concurring and dissenting from the majority opinion.
The majority’s dramatic alteration of I.C. § 6-1401 et seq. — Idaho’s Product Liability Reform Act — ignores the plain wording of statutory law, abrogates the legislature’s intent, and usurps the legislature’s functions. On two accounts the majority has seriously erred in holding that it was error on the district court’s part in not allowing the jury to consider the conduct of Kelsey-Hayes and the Coats Company — two non-parties at trial. First, it was the legislature which declared the procedures in determining comparative responsibility in a products liability case, and the evidence at trial dealing with the products manufactured by Kelsey-Hayes and by Coats did qualify for jury consideration. Second, there was not substantial and competent evidence in the record which would have justified the placing of these parties on the verdict form.
I.
The majority relies on two cases, Pocatello Industrial Park Co. v. Steel West, Inc., 101 Idaho 783, 621 P.2d 399 (1980), and Lasselle v. Special Products Co., 106 Idaho 170, 677 P.2d 483 (1983) to support its position. Both the cases are readily distinguishable at the outset; both are negligence cases. The verdict and judgments thereon which we here review resulted from a trial centering around the issue of Uniroyal’s strict products liability. In Lasselle, the most recent of the two decisions, this Court was careful to point out that:
since the plaintiff was awarded damages under the negligence theory, we hold that the trial court erred in not placing D & B Supply Company on a special verdict form because in a negligence action it is imperative that the jury have the opportunity to consider the negligence of all the parties to the transaction. Pocatello Industrial Park, supra.
Id. at 172, 677 P.2d at 485 (emphasis added).
Thus it is seen that Lasselle simply adhered to the precedent of Pocatello Industrial, both negligence cases. But neither Pocatello nor Lasselle are authority for requiring a district court to place nonparties on a special verdict form in a strict products liability case. The district court so ruled. Nor did Uniroyal furnish the Court with any other authority of precedential value in that theretofore unexplored area of the law.
The justification for placing nonparties on a jury verdict in Pocatello Industrial and in Lasselle was couched in the same language:
[Tjrue apportionment cannot be achieved unless that apportionment includes all tortfeasors guilty of causal negligence either causing or contributing to the occurrence in question whether or not they are parties to the case.
Lasselle, 106 Idaho at 172, 677 P.2d at 485, quoting Pocatello, supra, 101 Idaho at 787, 621 P.2d at 403 (emphasis added).
In both cases the Court cited Heft & Heft, Comparative Negligence Manual § 8.131, at 12 (1978), and other comparative negligence cases, but no authority was cited which stemmed from strict products liability cases.
The authority and rationale for comparative negligence in Idaho is a statutory one found in I.C. § 6-802:
The Court may, and when requested by any party shall, direct the jury to find separate special verdicts determining the amount of damages and the percentage of negligence attributable to each party; and the Court shall then reduce the amount of such damages in proportion to the amount of negligence attributable to the person recovering.
Entirely contrary to what Justice Bakes would envision, I.C. § 6-1304, which allows for some comparison of responsibility in products liability actions, reads differently:
Comparative Responsibility — Comparative responsibility shall not bar recovery in an action by any person or his legal representative to recover damages *550for product liability resulting in death or injury to person or property, is such responsibility was not as great as the responsibility of the person against whom recovery is sought, but any damages allowed shall be diminished in the proportion to the amount of responsibility attributable to the person recovering. (Emphasis added.)
The difference is substantial. Under § 6-1304, comparison is of responsibility between the person against whom recovery is sought [the defendant], and the person recovering [the plaintiff].
I.C. § 6-1305, entitled “Conduct Affecting Comparative Responsibility” specifies conduct which can be compared against the defendant’s conduct in a products liability action, specifically, (1) the claimant’s failure to observe an obvious defect, (2) the use of a product with a known defective condition, by either a claimant or a non-claimant, or, (3) the misuse or alteration of a product by either a claimant or a non-claimant, shall subject the claimant’s damages to reduction or apportionment. Such are the statutorily controlling directives in allowing the comparison of responsibilities in products liability actions in Idaho. Thus, in order for the majority to declare in this case that either Kelsey-Hayes or Coats Company comes under one of the categories set out in § 6-1305, it must be able to point to that language in the statutory authority which would have authorized the trial court to allow the jury to assess some degree of comparative responsibility to Kelsey-Hayes or to Coats, for using the defective tire, and/or for misusing and/or altering it. Of course, neither used it, and equally, neither misused it or altered it.
Carefully, and the trial bar may say deviously, the majority avoids applying I.C. §§ 6-1304 and 6-1305. Instead, the majority contentedly writes: “I.C. § 6-1304 ... is substantially identical to I.C. § 6-801 which provides for comparative responsibility in negligence actions. They should be treated the same.” Majority opinion, p. 542, 726 P.2d p. 654 (emphasis added). This may very well be the champion of all ipse dixits. No reason is given for these statements; no authority is supplied to support these assertions. Nowhere is the existence of I.C. § 6-1305 ever mentioned. How the majority can so completely ignore the crucial applicability of the legislature’s statute is beyond belief.
Many courts have considered the impact of concepts of comparative negligence or fault to strict liability actions. The majority cites several decisions which acknowledge that comparative responsibility is an issue in strict liability actions. There is, however, a solid line of authority which hold inapplicable comparative negligence of fault principles in strict liability actions. See Kinard v. Coats Co., 37 Colo.App. 555, 553 P.2d 835, 837 (1976); Melia v. Ford Motor Co., 534 F.2d 795, 802 (8th Cir.1976); Kirkland v. General Motors Corp., 521 P.2d 1353, 1367 (Okla.1974); Roy v. Star Chopper Co., 584 F.2d 1124, 1133 (1st Cir. 1978), cert. denied, 440 U.S. 916, 99 S.Ct. 1234, 59 L.Ed.2d 466 (1979); Smith v. Smith, 278 N.W.2d 155, 160-61 (S.D.1979); Seay v. Chrysler Corp., 93 Wash.2d 319, 609 P.2d 1382, 1384 (1980).
In its detailed examination of the cases discussing the role of comparative fault in product liability actions, the majority simply goes astray. The issue before the Court today is not whether comparative fault, applies in Idaho. The Court judicially adopted it in Shields v. Morton Chemical Co., 95 Idaho 674, 518 P.2d 857 (1974); the Idaho legislature followed suit and occupied the field in 1980 by enacting what the legislature called the Product Liability Reform Act. The question before the house is whose conduct, i.e., the conduct of what individuals and entities, should be considered when addressing the question of comparative responsibility. That question, too, has been answered by the legislature, and the majority would be well advised to commence its analysis by first addressing that which the legislature has said.
For this reason, all of the cases upon which the majority relies are far off point *551in that none of those decisions discuss or interpret comparative responsibility in light of a relevant state statute, let alone one similar to Idaho’s.
The legislature’s Product Liability Reform Act’s system of comparative responsibility is not contrary to any consensus in those cases discussing comparative responsibility under product liability enactments. It represents one of several schemes of comparative responsibility — a public policy choice on the part of the Idaho legislature that it is the best system.2 It should not therefore be so brazenly modified. To do so constitutes judicial activism in its most regrettable form. The trial court’s decision not to include nonparties Coats and Kelsey-Hayes on the special verdict form was correct and should not be so readily reversed, especially to oblige the manufacturer of a dangerously defective tire whose only effort to establish any kind of a case against them fell far short and consisted only of using plaintiff’s expert witness as its own in what most practitioners will see as improper cross-examination. See part VI, infra.
II.
A.
The non-party corporations, Kelsey-Hayes Company and Coats Company, should not have been put on the verdict form for the additional reason that the elements required for any kind of comparative fault assessable to either were not established at trial.
