Abstract
The legislator has determined the punishment for the crime and the violation of the norms, and sometimes it escalates regardless of its amount and quality, a severity that is always necessary to support the social order. Intensification of punishment as one of the components of the principle of personality of punishment and the practical and challenging application of general criminal law has various general and special causes. One of the common causes of this issue is the multiplicity of credits that the legislator has dealt with in Article 131 of the Islamic Penal Code (approved in 2012). Now, due to the importance of the discussion of pluralism in criminal law, its many results and not belonging to a specific crime, the present research, while examining this important issue and explaining its various dimensions, has addressed the challenges that have arisen in order to implement the regulations of this institution. And he has expressed solutions to get out of them. The main question of the article is what are the practical challenges that can be faced by the multiplicity of credit institution and what solutions can be offered to overcome these challenges? Since the multiplicity of the result also has similarities with the multiplicity of credit in terms of rulings, in the second part of this article, we have analyzed the multiplicity of the result and its ambiguities in a descriptive and analytical way.
