The Role of the Guardian Council in Ensuring Compatibility between Persian and Non-Persian Texts of International Treaties

In spite of the silence of the Constitution and the Guardian Council's Regulations regarding the Council's authority to oversee the compatibility of Persian and non-Persian texts of treaties, the council has returned some approved treaties to the parliament because the texts are inconsistent. The question that arises in this regard is to what extent the action of the council has been able to correct the Persian text of the treaties?
According to a preliminary study, the above action of the council resulted in the declaration of ambiguity in the parliament's enactments. Therefore, in this article, the council's declarations of ambiguity in regard to the compatibility of Persian and non-Persian texts of the treaties were examined and it turned out that out of 852 treaties reviewed by the council until the end of 1399, 12 treaties faced such ambiguity and the factors of ambiguity were: 1. Lack of treaty annexes, 2. Obscurity of some articles of the treaty, 3. Existence of provisions contrary to legal principles, 4. Editing, phraseology, spelling, and translation errors. These cases have been examined and most of them were found to be correct, so the parliament has corrected the enactments as a result of the errors raised by the council.
However, the council's worthy role was not without flaw in this respect, since in some cases its declaration of ambiguity did not hold true, and in other cases, despite the contradiction between the Persian and non-Persian texts of a treaty, the parliament's enactment was approved by the Guardian Council.