It is the general rule that before nonparties are placed on jury verdict forms there must be a showing that the requisite elements of a cause of action against them must have been presented at trial. There must have been admitted into evidence proof sufficient to make a case in negligence, where applicable, or in strict products liability, where applicable, before any non-party can be included on the form. Lasselle, supra, 106 Idaho at 173, 677 P.2d at 486. For instance, it is beyond dispute that where there is no evidence that a plaintiff was contributorily negligent, where applicable, or comparatively negligent, where applicable, the jury should not be instructed to consider plaintiff’s conduct. See, e.g., Hundt v. LaCrosse Grain Co., 425 N.E.2d 687, 704 (Ind.App.1981); Batten v. Michel, 15 Md.App. 646, 292 A.2d 707, 712 (1972); Gutterman v. Biggs, 249 Md. 421, 240 A.2d 260, 262 (1968); Jennings v. Hodges, 80 S.D. 582, 129 N.W.2d 59, 64 (S.D.1964).
This Court in prior days has recognized as much, and has held that there must he substantial evidence to support the legal theory to justify any instruction on that theory. See, e.g., Johnson v. Clearwater Stage Lines, Inc., 96 Idaho 389, 391, 529 P.2d 1261, 1263 (1974); Edwards v. Walker, 95 Idaho 289, 292, 507 P.2d 486, 489 (1973); McIntire v. Engle, 90 Idaho 63, 66, 408 P.2d 159, 160 (1965); Kuhn v. Dell, 89 Idaho 250, 253, 404 P.2d 357, 358-59 (1965); Schwandt v. Bates, 88 Idaho 131, 133, 397 P.2d 244, 245 (1964).
In this case, there was insufficient proof of any negligence on the part of either Kelsey-Hayes or the Coats Company.3 There is no proof in the transcript as to when the tire mounting machine or the rim were manufactured. Therefore, other than by sheer speculation, it would have been impossible for the jury to determine when the tire mounting machine or the wheel were manufactured. How a jury could decide if either Kelsey-Hayes or Coats Company failed to use ordinary care when it is impossible to know when these machines were designed or manufactured is an unknown. It may very well be that both the tire mounting machine and wheel were manufactured before the first tire bead *552failed. It may equally be the fact that these products were manufactured before it was economically and technologically feasible to make any changes in them. How could the jury in this case have decided that the designers and manufacturers of the tire mounting machine and the wheel were negligent when the record is devoid of evidence establishing when any claimed acts of negligence were performed?
Neither is there any evidence of the knowledge which was available to the manufacturers of these products at the time they were designed and manufactured. What information did these manufacturers have or should they have had regarding any potential hazard of their respective products? Speaking specifically about this situation, some of the questions which went unanswered by the proof are: What information was known or chargeable to the manufacturer of the wheel and the tire machine that Uniroyal tires might explode at all? How much did they know about tire explosions? How much should they have known? Without proper evidence establishing applicable times, the jury would have been unable to answer these questions without indulging in sheer speculation. All that was before the trial court and jury is the statement of Dr. Milner that in his opinion certain corrections could be made in the machines, although he conceded that the manufacturer itself did not agree with him. There is no evidence in the record to establish when the need for these changes became apparent, nor as to feasibility — all of which is a natural product of Uniroyal’s use of plaintiff’s expert.
Idaho has recognized that in proving a case in negligence, the basic test is whether the conduct of the defendant measured up to that of the ordinary prudent person acting under all circumstances and conditions then existing. Alegria v. Payonk, 101 Idaho 617, 619, 619 P.2d 135, 137 (1980); Messmer v. Ker, 96 Idaho 75, 79, 524 P.2d 536, 540 (1974); Nagel v. Hammond, 90 Idaho 96, 102, 408 P.2d 468, 472 (1965). All of these cases state that the actions complained of are to be compared to the ordinarily prudent person’s actions under all circumstances and conditions then existing. In this case, the jury did not know when “then” was. All we have is an expert’s opinion that modifications could be made as of the time of his testimony improved upon the safety of those products. This hardly proves a case of negligence, contrary to the majority’s cavalier assertion. In fact, it does not even rise to the level of a prima facie case, which even in a pure comparative negligence case is essential before the placing of these non-parties on the jury verdict form. A negligence action focuses on the acts of the parties, in which regard it has always been thought necessary to make a case. Whatever the nonparties did or did not do has not been sufficiently developed.
In sum, the trial court correctly perceived that there was not enough proof in the record to justify placing the Coats Company and the Kelsey-Hayes Company on the jury verdict form because of Uniroyal’s contention that each or both were negligent, and such was a contributing cause of the plaintiff’s injuries.
Henderson v. Cominco American Inc., 95 Idaho 690, 700, 518 P.2d 873, 883 (1974), is in total harmony with the foregoing discussion where this Court stated that the party claiming a defective product has the burden of proving by a preponderance of the evidence that the allegedly defective product caused the harm complained of and that the party with the burden in that case — Henderson—had failed his burden of proof, and, therefore, reversed a judgment in his favor.
Henderson involved the acts of parties to the suit. Our case does not. Rather, our case involves a defendant on cross-examination attempting to prove either a negligence or strict products liability cause of action against nonparties to the suit — parties not represented by legal counsel who would by a motion for directed verdict obtain a ruling that the evidence was insufficient. Here we have a majority telling the trial court to conduct another trial on liability with the doors thrown open wide to wild *553speculation as to whether the nonparties should be assessed some fault so that Uniroyal’s responsibility in strict liability will be diminished, a most unsatisfactory and unfair proposition.
As Henderson teaches, the burden was on Uniroyal to prove a cause of action against the nonparties. It did not, and, accordingly, pursuant to Henderson, Uniroyal’s argument for reduction in damages was properly denied on the basis of insufficiency of evidence.
B.
There is also insufficient evidence to prove as comparative fault that either Kelsey-Hayes or the Coats Company were responsible for providing Vannoy’s employer with a defective and unreasonably dangerous product under 402A of the Restatement (Second) of Torts as adopted by Idaho in Shields v. Morton Chemical Co., 95 Idaho 674, 676, 518 P.2d 857, 859 (1974). Section 402A states, in pertinent part, the following:
One who sells any product in a defective condition unreasonably dangerous to the user or consumer or to his property is subject to liability for physical harm thereby caused to the ultimate user or consumer, or to his property____
The important statement relevant to this case is “one who sells any product in a defective condition____” In other words, the defective condition must exist at the time it is sold. There is not a scintilla of proof in this record to establish the time that the wheel and the tire mounting machine were sold to Vannoy’s employer, or that, at the time and the then state of the art, the products were defective. Without that proof, how could a jury find that the product was in a defective condition and unreasonably dangerous at the time it left the hands of the defendant? Thus, any claim of strict products liability against the nonparties, Coats Company and Kelsey-Hayes, must fail, because of failure of proof on an element of products liability law as outlined by Idaho case law — which case law was allowed to stand in 1980 when the legislature decided that it would occupy the field of strict products liability.
III.
The district court, in deciding this issue below, reviewed Pocatello, supra, and Lasselle, supra, and concluded that comparative fault principles are not applicable to strict product liability except as under the legislative guidelines. If the majority is determined to usurp the legislative function, it would more appropriately not apply it to the instant case, but to all cases tried after the filing of its opinion.4 When California adopted comparative fault principles in strict product liability cases in Daly v. General Motors Corp., 20 Cal.3d 725, 144 Cal.Rptr. 380, 575 P.2d 1162 (1978), it stated on page 391, 575 P.2d page 1173:
It remains for us to decide the extent to which comparative principles are to be applied to strict liability actions other than those hereafter filed. We conclude that, for reasons of public policy and the reasonable expectations of the parties to this action and the litigants generally, the principles herein expressed shall apply to all cases in which trial has not begun before the date this opinion becomes final in this Court. No judgment based upon the trial which has commenced prior to the finality of this opinion shall be reversible on appeal on the sole ground that principles of comparative fault were not applied. If any such judgment is reversed on appeal for other reasons, the principles herein expressed will be applicable to any retrial commenced after its opinion becomes final in this Gourt.
