INTRODUCTION TO PUBLIC INTERNATIONAL LAW

This introduction is written to provide students with an overview of international law I at the outset of their study so that they can understand the

structure of the international legal system and the principles governing the main topics before they begin a detailed study of any topics. This document only discusses the general principles. In many cases it oversimplifies international law by summarizing it in less than one page what is covered in an entire chapter in an international law textbook. However, it is hoped that it will give students an overview of the major topics and principles so they can better understand how the particular chapters or topics fit or link together. 

B.       Definition of International law

International Law consists of the rules and principles of general application dealing with the conduct of States and of international organizations, and with their relations with each other, as well as with some of their relations with private individuals, minority groups and transnational companies. Put simply, international law is simply the set of rules that countries follow when dealing with each other. It also serves as a framework for the practice of stable and organised international relations.

 

C.       International Legal Personality

International legal personality refers to the entities or legal persons that can have rights and obligations under international law. Some of the international personalities under international law include:

 

1.         States

A State is an entity with the following characteristics:

 

(1) a permanent population;

(2) a defined territory;

(3) a government; and

(4) the capacity to enter into relations with other States. 

(5) independent of the authority of any other state

 

Many writers argue that a State must also be independent of the authority of any other State. Some writers also argue that an entity is not a State until it has been recognized as such by other States (however there is continued debate on how such recognition is done); even though it is admitted that recognition is a political rather than legal act. A State is the term used in international law, although the terms - nation states, nations and countries are also used on occasion.

 

The international legal system is a horizontal legal system dominated by States. States are in principle considered as being sovereign and equal. International law is predominately made and implemented by States. Only States can have the following privileges:

 

(1) sovereignty over territory,

(2) become members of the United Nations and other international organizations,

(3) have access to the International Court of Justice to settle their disputes.

(4) become parties to treaties.

 

2.         International Organizations

International Organizations are established by States through international agreements for particular purposes. They have only such powers as are conferred on them by States in their constituent document. International organizations have a limited degree of international personality, especially vis-à-vis member States. They can enter into international agreements and their representatives have certain privileges and immunities. The constituent document may also provide that member States are legally bound to comply with decisions on particular matters.

 

The powers of the main political and legal organs of the United Nations are set out in the United Nations Charter- 1945. The main political organ, the UN General Assembly, is not a world legislature. The authority of the UN General Assembly on most matters (such as human rights and economic and social issues) is limited to discussing issues and making recommendations. The Security Council has the authority under the United Nations Charter to make decisions that are binding on all member States when it is performing its primary responsibility of maintaining international peace and security. 

 

The main UN judicial organ is International Court of Justice (ICJ), which has the power to make binding decisions on questions of international law that have been referred to it by States.  However, the ICJ can hear only cases in which States have consented to its jurisdiction. 

 

3.         Nationality of individuals, companies, etc.

Private individuals are generally not regarded as legal persons with rights and duties under international law. Their link to a State is through the concept of nationality, which is often referred to under domestic law as citizenship. Nationality is the status of being treated as a national of a State for particular purposes. Under international law, each State has wide discretion to determine which individuals should be considered its nationals. The most common methods of acquiring nationality are at birth where one or both parents and/or by the place of birth. Nationality can also be acquired by adoption and naturalization. Nationals of a State carry a travel document called a passport when they travel from one State to another State. 

 

Companies, ships, aircrafts and spacecrafts are usually considered under international law as having the nationality of the State in whose territory they are registered. This is important because in many circumstances States may have international obligations to regulate the conduct of their nationals, especially if they are carrying out act activities outside their territory.


Under the principle of nationality of claims, if a national is injured by another State through conduct that is not consistent with international law, the State may make a claim against the other State on behalf of its injured national. This is known as the doctrine of diplomatic protection.

 

D.       Sovereignty of States over Territory

Sovereignty is the exclusive right to exercise supreme political authority (legislative, judicial and executive) over a defined territory and the people within that territory. Since it is the exclusive right, it means that no other State can have formal political authority within that State. Therefore, sovereignty is closely associated with the concept of political independence. 

