OPINION
This appeal is from a judgment of the United States District Court for the District of Arizona in favor of defendantsappellees in a diversity action brought by plaintiffs-appellants to recover for personal injuries suffered in an automobile accident in 1969. We affirm.
THE CASE
Plaintiffs-appellants instituted this action in the Superior Court of the State of Arizona in and for the County of Maricopa to recover damages for personal injuries resulting from collision of *1032 their automobile with one driven by Linda Joyce Berryhill and owned by Adrian Berryhill and Gladys Berryhill. The action was removed by defendants to the District Court for the District of Arizona and tried before a jury. At the close of plaintiffs’ case, motion was made for a directed verdict in favor of Adrian Berryhill and Gladys Berryhill on the ground that no liability had been established under the family purpose doctrine. The trial judge reserved ruling on the motion until both sides had rested, at which time thе motion was granted, leaving for the jury the case against defendant Linda Joyce Berryhill.
Pertinent portions of the instructions to the jury are set forth below:
Don’t single out any one thing I may say as stating the law, but consider my instructions as a whole.
Now the defendant [Linda Joyce Berryhill] here claims as a defense that even if you should find that she was negligent in the operation of her automobile, the claim then is that the plaintiff was likewise negligent, guilty of contributory negligence. Now whether or not the plaintiff was so contributorily negligent is to be determined by you under the same rules as I have given you already with referеnce to the question of negligence and proximate cause.
Contributory negligence then is negligence on the part of the plaintiff which, combining with the negligence of the defendant, contributes in proximately causing the injury to the plaintiff.
If the conduct of both plaintiff and defendant was negligеnt and if the negligence of each, considered separately, was a proximate cause of the accident, then in such a case the plaintiff should not recover.
On the other hand, if you should unanimously find from a . preponderance of the evidence in the case, that the plaintiff was guilty of some contributory negligence and that plaintiffs’ fault contributed as a proximate cause of any injuries which plaintiffs may have sustained, you will not then be concerned with the issue as to damages, but will return a verdict for the defendant.
And so if you find that the plaintiffs were negligent and that such negligence contributed as a proximate cause, yоur verdict should be for the defendant.
Contributory negligence then is negligence which, co-operating in some degree with the negligence of another, contributes in proximately causing the accident. The one who is contributorily negligent should not recover from another no matter how negligent the other may have been.
If you find that Atkin Seltzer was negligent, then such negligence, under the law, is imputed to his wife, Helen Seltzer, and she may not recover from the defendant in that event; in other words, she cannot recover in the event Mr. Seltzer was contributorily negligent or was the sole cause of the accident. [Emphasis supplied.]
Appellants’ counsel objected to the judge’s instructions on the ground that they contained the mandatory terms “will” and “cannot” in discussing contributory negligence; whereas Arizona law requires the permissive term “should.” Counsel also stated that he felt the error could not be corrected without emphasizing contributory negligence to the jury. 1 Thereafter the trial judge instructed the jury:
Ladies and gentlemen, in the course of my instructions with you in connection with the question of contributory negligence, I may have made a mis *1033 statement as to what the law is in the State of Arizona.
I should have said to you that if you find that Mr. Seltzer was contributorily negligent, then you should not— should not find a verdict for Mrs. Seltzer. [Emphasis supplied.]
Appellants’ counsel again objected on the ground that the cоrrected instruction omitted the instruction of proximate cause. Thereafter the trial judge instructed the jury as follows:
In connection with the instruction on contributory negligence, it is necessary, of course, that if you find there was contributory negligence, that you further find that that contributory negligence was the proximate cause of the injuries — a proximate cause of the injuries. And so if you find that there was contributory negligence and that that contributory negligence proximately caused the injury, then you would not find, or you should not, rather, I should say, under the Arizona law, you should not find a verdict for Mrs. Seltzer. [Emphasis supplied.]
The jury returned a verdict for defendant Linda Joyce Berryhill, and judgment was entered in favor of all appellees.
Appellants contend that the trial judge committed incurable error requiring an automatic mistrial when he gave the jury mandatory instructions on contributory negligence (“will return a verdict for the defendant” and “cannot recover in the event Mr. Seltzer was contributorily negligent”), rather than the permissive instructions required by Arizona law (“should find for the defendant”). Error is also asserted for unduly emphasizing contributory negligence to the jury because of the two curative instructions. Finally, appellants argue that the evidence viewed most favorably to them adequately supports the application of the family purpose doctrine to this case; that, therefore, the trial judge erred in directing a verdict for defendant Linda Joyce Berryhill’s parents. 2
OPINION
Arizona Law
The Constitution of Arizona, Article XVIII, § 5, A.R.S., contains a rather unusual provision which appears to have its only counterpart in Article XXIII, § 6 of the Oklahoma Constitution:
The defense of contributory negligence or of assumption of risk shall, in all cases whatsoever, be a question of fact and shall, at all times, be left to the jury.