In Duncan v. Cessna Aircraft, 665 S.W.2d 414, 434 (1984), a case relied upon heavily by the majority, that court also *554declared that the new rules announced concerning comparative fault in strict liability cases would only have prospective application.
Prospective rulings are not new to Idaho. The Court utilized this principle when it abolished governmental immunity in Smith v. State, 93 Idaho 795, 473 P.2d 937 (1970). In the instant case, the trial court followed the law that was available in both Pocatello and Lasselle, which was that in negligence cases, the jury should have the opportunity to compare the negligence of all parties whether or not they are parties to the lawsuit. The trial court’s fault, if such it be, a monstrous proposition to which I could never subscribe, was in looking at the 1980 legislature’s specific and totally unambiguous language as to what circumstances and conduct of what persons or entities could result in diminishing that which at the outset would be a strict products liability defendants’ 100 percent responsibility for placing a defective product into the mainstream of commerce. The legislature’s enactment is not difficult of reading or ambiguous as to content:
CHAPTER 225
(H.B. No. 577)
AN ACT
RELATING TO PRODUCT LIABILITY; AMENDING TITLE 6, IDAHO CODE, BY THE ADDITION OF A NEW CHAPTER 13, TITLE 6, IDAHO CODE, TO PROVIDE FOR THE SCOPE OF THE ACT, TO PROVIDE DEFINITIONS, TO PROVIDE FOR THE MAXIMUM LENGTH OF TIME PRODUCT SELLERS ARE SUBJECT TO LIABILITY, TO PROVIDE FOR COMPARATIVE RESPONSIBILITY, TO DEFINE CERTAIN CONDUCT AFFECTING COMPARATIVE RESPONSIBILITY, TO PROVIDE STANDARDS OF RELEVANCE FOR CERTAIN EVIDENCE, TO DEFINE INDIVIDUAL RIGHTS AND RESPONSIBILITIES OF PRODUCT SELLERS OTHER THAN MANUFACTURERS, TO PROVIDE FOR THE CONTENTS OF A COMPLAINT AND THE AMOUNT OF RECOVERY, TO PROVIDE A SHORT TITLE; TO PROVIDE SEVERABILITY; AND TO PROVIDE AN EFFECTIVE DATE.
Be It Enacted by the Legislature of the State of Idaho:
SECTION 1. That Title 6, Idaho Code, be, and the same is hereby amended by the addition thereto of a NEW CHAPTER, to be known and designated as Chapter 13, Title 6, Idaho Code, and to read as follows:
CHAPTER 13
PRODUCT LIABILITY
6-1301. SCOPE. The previous existing applicable law of this state on product liability is modified only to the extent set forth in this act.
6-1302. DEFINITIONS. (1) “Product seller” means any person or entity that is engaged in the business of selling products, whether the sale is for resale, or for use or consumption. The term includes a manufacturer, wholesaler, distributor, or retailer of the relevant product. The term also includes a party who is in the business of leasing or bailing such products. The term “product seller” does not include:
(a) A provider of professional services who utilizes or sells products within the legally authorized scope of its professional practice. A nonprofessional provider of services is not included unless the sale or use of a product is the principal part of the transaction, and the essence of the relationship between the seller and purchaser is not the furnishing of judgment, skill, or services;
(b) A commercial seller of used products who resells a product after use by a
consumer or other product user, provided the used product is in essentially the same condition as when it was acquired for resale; and
(c) A finance lessor who is not otherwise a product seller. A “finance lessor” is one who acts in a financial capacity, who is not a manufacturer, wholesaler, distributor, or retailer, and who leases a product without having a reasonable opportunity to inspect and discover defects *555in the product, under a lease arrangement in which the selection, possession, maintenance, and operation of the product are controlled by a person other than the lessor.
(2) “Manufacturer” includes a product seller who designs, produces, makes, fabricates, constructs, or remanufactures the relevant product or component part of a product before its sale to a user or consumer. It includes a product seller or entity not otherwise a manufacturer that holds itself out as a manufacturer. A product seller acting primarily as a wholesaler, distributor, or retailer of a product may be a “manufacturer” but only to the extent that it designs, produces, makes, fabricates, constructs, or remanufactures the product before its sale.
(3) “Product” means any object possessing intrinsic value, capable of delivery either as an assembled whole or as a component part or parts, and produced for introduction into trade or commerce. Human tissue and organs, including human blood and its components, are excluded from this term. The “relevant product” under this chapter is that product, or its component part or parts, which gave rise to the product liability claim.
(4) “Claimant” means a person or entity asserting a product liability claim, including a wrongful death action, and, if the claim is asserted through or on behalf of an estate, the term includes claimant’s decedent. “Claimant” includes any person or entity that suffers harm.
(5) “Reasonably anticipated conduct” means the conduct which would be expected of an ordinary reasonably prudent person who is likely to use the product in the same or similar circumstances.
6-1303. LENGTH OF TIME PRODUCT SELLERS ARE SUBJECT TO LIABILITY.
(1) Useful safe life.
(a) Except as provided in subsection (l)(b) hereof, a product seller shall not be subject to liability to a claimant for harm under this chapter if the product seller proves by a preponderance of the evidence that the harm was caused after the product’s “useful safe life” had expired.
“Useful safe life” begins at the time of delivery of the product and extends for the time during which the product would normally be likely to perform or be stored in a safe manner. For the purposes of this chapter, “time of delivery” means the time of delivery of a product to its first purchaser or lessee who was not engaged in the business of either selling such products or using them as component parts of another product to be sold.
(b) A product seller may be subject to liability for harm caused by a product used beyond its useful safe life to the extent that the product seller has expressly warranted the product for a longer period.
(2) Statute of repose.
(a) Generally. In claims that involve harm caused more than ten (10) years after time of delivery, a presumption arises that the harm was caused after the useful safe life had expired. This presumption may only be rebutted by clear and convincing evidence.
(b) Limitations on statute of repose.
1. If a product seller expressly warrants that its product can be utilized safely for a period longer than ten (10) years, the period of repose, after which the presumption created in subsection (2)(a) hereof arises, shall be extended according to that warranty or promise.
2. The ten (10) year period of repose established in subsection (2)(a) hereof does not apply if the product seller intentionally misrepresents facts about its product, or fraudulently conceals information about it, and that conduct was a substantial cause of the claimant’s harm.
3. Nothing contained in subsection (2) of this section shall affect the right of any person found liable under this chapter to seek and obtain contribution or indemnity from any other person who is responsible for harm under this chapter.
4. The ten (10) year period of repose established in subsection (2)(a) hereof shall not apply if the harm was caused *556by prolonged exposure to a defective product, or if the injury-causing aspect of the product that existed at the time of delivery was not discoverable by an ordinary .reasonably prudent person until more than ten (10) years after the time of delivery, or if the harm, caused within ten (10) years after the time of delivery, did not manifest itself until after that time.
(3) Statute of limitation. No claim under this chapter may be brought more than two (2) years from the time the cause of action accrued as defined in section 5-219, Idaho Code.
6-1304. COMPARATIVE RESPONSIBILITY. Comparative responsibility shall not bar recovery in an action by any person or his legal representative to recover damages for product liability resulting in death or injury to person or property, if such responsibility was not as great as the responsibility of the person against whom recovery 'is sought, but any damages allowed shall be diminished in the proportion to the amount of responsibility attributable to the person recovering.
6-1305. CONDUCT AFFECTING COMPARATIVE RESPONSIBILITY. (1) Failure to discover a defective condition.
