LEO COYNE vs. JOHN S. TILLEY CO., INC. (and a companion case [Note 1]).

TAURO, C.J. These are two actions of tort in which the plaintiff seeks to recover for injuries suffered in a fall from an aluminum stepladder. In his declarations, [Note 2] the plaintiff alleges that his fall "was due to the negligent and careless manner in which said ladder was manufactured, designed, and constructed." The two actions were consolidated for trial in the Municipal Court of the City of Boston. In the action brought against the manufacturer of the ladder, John S. Tilley Co., Inc. (Tilley), the trial judge, after denying the defendant's request for

Page 232

rulings, [Note 3] found for the plaintiff in the amount of $1,000. In the action brought against the wholesaler of the ladder, Lynn Ladder Co., Inc. (Lynn Ladder), the trial judge, after denying five [Note 4] of the plaintiff's six requests for rulings, found for the defendant. The plaintiff and Tilley, alleging that they were aggrieved by the judge's denial of their requests for rulings, claimed reports to the Appellate Division of the Municipal Court of the City of Boston. G. L. c. 231, Section 108. These reports were consolidated into a single report which stated that it "contains all the evidence material to the questions reported." The Appellate Division vacated the judge's finding for the plaintiff against Tilley and directed that a finding be entered for the defendant in each case. We treat the Appellate Division's order that a finding be entered for Lynn Ladder as a dismissal of the report in the plaintiff's case against Lynn Ladder. The plaintiff appealed to this court from the Appellate Division's orders. We transferred the cases to the Appeals Court.

Page 233

G. L. c. 211A, Section 12. The Appeals Court affirmed the orders of the Appellate Division in both cases. Coyne v. John S. Tilley Co. Inc. 2 Mass. App. Ct. 641 (1974). The cases are before us for further appellate review on the plaintiff's application. The principal question presented for our decision is whether the evidence warranted a finding for the plaintiff in either case.

We summarize the evidence contained in the report to the Appellate Division of the Municipal Court of the City of Boston in its aspect most favorable to the plaintiff. The plaintiff was employed as a night cleaner by York Realty, Inc. (York). On the evening of May 12, 1969, the plaintiff ascended a six-foot aluminum stepladder in order to wash an overhead transom and door. After he had perched on the ladder "for a minute or so," a leg of the ladder "collapsed inward at a 45 degree angle." The plaintiff was thrown to the floor and suffered injuries. Prior to the accident, the ladder had appeared to the plaintiff to be "free of defects." "[T]he legs were straight, the finish was clean and bright, and it appeared new."

The ladder in question was manufactured by the defendant Tilley. At some unstated time, the ladder was sold by Tilley to Lynn Ladder, also a defendant. On March 26, 1969, Lynn Ladder sold the ladder to Warren Electric & Hardware Supply Co., Inc. (Warren), which sold the ladder to York the following day. There was evidence that, before Lynn Ladder shipped ladders to customers, the ladders were inspected. There was further evidence that the president of Lynn Ladder examined the ladder in question prior to shipment to Warren and found it in good condition without apparent defects.

The ladder was stored by York in the cellar storeroom of the building in which the plaintiff was working on the night of his accident. At some unspecified time, the night supervisor of the building, the plaintiff's brother, had removed the ladder from the storeroom and had given it to the plaintiff for use in his job. There was

Page 234

evidence that the night supervisor had observed the ladder and thought it free from defects: "[T]he legs were straight, and the surface of the ladder was shiny and free from dirt or paint."

The plaintiff's theory of recovery in each case is the principle of negligence we announced in Carter v. Yardley & Co. Ltd. 319 Mass. 92, 96 (1946): "[A] manufacturer or other person owning or controlling a thing that is dangerous in its nature or is in a dangerous condition, either to his knowledge or as a result of his want of reasonable care in manufacture or inspection, who deals with or disposes of that thing in a way that he foresees or in the exercise of reasonable care ought to foresee will probably carry that thing into contact with some person, known or unknown, who will probably be ignorant of the danger, owes a legal duty to every such person to use reasonable care to prevent injury to him." Accord, Ricciutti v. Sylvania Elec. Prod. Inc. 343 Mass. 347, 352-353 (1961). The plaintiff argues that the defendants had a duty to discover defects in the ladder which, in his view of the evidence, caused its collapse when it was put to a normal and foreseeable use.

