The approved mental health professional and the nearest relative: detention need not be negligent, even if it is unlawful

A patient may be detained under section 3 of the Mental Health Act 1983 (HM Government, 1983) only if his nearest relative does not object. Whether an objection has been made will be a question for the approved mental health professional (AMHP) concerned, but their answer will have to be a reasonable one. If the belief of the AMHP is not reasonable, a patient's section 3 admission will be unlawful. That does not mean, however, that the AMHP's conduct will necessarily be negligent, or that the patient will be entitled to damages.