(a) Claimant’s failure to inspect. A claimant is not required to have inspected the product for a defective condition. Failure to have done so does not render the claimant responsible for the harm caused or reduce the claimant’s damages.
(b) Claimant’s failure to observe an obvious defective condition. When the product seller proves by a preponderance of the evidence that the claimant, while using the product, was injured by a defective condition that would have been obvious to an ordinary reasonably prudent person, the claimant’s damages shall be subject to reduction.
(c) A nonclaimant’s failure to inspect for defects or to observe an obvious defective condition. A nonclaimant’s failure to inspect for a defective condition or to observe a defective condition that would have been obvious to an ordinary reasonably prudent person, shall not reduce claimant’s damages.
(2) Use of a product with a known defective condition.
(a) By a claimant. When the product seller proves, by a preponderance of the evidence, that the claimant knew about the product’s defective condition, and voluntarily used the product or voluntarily assumed the risk of harm from the product, the claimant’s damages shall be subject to reduction to the extent that the claimant did not act as an ordinary reasonably prudent person under the circumstances.
(b) By a nonclaimant product user. If the product seller proves by a preponderance of the evidence that a product user, other than the claimant, knew about a product’s defective condition, but voluntarily and unreasonably used or stored the product and thereby proximately caused claimant’s harm, the claimant’s damages shall be subject to apportionment.
(3) Misuse of a product.
(a) “Misuse” occurs when the product user does not act in a manner that would be expected of an ordinary reasonably prudent person who is likely to use the product in the same or similar circumstances.
(b) When the product seller proves, by a preponderance of the evidence, that product misuse by a claimant, or by a party other than the claimant or the product seller has proximately caused the claimant’s harm, the claimant’s damages shall be subject to reduction or apportionment to the extent that the misuse was a proximate cause of the harm.
(4) Alteration or modification of a product.
(a) “Alteration or modification” occurs when a person or entity other than the product seller changes the design, construction, or formula of the product, or changes or removes warnings or instructions that accompanied or were displayed on the product. “Alteration or modification” of a product includes the failure to *557observe routine care and maintenance, but does not include ordinary wear and tear.
(b) When the product seller proves, by a preponderance of the evidence, that an alteration or modification of the product by the claimant, or by a party other than the claimant or the product seller has proximately caused the claimant’s harm, the claimant’s damages shall be subject to reduction or apportionment to the extent that the alteration or modification was a proximate cause of the harm.
This subsection shall not be applicable if:
1. The alteration or modification was in accord with the product seller’s instructions or specifications;
2. The alteration or modification was made with the express or implied consent of the product seller; or
3. The alteration or modification was reasonably anticipated conduct, and the product was defective because of the product seller's failure to provide adequate warnings or instructions with respect to the alteration or modification.
6-1306. RELEVANCE OF INDUSTRY CUSTOM, SAFETY OR PERFORMANCE STANDARDS, AND TECHNOLOGICAL FEASIBILITY. (1) Evidence of changes in (a) a product’s design, (b) warnings or instructions concerning the product, (c) technological feasibility, (d) “state of the art,” or (e) the custom of the product seller’s industry or business, occurring after the product was manufactured and delivered to its first purchaser or lessee who was not engaged in the business of either selling such products or using them as component parts of another product to be sold, is not admissible for the purpose of proving that the product was defective in design or that a warning or instruction should have accompanied the product at the time of manufacture. The provisions of this section shall not relieve the product seller of any duty to warn of known defects discovered after the product was designed and manufactured.
(2)If the court finds outside the presence of a jury that the probative value of such evidence substantially outweighs its prejudicial effect and that there is not other proof available, this evidence may be admitted for other relevant purposes, including but not limited to proving ownership or control, or impeachment.
(3) For purposes of this section, “custom” refers to the practices followed by an ordinary product seller in the product seller’s industry or business.
(4) For purposes of this section, “technological feasibility” means the technological, mechanical and scientific knowledge relating to product safety that was reasonably feasible for use, in light of economic practicality, at the time of manufacture.
6-1307. INDIVIDUAL RIGHTS AND RESPONSIBILITIES OF PRODUCT SELLERS OTHER THAN MANUFACTURERS. (1) In the absence of express warranties to the contrary, product sellers other than manufacturers shall not be subject to liability in circumstances where they do not have a reasonable opportunity to inspect the product in a manner which would or should, in the exercise of reasonable care, reveal the existence of the defective condition which is in issue; or where the product seller acquires the product in a sealed package or container and sells the product in the same sealed package or container. The liability limitation of this subsection shall not apply if:
(a) The product seller had knowledge or reason to know of the defect in the product;
(b) The product seller altered, modified, or installed the product, and such alteration, modification or installation was a substantial proximate cause of the incident giving rise to the action, was not authorized or requested by the manufacturer and was not performed in compliance with the directions or specifications of the manufacturer;
(c) The product seller provided the plans or specifications for the manufacturer or preparation of the product and such plans or specifications were a substantial cause of the product’s alleged defect.
*558(d) The product seller is a wholly-owned subsidiary of the manufacturer, or the manufacturer is a wholly-owned subsidiary of the product seller.
(e) The product seller sold the product after the expiration date placed on the product or its package by the manufacturer.
(2) In an action where the liability limitation of subsection (1) applies, any manufacturer who refuses to accept a tender of defense from the product seller, shall indemnify the product seller for reasonable attorney’s fees and costs incurred by the product seller in defending such action.
(3) In any product liability action, the manufacturer of the product shall be indemnified by the product seller of the product for any judgment rendered against the manufacturer and shall also be reimbursed for reasonable attorney’s fees and costs incurred in defending such action:
(a) If the product seller provided the plans or specifications for the manufacture or preparation of the product;
(b) If such plans or specifications were a substantial cause of the product’s alleged defect; and
(c) If the product was manufactured in compliance with and according to the plans or specifications of the seller.
The provisions of this subsection shall not apply if the manufacturer had knowledge or with the exercise of reasonable and diligent care should have had knowledge of the defect in the product.
(4) A product seller, other than a manufacturer, is also subject to the liability of manufacturer if:
(a) The manufacturer is not subject to service of process under the laws of the claimant’s domicile; or
(b) The manufacturer has been judicially declared insolvent in that the manufacturer is unable to pay its debts as they become due in the ordinary course of business; or
(c) The court outside the presence of a jury determines that it is highly probable that the claimant would be unable to enforce a judgment against the product manufacturer.
6-1308. CONTENTS OF COMPLAINT-AMOUNT OF RECOVERY. In any product liability action no dollar amount or figure shall be included in the complaint. The complaint shall pray for such damages as are reasonable in the premises. The complaint shall include a statement reciting that the jurisdictional amount established for filing the action is satisfied.
6-1309. SHORT TITLE. This act shall be known and may be cited as the “Idaho Product Liability Reform Act.”
SECTION 2. The provisions of this act are hereby declared to be severable and if any provision of this act or the application of such provision to any person or circumstance is declared invalid for any reason, such declaration shall not affect the validity of remaining portions of this act.
SECTION 3. This act shall be effective with regard to all product liability actions filed on or after July 1, 1980.
Approved March 28, 1980.
1980 Idaho Sess. Laws, ch. 255.
My purpose in displaying the entire 1980 Products Liability Reform Act is to demonstrate the extent to which the legislature determined to, and did, occupy the field. It was only a “reform” act in that it did entirely occupy the field which theretofore had been entered only by this Court. Finding nothing amiss in the U.S. District Court’s decision in Sun Valley Airlines or in this Court’s decision in Shields, by § 6-1301 it specified that “The previous existing applicable law of this state on products liability is modified only to the extent set forth in this act.” Section 6-1304 is important. There, just as the legislature had earlier done in 1971 in the negligence field, it declared that comparative responsibility, as it had with comparative negligence, would not bar a plaintiffs’ recovery until and unless it matched or exceeded the responsibility of the person against whom recovery is sought. There is or should be no problem in this case about the applicabil*559ity of § 6-1304, which would compare plaintiff’s comparative responsibility with Uniroyal’s.
