区际法律冲突,是指一个国家内部具有独特法律制度的不同地区(“法域”)之间的法律冲突,属于国内法的范畴。区际法律冲突的实践十分悠久,至今在许多国家仍是一个十分现实的问题,瑞士、德国、美国、加拿大、法国和波兰等都是各具特色的所谓“复合法域”国家。 Interregional conflict of laws refers to the legal conflicts between different regions (“jurisdictions”) within a country that have unique legal systems and fall under the category of domestic law. Interregional conflicts of laws have a long history of practice and so far they are still a very real issue in many countries. Switzerland, Germany, the United States, Canada, France and Poland are all characteristic so-called “composite jurisdictions.”