 

States have sovereignty over their land territory and over the airspace above their land territory. The land territory includes off-shore islands if they are naturally formed areas of land which are above water at high tide. States also have sovereignty in a belt of sea adjacent to its coast called the territorial sea, as well as the air space above the territorial sea and the seabed and subsoil below the territorial sea. However, the sovereignty of States over their territorial sea is subject to limitations. For example, ships of all States have the right of innocent passage through the territorial sea.

 

Classical international law developed doctrines by which States could make a valid claim of sovereignty over territory. The doctrines included discovery and occupation and prescription. During the period of Western colonial expansion new territories and islands were subject to claims of sovereignty by discovery and occupation. Sovereignty could also be transferred to another State by conquest (use of force) or by cession. If the Western colonial powers recognized a ruler in an overseas territory as the sovereign, they would often enter into a treaty of cession with the ruler by which sovereignty over the territory would be ceded in to the Western colonial power. Problems often developed because the people in those territories did not understand the concepts of sovereignty and cession.

 

Since a State has sovereignty over its territory, the entry into its territory by the armed forces of another State without consent is a prima facie breach of international law, and often will be interpreted as an act of aggression. Among the attributes of sovereignty is the right to exclude foreigners from entering the territory, which is traditionally referred to as the right to exclude aliens. Since a State has sovereignty within its territory and territorial sea, it has the exclusive authority to exercise police power within its territory. Therefore, if foreign ships are attacked by “pirates” in the territorial sea of a State, the only State that can exercise police power and arrest the pirates in the territorial sea is the coastal State.

 

E.       International Obligations (Sources of Law)

As international law developed, it became accepted that the sources of international law were treaties, custom and general principles of law. It is generally accepted that the sources of law are listed in the Article 38(1) of the Statute of the International Court of Justice, which provides that when deciding disputes submitted to it in accordance with international law, the Court shall apply:

 

a)            International conventions, whether general or particular, establishing rules expressly recognized by the contesting states;

b)            International custom, as evidence of a general practice accepted as law;

c)      The general principles of law recognized by civilized nations;

d)           Subject to the provisions of Article 59, judicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law.

 

1.         Treaties

The reference in paragraph a) to international conventions refers to treaties. Treaties are written agreements between States that are governed by international law. Treaties are referred to by different names, including agreements, conventions, covenants, protocols and exchanges of notes.  If States want to enter into a written agreement that is not intended to be legally binding under the law of treaties, they often refer to it as a Memorandum of Understanding and provide that it is not to be governed by international law. Treaties are sometimes classified as either bilateral or multilateral. They can also be classified as bilateral, regional and global. 

 

The law of treaties is now set out in a global convention, the 1969 Vienna Convention on the Law of Treaties. The 1969 Vienna Convention sets out the basic principles of treaty law, the procedures for how global treaties become binding and enter into force, the consequences of a breach of treaty, and principles for interpreting treaties.

 

The basic principle underlying the law of treaties is referred to by the Latin phrase pacta sunt servanda -which means that every treaty in force is binding upon the parties to it and must be performed by them in good faith. 

 

The other important principle is that under the law of treaties, the provisions in treaties are binding only on States parties. They are not binding on third States without their consent.  However, it may be possible for some or even most of the provisions in an international convention to become binding on all States as rules of customary international law. This will be explained in the next section.

 

There are now global conventions covering most major topics of international law. Such conventions are open to all States and are usually adopted at an international conference and opened for signature. Treaties are sometimes referred to by the place and year of adoption, e.g. the 1969 Vienna Convention.  If a State becomes a signatory to such a treaty, it is not bound by its provisions, but it undertakes an obligation to refrain from acts which would defeat the object and purpose of the treaty. 

 

A State expresses its consent to be bound by the provisions of a treaty when it deposits an instrument of accession or ratification to the official depository of the treaty. The United Nations Secretary-General is often the official depository. If a State is a signatory to an international convention, the formal document it sends to the depository is called an instrument of ratification.  If a State is not a signatory to an international convention but decides to become a party, the formal document it sends to the official depository is called an instrument of accession.  The legal effect of the two documents is the same.

