We have this week seen introduction to Parliament of a Mental Health Bill for its consideration. What follows is the full, amended text of sections 135 and 136 Mental Health Act 1983, including s136B, as they will be if and only if the Bill makes its way through Parliament to Royal Assent without amendment.
NB! – this is NOT the current law as of 07th November 2017 – this is the law as it may become, following the passage of a Bill which may be amended or even withdrawn before bringing the below in to effect. This is just to make it readable as a proposition. These amendments are outlined in Clause 46 of the Mental Health Bill 2024.
- The current wording of section 135
- The current wording of section 136, inc 136B.
As the Bill progresses, I’ll edit this page is further amendment alters the below so it should remain as up to date as I remain and I will be monitoring the Bill’s progress.
Section 135
Warrant to search for and remove patients.
(1) If it appears to a justice of the peace, on information on oath laid by an approved mental health professional, that there is reasonable cause to suspect that a person believed to be suffering from mental disorder—
(a) has been, or is being, ill-treated, neglected or kept otherwise than under proper control, in any place within the jurisdiction of the justice, or
(b) being unable to care for himself, is living alone in any such place, the justice may issue a warrant authorising any constable to enter, if need be by force, any premises specified in the warrant in which that person is believed to be, and, if thought fit, to remove him to a place of safety with a view to the making of an application in respect of him under Part II of this Act, or of other arrangements for his treatment or care.

Section 136
Removal of mentally disordered persons without warrant.
(1) If a person appears to a constable to be suffering from mental disorder and to be in immediate need of care or control, the constable may, if he thinks it necessary to do so in the interests of that person or for the protection of other persons—

Section 136B
Extension of detention
(1) The registered medical practitioner who is responsible for the examination of a person detained under section 135 or 136 may, at any time before the expiry of the period of 24 hours mentioned in section 135(3ZA) or (as the case may be) 136(2A), authorise the detention of the person for a further period not exceeding 12 hours (beginning immediately at the end of the period of 24 hours).
(2) An authorisation under subsection (1) may be given only if the registered medical practitioner considers that the extension is necessary because the condition of the person detained is such that it would not be practicable for the assessment of the person for the purpose of section 135 or (as the case may be) section 136 to be carried out before the end of the period of 24 hours (or, if the assessment began within that period, for it to be completed before the end).

I am not a police officer.
I try to keep this blog up to date, but inevitably over time, amendments to the law as well as court rulings and other findings from inquests and complaints processes mean it is difficult to ensure all the articles and pages remain current. Please ensure you check all legal issues in particular and take appropriate professional advice where necessary.
