Interpretacja postanowień konwencji międzynarodowych zawierających normy o charakterze cywilnoprawnym

International conventions governing civil-law relationships are established as a result of compromise between various legal systems. Their terminology, as well and the institutions regulated by them are not always coherent with those deriving from the domestic legal systems. Therefore, it is necessary to apply different rules of interpretation to this type of regulations. The purpose of the paper is to answer the question to what extent the rules of interpretation, in particular language interpretation, developed in the jurisprudence, may be applied to civil law regulations included in the international conventions. The paper also aims at determining in what measure the rules of interpretation of international conventions arising from the Vienna Convention on the Law of Treaties may be useful for the same purpose.