 

A treaty usually enters into force after a certain number of States have expressed their consent to be bound through accession or ratification. Once a State has expressed its consent to be bound and the treaty is in force, it is referred to as a party to the treaty. The general rule on the interpretation of treaties is that it shall be interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in light of its object and purpose. As supplementary means of interpretation, recourse may be had to the preparatory work of the treaty and the circumstances of its conclusion. The preparatory work is usually referred to by the French term travaux préparatoires.  

 

2.         Custom

Paragraph b) of Article 38 (1) (b) refers to “international custom, as evidence of a general practice accepted as law”. It has also been described as a constant and uniform usage among States which is accepted as law. Rules of customary international law, sometimes referred to general international law, are in principle binding on all States.

 

If a dispute arises between two States over the existence of a rule of customary international law, the State alleging the existence of the rule has the burden of proving its existence. This is done by showing a consistent and uniform practice among States, including those States specially affected by the rule or having the greatest interest in the matter. For example, to examine the practice of States on military uses of outer space, one would look in particular at the practice of the space powers, especially the super powers.  

 

In addition to constant and uniform usage or practice, some ICJ cases suggest that the State attempting to prove the existence of the rule must also present evidence of a second element called opinio juris – this is the belief by States following the particular practice or usage that such practice or usage is required by international law. In theory the concept of opinio juris creates a serious obstacle to any State attempting to prove the existence of a rule of customary international law because it is extremely difficult to find evidence of the reason why a State followed a particular practice of usage. 

 

However, in practice the problem is usually not as great as it seems. If a particular practice or usage is widespread, and there is no contrary State practice proven by the other side, the Court often finds the existence of a rule of customary international law.  It sometimes seems to assume that opinio juris was satisfied, and it sometimes fails to mention it. Therefore, this writer’s view is that what is most important in proving the existence of a rule of customary international law is finding consistent State practice, especially among the States with the most interest in the issue, with minimal or no State practice to the contrary. 

 

Over hundreds of years States uniformly followed practices in their relations with one another such as:

 

(a) Giving foreign diplomats in their territory immunity from their criminal laws;

(b) Treating foreign diplomatic premises in their territory as inviolable;

(c) Recognizing the right of innocent passage of foreign ships in their territorial sea;

(d) Recognizing the exclusive jurisdiction of the flag State on the high seas;

(e) Ordering its military authorities to respect the territorial boundaries of neighboring States; and

(f) Protecting non-combatants such as civilians and sick or wounded soldiers during international armed conflict. These usages or customs came to be accepted as legally binding. Hence they are referred to as rules of customary international law.

 

3.         General Principles of Law

Paragraph c) of Article 38 (1) refers to General principles of law recognized by civilized nations are often cited as a third source of law. They are principles that can be applied by courts or tribunals in decided cases on issues of international law. The principles are general principles that apply in all major legal systems of the world. An example would be the principle that persons who intentionally harm others should have to pay compensation or make reparation. 

 

General principles of law are usually referred to by courts or tribunals when they must decide a legal dispute between two States, and no treaty provision or clear rule of customary international law exists. In such cases, the Court may fill the void by turning to general principles of law that exist in the major legal systems in the world. 

 

4.         Subsidiary for the determination of rules of law

Paragraph d) of Article 38 (1) lists subsidiary means for the determination of rules of law. Subsidiary means are not sources of law. They are subsidiary means or evidence that can be used to prove the existence of a rule of customary international law or a general principle of law. 

 

Article 38 lists only two subsidiary means, (i) the teaching of the most highly qualified publicists and (ii) judicial decisions. The first phrase is antiquated language that refers to the writings of scholars who are experts in international law. The second phrase can mean judicial decisions of international courts or tribunals. Judicial decisions could also include decisions of the highest national courts if they are ruling on issues of international law.

 

If highly qualified publicists are referred to try to prove the existence of rule of customary international law, eminent scholars of international law should be cited, not articles written by a student author or a book publishing the PhD thesis of a young scholar. 

