15 Which of the following descriptions on the legal sources of private international law is NOT correct?
(A) The legal sources of private international law include treaties, international customs, legislation, and precedents.
(B) In common law countries, precedents have become the main source of private international law. On the other hand, in civil law countries which adopt statutory law, precedents are not regarded as a source of private international law.
(C) In order to resolve conflicts on the rules of private international law among various countries, international conferences have been held to achieve the goal of unifying private international law through international treaties since the 19th century. Therefore, treaties are an important source of private international law.
(D) International judicial institutions when they are dealing with private international law cases, if there is no treaty between the two parties and if their private international laws are not applicable, the general principles of private international law, such as the principle of lex rei sitae, and the principle of locus regit actum, are preferred because of their supranational nature.