Though the Yardley case eliminated the privity of contract requirement in actions for the negligent manufacture and sale of a product (Carter v. Yardley & Co. Ltd., supra, at 96-97, 104), the case did not relieve the plaintiff of the burden of proving that a defect attributable to a manufacturer's (and in this case a wholesaler's as well) negligence caused his injuries. LeBlanc v. Ford Motor Co. 346 Mass. 225, 230 (1963). Carney v. Bereault, 348 Mass. 502, 506 (1965). In the instant case, the plaintiff has adduced no direct evidence as to the specific acts or omissions by the defendants which constituted negligence and as to the specific defect of manufacture which caused the accident. Cf. Kalash v. Los Angeles Ladder Co. 1 Cal. 2d 229 (1934). To sustain his burden of proof, the plaintiff relies on circumstantial evidence and, consequently, on an inference

Page 235

of negligence which, he claims, one may permissibly draw from the occurrence of the accident. We pass to a consideration of the sufficiency of the evidence to support that inference against each defendant.

THE CASE AGAINST TILLEY.

The nature of the inference on which the plaintiff would rely in this case has been described in Evangelio v. Metropolitan Bottling Co. Inc. 339 Mass. 177, 180 (1959): "[T]he tribunal of fact [is permitted], if it sees fit, to draw from the occurrence itself of an unusual event the conclusion that it would not have happened unless the defendant had been negligent. It does no more than recognize that negligence and causation, like other facts, may be established by circumstantial evidence." Accord, Roscigno v. Colonial Beacon Oil Co. 294 Mass. 234 (1936). In drawing this inference and determining that there is a balance of probabilities in favor of negligence, the trier of fact must be able to find, either from common knowledge (Graham v. Badger, 164 Mass. 42, 47 [1895]; Zentz v. Coca Cola Bottling Co. of Fresno, 39 Cal. 2d 436, 442 [1952]) or from expert testimony (James v. Boston Elev. Ry. 204 Mass. 158, 162 [1910]; LeBlanc v. Ford Motor Co. 346 Mass. 225, 231 [1963]) that the occurrence of the accident shows negligence as a cause. Roscigno v. Colonial Beacon Oil Co., supra, at 235. Evangelio v. Metropolitan Bottling Co. Inc., supra, at 182.

We believe that a trier of fact could infer as matter of common knowledge [Note 5] that a relatively new aluminum stepladder would not collapse in such a way that one of its legs was bent inward in a 45 degree angle in the course of usage unless someone had been negligent. Plainly, a properly fabricated and designed aluminum ladder

Page 236

which had received proper care and usage would not collapse if put to the use for which it was intended. See Jiminez v. Sears, Roebuck & Co. 4 Cal. 3d 379, 387 (1971). There are numerous conceivable acts of negligence which might have contributed to the collapse: A leg of the ladder might have been constructed with defective materials and then inadequately tested by the manufacturer. The ladder might not have been designed to support a load which the manufacturer should reasonably have expected the ladder to hold. The ladder might have been mishandled by a middleman in the distribution process. At the time of the accident, a leg of the ladder might have been positioned in such a way that it could not withstand the weight applied, or, in the alternative, the weight applied might have been excessive when considered in light of the ladder's manifest construction and design. In any event, the likelihood that the collapse was caused by some negligent act could be found to be greater than that it was not. Just as in the case of a mysteriously exploding bottle (see Evangelio v. Metropolitan Bottling Co. Inc., supra) or a mysteriously malfunctioning automobile transmission (see LeBlanc v. Ford Motor Co. 346 Mass. 225 [1963]), the occurrence of this accident will support an inference of negligence. [Note 6]

However, the above mentioned inference alone will not support a finding for the plaintiff in the instant case.