 

Resolutions of the UN General Assembly or resolutions adopted at major international conferences are only recommendations and are not legally binding. However, in some cases such resolutions may be subsidiary means for determining rules of customary international law. The weight of such resolutions as evidence of rules of customary international law depends upon their wording, the circumstances of their adoption, and whether they have been adopted by consensus or without negative vote. If the resolution purports to declare a set of legal principles governing a particular area, if it is worded in norm creating language, and if is adopted without any negative votes, it can be evidence of rules of custom, especially if States have in practice acted in compliance its terms after the resolution was adopted.

 

Examples of UN General Assembly Resolutions which have been treated as strong evidence of rules of customary international law include the following:

 

·         GAR 217A Universal Declaration of Human Rights (1948)

·         GAR 1514 Declaration on the Granting of Independence to Colonial Territories and Peoples (1960) [Declaration on De-Colonization]

·         GAR 1962 Declaration of Legal Principles Governing Activities of States in the Exploration and Use of Outer Space (1963)

·         GAR 2131 Declaration on the Inadmissibility of Intervention in the Domestic Affairs of States and the Protection of their Sovereignty (1965) [Declaration on Non-Intervention]

·         GAR 2625 Declaration on Principles of International Law Concerning Friendly Relations and Cooperation among States in Accordance with the Charter of the United Nations (1970) [Declaration on Friendly Relations]

·         GAR 1970 Declaration of Principles Governing the Sea-Bed and the Ocean Floor, and the Subsoil thereof, Beyond the Limits of National Jurisdiction

·         GAR 3314 Resolution on the Definition of Aggression

 

Some of these resolutions have also been treated as subsequent agreement or practice of States on how the principles and provisions of the UN Charter should be interpreted.

 

In addition, writers have argued that Article 38 fails to take into account the norm-creating effect of modern global conventions. Once the international community has spent several years drafting a major international convention, States often begin in practice to refer to that convention when a problem arises which is governed by the convention. In such cases, the provisions in such a convention can become evidence of the rules of customary international law. 

 

Furthermore, if the Convention becomes universally accepted, and the parties include the States with the most interest in the matters governed by the Convention, the provisions in the Convention may become very strong evidence of the rules of custom, especially if States which are not parties have also acted in conformity with the Convention. The stage can be reached where the convention provisions are regarded as binding on all States under customary international law, unless there is State practice to the contrary. An example of such a convention would be the 1959 Vienna Convention on Diplomatic Relations, the 1969 Vienna Convention on the Law of Treaties, and the first ten Parts of the 1982 United Nations Convention on the Law of the Sea.

 

5.         Hierarchy of norms

In theory there is no hierarchy among the three sources of international law listed in Article 38 (1) of the ICJ Statute. In practice, however, when examining a dispute between two States, international advisors usually look first to any applicable treaty rules, then to custom, and last to general principles. Since treaty rules are the most clear and certain, they are always the starting point.

 

Also, there are two types of norms or rules which do have a higher status.  First, peremptory norms (principles of jus cogens) are norms that have been accepted and recognized by the international community of States as so fundamental and so important that no derogation is permitted from them. Under the law of treaties, a treaty between States which conflicts with a principle of jus cogens is void. Examples of jus cogens principles are a war of aggression and genocide. A war of aggression is the use of armed force to take over another State or part of its territory. A modern example of a war of aggression would be the 1990 invasion of Kuwait by Iraq for the purpose of annexing Kuwait and making it part of Iraq. Genocide is the killing or other acts intended to destroy, in whole or in part, of a national, ethnical, racial or religious group.

 

Second, members of the United Nations are bound by the Article 103 of the United Nations Charter, which provides that in the event of a conflict between the obligations of members under the UN Charter and their obligations under any other international agreement, their obligations under the UN Charter prevail. Therefore, when the UN Security Council acts under Chapter Seven in performing its responsibility for maintaining international peace and security, its decisions to impose economic sanctions are binding on UN members and such decisions prevail over conflicting obligation in other international agreements.

 

6.         Role of the International Law Commission

The International Law Commission (ILC) was established by the United Nations in 1948. The 34 members of the Commission are elected by the General Assembly from among persons nominated by member States who possess recognized competence and qualifications in both doctrinal and practical aspects of international law. The membership of the Commission often reflects a broad spectrum of expertise and practical experience within the field of international law, including international dispute settlement procedures. 

