Statute of Limitations (Amendment) Act 1991
Date of knowledge for the purposes of this Act.
2.—(1) For the purposes of any provision of this Act whereby the time within which an action in respect of an injury may be brought depends on a person's date of knowledge (whether he is the person injured or a personal representative or dependant of the person injured) references to that person's date of knowledge are references to the date on which he first had knowledge of the following facts:
(a) that the person alleged to have been injured had been injured,
(b) that the injury in question was significant,
(c) that the injury was attributable in whole or in part to the act or omission which is alleged to constitute negligence, nuisance or breach of duty,
(d) the identity of the defendant, and
(e) if it is alleged that the act or omission was that of a person other than the defendant, the identity of that person and the additional facts supporting the bringing of an action against the defendant;
and knowledge that any acts or omissions did or did not, as a matter of law, involve negligence, nuisance or breach of duty is irrelevant.
(2) For the purposes of this section, a person's knowledge includes knowledge which he might reasonably have been expected to acquire—
(a) from facts observable or ascertainable by him, or
(b) from facts ascertainable by him with the help of medical or other appropriate expert advice which it is reasonable for him to seek.
(3) Notwithstanding subsection (2) of this section—
(a) a person shall not be fixed under this section with knowledge of a fact ascertainable only with the help of expert advice so long as he has taken all reasonable steps to obtain (and, where appropriate, to act on) that advice; and
(b) a person injured shall not be fixed under this section with knowledge of a fact relevant to the injury which he has failed to acquire as a result of that injury.