Page 237

"Where, as here, the accident occurs after the defendant has surrendered control of the instrumentality involved, it is incumbent upon the plaintiff to show that the instrumentality had not been improperly handled by himself or by intermediate handlers." Evangelio v. Metropolitan Bottling Co. Inc. 339 Mass. 177, 183 (1959). Rafferty v. Hull Brewing Co. 350 Mass. 359, 363 (1966). The evidence introduced must be of such a nature that it warrants a reasonable inference that the particular defendant-manufacturer, rather than another, bears responsibility for the negligence which, one may infer, caused the accident. Zentz v. Coca Cola Bottling Co. of Fresno, 39 Cal. 2d 436, 447 (1952). Harper & James, Torts, Section 19.7, pp. 1085, 1093-1094 (1956). See Rafferty v. Hull Brewing Co. 350 Mass. 359, 362 (1966).

We believe that the plaintiff's evidence was sufficient to warrant exclusion of negligence by intermediate handlers as a cause of the ladder's collapse. Cf. Kenney v. Sears, Roebuck & Co. 355 Mass. 604, 607 (1969). There was evidence that three people, the president of Lynn Ladder, the night supervisor, and the plaintiff, had observed the ladder and had noticed no defects. There was evidence that, prior to the accident, the ladder had appeared new to the plaintiff. Its finish had been clean and bright. The trier of fact could deem it improbable that a ladder which appeared bright, new and defect-free to these observers had been damaged significantly by handling between the time it left the manufacturer's control and the time of the plaintiff's use. [Note 7] See Hewitt v. General Tire & Rubber Co. 3 Utah 2d 354, 360 (1955). Cf. Andrews v. Barker Bros. Corp. 267 Cal. App. 2d 530 (1968). In this respect, this case is similar to prior cases in which evidence of the intact appearance

Page 238

of a carton used in transporting bottles (Jankelle v. Bishop Indus. Inc. 354 Mass. 491, 493 [1968]) and of the defect-free appearance of a carbonated beverage bottle at the time of sale (MacDonald v. Najjar, [Note 8] 362 Mass. 119, 122 [1972]) was held sufficient to warrant a finding that the bottles had not been damaged by handlers intervening between the injured victim and a defendant manufacturer. Cases such as Selissen v. Empire Bottling Co. Inc. 343 Mass. 779 (1962), and Rafferty v. Hull Brewing Co. 350 Mass. 359 (1966), in which no admissible evidence of due care by intermediate handlers was introduced, are distinguishable.

Though the evidence presented by the plaintiff was sufficient to warrant a finding that the actions of intermediate handlers had not contributed to the ladder's collapse, his evidence was insufficient to exclude his own actions as a cause for the ladder's collapse. The evidence concerning the plaintiff's use of the ladder is meager. The report recites only the most general evidence about the plaintiff's actions prior to the accident. It notes only that he was on the ladder briefly while washing the door and overhead transom. There is no evidence that the plaintiff put the ladder to the normal use for which it was intended. Cf. Andrews v. Barker Bros. Corp. 267 Cal. App. 2d 530, 533 (1968). He could have overloaded the ladder with a variety of cleaning paraphernalia or could have placed the ladder so that the leg which subsequently was bent inward bore an inordinate proportion of the weight. From the evidence, a finder of

Page 239

fact could not say that it is more likely that the plaintiff handled the ladder properly than that the collapse of the ladder resulted from his contributory actions or carelessness. Cf. LeBlanc v. Ford Motor Co. 346 Mass. 225, 231 (1963) (testimony by the plaintiff and another that selector lever of car was in neutral position at time of accident). Without further evidence, [Note 9] "[i]t cannot be said, when a step ladder breaks, that the fact of its breaking by common experience points more closely to a defect in the appliance than to some carelessness on the part of the person using it." Drum v. New England Cotton Yarn Co. 180 Mass. 113, 114 (1901).

