Article 3 of the Guarantee of Automobile Accident Compensation Act intends to bear loss from the operation control of a motor vehicle and operation interest to a person who has the operation control over the motor vehicle and the operation interest based on the risk liability and the principle of compensation liability. Thus, the term "person who operates the motor vehicle for his own sake" refers to a person who is in the position of a responsible subject to the control over the operation of the motor vehicle and enjoying the benefit therefrom (see Supreme Court Decision 86Meu556, Dec. 23, 1986). The accident in this case occurred after the non-party 1, who is the driver of the motor vehicle, retired his employees and returned to the construction site of the defendant company. Thus, in light of the situation of the operation of the motor vehicle in this case, the defendant company, as the owner of the motor vehicle, cannot be deemed to have lost the operation control and the operation interest of the motor vehicle in this case.

In this view, the decision of the court below that recognized the defendant liable for damages arising from the accident under the Guarantee of Automobile Accident Compensation Act is just and there is no error of law such as the theory of lawsuit.

The Supreme Court precedents are different from those of the instant case, and are not appropriate for the instant case.

In addition, in light of the records, the court below determined that the degree of negligence of the deceased was 30 percent by comparing the non-party 1's driver's negligence which caused the accident of this case with the degree of negligence of the deceased. In light of the records, the court below's measure is just and acceptable, and there is no error of law by misunderstanding the legal principles of comparative negligence, such as theory of lawsuit.

All arguments are groundless.

Therefore, the appeal is dismissed, and the costs of the appeal are assessed against the losing party. It is so decided as per Disposition by the assent of all participating Justices.
