In "Northern Ireland Health and Social Services Board v A and Others" NIJB 1, Lord Justice MacDermott said that he was "satisfied that the statutory phrase, 'for the purpose only of preserving the life of the mother' does not relate only to some life-threatening situation. Life in this context means that physical or mental health or well-being of the mother and the doctor's act is lawful where the continuance of the pregnancy would adversely affect the mental or physical health of the mother. The adverse effect must however be a real and serious one and there will always be a question of fact and degree whether the perceived effect of non-termination is sufficiently grave to warrant terminating the unborn child."
