, DEVELOPMENT, NATURE AND SCOPE OF INTERNATIONAL
LAW
International law is ‘a system of rules and principles that govern the
international relations between sovereign states and other institutional
subjects of international law’ Dixon et al 2007
The United Nations Charter states fundamental principles of international law
that all UN members must abide by in Article 2
o The organisation is based on the principle of the sovereign equality of all its
members
▪ Sovereignty imports the idea of independence that
international law relies on
▪ This is known as a horizontal system of sovereignty
o All members, in order to ensure to all of them the rights and benefits
resulting from membership, shall fulfill in good faith the obligations
assumed by them in accordance with the Charter
o All members shall settle their international disputes by peaceful means
in such a manner that international peace and security and justice are not
endangered
o All members shall refrain from the threat or use of force against the
territorial integrity or political independence of any State
o All members shall assist the UN in any actions It takes, and shall refrain
from giving assistance to any state against which the UN is taking
preventive or enforcement action
No state may compel another to submit to judicial settlement of a dispute between
them and no state is bound by an international rule unless it has first consented
o This is reflected in the UN through the voting system, where Iceland has
the same 1 vote as China or the USA.
There is some tension between the sovereignty of every state and the obligations of
human rights – when can one interfere to protect human rights in another state?
Organs of the United Nations include
o The General Assembly – All states have an equal vote, and decisions
require a two thirds majority
▪ Where action is required it must be referred to the security
council
o The Security Council – 5 permanent members, with 15 members
overall. Decision require 9 votes including those of the permanent
members
o International Court of Justice (ICJ) – the principle judicial organ of
international law. All members of the UN are ipso facto parties to the
Statute of the Court.
HISTORY
International law is extremely old, dating back to Kings and empires that
negotiated treaties as early as 3000BC
