就外國法之適用範圍及其舉證責任分配,本文回顧臺灣關於民事訴訟法第283 條之相關學說見解及實務裁判,並考察日本法上之發展。本文主張,民事訴訟法第283 條所稱之「外國法」應為「非法庭地規範」。本條之適用範圍,非僅限於以外國法為準據法之情形,於內國法之「法律解釋」或「法之續造」,亦有適用或類推適用餘地。關於法院與當事人之間就外國法之舉證責任分配,應依事件類型或個案具體情形妥適決定之。
This article generally reviews several decisions of Taiwan Supreme Court and relative opinions of domestic scholars with regard to the burden of proof and applicable scope of foreign laws in civil procedure, and mainly observes the development of Japanese civil procedure law as the subject of comparative law research. Based on those references mentioned above, this article argues that "foreign laws" of article 283 of civil procedure law of Taiwan should include international civil and commercial principles. Besides, applicable scope of article 283 of civil procedure law of Taiwan should include conditions that whenever the law of a foreign State is applicable, It should also apply to "explanation" and "continued development" of domestic laws. The burden of proof of foreign laws between judges and parties should depend on different types of cases or concrete situations.