Similarly, there is, or should be, no problem with § 6-1305, (1) failure to inspect; or with (2) use of a product with a known defect. Moving down to (3) of § 6-1305, misuse of a product, there was no evidence here of any misuse of the Uniroyal tire, either by the plaintiff, “the product user,” or by a party other than the claimant or the product seller. Concededly, had such been established, plaintiff’s damages were “subject to reduction or apportionment to the extent that the misuse was a proximate cause of the harm.” There is no contention that (4) of § 6-1305 has any applicability. If it did, and alteration were proven, again plaintiff’s recovery could have been reduced or apportioned “to the extent that the alteration or modification was a proximate cause of the harm.” I.C. § 6-1305(4).
It is thus seen beyond dispute that the legislature has occupied the field, and has set the parameters of those circumstances which can result in a plaintiff’s loss of any recovery, or reduced or apportioned recovery. Five short years later a majority of the Court has determined to amend the act, and are doing so. On other occasions I have observed that at any time under any circumstances, three members of this Court can do anything they want to do. This is such an occasion. But that does not make it right. Right has always been right, and wrong has always been wrong.
IV.
Uniroyal’s opening brief in this Court sets forth how it believes itself to have preserved the comparison issue for appeal: “Uniroyal, in its Motion for New Trial, etc., set forth the failure to compare as an error made by the Court. (R.Vol. I, p. 241). The Court denied the various post trial motions. (R.Vol. I, p. 256).” Appellant’s Brief, p. 26. From there Uniroyal presents quotations and statements from and citations to authority from the courts of Illinois, North Dakota, California, Alaska, Texas, New Hampshire, Oregon, Minnesota, Wisconsin, Kansas, and from various of the federal jurisdictions — following which it makes the assertion that “[a]ll persons or parties contributing to the plaintiff’s injuries in the instant case should have been included on the verdict form.” Appellant’s Brief, p. 39.
Not one whit of that array of authority appears to have been furnished to the trial court, notwithstanding that the motion, although filed on February 24, 1984, was not argued orally until March 27, 1984. The sum total of Uniroyal’s written motion relative to comparison of the nonparties is found in the Record at pp. 245 and 247, the fifth part of its motion for a new trial:
(5) Rule 59(a)(7) — This Honorable Court erred during the course of the trial in the following respects:
(m) In failing to include Kelsey-Hayes Company and The Coats Company on the Special Verdict.
No statement whatever explained or elaborated upon the grounds which would support this specification of error. Yet, I.R. C.P. 59(a) requires that “[a]ny motion based on subdivisions 6 or 7 must set forth the factual grounds with particularity.” This intrinsic requirement of Rule 59(a) has been held mandatory. Conclusory, general and vague language does not suffice. Uniroyal’s wholly conclusory statement that it was entitled to have had the two nonparties on the special verdict form was entirely unsupported by any particularity of the factual grounds. Such failure required that “the motion should have been denied by the trial court.” Scafco Boise, Inc. v. Rigby, 98 Idaho 432, 566 P.2d 381 (1977). In that case the trial judge did not deny the motion, but conditionally granted it unless Scafco would consent to a remittitur. Here, however, it is true that the trial court in denying the motion for a new trial did not specify as a reason the failure to comply with Rule 59(a)’s requirement that under 59(a)(7), the grounds must be stated with factual particularity. The court compassionately allowed Uniroyal a second opportunity at oral argument to *560supply with particularity the grounds which supported its motion, but all, absolutely all, that Uniroyal provided were wholly conclusory remarks — none of which were tied into one bit of testimony or evidence received at trial:
[MR. HIGH:] We would respectfully submit that the Court erred in ... refusing to compare causation between the wheel manufacturer and the tire-mounting machine manufacturer as required under Pocatello Industrial Park vs. [and] Lasselle, evidence was clear there as to the proximate cause of the accident under the trend of law, to compare all causations, and should have been compared in this case.
Furthermore, your Honor, we would submit that the order of dismissal signed by this Court during the trial, with respect to Kelsey-Hayes, required a comparison in that order. It was an order signed February 9. On that basis, your Honor, we would ask that the Court grant one of our three alternative motions.
THE COURT: Mr. Pedersen, you may respond.
MR. PEDERSEN: Well, in the first place we only have to compare negligence if there was proof of negligence, I don’t think any kind of order signed by the Court could alter that fact. There would have to be a showing of negligence, or a showing that the other products were defective, and my first and foremost argument on that statement, it was in chambers, it wasn’t evidence of negligence, how could the jury say that the tire manufacturer — that the tire was manufactured negligently or designed negligently, the jury didn’t even know when it was manufactured or when it was designed. How could the jury find that the wheel was defective, it may have been manufactured before any of these blow-ups, it would be pure speculation to suggest that there was adequate proof ... to establish that there was a causal link between any of these. ...
... [H]ow can they say the other products were the proximate cause, the legal test is not the [sic “their”] proximate cause, it’s whether or not the tire was the proximate cause. They don’t even argue or cite cases, they base it on some sort of superseding, intervening cause, which wouldn’t have any application anyway.
We submit, your Honor, that the defendant has not shown any legal reason in this case why it should be retried.
In another contention, the one he gives the most significance to, is really improper both on a factual basis, no facts in the record, either in chambers nor in his argument today has he addressed the question of how could it be proven that the product was defective at the time of manufacture if there was no proof of the date of manufacture of those products.
Secondly, how could it be proven that the products were defective or negligently designed if there is no proof of what the state of the art was, or whether there was ever even any knowledge of tire blow-ups at the time of manufacture. He has not raised sufficient grounds for judgment n.o.v., new trial.
I’ll finish up by addressing the question on remittitur.
THE COURT: Mr. High, you may respond.
MR. HIGH: No rebuttal, your Honor.
THE COURT: At this time the Court is going to order that the motion for judgment n.o.v. and the motion for new trial will be, in all respects, overruled and denied.
The two best points I think that Mr. High raises, I feel number one, that the evidence does not — just did not justify instructing the jury on any defects in the other products used in the case, other than the Uniroyal tire, and therefore no error in making — no making such an instruction.
Tr., pp. 707-11 (emphasis added). Uniroyal’s effort fell far short of compliance with the rule. The trial court most *561obviously was not, either in the written motion, or an oral argument on the motion, provided with any factual particularity at all, and for certain not with any which convinced him that out of whole cloth he should expand the 1980 Products Liability Reform Act so as to include on a special verdict nonparties whose conduct did not come within the legislative purview of what type of conduct, and by what parties, could dimmish “the heightened duty and liability of the manufacturer of a defective product.”
Y.
Uniroyal in its reply brief makes an interesting concession as to that array of authority set out in its opening brief — a concession which one would think would have caught the eyes of Justice Bakes in the writing of his opinion:
Plaintiff was correct in reporting that Uniroyal has cited this Court no authority wherein a non-party was compared in a products liability action.
Appellant’s Reply Brief, p. 15.