 

The mandate of the Commission is the progressive development and codification of international law. The Commission usually spends many years studying areas of international law before presenting draft articles to the UN General Assembly for adoption as a draft convention. Rapporteurs are assigned to be responsible for drafting articles in a particular area, and they undertake extensive studies of the practice of states to determine whether there is a consistent and uniform practice among States. The rapporteurs issue reports to the Commission. In addition, each draft article that is approved by the Commission has an official commentary explaining its object and purpose and providing essential background.  When the ILC Draft Articles are approved, they are approved together with the official commentaries.

 

Sometimes the official commentary to an ILC draft article or the rapporteurs report will indicate whether that draft article is intended to codify a rule of customary international law or is intended to progressively develop the law on that point. Such information can be strong evidence before a court or tribunal if you are attempting to prove or disprove the existence of a rule of customary international law. ILC draft articles are prepared and circulated to all members of the UN for comment. 

 

The official commentaries to ILC draft articles and the reports of the commission and its rapporteurs can be considered for two purposes. First, they can be referred to as part of the travaux préparatoires when interpreting a provision in a convention. Second, they can be referred to as the writings of highly qualified publicists under Article 38(1)(d) as subsidiary means for determining rules of customary international law. Given that the Commission’s articles and official commentaries are approved by a team of 34 international law experts from a wide variety of States, it could be argued that the official commentaries are more valuable as evidence of the existence of a rule of customary international law than the work of one or two individual writers.

 

F.        Jurisdiction of States

1.         Principles of Jurisdiction

The jurisdiction refers to the power of a State to prescribe and enforce laws through its legal institutions. The justification for a State extending its criminal and regulatory laws to particular activities is based on several principles. Almost all States claim jurisdiction based on the territorial principle, under which a State has jurisdiction over activities within its territory. Some states also claim jurisdiction over activities outside its territory which affect its territory.

 

It is accepted that States can also claim jurisdiction based upon the nationality principle, under which a State may also extend its jurisdiction over its nationals when they are outside its territory. Most European States whose legal systems are based on the civil law extend their criminal law to cover their nationals while abroad. States whose legal systems are based upon the English common law usually extend their criminal laws to the actions of their nationals while abroad only in exceptional cases. 

 

Almost all States claim jurisdiction under the protective principle, under which a State asserts jurisdiction over acts committed outside their territory that are prejudicial to its security, such as treason, espionage, and certain economic and immigration offences. It is accepted that there is a narrow category of crimes over which States may assert jurisdiction based upon the universality principle, under which all States have jurisdiction over offenders, no matter their nationality and no matter where the offence was committed. There is universal jurisdiction over crimes such as genocide and war crimes, giving any State the right to assume jurisdiction.

 

The most controversial basis for jurisdiction is the passive personality principle, which establishes jurisdiction based on the nationality of the victim. Very few States attempt to extend the reach of their criminal laws to situations where there only link to the crime is that their national was the victim.

 

Modern counter-terrorism treaties establish jurisdiction among State Parties based on the presence of the offender within their territory. If a person who is alleged to have committed the offence established in the treaty (e.g. hijacking of an aircraft) is present in their territory, a State Party to the treaty is under an obligation to take the persons into custody, and to either prosecute them or extradite them to another State Party that has jurisdiction over the offence.

 

If two or more States have jurisdiction over a particular offence, they are said to have concurrent jurisdiction. In such cases the State which is most likely to prosecute the offender is the State which has custody over him.

 

One of the fundamental principles of international law is that no State may exercise jurisdiction in a place under the territorial sovereignty of another State. The police of one State cannot enter the territory of another State to arrest a person who has committed a crime in their State. Also, if a crime takes place in the territorial sea of a coastal State, no State other than the coastal State my intercept and arrest the ship carrying the offenders. 

 

States enter into bilateral treaties to provide for the extradition of alleged offenders from one State to another. The sending of an alleged criminal to another State for investigation or prosecution in the absence of an extradition treaty is referred to as rendition. This word was made famous by the practice of the Bush administration in sending alleged terrorists to third States for interrogation and/or torture.

