transferred to another hospital under s19.
The patient can be forcibly medicated, and the Consent to Treatment provisions apply (s56).
Usually, when discharged, a patient is completely discharged from the provisions of the Mental Health Act, but from 3/11/08 a patient can be discharged subject to a Community Treatment Order.
