This was an action to recover for personal injuries sustained by a brick mason through the tipping of a plank in a temporary scaffold provided as a working place for him. The evidence produced upon the trial, although somewhat contradictory, reasonably tended to establish these facts: The defendant, in whose service the plaintiff was, was erecting a brick cross-wall between two outer walls, already partially completed, which conveniently may be spoken of as the east wall and the west wall. Between these outer walls, and parallel with them, was a partition wall, which also connected with the cross-wall. The scaffold extended along the cross-wall, from the west wall to the partition wall, and consisted of five or six heavy planks, supported at one end by another scaffold along the west wall and near the other end by a four-legged carpenter’s trestle. The trestle was as close to the partition wall as it could be, but the inclination of its legs was such that its top, upon which the planks rested, was a foot away from that wall. At that end the planks projected beyond the trestle from 21 to 30 indies; the projection of those next the cross-wall being less than that of the others, as was stated by a witness named Croisette. In this way the planks extended halfway or entirely over the top of the partition wall, which was 18 inches wide and about 14 inches below the scaffold. It was usual, in the erection of such a scaffold, to make provision against the tipping of the planks, either by placing a foot lock under the projecting end or by nailing down the other end. Either method would have been practicable and efficient'in this instance, but neither was followed. T\ .• scaffold was erected under the direction of the defendant’s foreman before the plaintiff went upon it, and when he had been at work there a short time one of the planks tipped, and precipitated him into a pit 25 feet below, between the partition wall and the east wall. He had nothing to do with the erection of the scaffold, did not know of the failure to make provision against the tipping of the planks, and did not observe anything indicating that they were not secure. He went upon the scaffold at the foreman’s direction, and in doing so did not
The first question to be considered is whether the court erred in denying a request, preferred by the defendant, for a directed verdict in its favor. It is not seriously insisted, nor could it be, that the evidence did not justify a finding of actionable negligence on the part of the defendant, under the state statute; but it is earnestly contended that it was conclusively shown that the plaintiff assumed the risk and ivas guilty of contributory negligence because he did nothing to satisfy himself of the security of the scaffold, and because it would have taken but a moment to ascertain how the planks were supported at the east end and whether they were nailed at the other end. The contention • uniot be sustained. It is the duty of a master to exercise reasonable care to provide a reasonably safe working place for his
The matter next to be considered is the admission, over the defendant’s objection, of testimony by a practical brick mason and builder of many years’ experience to the effect that a scaffold constructed and supported like the one in question was not as safe as those usually provided in like situations, but was very dangerous, because the weight of a man upon the projecting end of one of the planks was sure to make it tip. The objection made was, not that the witness was not qualified to speak as an expert, but that his opinion was elicited upon a matter which it was the province of the jury to decide, and which they were capable of deciding without such testimony. It is true that in trials by jury it is their province to determine the ultimate facts, and that the general rule is that witnesses are permitted to testify to the primary facts within their knowledge, but not to their opinions. And it is also true that this has at times led to the statement that witnesses may not give their opinions upon the ultimate facts which the jury are to decide, because that would supplant their judgment and usurp their province. But such a statement is not to be taken literally. It but reflects the general rule, which is subject to important qual-
The most important qualification of the general rule before stated' is that which permits a witness possessed of special training, experience, or observation, in respect of the matter under investigation, to testify to his opinion when it will tend to aid the jury in reaching a correct conclusion; the true test being, not the total dependence of the jury upon such testimony, but their inability to judge for themselves as well as is the witness. A reference to adjudicated cases will show the extent of this qualification, its application in actual practice, and the discretion accorded to the trial judge in that regard. In Transportation Line v. Hope,
“Tlie witness was an expert, and was called and testified as such. Ilis knowledge and experience fairly entitled him to that position. It is permitted to ask questions of a witness of this class which cannot be put to ordinary witnesses. It is not ail objection, as is assumed, that he was asked a question involving the point to be decided by the jury. As an expert he could properly aid the jury by such evidence, although it would not be competent to be given by an ordinary witness. It is upon subjects on which the jury are not as well able to judge for themselves as is the witness that an expert as such is expected to testify. Evidence of this character is often given upon subjects requiring medical knowledge and science, but it is by no means limited to that class of cases. It is competent upon the question of the value of land (Clark v. Baird,9 N. Y. 183 ; Barss v. Copely,10 N. Y. 93 ); or as to the value of a particular breed of horses (Harris v. Panama Railroad Co., 30 N. Y. Super. Ct. 373); or upon the value of thg professional services of a lawyer (Jackson v. New York Central Railroad Co., 2 Thomp. & C. [N. Y.] 653); or on the question of negligence in moving a vessel (Moore v. Westervelt, 9 Bosw. [N. Y.] 558); or on the necessity of a jettison (Price v. Hartshorn, 44, N. Y. 94,*412 4 Am. Rep. 645 ). In Walsh v. Washington Marine Insurance Co.,32 N. Y. 427 , it was decided that the testimony of experienced navigators on questions involving nautical skill was admissible. The witness in that case was asked to what cause the loss of the vessel was attributable, which was the point to be decided by the jury. The court sustained the admission of the evidence, using this language: ‘We entertain no doubt that those who are accustomed to the responsibility of command, and whose lives are spent on the ocean, are qualified as experts to prove the practical effect of cross-seas and heavy swells, shifting winds, and sudden squalls.’ The books give a great variety of cases in which evidence of this character is admissible, and we have no doubt of the competency of the evidence to which this objection is made.”
