PATRICIA D. VENINI & another vs. JOHN J. DIAS & another.

GOODMAN, J. This action for negligence brought by Patricia D. Venini and her husband, Roy G. Venini, arises out of an accident which occurred on the Massachusetts Turnpike after dark on April 6, 1970. Mrs. Venini claims damages from the defendant Dias for personal injuries she suffered when the automobile which she was driving struck a rear wheel and axle assembly lying on the road. The assembly had become detached from the automobile owned and driven by the defendant Dias. Roy G. Venini claims consequential damages. The plaintiffs also claim damages from Cohasset Motors, Inc. (Cohasset), alleging that the motor vehicle operated by Dias "was purchased from COHASSET . . . [and] was defective in its make, manufacture, design, preparation and maintenance . . . ." The defendant Dias, on November 1, 1971, filed a third-party declaration (G. L. c. 231, Section 4B, as amended through St. 1968, c. 324; see now Mass.R.Civ.P. 14[a], 365 Mass. 760 -761 [1974]) impleading Cohasset and the Ford Motor Company and alleging that he had purchased the vehicle from the third-party defendants and that it was defective. The plaintiffs appeal from judgments for the defendants Dias and Cohasset; they contend that it was error to direct verdicts for those defendants, and they also attack various evidentiary rulings, including the judge's refusal to permit one Mudie, a service manager for a Ford dealership, to testify as an expert. (1) We hold that this ruling was erroneous and reverse the judgment entered in favor of Dias; (2) we affirm the judgment entered in favor of Cohasset.

1. The plaintiffs called Mudie as a witness after the plaintiff, Roy G. Venini, who was a mechanic and had inspected the detached wheel and axle assembly, described in detail its condition, including a broken bearing. After a voir dire on Mudie's qualifications, the judge ruled that he

would "not accept his testimony in this case as an expert."

We have in mind that "[i]n determining the qualifications of an offered expert the trial judge has a wide discretion which is seldom disturbed." Muzi v. Commonwealth 335 Mass. 101, 106 (1956). And the Supreme Judicial Court has "often stated that `[w]hether a witness who is called as an expert has the requisite qualifications and knowledge to enable him to testify, is a preliminary question for the court. The decision of this question is conclusive, unless it appears upon the evidence to have been erroneous, or to have been founded upon some error in law.' Perkins v. Stickney, 132 Mass. 217, 218 [1882], and cases cited." Louise Caroline Nursing Home, Inc. v. Dix Constr. Corp., 362 Mass. 306, 309 (1972). But as with preliminary questions of fact generally, "the judge must act within the scope of a sound judicial discretion. His decision will be reversed where plainly erroneous . . ." -- where the decision is "plainly incorrect." Southwick v. Massachusetts Turnpike Authy., 339 Mass. 666, 668-669 (1959), citing Muskeget Island Club v. Nantucket, 185 Mass. 303, 304-306 (1904). Old Silver Beach Corp. v. Falmouth, 266 Mass. 224, 226 (1929). [Note 1] See Coghlan v. White, 236 Mass. 165, 167-168 (1920); Kelley v. Jordan Marsh Co., 278 Mass. 101, 106-108 (1932). Cases of reversal of a trial judge's determination of an expert's qualifications are rare, but see Muskeget Island Club v. Nantucket, supra; Old Silver Beach Corp. v. Falmouth, supra at 225-227; Muzi v. Commonwealth, supra; Newton Girl Scout Council, Inc. v. Massachusetts Turnpike Authy., 335 Mass. 189, 197-198 (1956); Ford v. Worcester, 335 Mass. 723, 723-724 (1957). Compare Commonwealth

v. Banuchi, 335 Mass. 649, 655-656 (1957) (exclusion of expert testimony held to be error where the trial judge misunderstood the relevance and purpose for which it was offered). But we are of the opinion that in this case the judge's determination cannot stand.

The judge ruled: "So on the evidence I have here, I am satisfied that this man is, indeed, a certified [service ?] manager of the Ford dealership over a period of years and whatever his experience is, whatever his knowledge is incidental to that world. As far as his qualifying as an expert to give his opinion about anything other than the ordinary mechanics of the running of the service department, as he has described it to me, I have concluded that he is not an expert" (emphasis added). Counsel for the plaintiffs observed that "[h]e hasn't given any testimony, yet," and the judge then indicated that he would not permit counsel to "proceed in any direction."

This was too sweeping a prohibition. Such total foreclosure is inconsistent with Mudie's experience as accepted by the trial judge. Thus in describing "the ordinary mechanics of the running of the service department" Mudie testified that a good part of his work was "diagnostic" which he defined as "evaluating a problem that a customer might have on the automobile, evaluating that problem, more or less as quickly as possible, while he is there. Explain to him what it would need." As part of this "diagnostic" work he would road test vehicles when people came in with complaints. He was asked, "People come to you and complain of noises in various parts of the car and you take a road test; is that correct?" He answered, "Constantly." He also replied in the affirmative to the question, "And you evaluate where the problem is and what the problem is and assign it?"

There may well be certain areas concerning the cause of the break in the bearing with reference to which Mudie might reasonably have been held to be unqualified as an expert, but that did not warrant complete exclusion of his testimony. See Southwick v. Massachusetts Turnpike Authy., 339 Mass. at 671. One can obviously qualify as an expert

concerning some matters but not concerning other related matters. Leach & Liacos, Massachusetts Evidence 97-98 (4th ed. 1967). See Commonwealth v. Seit, 373 Mass. 83, 91-92 (1977). Mudie was not being called upon to give his opinion as to what caused the bearing to break. The plaintiffs specifically disavowed this purpose, and the emphasis of their offer of proof was on the manifestations which would precede the detachment of the defective wheel and axle. The plaintiffs offered to show, among other things, that, given the broken bearing, a noise becoming progressively louder would have been produced well before the assembly became detached and would have warned Dias that something was amiss. Mudie's empirical expertise [Note 2] clearly qualified him to testify at least to the probability of such a manifestation -- regardless of his lack of formal training in metallurgy or the like. Cunningham v. Gans, 507 F. 2d 496, 500 (2d Cir. 1974). Moran v. Ford Motor Co., 476 F. 2d 289, 291 (8th Cir. 1973). See Olsen v. New England Fuel Transp. Co., 251 Mass. 389, 392 (1925); Varney v. Donovan, 356 Mass. 739 (1970); Wilborg v. Denzell, 359 Mass. 279, 283 (1971).

We need not consider Dias' motion for a directed verdict, since he does not contend that he would have been entitled thereto if Mudie had been permitted to testify. Nor need we deal with other rulings on evidence which the plaintiffs have argued, since they may arise (if at all) in a different context.

2. The plaintiffs' brief does not appear to press their appeal from the judgment in favor of Cohasset. No argument is made concerning the directed verdict in favor of Cohasset;

Page 700

nor do the plaintiffs make any argument relative to Cohasset on the evidentiary rulings.

Accordingly, the judgment entered in this case is reversed; a judgment is to be entered for Cohasset on counts five, six, and nine of the plaintiffs' complaint. The case is to stand for trial on counts one, two and seven of the complaint against Dias and on the third-party complaint by Dias.

So ordered.
