Press TV - Iran's ambassador to the United Nations says the UN Security Council is facing a legitimacy and credibility crisis that has to be addressed through reforms.

Majid Takht-Ravanchi made the remarks before a United Nations General Assembly meeting in New York entitled �Question of equitable representation on and increase in the membership of the Security Council and related matters."

The ambassador criticized the structure of the 15-member Council, which is mostly dominated by western countries and, arguing that it needs to be expanded in a balanced way.

"Geopolitically, the Council is dominated mostly by western countries, three of which have veto power, and geographically, while WEOG (the�Western European and Others�Group) is overrepresented, the main regions are poorly represented in terms of number and have less rights and privileges in terms of veto power or permanent membership," the envoy said in his speech.

"To date, one-third of UN members have never found a chance to become a Council member while there have been 20 countries that have each served between 10-22 years in this body," he said.

Takht-Ravanchi said this "disproportionality and injustice must be addressed and rectified", including by limiting chances for those who have served more and, instead, providing more advantages to those who have never served in the Council or served less times.

"This is essential in ensuring equal opportunities for all States to become a Council member as well as in preventing the domination of a certain regional or geopolitical group over the Council," he argued.

The ambassador said the Council�s reforms should ensure that its members decide based not on their own national interests but based on the common interests of the entire UN membership.

"The Council must also stop increasing the excessive and expeditious resort to its Chapter VII functions. For instance, it has imposed sanctions in situations where no action was even necessary," he said.

"Chapter VII must be invoked as a measure of last resort, if necessary," Takht-Ravanchi noted.

For several years, the Islamic Republic of Iran remained under sanctions based on a Resolution passed by the UN Security Council enacted under the Chapter VII of the UN Charter, until the Resolution 2231 endorsed the 2015 nuclear deal between Tehran and world powers, and took the country out of the Chapter VII.
