Neil L. CADE, Appellant,
v.
GREAT AMERICAN INSURANCE COMPANY, Appellee.
No. 2146.
Municipal Court of Appeals for the District of Columbia.
Submitted March 10, 1958.
Decided June 3, 1958.
*152 Donald A. Brown, Washington, D. C., for appellant.
G. Joseph Cooley, Washington, D. C., for appellee.
Before ROVER, Chief Judge, and HOOD and QUINN, Associate Judges.
QUINN, Associate Judge.
Appellant's car collided with one driven by Charles Menges, whom appellee had insured under a "$100 deductible" policy. According to the complaint Mr. Menges sustained damages to his car which required repairs costing $338.22. Under the terms of the policy appellee paid him $238.22. It then brought this suit as subrogee against appellant for that sum, and was awarded judgment. The sole contention urged on this appeal is that appellee's proof on the question of damages was incompetent because (1) it was not properly authenticated, and (2) it did not satisfy the requirements of the best evidence rule.
In order to prove damages,[1] appellee could show Mr. Menges' loss by introducing either the paid repair bill[2] or an estimate of the cost of repairs,[3] coupled with testimony as to the payment of such charge.[4] We have held that an itemized repair bill, coupled with oral testimony as to payment, was sufficient prima facie evidence of the amount of damages in the absence of any evidence casting suspicion on the transaction. Evidence must also be introduced of payment to the insured to establish the right of subrogation.[5] Appellee's evidence on these points was as follows:
It offered only one witness, Mr. Menges. He testified that the cost of the repairs necessitated by the accident was $338.22 and that he paid this amount to the repair company. In turn, appellee gave him a check in the sum of $238.22. According to the statement of proceedings and evidence, at this point appellee "introduced into evidence" a handwritten copy of a repair estimate, to which appellant objected on the ground that it was a mere estimate and not a paid bill. The objection was overruled. Appellee also offered photostatic copies of a sworn proof of loss and a release executed in its favor by Mr. Menges. Appellant then objected to all three of these exhibits on the grounds that they were not properly authenticated and that they did not "comply with the best evidence rule in that no foundation had been properly laid for the admissions of copies or photostatic copies of the individual documents." This objection was overruled and the exhibits accepted.
We shall treat the photostats of the proof of loss and the release initially. Appellant correctly points out that there was no evidence to show what had become of the originals and argues that without such preliminary evidence the documents were inadmissible. Appellee's position is that they were properly received by virtue of the Federal Shop Book Rule as records kept in the regular course of business.[6] We would *153 agree with this contention, since on their face these documents appear to comply with the rule, but for the fact that so far as we are able to determine, there was no actual evidence at the trial identifying the records as such. However, we do not regard these defects as serious here, because these exhibits were mainly used to show appellee's right of subrogation and this fact was proved by the testimony of Mr. Menges.[7]
The acceptance into evidence of the handwritten copy of the repair estimate presents a more serious question. Appellant challenges it on the ground that it was not properly authenticated and that it did not comply with the best evidence rule. We must agree that technically both contentions are correct. However, the record before us indicates that the only objection made at the time the copy of the estimate was introduced was simply that it was not a paid bill. Apparently the other objections were not raised until all the evidence had been offered. "It is within the discretion of the trial court to allow testimony, which is not the best evidence, to stand, where opportunity to object has existed but is not exercised until after the testimony is given."[8] In view of the tardy objection we cannot rule that its admission was an abuse of the trial court's wide discretion in these matters. Nevertheless, as the Supreme Court has said, in a comparable situation,
"* * * it may be conceded that a very large amount of discretion must be reposed in the trial court to whom such copy of a record is presented, in ruling upon the circumstances which shall determine its admission or rejection; and it is possible that, if there were no other objection to the proceedings at the trial than this one, this court would not reverse the judgment on that account, but it is certainly not good practice, nor an exercise of the discretion of the court to be commended."[9]
Affirmed.
