The plaintiff, administratrix of the estate of one Duncan Reed, appeals from an order of the Superior Court sustaining the defendants’ demurrer to her amended declaration in which it is alleged that ivhile her intestate was an existing viable child in his mother’s womb he received bodily injury in a collision of automobiles, “causing him to be born prematurely, and which said bodily injuries resulted in his death.” We are asked to reexamine previous decisions of this court and again decide whether a child or his legal representative may recover in an action of tort for prenatal injuries caused by the negligence of a third party who was not the child’s mother.
Our earliest decision was in 1884,
Dietrich
v.
Northampton,
In
Bliss
v.
Passanesi,
In
Cavanaugh
v.
First Natl. Stores Inc.
Since the decisions in the
Bliss
and
Cavanaugh
cases the distinct trend of judicial opinion has been to allow recovery in cases of prenatal injuries caused by negligence. This is shown by the following cases:
Amann
v.
Faidy,
Recent decisions against recovery are found in
Drabbels
v.
Skelly Oil Co.
Reasons generally advanced for recognizing a child’s right of action for prenatal injur}7 are: Natural justice demands recognition of a legal right of a child to begin life unimpaired by physical or mental defects resulting from the injury caused by the negligence of another. A manifest wrong should not go AAdthout redress. Since the law protects an unborn child in the descent and devolution of property whenever it w'ould be for the benefit-of the child and in the enforcement of criminal law7, the unborn child is regarded as a legal entity; therefore by analogy the law should recognize the right of an unborn child not to be injured tortiously by another.
These reasons are urged for denying recovery: The unborn child is a part of its mother. There is lack of precedent for permitting recovery. The principle of stare decisis should be folloAAred. Proof of a causal relation between prenatal *636 injury and the death or resulting condition of the child depends upon speculation and conjecture. Recognition of a cause of action will give rise to fictitious claims.
No new reason has been advanced in recent cases for allowing recovery other than the growing body of precedent in favor of it and the progress made in medical science. A dominant influence on past and current opinion has been the dissenting opinion of Mr. Justice Boggs in
Allaire
v.
St. Luke’s Hosp.
Our decision in the
Dietrich
case was based principally on the lack of supporting precedent at the time it was rendered. The later decisions in the
Bliss
and
Cavanaugh
cases were founded on the doctrine of stare decisis. We have held that “when a debatable question has been considered and definitely decided in a reasonable manner it is usually the part of wisdom, in the absence of important new considerations, to adhere to the decision made.” See
Musolino LoConte Co.
v.
Boston Consol. Gas Co.
We think it advisable that in respect to the subject of prenatal injury the law of this Commonwealth should be in general in harmony with that of the large and growing proportion of the other States which have adopted in principle the rule proposed by Judge Boggs. There is no need to reverse the Dietrich decision which doubtless was right when rendered but we recognize that in view of modern precedent its application should be limited to cases where the facts are essentially the same.
The plaintiff’s declaration alleges receipt of a bodily injury by her intestate when a viable child in his mother’s womb. We interpret the term viable child to mean a foetus so far formed and developed that if then born it would be capable of living. The declaration does not allege with sufficient certainty the fact, if true, that the child was born alive. If the child was stillborn the plaintiff would have no right of action. We think that the plaintiff should have an opportunity to amend her declaration. If she does so and states a cause of action in accordance with this opinion, the case is to stand for further proceedings, otherwise the order sustaining the demurrer is affirmed.
So ordered.
