"Amici contend that the phrase “for the purpose of saving the life” is so indefinite and vague that physicians must guess at its meaning and do in fact differ as to the meaning of the phrase. The word “save” has a broad range of possible meanings. The Random House Dictionary lists, inter alia, “to rescue from danger or possible harm...to avoid...the waste of...to treat carefully in order to reduce wear, fatigue, etc....” ...Life may mean the vitality, the joy, the spirit of existence, as well as merely not dying. The possible interpretations of the statute range therefore from a test requiring imminence of death to one which would permit abortion if desirable to preserve an enjoyable life, i.e., a test under which the physician could consider the effect of pregnancy upon the quality of the patient’s life and not merely upon the fact of life as not death. The statute forces the physician to decide at his peril whether a strict or liberal interpretation, or one in between, is the one intended by the statute. It forces him at his peril to make a decision which may be gainsaid by a jury of non-peer laymen whose guess will be as good as his as to the meaning of this statute. In sum the statute fails to provide the certainty required of penal laws."
