This action was brought for the recovery of damages alleged to have been sustained by the plaintiff while a passenger on one of the defendant’s cars, by reason of its negligence in operating the same. Verdict for the plaintiff for the sum of $9,500, and from an order granting a new trial the plaintiff appealed.
Upon the trial it was an important and disputed question whether or not the plaintiff’s then physical condition was caused by the injury she received on the car. The plaintiff called Dr. B. J. Merrill, who made an examination of the plaintiff, for the purpose of qualifying himself to testify as an expert, on the morning of the day he was called as a witness. To a question as to what in his judgment was the cause of the then present physical condition of the plaintiff (which was objected to by defendant, and an exception taken), he answered, “I can conceive that a severe injury might set up a train of symptoms which would result in the present condition.” The next question was, “And, in your opinion, did?” He answered, “My judgment, in view of the symptoms outlined by Dr. Marshall, is that it undoubtedly had a causative effect.” Upon his cross-examination he was asked the questions, and gave answers thereto, as follows: “Q. Then do I understand you, doctor, to say that your opinion that you have expressed is based entirely upon something-outside of her unsworn statement, or the statement of some one else? A. It is based on my examination and the testimony or the statement and the history of the case given by the attending physician, Dr. Marshall. Q. A statement made to you when? A. At the time I examined her. Q. That is, this morning? A. Yes, sir. Mr. Thygeson: Now I move to strike out the testimony of this witness *218for the reason that it appears to be based in part upon the unsworn statements of Dr. Marshall. The Court: The motion will be denied. Exception for the defendant.” The trial court granted the motion for a new trial for the reason that it erred in denying the defendant’s motion. Counsel for plaintiff urges two reasons why the order should be reversed:
First. That the motion was too broad, in that it included all of the testimony of the witness, a portion of which, as he claims, was undoubtedly competent.
Construing the motion technically, this claim is correct, but manifestly such is not its proper construction. It is evident that, by the word “testimony,” as used in the motion, reference was made to the testimony of the witness as to his opinion, and not to all of his testimony. This is apparent from the testimony which immediately preceded and was the inducing cause for making the motion, and from the reason assigned for making it, viz. “that it (the opinion) appears to be based in part upon the unsworn statements of Dr. Marshall.” It is obvious that the trial court so understood it, else a new trial would not have been granted for this reason. The motion was sufficiently specific to inform the court as to what evidence it referred.
Second. That the court did not err in denying the motion to strike out the evidence, for the reason that the opinion evidence was competent.
In support of this contention he relies upon the cases of Jones v. Chicago, St. P., M. & O. R. Co., 43 Minn. 279, 45 N. W. 444; Johnson v. Northern Pac. R. Co., 47 Minn. 430, 50 N. W. 473; Brusch v. St. Paul City Ry. Co., 52 Minn. 512, 55 N. W. 57; Cooper v. St. Paul City Ry. Co., 54 Minn. 379, 56 N. W. 42. These cases hold that a physician may give his opinion of the physical condition of a patient after an examination of him, although it is based in part on the statement of the patient, made at the time, as to his suffering and symptoms. Rogers, Exp. Test. § 47. The reason for this rule is that the physician must oftentimes of necessity take into consideration such statements in reaching a conclusion as to the physical condition of the patient and the nature and extent of his malady or injury. The rule must be applied with caution, and not extended beyond the reason and necessity upon which it rests. Ashland v. *219Marlborough, 99 Mass. 47, In the case at bar, the opinion objected to did not relate solely to the physical condition of the plaintiff, or the nature of her disease, but to the cause of her condition; and the statement upon which it ivas in part based was not that of the patient herself, but upon the statement and history of the case given by a third party when the witness examined the plaintiff. Clearly, the cases relied upon have no application to this case, where the opinion in part was based upon a mere narration of past events, made by a third party out of court and not under oath. It is settled beyond controversy that a medical expert cannot be allowed to give his opinion on information which he has obtained out of court from third parties' other than the patient. Rogers, Exp. Test. § 46. It follows that the evidence which the defendant asked the court to strike out was incompetent, and of a character well calculated to injure the defendant, and that the trial court erred in its riding whereby the evidence was permitted to stand for the consideration of the jury. The court having granted a new trial because of this error, and for the purpose of correcting it, we are of the opinion that it was authorized and fully justified so to do, in its discretion, if not legally bound to do 't.
Order affirmed.
