The Role of Customary Law in the Determination of the Domain of Instances of Causality According to Jurisprudence

"Causality" is considered as a kind of waste. Contrary to the assistance in the crime, in causality the causer causes the realization of loss or crime indirectly. The definitions of causality provided in the jurisprudence and law are rooted in the jurisprudence which is compiled and organized according to the received traditions. Some believe that the customary law has a particular and determinant role both in the basis and the identification of the instances of causality and that traditions indicate such a customary law. However, the customary law not only is not a reason for the principle of causality but also its instances cannot directly determined through mere correctness of referring to the causality by the customary law.Having determined the domain of the customary law and analyzed it role in this principle, the present paper determines the role of customary law in this principle through analytical method and library survey.
