“136 Mentally disordered persons found in public places. (1) If a constable finds in a place to which the public have access a person who appears to him 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, remove that person to a place of safety within the meaning of section 135 above. (2) A person removed to a place of safety under this section may be detained there for a period not exceeding 72 hours for the purpose of enabling him to be examined by a registered medical practitioner and to be interviewed by an approved social worker and of making any necessary arrangements for his treatment or care….. 139. Protection for acts done in pursuance of this Act (1) No person shall be liable, whether on the ground of want of jurisdiction or any other ground, to any civil or criminal proceedings to which he would have been liable apart from this section in respect of any act purporting to be done in pursuance of this Act or any regulations or rules made under this Act, or in, or in pursuance of anything done in, the discharge of functions conferred by any other enactment on the authority having jurisdiction under Part VII of this Act, unless the act was done in bad faith or without reasonable care. (2) No civil proceedings should be brought against any person in any court in respect of any such act without the leave of the High Court…”
“As I see it, the section is intended to strike a balance between the legitimate interests of the applicant to be allowed, at his own risk as to costs, to seek the adjudication of the courts upon any claim which is not frivolous, vexatious or an abuse of process, and the equally legitimate interest of the respondent to such an application not to be subjected to the undoubted exceptional risk of being harassed by baseless claims, by those who have been treated under the Acts. In striking such a balance, the issue is not whether the applicant has established a prime facie case or even whether there is a serious issue to be tried, although that comes close to it. The issue is whether, on material immediately available to the court, which, of course, can include material furnished by the proposed defendant, the applicant’s complaint appears to be such that it deserves the fuller investigation which will be possible if the intended applicant is allowed to proceed. ”
“(3) In acting under this section the court shall have regard to all the circumstances of the case and in particular to- (a) the length of, and the reasons for, the delay on the part of the [claimant]; (b) the extent to which, having regard to the delay, the evidence adduced or likely to be adduced by the [claimant] or the defendant is or is likely to be less cogent than if the action had been brought within the time allowed by section 11…; (c) the conduct of the defendant after the course of action arose, including the extent (if any) to which he responded to requests reasonably made by the [claimant] for information or inspection for the purpose of ascertaining facts which were or might be relevant to the [claimant]’s cause of action against the defendant; (d) the duration of any disability of the [claimant] arising after the date of the accrual of the cause of action; (e) the extent which the [claimant] acted promptly and reasonably once he knew whether or not the act or omission of the defendant, to which the injury was attributable, might be capable at that time of giving rise to an action for damages; (f) the steps, if any, taken by the [claimant] to obtain medical, legal or other expert advice and the nature of any such advice he may have received. ”