Spring Company v. Edgar,
“Whether a witness is shown to be qualified, or not, as an expert, is a preliminary question, to be determined in the first place by the court; and the rule is that, if the court admits the testimony, then it is for the jury to decide whether any, and, if any, what, weight is to be given to the testimony. Cases arise where it is very much a matter of discretion with the court whether to receive or exclude the evidence; but the appellate court will not reverse in such a case, unless the ruling is manifestly erroneous. * * * Even if the witnesses are not properly to be regarded as experts, the court is of the opinion that the testimony was properly admitted as a matter of common knowledge.”
In Connecticut Mutual Life Ins. Co. v. Lathrop,
In Union Ins. Co. v. Smith,
In Northern Pacific Railroad v. Urlin,
And in Gila Valley R. R. Co. v. Lyon,
“lu the cases of all the witnesses, we think the question of the admissibility of their evidence was one within the reasonable discretion of the trial court, and that the discretion was not abused. All the witnesses had had practical experience on railroads, and were familiar with structures and the character of buffers mentioned in the evidence. There was certainly enough to call upon the court to decide upon the admissibility of their opinions under these circumstances, and we ought not to interfere with the decision of the trial court in this case.”
In St. Louis, etc., Co. v. Edwards,
“The general rule undoubtedly is that witnesses are to testify to facts, and not to give thoir opinions; but this rule has its exceptions, as familiar and well settled as the rule itself. The exceptions rest upon the common ground of necessity. Among these exceptions is Ibis one: That a witness, having special knowledge and experience as to the value of property, animate or inanimate, and as to how the value of such property is affected by certain eondiiions or treatment, may give his opinion as to how much the properly was damaged or benefited by such conditions or treatment. In many cases ■witnesses are allowed to testify to their opinions, not because they are experts in the technical sense of tha t term, but because they have special knowledge of the particular facts in the case, which the jurors have not.”
In Western Coal & Mining Co. v. Berberich,
“But there is nothing which tends to belittle the authority of. the courts or to impair the confidence of Hie public in the certainty of justice as.much as the habit of reversing cases for slight errors in admitting testimony, or trifling slips in the charge. * * * Better by far the practice of the English courts and the federal Supreme Court, where every intendment is made in favor of the action of the lower court, and eases are rarely reversed except*414 for errors going to ttto very merits — errors which usually obviate the necessity of a second trial.”
In Chicago Great Western Ry. Co. v. Price,
“The trial court was of the opinion that the testimony of this witness fell under the exception to the rule, and we are not convinced that there was any error in this view. The line of demarcation between competent and incompetent expert testimony is not always clear and definite, and judgments ought not to be reversed on account of the reception or rejection of such testimony, unless there was a clear violation of the rule.”
And Southern Pacific Co. v. Arnett,
The same rational view of the use of expert and opinion testimony is also maintained in many of the state courts, -as the following cases will show: Porter v. Pequonnoc Mfg. Co.,
“The true test of the admissibility of such testimony is not whether the subject-matter is common or uncommon, or whether many persons or few have some knowledge of the matter; but it is whether the witnesses offered as experts have any peculiar knowledge or experience, not common to the world, which renders their opinions founded on such knowledge or experience any aid to the court or the jury in determining the questions at issue.”
Applying the true test to the testimony now under consideration, we think it cannot well be said that it was plainly inadmissible. Doubtless the farmers, stockgrowers, merchants, and clerks who composed the jury were more or less capable of judging of the safety of the scaffold in question and of the necessity for securing the planks in one of the modes suggested; but it is quite reasonable to believe that they were not as capable of doing so as a practical brick mason and builder of many years’ experience in the use and construction of scaffolds, and that the opinion of a witness possessed of the special knowledge which is born of such experience was calculated appreciably to aid them in reaching a correct conclusion. At all events, the trial judge was of opinion that the testimony was calculated to aid them, and therefore admitted it in evidence, and we are not persuaded that he exceeded the limits of his discretion.
Lastly, it is to be considered whether there was error in the following instruction on the measure of damages:
“If the plaintiff is entitled to any verdict at your hands, he is entitled to compensation. That compensation should be compensation for his pain and physical suffering and his mental suffering due to the injury, and also for the permanent impairment of his earning capacity, if any such impairment is shown by Ihe evidence. Tn considering the impairment to his earning capacity, you will make up your mind whether it is simply temporary or permanent. He is entitled io compensation for that impairment in ihe past, and also for such future impairment as you are satisfied by the evidence he will suffer.”
The defendant excepted to the words “and his mental suffering due to the injury,” but did not ask that they be explained in any way. It is now urged that the instruction permitted the jury to consider mental suffering even though it was separable from and independent of the physical injury, which would be contrary to the settled rule in this jurisdiction. Chicago, etc., Co. v. Caulfield,
An attentive consideration of the record and of the arguments of counsel discloses no reversible error, and so the judgment is affirmed.
