We agree with the Appellate Court that this case must be reversed and remanded for new trial. However, we have granted certiorari because we are fearful that the Appellate Court’s view of a proper instruction on contributory negligence may be misleading to the trial court. The Appellate Court expressed the view that it is for the jury to determine whether contributory negligence exists, and if the jury finds contributory negligence exists, the jury has the discretion of denying plaintiff any recovery, or permitting plaintiff to recover irrespective of plaintiff’s contributory negligence, citing Sisler v. Jackson, Okl.,
In Sisler the trial court used the permissive “may” (as distinguished from “should” or “must”) in reference to plaintiffs’ contributory negligence. We did not approve the permissive “may” in that case but excused it in view of the comprehensive statement of law applicable to contributory negligence contained in the trial court’s instruction No. 5.

In Dickinson v. Cole,
The receiver for the railroad company (Dickinson) contended in this court and in the Supreme Court of the United States that the railroad company had a vested right in the common law defense of contributory negligence which (he contended) was made permanent, or frozen in, by the 14th amendment to the U. S. Constitution. Both courts rejected that view.
The Supreme Court of the United States simply affirmed this court’s holding that article 23, § 6, did not contravene the 14th Amendment of the Constitution of the United States. Chicago, R. I. & P. R. Co. v. Cole,
What language should be used in contributory negligence instructions (whether “may”, “should” or “must”) has received attention in writings by members of the Oklahoma Bar in recent years. See Article by Jefferson G. Greer in 40 O.B.J. 1781 (1969), and the Author’s Comment in the 1969 Pocket Part of 6 Vernon’s Oklahoma Forms § 6935, by Richard K. McGee. Mr. Greer cites St. Louis-San Francisco Ry. Co. v. Robinson,
The year 1934 marks a departure from some of our earlier decisions. In 1934 in Miller v. Price,
“The defense of contributory negligence under section 6, art. 23, of the Constitution, being made a question of fact to be determined by the jury, it is the duty of the court in such cases, where an instruction on this theory is asked, to instruct the jury that one who has negligently contributed to his own injury cannot recover, and a refusal to give such instruction when asked is error.”
We then said: “Other cases to the same general effect are: * * * St. Louis-S.F.R. Co. v. Robinson,
We concluded that the rule laid down by the prior decisions, when literally applied, was too broad and would result in confusion in cases tried by juries. Therein we said:
“We cannot follow in full the construction heretofore placed on said constitutional provision, notwithstanding the *405 numerous cases in which said provision was considered * *
In the Miller case the defendant had pled contributory negligence and the trial court gave an instruction on contributory negligence, although there was no evidence of contributory negligence. The jury found for the defendant and plaintiff appealed. After reviewing previous decisions the court said:
“ * * * From a review of the above cases, it is apparent that we have approached this intolerable position: That whenever contributory negligence is pleaded it is the duty of the court to instruct the jury thereon, even though there is no evidence whatever presented to support such allegation, or from which contributory negligence may be inferred. We cannot assent to such a doctrine. * * * It was not the intention of the framers of the Constitution to confer judicial power on the jury but rather to emphasize the fact that the jury is the trier of the facts, and that, in so far as contributory negligence and assumption of risk are concerned, the facts upon which said defense are based would be passed upon by a jury without interference on the part of the court.”
We followed Miller v. Price, supra, in Goodridge v. Davis, Okl.,
Mr. McGee, in the Author’s Comment which we have cited, relied upon the Cole and Robinson cases, supra, together with Layton v. Rocha,
We have examined the Layton case and note that the Supreme Court of Arizona tolerated the use of the word “may” but stated unequivocally, “ * * * We think the preferable form is that in the event of contributory negligence the jury ‘should’ find for the defendant.”
The cause is reversed and remanded to the trial court with instructions to give contributory and primary negligence instructions which use the word “should” or “must” as distinguished from the word “may”.
