A Comparative Study of Trickery, Examples and Ways to Deal with it in Imamiya Jurisprudence and Iranian and French Law

A trick in jurisprudence means to achieve the desired religious legal and legitimate goal; whether the way to reach it is halal or the said way is religiously illegitimate. In the term of Iranian law, it means the ability to use the silence or summary of the law in order to acquire rights for the unjust in ways that are against the nature of the law, and in the term of French law, it means a shrewd act in which, by using the hidden defects of the law, a person seeks to perform a seemingly legal act. These different definitions have caused differences in examples of trickery and of course the solutions to deal with it. The present study is carried out through a descriptive-analytical method and tries to answer questions such as "What is the trick, examples and solutions to deal with it in Imamiya jurisprudence, Iranian and French law?" Examples of trickery in Imamiya jurisprudence are divided into three categories: Examples of real positive and legitimate tricks; examples of real negative and reprehensible tricks; Examples of formal tricks. Examples of tricks in Iranian and French laws can be divided into two parts: examples of tricks that violate formal laws and examples of tricks that violate substantive laws. In Imamiya jurisprudence, there is no countermeasure for permissible tricks, but two solutions are proposed for haram (forbidden) tricks including the moral solution that means piety and the jurisprudential solution which means ruling on being haram (forbidden). The solutions to deal with trickery in Iranian law are the theory of motive or direction; the theory of good faith; the theory of preventing the abuse of the right; the theory of public order; the principle of compliance of the contract with the intention; the base of the arms; the principle of Sad Zaraye (avoiding doing harms), the principle of “Yu’amil al-Mukalaf bi Naqiz Maqsoudah”. Regarding the solutions to deal with trickery in French law, it is possible to refer to the strategies including implementing the laws of the European Union, establishing various institutions to fight trickery and fraud, identifying points covered by the law by digital technologies, determining case and subject laws, determining the punishment in the criminal laws.