 

2.         Immunities from Jurisdiction

The principle of sovereign equality of States requires that the official representatives of one State should not be subject to the laws of another State. Therefore, the law of the sea provides that warships on the high seas are subject only to the jurisdiction of the flag State. Further, warships may never by intercepted and boarded by another State, even if they commit acts contrary to the right of innocent passage and the laws and regulations of the coastal State.  However, if a warship violates the right of innocent passage, it may be escorted out of the territorial sea by warships of the coastal State.

 

The principle of State immunity or sovereign immunity provides that foreign sovereigns enjoy immunity from the jurisdiction of other States. The principle of diplomatic immunity provides that the diplomatic agents of the sending State have complete immunity from the criminal jurisdiction of the receiving State. The immunity of the diplomatic agent is not personal to the diplomatic, but belongs to the State. Therefore, the immunity of a diplomat can be waived by the sending State. Also, the receiving State has the right to expel any diplomatic agent from its country by declaring them persona non grata.

 

Diplomatic relations law also provides that the premises of an embassy or diplomatic mission as well as its records and archives are inviolable. The authorities of the receiving State cannot enter a foreign embassy without the express permission of the head of mission, even in the case of an emergency.

 

G.      Status of the Seas, Outer Space and Antarctica

That part of planet earth that consists of land territory, including islands, is under the sovereignty of States. Their sovereignty extends to the airspace above their land territory. It also extends to a belt of sea adjacent to their coasts, called the territorial sea, subject to the right of the ships of all States to exercise the right of innocent passage through the territorial sea and the right of ships and aircraft of all States to exercise the right of transit passage through and over straits used for international navigation.

 

1.         High Seas

The high seas are governed by several fundamental principles. First, no State may purport to assert sovereignty over any part of the high seas. Second, all States have the right to exercise the freedoms of the seas, including freedoms of navigation, freedom of over flight, freedom to lay submarine cables and pipelines, and freedom to conduct marine scientific research. Freedom of fishing was a traditional high seas freedom but fishing on the high seas is subject to restrictions as set out in the 1982 United Nations Convention on the Law of the Sea. It is generally agreed that freedom of the seas also includes the right of all States to use the high seas for military purposes, including weapons testing and naval exercises.

 

Since no State can claim sovereignty over the high seas, the territorial principle of jurisdiction is not applicable. The general principle governing ships on the high seas is that they are subject to the exclusive jurisdiction of the flag State. There are limited exceptions to this principle, the most important of which applies to piracy. All States have the right to intercept a pirate ship on the high seas and to seize the ship and arrest the pirates. There are treaties creating other exceptions for intercepting ships on the high seas if they are engaged in illegal activities such as slave trading or drug trafficking.

 

2.         Exclusive economic zone

Coastal States are permitted to claim an exclusive economic zone (EEZ) of up to 200 nautical miles from the baselines from which the territorial sea is measured. The EEZ is neither under the sovereignty of the coastal State or part of the high seas. It is a specific legal regime, in which Coastal States have the rights and jurisdiction set out in UNCLOS (United Nation Convention on the Law of the Sea), and other States have the rights and freedoms set out in UNCLOS.

 

Coastal States have the sovereign right to explore and exploit the natural resources of the sea and of the seabed and subsoil in their EEZ. In other words, they have the exclusive right to the fisheries and other living resources of the sea and to the oil and gas resources of the seabed and subsoil. They also have such jurisdiction as is necessary for them to exercise their sovereign rights, included limited jurisdiction over marine scientific research and protection and preservation of the marine environment.

 

Other States have the right to exercise high seas freedoms in the EEZ of any State. With respect to jurisdiction over matters outside of economic activities, the principles of jurisdiction governing the high seas apply in the EEZ. In other words, outside of economic activities, ships in the EEZ are subject to the principle that ships are subject to the exclusive jurisdiction of the flag State.

