White v. Powell, 346 Mo. 1195, 145 S.W.2d 375, and the cases therein cited, as holding that such is not a plea of contributory negligence; and we note also Smith v. Kansas City Public Service Co., Banc, 328 Mo. 979, 43 S.W.2d 548, 555. Counsel for defendants in their brief and reply brief apparently regard plaintiff’s objection to the plea as one going to its generality, citing cases to the effect that a general plea of contributory negligence is good if not attacked by motion. State ex rel. Shell Petroleum Corp. v. Hostetter, 348 Mo. 841, 156 S.W.2d 673; Kobusch v. Ruberoid Co., 355 Mo. 48, 194 S.W.2d 911. That is not the question primarily involved here; the question actually is whether, as stated in Smith, supra, this allegation was “merely a denial of plaintiff’s cause of action,” since it actually sought to cast all negligence upon plaintiff and thereby sought to exonerate the defendants. Our forms of pleading have been substantially liberalized under the Civil Code (section 509.040 RSMo 1949, V.A.M.S.) but there is still a substantive difference between contributory negligence and proximate cause negligence. In this instance, however, we find it unnecessary to decide whether this allegation might, under any circumstances, have operated as a plea of contributory negligence, for the reasons now to be stated. In passing, however, we may say that it is certainly not to be recommended.
It has been stated in various cases that if contributory negligence has been pleaded and if there is substantial evidence thereof, it is error for a plaintiff to fail to require a finding upon that issue in his verdict-directing instruction, unless such error is cured by an instruction submitting that issue on defendant’s behalf. Marsh v. Heerlein, Mo., 299 S.W.2d 441; Lansford v. Southwest Lime Co., Mo., 266 S.W.2d 564. The rule has been criticized as illogical, in that it permits a conflict in instructions where the defendant does submit the issue and plaintiff does not, and also for the reason that the defendant should be held to have abandoned that affirmative defense unless he does choose to submit an instruction upon it. This point is not briefed here, and we do not consider the present case as a suitable vehicle for a reconsideration of the rule. We do, however, note these substantial criticisms of the rule.
In this case we have determined that the issue of plaintiff’s negligence, as made by the defendants, was of direct and proximate cause negligence (at least suggestive of sole cause negligence), and that contributory negligence, as such, was not an issue; in other words, these combatants joined issue on the question of which one was guilty of such negligence, pro or con, as to constitute the direct and proximate cause of the collision; in this, we have construed the amendment to the answers in the light of the instructions given on behalf of the defendants. Defendants’ given instructions refer to plaintiff’s negligence in several places, but never as “contributory” negligence, nor was the word “contributed” so used; thus, plaintiff’s alleged negligence was submitted in Instruction 4 as negligence directly resulting in the collision and thereby requiring verdicts for the defendants both on their counterclaims and on plaintiff’s petition. That instruction did, it is true, negative contributory negligence on the part of the defendants, but that finding could only apply to their counterclaims and the reference could have no direct bearing on the other issues. It would be wholly illogical to say that any live issue of plaintiff’s contributory negligence was raised or tried in this situation, for defendants chose to adopt and submit a different, and broader, theory. Plaintiff’s verdict-directing instruction joined issue with the defendants upon the issue of negligence “directly” causing the injuries; so considered, the instructions are consistent and no live issue was ignored. Under these circumstances we hold that the assigned failure to negative “contributory” negligence did not render the instruction erroneous.