Accordingly, we hold that the evidence is insufficient to warrant the plaintiff's recovery against Tilley and that the trial judge erred in denying Tilley's request for a ruling that "[t]he evidence does not warrant a finding that the defendant, its agents, or servants was [sic] negligent." "[T]he inference of negligence does not point to the defendant until the plaintiff himself has been eliminated as a cause." Prosser, Res Ipsa Loquitur in California, 37 Cal. L. Rev. 183, 201 (1949). "The plaintiff need not exclude every possible cause for his injuries. He is only required to show a greater likelihood that his injury was caused by the defendant's negligence than by some other cause." Jankelle v. Bishop Indus. Inc. 354 Mass. 491, 494 (1968). MacDonald v. Najjar, 362 Mass. 119, 122 (1972). This he did not do. [Note 10]

Page 240

There is no merit to the plaintiff's contention that the requirement that he exclude his own actions as a cause of the ladder's collapse contravenes G. L. c. 231, Section 85 (as appearing in St. 1973, c. 1123, Section 1). The statute provides that "the plaintiff shall be presumed to have been in the exercise of due care" and places the burden of proving contributory negligence by the plaintiff on the defendant. It is settled that the statute did not "change the substantive law of negligence in any respect, but simply affected procedure and the burden of proof." Perry v. Boston Elev. Ry. 322 Mass. 206, 209 (1948). "[T]he whole practical effect of the statute" is to place the burden of proof of contributory negligence on the defendant. Id. at 210. Potter v. John Bean Div. of Food Mach. & Chem. Corp. 344 Mass. 420, 425-426 (1962). Yet, the requirement that the plaintiff eliminate his own handling of the product as a cause of his injuries is analytically distinct from a requirement, in violation of the statute, that he prove the absence of contributory negligence. Generally, we agree that the requirement, in cases such as this, that the plaintiff exclude his own actions as a cause of his injuries "should not be confused with the problem of contributory negligence, as to which defendant has the burden of proof, and its purpose, like that of control by the defendant, is merely to assist the court in determining whether it is more probable than not that the defendant was responsible for the accident." Zentz v. Coca Cola Bottling Co. of Fresno, 39 Cal. 2d 436, 444 (1952). Proof which excludes the plaintiff's

Page 241

handling of the product as a cause of its failure "complete[s] the basis for an inference," drawn from the occurrence of the accident, that the defendant-manufacturer's negligence proximately caused the plaintiff's injuries. Harper & James, Torts, Section 19.8, p. 1093 (1956). Frumer & Friedman, Products Liability, Section 12.03 [4], pp. 306-307 (1974). Without such proof, the fact finder could not conclude that the occurrence of the accident was most likely caused by the negligence of that particular defendant.

THE CASE AGAINST LYNN LADDER.

The plaintiff's case against Lynn Ladder must fail for the same reasons as his case against Tilley. The plaintiff has presented sufficient evidence so that an inference can be drawn that the collapse of the ladder resulted from some negligent act. He has not, however, sufficiently excluded his own actions as a cause of its collapse. His evidence is insufficient to demonstrate that some defect in the ladder more probably than not caused its collapse. Thus, a trier of fact could not find from the evidence introduced that a failure of Lynn Ladder to inspect the ladder so as to discover the defect, if, in fact, Lynn Ladder had such a duty of inspection [Note 11] (compare O'Brien v. Louis K. Liggett Co. 282 Mass. 438, 441-442 [1933], and Kirk v. Stineway Drug Store Co. 38 Ill. App. 2d 415, 426-429 [1963], with Gauld v. John Hancock Mut. Life Ins. Co. 329 Mass. 724, 728 [1953], Fahey v. Osol, 338 Mass. 429, 434 [1959], Hadley v. Hillcrest Dairy, Inc. 341 Mass. 624, 631 [1961], and Burgess v. Montgomery Ward & Co. Inc. 264 F. 2d 495, 498 [10th Cir. 1959]; see generally Restatement 2d: Torts, Sections 401, 402

Page 242

[1965], and comments; anno. 6 A. L. R. 3d 12 [1966]), or mishandling by Lynn Ladder (see Rafferty v. Hull Brewing Co. 350 Mass. 359, 362 [1966]) amounted to negligence for which the plaintiff could have recovery. The judge properly denied the plaintiff's request for a ruling that "[t]he evidence warrants a finding for the plaintiff."

In the case against Tilley, the order of the Appellate Division vacating the finding for the plaintiff and directing a finding for the defendant is affirmed. In the case against Lynn Ladder, the order of the Appellate Division, which we have treated as an order dismissing the report, is affirmed. A judgment for the defendant is to be entered in each case.

So ordered.