 

3.         Deep Seabed beyond the limits of national jurisdiction

Under the law of sea, Coastal States have a right to claim an EEZ of out to 200 nautical miles from the baselines from which there territorial sea is measured. Coastal States also have sovereign rights to explore and exploit the natural resource of the seabed and subsoil on their continental shelf. States with a broad continental shelf off their coasts may claim sovereign rights to the resources of their continental shelf out to the outer edge of the continental margin, to a maximum of 350 nautical miles from the baselines. 

 

The natural resources of the deep seabed beyond the limits of national jurisdiction are governed by the principle of common heritage of mankind. No State may claim or exercise sovereignty or sovereign rights over any part of this area or its resources. All rights in the resources in the area are vested in mankind as a whole. An International Sea Bed Authority (ISBA) has been established and it acts on behalf of mankind as a whole to regulate the exploration and exploitation of the natural resources of the deep seabed. No State or natural or juridical person may appropriate any part of the area or its resources except under the authority of the ISBA, which is based in Jamaica. 

 

4.         Outer Space

The law of outer space became an issue only after the USSR launched a satellite into orbit around the earth in 1958 and began the “space race” between the two cold war super powers, the USA and the USSR. The two super powers also worked together with the international community to establish legal principles governing the use of outer space. The principles governing the use of outer space are similar to those that govern the high seas. First, no State may purport to assert sovereignty over any part of outer space. Second, all States have the freedom to use outer space for peaceful purposes. Third, States on whose registry a space object is launched shall retain jurisdiction and control over the space object and over any persons on board the space object.

 

The 1979 Moon Treaty purports to declare the natural resources of the moon and other celestial bodies the common heritage of mankind. However, it has been opposed by the United States and several other important space powers. Therefore, the principle that the natural resources of the moon and other celestial bodies are the common heritage of mankind has not become a principle of customary international law binding on all States.

 

5.         Antarctica

Official claims to sectors of the ice-covered continent of Antarctica were made by seven States – Argentina, Australia, Chile, France, New Zealand, Norway and the United Kingdom.  A sector was also claimed by Admiral Byrd on behalf of the United States, but the United States never officially adopted Byrd’s claim, and refused to recognize the claims of the six claimant States. In 1959 the seven claimant States, together with 5 other States whose scientists had been conducting research in Antarctica (Belgium, Japan, South Africa, the United States and the USSR) entered into the Antarctic Treaty. The Antarctic Treaty “froze” the claims of the seven claimant States, and stated that no new claims to sovereignty would be made. It also stated that Antarctica should be used only for peaceful purposes. The Antarctic Treaty permits States parties to conduct scientific research in Antarctica.

 

H.       Principles Governing Relations between States

The general principles governing friendly relations between States are set out in UN General Assembly Resolution 2625, which was adopted without vote in 1970. It states the progressive development and codification of the principles below would secure their more effective application within the international community and would promote the realization of the purposes of the United Nations.

 

UN Resolution 2625 elaborates on the following seven principles:

(a)   The principle that States shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any State, or in any other manner inconsistent with the purpose of the United Nations

(b)   The principle that States shall settle their international disputes by peaceful means in such a manner that international peace and security and justice are not endangered

(c)   The duty not to intervene in matters within the domestic jurisdiction of any State, in accordance with the UN Charter

(d)   The duty of States to co-operate with one another in accordance with the UN Charter

(e)   The principle of equal rights and self-determination of peoples

(f)    The principle of sovereign equality of States

(g)   The principle that States shall fulfill in good faith the obligations assumed by them in accordance with the UN Charter

 

I.          Responsibility of States for Wrongful Acts

The area of international law referred to as “State responsibility” refers to the principles and rules for determining when a State is responsible for breaching the international obligations it owes to another State and the consequences of the breach. The general principle is that a State is internationally responsible to other another State for its internationally wrongful acts.

 

A State commits internationally wrongful act when conduct consisting of an act or omission;

            (a) is attributable to the State under international law; and

(b) constitutes a breach of an international obligation of the State.

 

Therefore, if a dispute arises between two States, the first question that is usually asked is whether the State whose conduct is in question owed an international obligation to the other State under either a treaty or under customary international law. The second question is whether that obligation was breached by conduct consisting of either an act or an omission that is attributable to the State.

