(1)Subject to the provisions of this section, a person shall not be guilty of an offence under the law relating to abortion when a pregnancy is terminated by a registered medical practitioner if two registered medical practitioners are of the opinion, formed in good faith—
(a)that the continuance of the pregnancy would involve risk to the life of the pregnant woman, or of injury to the physical or mental health of the pregnant woman or any existing children of her family, greater than if the pregnancy were terminated; or
(b)that there is a substantial risk that if the child were born it would suffer from such physical or mental abnormalities as to be seriously handicapped.
(2)In determining whether the continuance of a pregnancy would involve such risk of injury to health as is mentioned in paragraph (a) of subsection (1) of this section, account may be taken of the pregnant woman's actual or reasonably foreseeable environment.
(3)Except as provided by subsection (4) of this section, any treatment for the termination of pregnancy must be carried out in a hospital vested in the Minister of Health or the Secretary of State under the National Health Service Acts, or in a place for the time being approved for the purposes of this section by the said Minister or the Secretary of State.
(4)Subsection (3) of this section, and so much of subsection (1) as relates to the opinion of two registered medical practitioners, shall not apply to the termination of a pregnancy by a registered medical practitioner in a case where he is of the opinion, formed in good faith, that the termination is immediately necessary to save the life or to prevent grave, permanent injury to the physical or mental health of the pregnant woman.
