Schaeffer v. General Motors Corp.
372 Mass. 171 (1977)
360 N.E.2d 1062
The plaintiff was seriously injured on August 12, 1964, when his 1963 Cadillac automobile crossed *172 the median strip of the Massachusetts Turnpike and collided with an oncoming car. The Cadillac, manufactured by the defendant, was equipped with an optional item known as a controlled differential. According to the owner's manual which accompanied the plaintiff's automobile, this device "always directs the major driving force to the wheel having the greater traction. The Controlled Differential makes driving safer and more economical by providing additional traction in snow, ice, mud, sand and gravel, particularly when one rear wheel is on a surface providing poor traction. During normal driving and cornering, the controlled unit functions as a standard differential. When one wheel encounters a slippery surface, however, the Controlled Differential allows the wheel with the greater traction to drive the car."
The jury returned a verdict for the defendant. The *173 plaintiff appealed to the Appeals Court after his motion for a new trial was denied, and we transferred the case here on our own motion for direct appellate review. G.L.c. 211A, § 10 (A). We reverse.
2. Although there was not sufficient evidence to submit the case to the jury on the issue of negligent design, manufacture, or inspection, there was considerable evidence tending to prove that the defendant had a duty to warn purchasers that the differential might reduce safety and stability in certain road conditions. Indeed, the arguments and expert testimony which the plaintiff presented on the issues of negligent design, manufacture, and inspection rested fundamentally on an alleged violation of the duty to warn. The fact that these side effects could not have been eliminated through improved design, manufacture, or inspection does not relieve the defendant of the duty to warn of their existence. This duty has been described as *174 "that of warning of the dangers involved in use of the product, and, where called for, directions for its use. There is no dispute that the seller is under a duty to give adequate warning of unreasonable dangers involved in the use of which he knows, or should know." W. Prosser, Torts § 96 at 646-647 (4th ed. 1971), and cases cited. In this case, the manual accompanying the plaintiff's automobile contained no warnings of these driving hazards, and affirmatively represented the differential as a safety device.
The inapplicability of such a presumption, however, does not require a plaintiff to present direct proof of the manufacturer's knowledge. As we said in Haley v. Allied Chem. Corp., 353 Mass. 325, 330 (1967), quoting in part from Carney v. Bereault, 348 Mass. 502, 506 (1965), "The duty to exercise reasonable care includes a duty to warn of danger, if `the person on whom that duty rests has some reason to suppose a warning is needed.'" See Restatement (Second) of Torts § 388 (1965). Evidence that the differential was designed by the defendant's engineers who knew of its intended use, the conditions under which it would be operated, and that its very utility included attendant risks permits an inference that the defendant in the exercise of reasonable care should have foreseen and given warning of these probable dangers. See Annot., 76 A.L.R.2d 9 (1961), and Later Case Service 312 (1975).
The judge's instructions to the jury were appropriate on the limited scope of the evidence at the trial, but the *175 verdict of the jury may have been the result of the action of the judge in unduly restricting certain evidence which we discuss below.
3. The judge admitted language from owners' manuals issued by the defendant in 1968, 1969, and 1970,[1] as evidence of the operational characteristics of the differential, the parties having agreed that the design of the differential had not changed from that used in the plaintiff's 1963 automobile. The jury were instructed that they could consider the language of those manuals on the questions whether a risk existed in 1963 and whether the defendant knew or should have known of such risk. The plaintiff contended both at the trial and before this court that the statements contained in the defendant's manuals for those three years should have been considered for other purposes as well. We agree with that contention. The judge correctly instructed the jury that the manuals cannot ordinarily be considered as admissions of prior negligence or fault. But this rule of evidence has given rise to numerous exceptions.[2] The evidence was also admissible to prove *176 the practical possibility of giving cautionary warnings. doCanto v. Ametek, Inc., supra. Coy v. Boston Elev. Ry., 212 Mass. 307, 309-310 (1912). Beverley v. Boston Elev. Ry., 194 Mass. 450, 458 (1907). Such evidence would bear "directly on the question whether ... the defendant had done all that was practicable to prevent such an accident as occurred." Coy v. Boston Elev. Ry., supra.[3] The 1968 1969, and 1970 manuals were relevant in determining the defendant's duty to warn the plaintiff of the danger of the differential which was included in the 1963 Cadillac. doCanto v. Ametek, Inc., supra at 781-782.
