Introduction
Arend, Anthony, and Robert argue that one of the major achievements of the United Nations was the creation of a body for international law. International law encompasses treaties and standards, and conventions. The international law plays a major role in promoting socio-economic development t as well as promoting international peace and security. Most of the treaties that were ratified through the United Nations establish the basis the law that governs or controls how different nations relate with one another. Despite the perceived peaceful existence and cohesion that the United Nations through international laws, some scholars have questioned legitimacy, authority, and legality of the UN.[Arend, Anthony Clark, and Robert J. Beck. International law and the use of force: beyond the UN Charter paradigm. Routledge, 2014.] [Binder, Martin, and Monika Heupel. "The legitimacy of the UN Security Council: Evidence from recent General Assembly debates." International Studies Quarterly 59, no. 2 (2015): 238-250]
Based on that background, the paper would, therefore, seek some three questions that would help in understanding the legitimacy, authority, and legality of international law and the United Nations.
The Main Justifications for the Legitimacy, Authority, and Usefulness of the UN
The debate about the legitimacy, authority, and usefulness of the United Nations has been there since the interception and establishment of the body. Some scholars are from the school of thought that the UN is a legitimate and useful body. On the other hand, there are those scholars who are from the school of thought that the UN body is illegitimate, and has no use. However, it is worth noting that legitimacy is a dimensional concept that means different things to different people. According to Buchanan, refers to the belief that is harbored by people that a law or institution, which should be obeyed. Most importantly, the idea of legitimacy is a subjective matter that is held in the actors’ mind, and ought not to be shared with others; this means that legitimacy has no universal meaning. There are various dimensions of the UN’s legitimacy and authority; however, for purposes of this paper, the author would discuss the two dimensions of the legitimacy of actions taken by the United Nations. These two dimensions of UN legitimacy include Legitimate use of force to restore peace backed by law and Normative Legitimacy for using Force.[Binder, Martin, and Monika Heupel. "The legitimacy of the UN Security Council: Evidence from recent General Assembly debates." International Studies Quarterly 59, no. 2 (2015): 238-250.] [Teson, Fernando. A philosophy of international law.Routledge, 2018.] [Yunker, James A. The Idea of World Government: From ancient times to the twenty-first century. Routledge, 2011]
To begin with the legitimate use of force by the UN legally; Buchanan is of the argument that the UN normally applying for to restore peace in any nation is backed by law. As a matter of there is a legal framework that supports the United Nations through its Security Council to forcefully deal with any situation that is deemed to be a threat to the world’s peace. The UN Charter has properly provided for the framework of rules that governs the use of force. Tesoneluci dates that the Preamble of the UN Charter has highlighted the fundamental function of the organization, which is basically to ensure international security and peace. This justifies the instances where the UN has intervened in war-prone countries like Iraq and Syria. Also, Chapter One (Article 1.1) of the UN Charter provides the specific guidelines and principles that govern the actions taken by the international organization to restore peace and ensure security in a country where there is war. For instance, in 1994, the UN via the Security Council sent its forces to Rwanda to restore peace in that country.[Binder, Martin, and Monika Heupel. "The legitimacy of the UN Security Council: Evidence from recent General Assembly debates." International Studies Quarterly 59, no. 2 (2015): 238-250.] [Arend, Anthony Clark, and Robert J. Beck. International law and the use of force: beyond the UN Charter paradigm. Routledge, 2014.] [Yunker, James A. The Idea of World Government: From ancient times to the twenty-first century. Routledge, 2011.]
Thakur posits that the system that was established in the UN Charter has two main parts that guide ensuring peace and security in the world. The first part, which is repressive, parts use of power by the UNSC as stated in (Chapter VII), and the second part, which provides for preventive measures and peaceful means restoring peace as stated in (Chapter VI) of the charter. It is important to note that it is the UN Security Council and General Assembly that are in charge of ensuring peace and security in the world. Roles played by both the UN General Assembly and the Security Council are provided for in Article 24.1 of the UN Charter .[Yunker...
