No. 11755. The Hecht Company appeals from a judgment in favor of appellee Julia McLaughlin, plaintiff below, a customer of its department store. She was awarded damages for injuries suffered in circumstances attributed by the jury to the negligence of the Company.

There was evidence the plaintiff in seeking to leave the store came from the Men's Department into a lobby or vestibule from which three doors lead to the street. These doors are used interchangeably for exit and entrance, without designation for either one or the other use. Each door is so constructed and installed that when pulled open from the outside about one-third of its total width projects inward. Thus, unlike an ordinary door, it does not swing entirely in one direction. There was no evidence of guard rails or bars extending out from the wall where the doors were located to aid in protecting against the inward projection.

There was evidence that this 'balanced' type of door, due to less air pressure, facilitates ease of manipulation and accommodates a more rapid flow of people. There was considerable evidence as to the use of these doors in a large number of establishments, and their approval by public authorities in the District of Columbia and the states. There was also evidence that plans for The Hecht Company building, including this type of door and prepared by architects, were examined and approved by public authorities of the District of Columbia before the building permit was issued, and that the doors had been in use for some years without mishap.

Plaintiff testified that as she came toward the doors to leave the store she saw a lady approaching from the outside. Plaintiff sought to walk beyond the door nearest to herself, which she observed was about to be used by the approaching lady, and make her exit through the next one. Before she could do so she was struck by the inward-projecting edge of the door pulled open by the incoming lady.

The Company first contends that the trial court erred in denying its motion [93 U.S.App.D.C. 384] for a directed verdict at the close of all the evidence.

We agree with the court below that the evidence above outlined raised an issue of fact for the jury as to whether the Company had exercised reasonable care to prevent injury to its customers. The question was not one of law for the court. On this aspect of the case the factual issue was fairly submitted to the jury in the court's charge, set forth in the margin.1

We think, however, that error occurred in the handling of problems growing out of a building regulation admitted in evidence. The regulation is headed 'Aisles and Corridors' and reads in part, 'Doors shall not swing into passageways'.2 The court, apparently holding that the regulation applied to the situation presented, instructed the jury that its violation by the Company would be negligence as matter of law. Elsewhere, as we have seen, the court submitted to the jury on the whole evidence the ultimate question of negligence; but if this particular instruction was erroneous, or if evidence material on the question of admissibility of the regulation was excluded, a new trial should be authorized.

Discussing first the question of application and, therefore, of admissibility of the regulation, the Company offered, and the court rejected, testimony of a liaison officer of the District of Columbia Building Department that Article 601-09, entitled 'Aisles and Corridors', n. 2, supra, did not apply to the situation before the court. We think this evidence should have been heard. As we have seen, the installation of the door at this place had been approved by the Department of Building Inspection, both before a permit was issued and upon inspection after installation. There was evidence that installations of a similar character had been made in the District of Columbia at Georgetown University Hospital, Woodward & Lothrop's Department Store, Lansburgh's Department Store, the Statler Hotel, and elsewhere. As noted above, the door is not the ordinary type which swings in the usual sense. Uncertainty accordingly arises as to whether for this or any other reason the 'Aisles and Corridors' Article applies. In these circumstances the expert or administrative view would be material and helpful. In Wright v. Wardman, 55 App.D.C. 318, 5 F.2d 380, it is held that where the language of an [93 U.S.App.D.C. 385] ordinance or regulation is doubtful and open to different interpretations the construction placed upon it by the department charged with its execution will generally control. The court approved this rule in a case turning upon the meaning of zoning regulations having to do with the type of erection which required the consent of adjoining property owners before issuance of a permit. The court said the construction adopted by the authorities should be adhered to. See, also, Coombe v. United States, 55 App.D.C. 190, 3 F.2d 714. An analogy is also found in the reception of expert testimony to aid the court in the interpretation of a city ordinance when some of its language appeared to have a special meaning. City of Chicago v. Holden, 194 Ill. 213, 62 N.E. 550. A further analogy is the use of such testimony in aid of interpreting technical words or phrases in documents. See Seymour v. Osborne, 11 Wall. 516, 546, 78 U.S. 516, 546, 20 L. Ed. 33; Phillips Petroleum Co. v. Payne Oil Corporation, 10 Cir., 146 F.2d 546; 7 Wigmore, Evidence Sec. 1955 (3d ed.). And while the court should interpret an ordinance without the aid of expert testimony when there is no ambiguity, Montgomery Ward & Co. v. Snuggins, 8 Cir., 103 F.2d 458, 460-462, here ambiguity appears.