 

The rules on attribution are based on common sense. The conduct of an organ of the State is attributable to the State. In its relations with other States, a State acts through its official representatives, such as its Head of State, Prime Minister or President, Minister of Foreign Affairs, Ambassadors, as well as through government ministries and departments. The official acts of these persons and organs are attributable to the State.

 

The conduct of private persons or private entities is generally not attributable to the State.  However, the conduct of a person or entity empowered by the law of the State to exercise elements of government authority is also attributable to the State. A State is in breach of an international obligation when conduct attributable to it is not in conformity with what is required by the obligation. A State may not rely on provisions of its internal or domestic law as justification for failure to comply with an international obligation.

 

The State responsible for the internationally wrongful act is under an obligation to cease the wrongful act if it is continuing. It is also under an obligation to offer appropriate assurance and guarantees of non-repetition, if circumstances so require. In addition, the State responsible for the internationally wrongful act is under an obligation to make full reparation for the injury caused to the other State by the internationally wrongful act. Injury includes any damage, whether material or moral, caused by the internationally wrongful act.  

 

The forms of reparation under international law are restitution, compensation and satisfaction. The preferred form of reparation is restitution, which requires the State to re-establish the situation which existed before the wrongful was committed.  Insofar as the damage is not made good by restitution, the State much pay compensation to cover the financially assessable damage, including loss of profits insofar as it is established. If the injury cannot be made good by either restitution or compensation, the State must provide satisfaction, which may consist of acknowledgement of the breach, an expression of regret, a formal apology or another appropriate remedy.

 

The principles of state responsibility provide that a State which preclude the wrongfulness of an act.  They include:

a) Valid consent by the injured State to the commission of the act

b) Self-defense under Article 51 of the UN Charter

c) Force majeure

d) Distress

e) Necessity

f) Valid counter-measure in respect of a previous wrongful act

 

A counter measure is a form of self-help that is taken in order to induce a State which is responsible for an internationally wrongful act to comply with its obligations. A counter measure consists of the non-performance for the time being of international obligations owing to the responsible State. An example of a countermeasure would be the United States freezing all assets of Iran in US banks in response to the takeover of the US Embassy in Iran in 1979.

 

There are several restrictions on the use of counter measures. They cannot involve the use of force or be in violation of obligations for the protection of fundamental human rights. Also, counter measures are limited by the principle of proportionality, and must be commensurate with the injury suffered, taking into account the gravity of the internationally wrongful act, and the rights in question.  

 

J.         Settlement of Disputes

States have an obligation to settle their disputes by peaceful means. However, States are generally not under any legal obligation to settle their disputes by resorting to an international court or tribunal. A dispute cannot be referred to an international court or arbitral tribunal with the express consent of the States concerned.

 

The ICJ is the chief judicial organ of the United Nations and all members of the UN are automatically parties to the Statute of the ICJ. The jurisdiction of the ICJ in “contentious disputes” between States is subject to the principle of consent. It can obtain jurisdiction in three ways:

 

(a) The States parties to a dispute may enter into an ad hoc agreement to refer a particular legal dispute to the court.

(b)  States can submit an “optional clause declaration” to the UN Secretary-General declaring that they accept the jurisdiction of the ICJ over certain categories of disputes with other States which have also filed an optional clause declaration. This category of disputes is quite rare, as many States are not willing to accept the jurisdiction of the ICJ in advance for wide categories of disputes.

(c) Many international conventions contain dispute settlement clauses called “compromissory clauses” allowing disputes between States parties to the convention to refer disputes concerning the interpretation or application of provisions of that convention to the ICJ by one of the parties to the dispute. Some conventions allow States to “opt out’ of such compromissory clauses.

 

If a dispute between two States is decided by the ICJ, the decision of the court is final and binding as between the parties to the case.  It is not binding on other States. However, to the extent that the ICJ pronounces on issues of customary law or treaty law, its judgment will be treated as an authoritative interpretation of international law by many States. The ICJ also has advisory jurisdiction. The UN Security Council and the UN General Assembly may request advisory opinions on any legal question. The UN General Assembly may also authorize other UN organs or specialized agencies to request advisory opinions on legal questions arising within the scope of their activities.
