Opinion
Plаintiff appeals from a judgment on a jury verdict in favor of defendant, Green Hills Country Club, in an action for personal injuries.
Facts
Prior to the time of the injury, appellant had been residing at 855 Hacienda Way in Millbrаe for approximately two months. He had been an active member of Green Hills Country Club for several years and was familiar with the layout of the golf course, particularly the fifth hole which is immediаtely adjacent to appellant’s residence. Before appellant moved into this home, he himself on many occasions had hit golf balls over the property lines of adjacent homes, including the property now owned by him. At the time the accident occurred, there was a 6-foot high grape stake fence separating appellant’s property from respоndent’s. When appellant purchased the home, he had some reservations concerning its safety. He spoke with members of respondent’s board of directors, who assured him that if he purchаsed the house, a fence would be erected so that he would be protected from golf balls. The protective fence was not in fact built until after the incident which caused appеllant’s injury. Subsequent to the erection of the fence, a screen 30 feet high;, balls which go over the screen usually strike the roof of the house.
After appellant moved into the home, conditiоns were such that he forbade his. family to use the yard and swimming pool until he arrived home at night, which was usually 6 or 7 o’clock. The swimming pool on appellant’s property runs generally in a direction рarallel to the fence. *504 From the fence it is possible to see the entire fifth hole, the fourth hole except the tee, and the fairway coming down the third hole. It is not possible to see thе third green.
On Saturday, July 9, 1966, at about 5 to 5:30 p.m., appellant was in the hack yard with his one-year-old daughter, wading in the pool. Appellant testified that he complied with his customary practice of looking out over his back gate to check if there were any golfers coming. He observed no golfers approaching. The number of golf balls coming on to appellant’s property was heaviest during the week end, but on Saturdays there was rarely anyone out after 4 p.m. because on Saturday players start very early. Appellant and his daughter were in the pool apprоximately 30 minutes when the accident happened. A ball was struck by Mr. Fowler, a member of respondent country club. His drive off the fifth tee was a slicing shot that ended up on the third green. The next shot went over some trees towards the fifth green. Appellant’s house was directly in line behind the trees. The ball struck and injured appellant.
Assumption of Risk
Appellant’s only claim of error is the giving of an instruction on assumption оf risk. The main thrust of his argument is that, while he had general knowledge of the danger caused by errant golf balls, he did not know of the particular danger which caused his injury because he was not aware of thе fact that there were golfers on the third hole at the time of the accident.
To warrant the application of the doctrine of assumption of risk, the evidence must show that the injured pаrty appreciated the specific danger involved. He must have not only general knowledge of a danger, but also knowledge and appreciation of the particular danger аnd the magnitude of the risk involved.
(Vierra
v.
Fifth Avenue Rental Service,
Respondent answers this proposition by saying, first, that when appellant checked to see if anyone was playing, Fowler could have been in the vicinity of that part of the third hole which was outside appellant’s view, and the jury could have found that what respondent cаlls the “so-called precaution" would not relieve appellant from assuming the risk. But if there was negligence in the matter of inspection of the golf course by ap
*505
pellant, this would fall under the heading of contributory negligence and not of assumption of risk. “[Plaintiff’s] failure to exercise ordinary care to discover the danger is not properly a matter of assumption of risk, but of the dеfense of contributory negligence.” (Prosser on Torts (3d ed.) p. 462;
Ward
v.
Knapp,
It is true that actual knowledge of the risk and appreciation of its magnitude are subjective requisites which are rarely susceptible of proof by direct evidence. A plaintiff need not be believed by the trier of fact simply because he testified that he did not know or appreciate that which was obvious, But in the case before us, there is no evidence to show that plaintiff must have known that a golfer actually was aрproaching, nor was there any evidence to contradict plaintiff’s to the effect that at the hour when the accident occurred on a Saturday, golfers were rarely to be seеn on the course. If plaintiff had testified falsely, impeaching testimony should not have been difficult to produce.
Finally, we remark that the doctrine of assumption of risk should not be applied with liberаlity, if it be applicable at all, where the injury takes place on plaintiff’s own property, which in itself is safe and which is rendered dangerous only by invasion of missiles from adjacent land. Otherwise, the оwner of the neighboring property could force the homeowner to remain out of his yard and his swimming pool during hours when it was possible that golfers might hit their shots on to his property. To a limited extent he wоuld be a prisoner within his home. Indeed, if the “within the range of possibilities” proposition were valid and applicable, appellant *506 would be vulnerable to assumption of risk if he ventured outside his home to the rear facing the golf course, until he had assured himself almost to the point of certainty that the last golfer had gone by. Moreover, if this were the law, there would be no particular rеason for the defendant to remedy the situation, unless it were moved by humanitarian reasons, because the rule of assumption of risk would be a continuing one operating for the defendant’s protection.
“In general, the plaintiff is not required to surrender a valuable legal right, such as the use of his own property as he sees fit, merely because the defendant’s conduct has threatenеd him with harm if the right is exercised.” (Prosser on Torts (3d ed.) § 67, p. 466; see also Rest.2d Torts, § 496 E, p. 576;
Rostant
v.
Borden,
We conclude that it was error to give the instruction.
Prejudicial or Nonpre judicial Error
We conclude that the error was prejudicial. In the first place, the instruction is not merely one of a series on a рarticular subject. It sets up a whole defense, which, if established, is a perfect one. In the second place, the words “assumption of risk” have about them the suggestion of an easy solution of the case. Finally, the defense of assumption of risk, if sustained by the necessary elements, will bar recovery of damages, although it plays no part in causing the accident except merely to expose the person to danger.
