Opinion by
On June 17, 1960, and for some time prior thereto, the appellee engaged in building a ramp to Interstate Route 80. The ramp adjoined the lawn areа on the south side of appellants’ house and lot. In constructing the ramp, appellee broke large rocks by use of a crane which liftеd and dropped an 8000-pound steel ball from heights as high as 25 feet. The operation caused vibrations to appellants’ house and threw pieces of rock onto their house and lawn. On June 17, 1960, the husband-appellant heard and felt a crash and ran out of his house to investigate. He clаimed that he fell to the ground as the result of having been struck on the head by a rock. He suffered a cut on his forehead and broke his false teeth.
Appellants brought suit in trespass against appellee on two counts. The first count was for damage to the real estate, and the second wаs for the husband’s injuries. The jury returned verdicts for the appellants on both counts. Appellants’ motions for new trial were refused and husband- appellant appeals from the judgment entered on his count for personal injuries, claiming inadequacy and errors in the charge.
The husband’s verdict was $395. Treаtment of his head wound, including x-ray, and repair of his den
An examination of the lower court’s charge, however, reveals a number of errors of law on causation and damage which require us to grant a new trial. We will reverse the lower court’s discretion in granting or refusing a new trial where there was an error of law which controlled the outcome of the сase. Izzi v. Philadelphia Transp. Co.,
The major damages claimed by the husband for his personal injuries were based on aggravation of the existing ulcer. If proven to have bеen caused by the blow to the head, it is clear that the husband can recover for such aggravation. As was said in Heck v. Beryllium Corp.,
The issue of other causes of the aggravation оf the ulcer was injected into the case. It was suggested in the testimony that the aggravation might have been caused by the stress of other matters in connection with the road construction since July 1960 rather than by the blow on the head. Thus it became necessary for the court to charge the jury on сoncurrent causes.
In the course of its charge, after explaining that the plaintiffs must show that the defendant’s action was the proximate cаuse of the injury, the lower court said: “If it is established that the facts complained of were the substantial cause of the injury, then it is said to have been the proximate cause, unless there was a contributing cause without which the event would not have happened.” This was incorrect because such a contributing cause “does not relieve the defendant from liability unless defendant shows that such other cause would have produced the injury complained of independently of his negligence.” Menarde v. Philadelphia Transp. Co.,
There may be two or more substantial causes which combine to cause an event and, if thе defendant’s negligence was one of those, the plaintiff may recover al
We find no merit in the other objections made by the appellants to the court’s charge, and the refusal
Appellants ask that a new trial be granted limited to damages. The appellee, however, contests the issue of liability, claiming that the husband in his testimony never said that he was hit on the head by a stone. Since the appеllee does not concede liability, and;liability is not so clear that reasonable men could not differ on it, we will not limit the new trial. See Rosen v. Slough, 212 Pa. Superior Ct. 398,
Judgment on the second count is reversed and a new trial granted.
