As to the ascertaining of a child’s age

(1) When the exact age of any child subject or likely or alleged to be subject to this Act is unascertainable, it shall be sufficient for all purposes of this Act to ascertain the approximate age of the child. (2) A person acting bona fide under this Act shall not be liable in any action for any act done thereunder where the plaintiff claims damages upon the ground that he was either over or under a certain age when the act complained of was done. (3) The age of a child shall be determined at the time of his entry into an institution, either by the court or by the manager in consultation with the parent or guardian of the child, and the age then determined shall be taken to be the age of such child during the whole term of his residence at the institution unless (Children’s Reformation) 17 legal documentary evidence be produced to prove that his age is otherwise.
