(a)the Society or a hospital if, after the Society or the hospital, as the case requires, had taken blood to be supplied for the purpose of being administered to a person or used in the preparation of a blood product to be administered to a person, the Society or the hospital had reasonable grounds for believing that —

(i)a statement in the declaration made by the donor of that blood under the Transmissible Diseases Regulations might be false or misleading; or

(ii)that blood or blood product might contain AIDS,

and the Society or the hospital did not take all reasonable steps to ensure that that blood or blood product was not administered to a person; or

(b)any employee or person referred to in subsection (1)(a)(ii) if, after the Society or the hospital concerned or that employee or person had taken blood to be supplied for the purpose of being administered to a person or used in the preparation of a blood product to be administered to a person, that employee or person had reasonable grounds for believing that —

(i)a statement in the declaration made by the donor of that blood under the Transmissible Diseases Regulations might be false or misleading; or

(ii)that blood or blood product might contain AIDS,

the administration to the person referred to in paragraph (a) of any blood or blood products in respect of which the testing referred to in subsection (1)(a)(i)(B) had not been carried out does not by itself defeat a defence provided by subsection (1).

6.AIDS related actions against people administering blood, defences to

(a)a hospital (in this section called the administering hospital) or other person at whose premises blood supplied by the Society or a hospital, or a blood product derived from blood so supplied, was administered to a patient; or

(b)a medical practitioner or a person acting on behalf of a medical practitioner who administered to a patient, or authorised the administration to a patient of, blood supplied by the Society or a hospital, or a blood product derived from blood so supplied,

(d)caused, before that blood was supplied to be administered to a person, or to be used in the preparation of a blood product to be so administered, a sample of that blood to be tested, using such equipment and in accordance with such a method as were then required by good medical practice, for the presence of AIDS, and that the result of that test was negative; and

(e)was not guilty of any negligence or wilful misconduct in respect of the taking or testing of that blood or of the storage, preparation, processing, handling, supplying, labelling or other documenting, or administering of that blood or of the relevant blood product derived from that blood, as the case requires.

(b)the administering hospital or other person referred to in subsection (1)(a) if, at any time up to and including the time at which the relevant blood or blood product was administered, the administering hospital or that other person —

(i)had reasonable grounds for believing that that blood or blood product might contain AIDS; and

(ii)had not taken all reasonable steps to ensure that that blood or blood product was not administered to a person;

the administration to the person referred to in paragraph (a) of any blood or blood products in respect of which the testing referred to in subsection (1)(d) had not been carried out does not by itself defeat a defence provided by subsection (1).