Under this provision, the jury has not only the right to determine the facts, but also to apply or not apply, as it sees fit, the law of contributory negligence as a defense. Heimke v. Munoz,
Appellants have cited no case and we have discovered none, holding that a mandatory instruction on contributory negligence under Arizona law is an incurable error requiring an automatic mistrial. However, appellants argue that the following statement in Heimke *1034 suggests that an automatic mistrial is required:
At the conclusion of the court’s instructions to the jury, counsel for plaintiffs[ 4 ] indicated to the court that he did not know how the instruction could now be corrected but that he wished to renew his objection. Counsel for defendant then suggested that the instruction be repeated in a corrected form; to which plaintiffs stated that this would only emphasize that particular aspect of the litigation. We think it sufficient to say that a party cannot be put to a choice of two evils, neither of which is of his making. We do not find a waiver of the error under these circumstances.
In that case, which involved an automobile collision, the plaintiffs refused to let the trial judge read the corrected instruction, and the defendant argued that this constituted waiver of the right to claim error on appeal. Although the court found no waiver, the important point is that the corrected instruction was never given to the jury. Thus, the jury was sent out for deliberations with the incorrect instruction, leaving the Supreme Court of Arizona no choice but to reverse. Accordingly, the statement regarding “choice of two evils” is dictum at most. See Kelch v. Courson,
Applicability of Federal Procedural Rules and Law
The U. S. Supreme Court has made it clear that under the
Erie
doctrine
5
state law is not controlling over the Federal Rules of Civil Procedure. Hanna v. Plumer,
We are persuaded by the foregoing authorities and hold that federal procedural rules and law control the manner and method of instructing the jury in federal courts.
Were the Trial Judge’s Erroneous Instructions on Contributory Negligence Cured by His Subsequent Instructions?
In Mercer v. Theriot,
Erroneous instructions can be corrected by the trial judge only by expressly correcting them and by directing the members of the jury to expunge the erroneous statements from their minds. Puget Sound Navigation Co. v. Nelson,
It is well settled that instructions must be considered as a whole. Russo-Chinese Bank v. National Bank of Commerce,
In the case before us, the initial instructions employed the proper permis *1036 sive term “should,” but they also used the improper terms “will” and “cannot,” which rendered them erroneous under the substantive law of the Arizona Constitution. The jury could have been misled or confused over whether contributory negligеnce was a mandatory or permissive consideration. Subsequently, the trial judge specifically called the jury’s attention to the error and to the correct law of the State of Arizona. He distinctly and particularly pointed out what the law was and, in our opinion, left no doubt in the minds of the members of the jury on that point. Clear and unmistakable words were used in his curative instructions, and the error itself was not repeated or emphasized.
Accordingly, we hold that the trial judge’s erroneous instructions were properly and effectively cured. To follow appellants’ advocacy оf a rule of absolute incurability of an erroneous instruction on contributory negligence would not only frustrate the purpose of Rule 51 of the Federal Rules of Civil Procedure, but would also diminish the integrity of the federal jury trial system.
Further, we are not persuaded that the curative instructions of the trial judge unduly emphasized contributory negligence to the jury. The first curative instruction, although necessary to properly state the Arizona law, was concise in pointing out the error in one sentence and correcting it in another. The second curative instruction was also concise and repeated the correct statement on contributory negligence merely in the context of an instruction on proximate cause, the instruction having been requested by appellants. It may be observed that there is no requirement that a charge on proximate cause accomрany each charge on contributory negligence. Bass v. Dehner,
Family Purpose Doctrine
The remaining contention of appellants is that the trial judge erred in directing a verdict in favor of the defendant-driver’s parents on the basis that the defendant-driver’s parents were entitled to judgment as a matter of law under the family purpose doctrine. That doctrine places derivative liability upon a family head who controls the use of or furnishes an automobile to a member of the family. Pesqueira [sic] v. Talbot,
The judgment of the district court is affirmed.
Affirmed.
Notes
. This first objection made appellants’ position sufficiently clear to avoid any need to repeat the objection. Union Pacific R.R. v. Owens,
. Appellants’ argument that Arizona decisions upholding imputed contributory negligence of a husband-driver to wife-passenger should be abrogated was abandoned at oral argument.
. It follows that if a verdict “should” be for the defendant, then it “should not” be for the рlaintiff. Because the word “should” is conditional, the phrase “should not” is also conditional. Shaya v. Petzoldt,
. Counsel for plaintiffs-appellants in Heimke and the instant case are identical.
. Erie R.R. v. Tompkins,
. In a previous case the Court held that Rule 3 was
not applicable
and that a Kansas statute, requiring service of a summons on a defendant to commence an action, controlled. Ragan v. Merchants Transfer & Warehouse Co.,
. Rule 51 provides:
At the close of the evidence or at such earlier time during the trial as the court reasonably directs, any party may file written requests that the court instruct the jury on the law as set forth in the requests. The court shall inform counsel of its proрosed action upon the requests prior to their arguments to the jury, but the court shall instruct the jury after the arguments are completed. No party may assign as error the giving or the failure to give an instruction unless he objects thereto before the jury retires to consider its verdict, stating distinctly the matter to which he objects and the grounds of his objection. Opportunity shall be given to make the objection out of the hearing of the jury. [Emphasis supplied.]