Uniroyal’s sole response to this:- “Conversely, neither has Plaintiff cited the Court to such a case where a comparison was not permitted.” Appellant’s Reply Brief, p. 15. Putting aside that Judge Meehl’s decision in this case is one recent holding on the exact issue, it would hardly seem that Uniroyal would expect to carry the day, i.e., of persuading an appellate court that, in that state of precedential equipoise, the trial court was clearly in error. Moreover, although not apparently troubling the majority who agree on the opinion for the Court, it would seem that any party in presenting post-judgment motions should not be allowed to use a scatter-gun unsupported by any authority and then scurry into the appellate clamoring out against the error in the trial court’s decision. Recollection tells me that one member of this Court has decried such conduct as sandbagging the trial court — a practice to be discouraged, if for no other reason than because it is judicially inefficient. One would like to think that on appeal the reviewing court is examining not only the same record which was before the trial court, but for the most part, at least, also the same authority and arguments. Returning to page 15 of the Uniroyal reply brief, after its assertion that Vannoy’s authority is no more on point than Uniroyal’s, Uniroyal apparently claims one-upmanship in that:
Uniroyal has, however, cited this Court to numerous cases where comparisons were made between defendants, some of who were product manufacturers. See: Wilson v. B.F. Goodrich, [292 Or. 626], 642 P.2d 644 (Or.1982) and Busch v. Busch Construction, Inc., supra.
Appellant’s Reply Brief, p. 15 (emphasis added).
The point of this thrust escapes me. Defendants, per se, by nomenclature, are parties. Sometimes the plaintiff may name more than one party defendant. If plaintiff names only one defendant, that defendant may implead yet another person who becomes party to the action. And where plaintiff names two or more defendants, each of those defendants can implead other party defendants, and so on. Such third-party defendants practice may be pursued in order to place the blame elsewhere. In California, a plaintiff who has not named as his own defendant a third-party defendant later brought in by a defendant can (probably after discovery has proven helpful) accept that third-party defendant as a plaintiff’s defendant. All of which is not to attempt a lecture on third-party practice, but to set the stage for some observations which to my mind are highly pertinent to our review on appeal.
The complaint in this case was filed in September of 1982. The complaint named as defendants: (1) Uniroyal, (2) Kelsey-Hayes Company (wheel manufacturer), (3) Hennessey Industries, The Coats Company (manufacturer of the tire-mounting machine), (4) The Tire and Rim Association, Inc., and (5) Terry Brennan. Count Two of the complaint was founded on strict products liability. Trial did not commence until February of 1984. Uniroyal’s answer to the complaint was filed in November of *5621982. “Uniroyal denied the claims of Vannoy, alleging that the accident was proximately caused by the combined conduct of Vannoy, the Kelsey-Hayes Corporation and/or Hennessey Industries/The Coats Company.” Uniroyal’s opening brief, p. 1. Uniroyal was the first of the pleaded defendants to answer the complaint.
It did allege as the first of six affirmative defenses that plaintiff’s injuries were chargeable to the acts or omissions of the other named defendants: (1) the Coats Company, a division of Hennessey Industries, (2) Kelsey-Hayes Company, (3) the Tire and Rim Association, Inc., and (4) Terry Brennan.5
Inexplicably, Uniroyal chose not to follow up on its allegations alleging that the other defendants were all the responsible parties for plaintiff’s injuries by filing a cross-action against them claiming contribution or indemnity. Obviously, so it would seem, had Uniroyal done so, it would have kept both The Coats Company and Kelsey-Hayes in the law suit notwithstanding plaintiff’s settlement with each, followed by plaintiff’s dismissal. How Uniroyal intended to prove its allegations against those defendants is unknown. What is known, however, that when those two defendants were dismissed prior to trial, Uniroyal’s only effort in the direction of proving the allegations of its first affirmative defense was to make use of its cross-examination of Dr. Milner, plaintiff’s expert witness, to attempt to establish enough causative fault on the part of those two defendants.
When plaintiff’s case went to the jury on a charge of Uniroyal’s strict products liability only, the theory of negligence having been dropped, whatever Uniroyal had developed by using Dr. Milner as its own witness was wholly insufficient to have warranted the jury being allowed to consider Uniroyal’s allegations that The Coats Company and Kelsey-Hayes were responsible in any part for the explosion of the Uniroyal tire. And, as I have been at pains to point out, Uniroyal did not in its post-judgment motions or in arguing these motions, ever lay before the trial court with particularity the factual background with which it would persuade the trial court that it was in error.
Moreover, where Uniroyal, in charging Kelsey-Hayes and The Coats Company with the conduct which injured Vannoy did not choose to name them as third-party defendants, it also thusly eschewed the opportunity of keeping them in court so that, at least as between all defendants originally named, the jury could, perhaps, apportion for later purposes of contribution or indemnity. Instead, Uniroyal, having failed in every respect, comes to this Court to argue, FOR THE FIRST TIME, that which it never argued to the trial court — either the law or the facts. Luckily for it, and boding ill for the science of jurisprudence in Idaho, it has found a Court which will at one fell swoop amend the recent law of the legislature, and decide the issues in accordance therewith.
VI.
Beginning at page 39 of Uniroyal’s opening brief filed in this Court, Uniroyal contends: “The evidence of the wheel and tire mounting machines contribution to the cause of Plaintiffs’ injuries was provided by Plaintiffs’ own expert, Dr. Alan Milner.” Dr. Milner was indeed called as an expert witness on plaintiff’s case. Uniroyal’s counsel on cross-examination of Dr. Milner was successful in its attempt to steal and use him as its only witness in an effort to establish some kind of contributing fault or conduct attributable to the two non-parties who had constructed the tire-changing machine and built the I6V2 rim (wheel). Re*563turning to Uniroyal’s brief, page 39, the argument, with citations, goes thusly:
Dr. Milner identified the mountain machine used in this case as a Coats 30-30. (Tr. Vol. II, p. 339, L. 3-12). Dr. Milner further testified that the machine contributed to the accident. (Tr. Vol. II, p. 339, L. 23). It contributed to the accident because it acted as “launching pad.” (Tr. Vol. II, p. 340, L. 3). It also lacked a pressure line regulator. (Tr. Vol. II, p. 341, L. 16). The machine was further defective because it lacked an overpressurization alert system. (Tr. Vol. II, p. 343, L. 3). Finally, Dr. Milner testified that the machine was a contributing cause of the accident. (Tr. Vol. II, p. 349, L. 1).
Turning from the brief to the cited pages of Volume II of the transcript (339, 340, 341, 343, 349):
CROSS-EXAMINATION
BY MR. HIGH:
Q. Dr. Milner, did you ever determine what type of mounting machine was used to mount this tire on this rim?
A. Yes, a Coates machine.
Q. Was it a Coates 30-30 machine?
A. I believe it was. Mr. Pedersen has photographs of it.
Q. And you believe, do you not Dr. Milner, that the Coates 30-30 machine contributed to the accident, don’t you?
A. Well, let me say this about that, the testimony I heard about the involvement of the machine is somewhat in conflict. There is testimony [the tire] was on the machine at the time of the explosion, and in the sense if it’s on the machine at the time of the explosion, it contributes to the accident in the same sense that the floor contributes to the accident, because the Coates machine and other machines like it have a flat surface from which the tire can be projected, so it contributes in that sense, if it’s sitting on the machine.
Q. Assuming that Mr. Vannoy testifies it was on the machine, in your opinion the Coates machine contributed to the accident, correct?
Tr., Vol. II, p. 339 (emphasis added).
A. In that sense, yes. This is always the case with a machine like that.
Q. Because it’s a launching pad?
A. Yes, they all have—
Q. Don’t you also believe, Dr. Milner, that the lack of a pressure-line regulator on a Coates 30-30 machine contributed to the explosion?
A. Well, it does in cases where there is overpressurization of it, but in this case, as I recall, there was not.
Q. Sixty pounds is not over-pressurization?
A. It has to be sixty pounds in order to inflate — in order to inflate to sixty-five pounds there has to be sixty pounds, you could not regulate the level down below that and have enough air to put in the tire.
Q. Dr. Milner, don’t you believe, though, that these machines, these Coates 30-30 machines, are defective, because they have no pressure-line regulator that limits pressure to forty pounds?
MR. PEDERSEN: Excuse me, I’ll have to object to this line of questioning as not within the scope of direct examination.
Tr., Vol. II, p. 340 (emphasis added).