The judge admitted the 1968-1970 manuals only as evidence of the operating characteristics of the differential and of the defendant's knowledge of the associated risks. Thus counsel for the plaintiff was required to delete certain cautionary warnings when referring to the manuals in the jury's presence and, for example, he was not permitted to refer to the word "CAUTION" or the phrase "care should be taken to avoid" which appeared in the 1969 manual.[4] The manuals themselves were not permitted to go to the jury. Because we have ruled that the manuals were admissible to show the feasibility of giving warnings, we hold that this deletion of cautionary language was error.[5]
Because these evidentiary errors entitle the plaintiff to a new trial on the count for failure to give warning, we *177 consider the further question raised by the parties which may arise at any retrial.
Our concern is not with the precision of electronic calculations, but with the accuracy and completeness of the *178 initial data and equations which are used as ingredients of the computer program. More generally, we feel that the standard for admissibility of scientific tests may not have been met in this instance. That standard was clearly enunciated in Commonwealth v. Fatalo, 346 Mass. 266, 269 (1963): "Judicial acceptance of a scientific theory or instrument can occur only when it follows a general acceptance by the community of scientists involved." Cf. Commonwealth v. A Juvenile, 365 Mass. 421, 425 (1974). The authorities cited by the parties show substantial disagreement on the reliability of computer simulation. We recognize that this process has become increasingly refined under the demands of modern technology and the situation may have changed with developments since the original trial of this action. Whether the simulation technique has achieved sufficient reliability and acceptance to warrant its use in judicial proceedings is a question to be decided in the first instance by the trial judge.
5. The plaintiff argues that the "charge was fatally defective in that it did not require that plaintiff's contributory negligence be a `substantial factor' in causing his injuries or a `proximate cause' thereof." We find no error in the charge on contributory negligence, taken as a whole. However, in so far as it may be relevant to litigation not affected by our comparative negligence statute, G.L.c. 231, § 85,[6] we note our adherence to the principle *179 of Restatement (Second) of Torts § 465 (2) (1965): "The rules which determine the causal relation between the plaintiff's negligent conduct and the harm resulting to him are the same as those determining the causal relation between the defendant's negligent conduct and resulting harm to others."
[1] The text describing the differential was substantially the same in the three manuals. The 1969 manual, for example, stated: "CONTROLLED DIFFERENTIAL The optional Controlled Differential (available on all models except the Eldorado) provides additional traction on snow, ice, mud, sand and gravel, particularly when one drive wheel is on a surface providing poor traction.
[2] We do not deem it presently necessary or advisable to consider whether these numerous exceptions have in effect overwhelmed the basic rule, or to adopt the plaintiff's suggestion that the amendment of the manuals is sufficiently different from a subsequent repair to warrant creating a separate rule of evidence.
[3] We have previously noted that a defendant's general concession of the feasibility of safety precautions will not render this evidence inadmissible. See doCanto v. Ametek, Inc., supra at 781, rejecting any suggestion to the contrary in Conry v. Boston & Me. R.R., 227 Mass. 411, 414-415 (1917).
[5] We do not accept the plaintiff's contention that the "Doctrine of Verbal Completeness" necessarily prevents the deletion of language not otherwise admissible. Public policy may require that prejudicial words be struck (cf. Commonwealth v. Lannon, 364 Mass. 480, 482-484 [1974]), particularly where the omissions are not "essential to a complete understanding of what... [the speaker] intended to express by the particular phrases and language which he used." Commonwealth v. Keyes, 11 Gray 323, 324 (1858).
[6] The "cause of action" in this case arose before January 1, 1971; hence G.L.c. 231, § 85, as appearing in St. 1969, c. 761, which established the doctrine of comparative negligence, is not applicable.
