Investigating the authenticity of al-fassaad and hygiene in concluding contracts (in the form of an official document

The matters of ignorance and mistakes in Articles 199, 200, and 201 of the Criminal Code and Article 223 of the Criminal Code are related to the principle of authenticity. The claim that ignorance and mistakes in the appearance of his word are always contrary to the principle of authenticity in transactions. On the other hand, the principle of the practice of transactions is from the viewpoint of the jurisprudents of 'Ayalah al-Fasad', that is, whenever there is a transaction on the outside and there is doubt about the intention of the contract for the reason of the interlocutor's ignorance and mistake, or one of the two in the order of the purpose of the contract. The jurists in this transaction have been subject to the lack of transfer, and the result is corruption and the failure of this transaction. How can the two conflicting principles be gathered? In analyzing this, the principle of accuracy is defined in the notion of a state of affairs, not between duties, between the rules of law and the subject, or, in other words, the jurisprudential and principle issues. In the sequence of the text of the Quranic verses, the principle of authenticity is discussed from the point of view of the jurists, and the principles of authenticity in this regard have been accepted. The principle of authenticity has been accepted in all the conditions, including the fixed and non-binding, and the contract (formal documents), and its relation In accordance with the principle of being or contrary to the principle of the claim of ignorance and mistakes, the other results of this article are the priority of the Islamic Revolution as conflict with other principles, such as statute and subject matter. Hence, when it comes to the suspicion of the truth and corruption of the actions of others, other than that, the priority of the Islamic law is established on Isla'ah al-Fasad, whether the source of the corruption of the marriage is the claim of ignorance and mistake, or not.