THE COURT: The Court is going to overrule the objection. You may answer the question.
THE WITNESS: Would you restate the question, please.
Q. The question was: Don’t you believe that the lack of a pressure-line regulator on the Coates machine was a contributing cause to the accident?
A. I think it’s a contributing cause if it’s overpressurization, but not to forty pounds, because if you have only forty pounds — let me tell you what I have said, when I’ve been asked, I think—
*564MR. HIGH: Just answer the question.
THE WITNESS: I can’t answer your question.
MR. PEDERSEN: Your Honor, he needs an opportunity to answer the question.
THE COURT: I’m going to indicate that you’ve answered the question. The answer was not overpressurization, so the Court is going to allow that answer to remain.
Tr., Vol. II, p. 342 (emphasis added).
Q. Do you believe there should be an alert system?
A. I believe that there should be a double position pedal, which would introduce the air, and when the air is above a pre-determined figure, and 40 would be as good a figure as any, although it wouldn’t necessarily preclude the accidents, there should be some audible signal that more than that pressure is there, because in passenger tire cases, this can be most of the tires mounted on machines, they are passenger tires, not sixty-five pound tires.
Q. And this machine does not have such a system?
A. No.
Q. You believe that’s a defect in these machines?
A. I believe all these machines could be improved.
Tr., Vol. II, p. 343 (emphasis added).
Q. Then on the next page [of a deposition handed to the witness], page 45, you were asked “Q. In that case is it your opinion that the Coates tire machine was a contributing cause of this accident?”
“A. Yes. Certainly I think I testified to that.” Is that not what it states in there?
A. Yes, that’s correct.
Tr., Vol. II, p. 349.
So much for Uniroyal’s proof of causal fault on the part of the tire-changer. Its brief then contends, on p. 40, that:
Dr. Milner also provided testimony with respect to the wheel involved in this case. In direct examination he described the “anomaly in the design” of the 16.5 inch wheel which permitted a 16 inch tire to be introduced. (Tr. Vol. II, p. 272, L. 1). Dr. Milner, on cross-examination, admitted that the basic problem of a mismatch of a 16 inch tire to a 16.5 inch wheel was the initial inability of the tire being able to fit over the anomaly of design of the wheel, and the wheels visual similarity to a proper sized wheel. (Tr. Vol. II, p. 356, L. 1). It was the design of the wheel which set the precondition of the explosion, or in other words, was the “the fuse on the bomb.” (Tr. Vol. II, p. 356, L. 6). He testified that the wheel should be configured so that it would not accept a 16 inch tire. (Tr. Vol. II, p. 357, L. 1). He described the ability to mount as an “internal defect” of the wheel. (Tr. Vol. II, p. 357, L. 22). Finally, Dr. Milner testified that the wheel lacked an alert system and was improperly marked. (Tr. Vol. II, p. 359, L. 19).
Turning to the cited pages of the transcript (272, 356, 357, 359):
[ON DIRECT]:
A. You are referring to the reason why it [the tire being mounted] might hang up?
Q. Yes.
A. Well, there are two general circumstances in which this occurs. Most of them, the vast majority of explosions occurs, for instance, when a 14-inch tire is on a 14-inch wheel, or a 13-inch wheel, or a 16-inch — but there is an anomalous situation that can arise in which there are two kinds of wheels, one which belongs to a different family than the other. There is the so-called 15 degree wheel, which was the wheel in question in this accident, and these are somewhat different in design than other wheels, although they appear almost identical, *565and it’s possible in some of these cases for the 16-inch type to inadvertently be introduced onto a 16.5 wheel. The reason for that, the 16.5 wheels are slightly larger than the 16-inch wheels, some anomaly in the design, the flange diameter it has to go over is actually larger in the small sized wheels, this pressure to pull these tires onto the 16.5, and inadvertently creates a situation which is one of the causes of this kind of situation.
Q. Let me stop you there to make sure we all understand something that may be confusing.
Q. Which is the larger wheel, the 16.5 wheel or the 16-inch wheel?
A. In terms of over-all diameter, the amount of diameter here, which the tire has to go over, the 16.5 is actually slightly smaller in this diameter than is a 16, and I think it’s usually about three sixty-fourths of an inch, just a little bit.
Tr., Vol. II, p. 272 (emphasis added). [ON CROSS:]
Q. The basic problem of a mis-match of a 16-inch tire to a sixteen and a half inch wheel is the initial ability with which the tire can be mounted on the wheel, is that right?
A. Yes, that combined with the visual similarity.
Q. In fact don’t you refer to that, this low circumference, lesser circumference of the sixteen and a half inch wheel as, “the fuse on the bomb”?
A. It is in some circumstances, it sets up a situation where you can have a hangup.
Q. Don’t you believe it’s “the fuse on the bomb”?
A. I don't know if I've used that language, but you could. It sets the precondition for a hangup, although not necessarily for an explosion.
Q. The design of the wheel sets that up, that pre-condition?
A. The pre-condition for the hangup, yes.
Q. It’s the ability, the ease, and if that’s easier, if it’s smaller, to put a 16-inch tire on a sixteen and a half inch wheel than to put it on a 16-inch wheel—
A. I don’t think it’s necessarily easier. You’ve got to consider the depth of the drop center, and in my experience it’s been indistinguishable, the difference, I’ve not found it easier, or more difficult.
Q. Don’t you believe that if you’re going to have
Tr., Vol. II, p. 356 (emphasis added), a 16-inch tire, the wheel should be configured in such a way that you can’t put a 16-inch tire on a sixteen and a half inch wheel?
A. I think it should, yes. I think that kind of wheel should be precluded, the mounting of the 16-inch tire, I think it should be so designed—
Q. This wheel doesn’t, does it?
A. No.
Q. Who makes this wheel?
A. Kelsey-Hayes, I think.
Q. If this wheel were modified marginally, by Kelsey-Hayes, this 16-inch tire wouldn’t go on it—
A. Are you telling me or asking me?
Q. Would it, if it were modified, if it was marginally modified?
A. Well, I think that if — I can perceive of ways in which the wheel could be modified to preclude the introduction of a 16-inch tire on it. The manufacturer of it says it cannot.
Q. But you can?
A. I have not done it, but I don’t see any reason—
Q. You believe that’s an internal defect of this thing, this wheel?
A. I think it is, yes.
Tr., Vol. II, p. 357 (emphasis added).
Q. You believe, Dr. Milner, that if you’re going to have a sixteen and a half inch wheel, that it should be identified by some type of paint scheme?
*566A. I think it should. There should be some way to visually distinguish it. I think I’ve said in the past that a wheel like that should have some distinguishing thing that ought to be developed to alert people to it.
Q. At the minimum it should have some type of — well, it should have the size marked on it properly is that correct?
A. The size on it is inadequately marked.
Q. There should be some kind of alert that it’s a sixteen and a half inch, don’t put a 16-inch tire on it, correct?
Tr., Yol. II, p. 359 (emphasis added).
A. Well, I wouldn’t say that, because I don’t think you should write the word “sixteen” on it.
Q. You should have some—
A. I don’t think that’s a good idea at all, a person seeing sixteen — that has got to go into it.
Q. But some type of an alert should be on it?
A. I would think so, yes.
Tr., Vol. II, p. 360 (emphasis added).
So that there will be no doubt, let it be clearly understood that the foregoing exercise is exactly the testimony which Uniroyal relied upon in its brief, pages 39 and 40, to support its contention that the trial court should have allowed the jury to consider the comparative responsibility of the two nonparties, and which the majority now rules was that sufficient that “the jury would have been entirely justified in allocating to the mounting machine manufactured by Coats, and to the wheel rim manufactured by Kelsey-Hayes, some or all of the responsibility for proximately causing the damages to the plaintiffs.” Once again I much fear that I find myself in the wrong profession. It is frightening to know that Justice Bakes has written that statement for the majority after making a review of the evidence. That “review of the evidence” bears a startling similarity to that which I have above extracted from plaintiff’s brief.