The alternative to holding that the trial court should have received the expert testimony is for us to rule on the present record whether or not the regulation applied and was admissible.3 This would be unwise without the benefit of available relevant evidence, followed by a ruling by the trial judge after hearing it.

Good practice would indicate that the evidence should be heard out of the presence of the jury, its quantity being held within reasonable limits in the exercise of a sound discretion. The expert or administrative interpretation which might be shown by such evidence is not binding on the court. It is to be received to aid the court in resolving the ambiguity or uncertainty above referred to, and thus in determining whether or not the regulation applies and is admissible.4

There remains the question whether violation of such a regulation, assuming it has been properly admitted in evidence, constitutes negligence per se. This court said in Ross v. Hartman, 78 U.S.App.D.C. 217, 139 F.2d 14, 158 A.L.R. 1370, certiorari denied, 321 U.S. 790, 64 S. Ct. 790, 88 L. Ed. 1080, that violation of a safety measure constitutes negligence. That case, however, involved a simple act contrary to the terms of a clear regulation that no person should allow a motor vehicle he operated to stand unattended on any street without having locked the switch. A truck had been left on the street unattended, with the ignition unlocked and the key in the switch. Accordingly, this court applied the general rule that breach of an ordinance intended to promote safety is negligence. This general rule, however, was held inapplicable in the subsequent case of Peigh v. Baltimore & O.R. Co., 92 U.S.App.D.C. 198, 204 F.2d 391. We there characterized the doctrine of negligence per se as one to be applied cautiously, with an eye to essential fairness. While it is clear the regulation involved in the present case is a safety measure, there is unequivocal evidence the Company obtained the approval of public and architectural authorities before installing this door at this place. This is indicative of care on the Company's part, quite inconsistent with the theory that violation of the regulation alone, all else aside, is negligence as matter[93 U.S.App.D.C. 386] of law. To apply this doctrine to the facts of this case would be essentially unfair.5 The question of the Company's negligence is to be decided on all relevant evidence, including violation of any safety regulation found to be applicable, and consequently admissible in evidence, but including also facts tending to show due care on the part of the Company in the selection and installation of the door. Had the instruction which the court gave in general terms, see n. 1, supra, been all, we would have no difficulty. But the additional and particular instruction regarding violation of the regulation, which we hold was erroneous, might have been the one relied upon by the jury in finding negligence.

We have considered and find no error as to other questions raised; but the failure to receive expert testimony as to the interpretation, and consequent admissibility and application, of the regulation, and the instruction that its violation would constitute negligence per se, require reversal.

No. 11756. In No. 11756 The Hecht Company appeals from dismissal, based upon the statute of limitation, of its third-party complaint against the Ellison Bronze Company, Inc., third-party defendant. The complaint of The Hecht Company against the Bronze Company alleges that the latter manufactured, constructed and installed the doors in 1945 and that at the time of the accident they were in the same condition as when installed. The complaint prays that in the event Julia McLaughlin should recover against The Hecht Company it in turn recover from the Bronze Company. This third-party complaint was filed in March, 1951. The installation of the doors in fact occurred about ten years earlier, in 1941.

In this court The Hecht Company states that the basis of the third-party action is both breach of warranty and negligence. It is not suggested that there was any express warranty. And there is no breach of an implied warranty because The Hecht Company obtained from the Bronze Company in all respects exactly what it sought. As to negligence, we do not think the facts made out a case for indemnification of The Hecht Company by the Bronze Company, assuming recovery by McLaughlin against the former; for a jury would not be warranted in finding that, after the doors had been in place at this location for so long a time, with their use and maintenance, and their surroundings, controlled only by The Hecht Company, the injury to McLaughlin could in any proximate sense be attributed to the Bronze Company. Finally, no theory of express contract for indemnification is advanced, or present. So that whether or not any applicable statute of limitation had run,6 we will not disturb the dismissal of the third-party complaint.

No. 11755 is reversed and remanded.

No. 11756 is affirmed.

WILBUR K. mIller, Circuit Judge (dissenting).

I do not agree with the statement in the court's opinion that the evidence raised an issue for the jury as to whether The Hecht Company had exercised reasonable care to prevent injury to its customers. Transparent doors of this modern type, even though installed three in a row, do not seem to me to be potentially dangerous so as to require any sort of warning, guard or protection; therefore I do not think the jury should have been permitted to decide the company was negligent in so installing them. My view if that the plaintiff's injury was [93 U.S.App.D.C. 387] caused either by her own negligence or by the concurrence of her negligence with that of the other customer who opened the door from the outside and caused it to strike the plaintiff. I would reverse and direct the entry of a judgment in favor of The Hecht Company.

But, if it be assumed that the evidence did raise an issue for the jury, I think the court's disposition of the matter is correct.
