The Impact of Abuse of Proceedings and Rights in Preliminary and Substantive Proceedings in ICSID

The institution of good faith is not seriously considered in Iranian domestic law, and it seems that one of the important necessities for achieving justice and generalizing fair proceedings is to pay attention to this principle in the field of legislation, judicial procedure and arbitration. This institution is fully recognized in international law. ICSID is one of the most important international arbitration bodies in disputes arising from international investment. The role of ICSID in international investment protection against invested governments has been defined. Access to this important arbitration body is not possible except through good faith. Therefore, breach of good faith is considered as one of the obstacles to gaining this support. In this research, which has been done in a descriptive-analytical manner and by referring to the awards issued by ICSID, we seek to answer the question of what effect the violation of good faith by the investor will have on the preliminary and Merits proceedings. As a result, the hypothesis of the negative effect of malice on the ICSID procedure was confirmed in such a way that in the preliminary stage it will cause inadmissibility and in the Merits stage it will cause disenfranchisement.