It will be for the reader to determine for him or herself whether Uniroyal’s capsulized version of the testimony can withstand the scrutiny of an actual examination of the questions put to Dr. Milner and his answers.
Justice Bakes declares for the majority that the testimony of Dr. Milner, as per Justice Bakes’ recitation of that testimony, “was much more extensive than the evidence in Fouche v. Chrysler Motors Corp., 107 Idaho 701, 692 P.2d 345 (1984).” I disagree on three counts. First, I have read Dr. Milner’s testimony and agree wholeheartedly with the trial court’s view that it was not sufficient to make a case. Second, there was not in this trial any procedure which allows for moving for a directed verdict by a nonparty. In Fouche the defendant did so, and the plaintiff’s evidence with all inferences had to be viewed in his favor. Third, Fouche was not based upon expert testimony, but testimony of an actual demonstration prior to purchase of the vehicle and physical evidence that Fouche did in fact smash into the steering wheel and the windshield. It simply is impossible to accept the contentions Justice Bakes has advanced.
Even less acceptable, however, is the highly questionable and I believe dangerous statement that “in determining comparative responsibility or comparative causation it is not necessary to establish that all persons included on the verdict form would be liable for some or all of the damages attributable to their conduct or product.” Sheer surmise on my part, I assume that the Justice is confusing liability and responsibility. In special verdict practice, the jury fixes percentages of causative fault or causative responsibility. To the court falls the task of entering a proper judgment where considered are such factors as immunity, caps on liability, and settlements. Frankly, I am unable to understand the drift of his argument, but it has nothing to do with Vannoy’s contention that an insufficient case of negligence or strict products liability was made out by Uniroyal in its (mis)use of Vannoy’s expert witness.
*567VII.
Justice Bakes seemingly believes that the United States District Court’s opinion in Sun Valley Airlines, Inc. v. Avco-Lycoming Corp., 411 F.Supp. 598 (1976), sustains his own view of how the legislature’s 1980 Reform Act should be read and understood, and, perhaps why it should be judicially amended at Uniroyal’s behest. That action appears to have been initially filed by Sun Valley Airlines against corporation defendants, Avco-Lycoming and Beech Aircraft Corp. Idaho heirs of the five persons killed in the crash also either initiated separate actions or intervened. The title of the action reflects four separate civil actions which were presumably consolidated. The federal court in its hearing a diversity case did not have the benefit of any Idaho statutory law or of any appeal-developed Idaho case law dealing with the ramifications of apportionment of comparative responsibility under strict products liability, the theory of case upon which the claims went to trial.6 Observing that the contention made on post-trial motions was that “comparative causation ... was applied in derogation of the law of Idaho,” 411 F.Supp. at 602, the district court then proceeded to outline in succinct but ample language its 1976 views which later, in 1980, appeared to have been accepted when the Idaho legislature entered the field of strict products liability. The United States district court wrote as follows:
A concept fundamental in tort law is that in order for liability to lie, there must be a wrongdoer whose actions violate a duty owed to a plaintiff. A violation of a duty owed, whether it be labeled negligence or strict liability, is blameworthy or culpable conduct. With the advent of strict products liability, a heightened standard or duty was imposed upon a manufacturer, such that liability results from a defective product which proximately causes injury, even though the manufacturer was not negligent. However, strict liability is not absolute liability because a manufacturer is not an insurer or guarantor that no one will be injured in using his product. The manufacturer is under a duty to produce a product which is free from unreasonably dangerous conditions. A violation of that duty constitutes blameworthiness or culpability or sense of legal fault.
Together with the heightening of a manufacturer’s duty, a modification occurs with regard to a manufacturer’s defenses in a strict products liability action. A plaintiff’s contributory negligence by that label is not a bar to recovery. Nevertheless, it is well-settled that misuse of a product in a manner unforeseeable to a manufacturer is a defense to strict products liability. The misuse defense embodies a policy that a manufacturer should not absorb the consequences of a plaintiff’s misuse of a product in a way which the manufacturer could not reasonably anticipate.
411 F.Supp. at 602 (emphasis added) (footnotes omitted).
The italicized sentence was based on a statement from this Court's opinion in Shields v. Morton Chemical Co., 95 Idaho 674, 518 P.2d 857 (1974), wherein the Court membership was unanimous in judicially adopting the doctrine of strict liability for Idaho. In Sun Valley Airlines, the District Court after observing, as the jury had specifically found, that Sun Valley Airlines, through its employees Smith and Carlton, had misused the aircraft in a manner unforeseeable to the defendant manufacturers, stated that “the jury in this case was asked, consistent with Idaho [existing statutory comparative negligence law] to assign a percentage to the causative conduct of the parties to this lawsuit.” 411 F.Supp. at 603 (emphasis added). In that case the Court dealt with no individual or corporate entity who or which was not a part to the lawsuit.
As indicated by footnote 7, the district court relied upon Dippel v. Sciano, 37 *568Wis.2d 443, 155 N.W.2d 55 (1967), for the statement that “strict liability, like negligence per se, is equally capable of causal comparison.” What the Wisconsin Supreme Court actually said was:
Strict .liability in tort for the sale of a defective product unreasonably dangerous to an intended user or consumer now arises in this state by virtue of a decision of this court. If this same liability were imposed for violation of a statute it is difficult to perceive why we would not consider it negligence per se for the purpose of applying the comparative negligence statute just as we have done so many times in other cases involving the so-called “safety statutes.” Under the definition of negligence per se set forth in Osborne [v. Montgomery, 203 Wis. 223, 234 N.W. 372 (1931) ], supra, a safety rule can trace its origin to a court decision as well as a statute. The violation of a safety statute can create a condition that constitutes an unreasonable risk of harm to others. If this unreasonable danger is a cause, a substantial factor, in producing the injury complained of, it can be compared with the causal contributory negligence of the plaintiff. While this discussion of contributory negligence, assumption of risk and comparative negligence may be obiter dicta because those issues are not before us on this appeal,____
Dippel, 155 N.W.2d at 64-65 (emphasis added).
The Wisconsin court is seen, then, as judicially adopting the doctrine of strict liability, patterned after § 402A Restatement, just as this Court would do seven years later in Shields. Since 1967 strict liability has remained wholly a judicial doctrine in Wisconsin. The legislature has not entered and has not occupied the field. In Idaho the converse has been true since the passage of the Product Liability Reform Act of 1980. Had the Idaho legislature acted prior to the trial of Sun Valley Airlines, the United States District Court would have looked to the legislature’s law — not to Dippel. Moreover, in my opinion, the United States District Court would not have read into the 1980 act language which the legislature did not choose to insert.
. In recent times, I have believed myself being educated to the philosophy that public policy is never a proper concern for the courts, even in an area where the legislature has not yet spoken.
. See Part B, infra, discussing the insufficiency of evidence as it relates to any strict liability claim against either the Kelsey-Hayes Company or the Coats Company.
. In that manner the majority would decide the issues presented on the law as it existed at the time of trial — -just as the trial court did. In that manner an activist majority would retain some small degree of credibility. Rather than apply the law, however, the majority chooses to make new law.
. Not admitting any liability, Uniroyal’s second affirmative defense alleged negligence on the party of Jerry Vannoy and that "his negligence was as great, or greater than, any alleged negligence of this answering defendant [Uniroyal].” Other affirmative defenses alleged Vannoy’s assumption of the risk, his misuse of the various products (the tire, the rim, the mounting machine) manufactured by the defendants, which misuse was the cause of the injuries and damages.
. In answering special verdict question Nos. 6 and 7, the jury found that the Beech aircraft was defective, and that defect was a cause of the crash.
