turbed and upset,” that abortions represent a sense of loss to a woman and “[i]t is certainly not unreasonable to expect someone after an abortion, even though she thinks she ought to have an abortion, to be depressed.”
However, Dr. Smith did not testify that Sandra was suffering from an uncontrollable impulse at the time of the suicide or that she did not understand the consequences and risks of her acts. To the contrary, Dr. Smith testified that on the night of the suicide, in his opinion, Sandra had not lost control, she was fully aware of the purpose and physical effect of her act of when she jumped into traffic, she knew what the purpose was and the effect, and that if she desired she could have controlled her actions.
This expert testimony was consistent with the observations of plaintiff and other family members who testified that, although Sandra experienced behavioral changes after the abortion, she appeared to be in control of her actions, generally functioned normally, and had done nothing foolish and was not acting “crazy” or “nuts.”
There was no substantial evidence that Sandra’s suicide was committed while she was insane in the sense she was suffering from an uncontrollable impulse or while she did not understand the consequences of her acts. Without such evidence, plaintiff failed to make a submissible case on the issue of whether defendant’s failure to obtain a psychiatric history or to monitor Sandra’s mental health proximately caused her death by suicide. Causation was an essential element of her case. Accordingly, the error in jury Instruction No. 8 was not prejudicial.
II.
Plaintiff next asserts the trial court preju-dicially erred in submitting Instruction No. 7, the verdict director, to the jury. We need not address this contention because, even if the instruction were erroneous, our finding that there was no submissible case would render any such error non-prejudicial.
III.
Plaintiff last asserts that the trial court erred in dismissing her claim of statutory negligence based on § 188.028 RSMo, governing consent of minors to abortions. She argues that she was in the class of persons protected by the statute and was not a party to the action in which the statute’s enforcement was enjoined, and thus was not bound by the injunction.
A statute may be pleaded as defining the applicable standard of care in negligence actions under certain conditions. Monteer v. Prospectors Lounge, Inc., 821 S.W.2d 898, 900 (Mo.App.1992). However, “[t]he invalidity of an enactment will usually mean that it should have no effect under any theory in setting the proper standard of conduct.” Harper, James & Gray, The Law Of Torts § 17.6 (2d ed. 1986). See, e.g., Bertrand v. DiCarlo, 111 R.I. 509, 304 A.2d 658, 661 (1973).
On November 4, 1983, the federal district court for the Western District of Missouri found § 188.028 unconstitutional and enjoined the State of Missouri from applying, implementing, relying upon, enforcing or threatening to enforce § 188.028, pending the promulgation and adoption of civil procedure rules by the Missouri Supreme Court consistent with the U.S. Constitution. T.L.J. v. Ashcroft, 585 F.Supp. 712, 713 (W.D.Mo.1983). The order was to remain in effect until further order of the court. Id. This order remained in force until it was vacated on August 7, 1985. C.L.G. v. Webster, 616 F.Supp. 1182, 1186 (W.D.Mo.1985).
Sandra consented to and had the abortion on October 27, 1984 which was during the period the injunction was in force and the statute was deemed invalid. At that time, the statute could not be used to define a duty of care or standard of conduct. This result applies even if plaintiff was in the class the statute purported to protect and was not a party to the proceeding declaring it unconstitutional. The trial court properly struck the reference to § 188.028.
The judgment of the trial court is affirmed.
