Summary of the Judgment

1. In international legal relations, where a prerequisite issue indispensable for solving a issue of law (the present issue) constitutes another issue of law distinct from the present issue in terms of international private law, the applicable law for the prerequisite issue should be decided under the international private law of Japan, the venue of the trial.
2. In the case of examining the existence of foreign parent-child relation, where the legitimate parent-child relation is denied under an applicable law governing such legitimate parent-child relation, the applicable law should be applied to judge the existence of parent-child relation except for legitimate parent-child relation.
3. Under the rules concerning the application of laws before being revised by Law number 27 of 1989, the applicable law governing the existence of legitimate parent-child relation in the case of obtaining legitimacy based on reasons other than birth should be the law of the home country of the mother's husband at the time when the fact which should constitute the cause of obtaining legitimacy was achieved.
4. Under the rules concerning the application of laws before being revised by Law number 27 of 1989, the existence of parent-child relation except for legitimate relation between parties who are not related to each other by birth should be recognized if both the law of the parents' home country and the law of the child's home country at the time when the fact which should constitute the cause of establishing the said parent-child relation admit the existence of the said parent-child relation.
