International law is the set of rules generally accepted as binding between states. It serves as a framework for stable international relations. The definition has evolved over time to include not just rules between states, but also individuals and international organizations. International law regulates the activities of entities with international personality like states, international organizations, and individuals. It has different components - public international law governs relations between states; private international law addresses jurisdiction in legal conflicts between citizens of different countries; and supranational law comprises collective laws states voluntarily accept.

2. INTRODUCTION TO
INTERNATIONAL LAW
What is international law?
Set of rules generally regarded and accepted as binding in relations between states and
between nations
international law serves as a framework for the practice of stable and organized
international relations.
The definition of ‘nations’ or ‘states’
• political bodies
• societies of men
• who have united together and combined their forces
• in order to procure their mutual welfare and security
Dr. Sheikh Muhammad Adnan

3. NATURE OF INTERNATIONAL LAW
DEFINITION OF INTERNATIONAL LAW:
International law is a collection of rules governing relations between states. It is a
mark of how far international law has evolved that this original definition omits
individuals and international organizations—two of the most dynamic and vital
elements of modern international law. Furthermore, it is no longer accurate to view
international law as simply a collection of rules; rather, it is a rapidly developing
complex of rules and influential—though not directly binding—principles,
practices, and assertions coupled with increasingly sophisticated structures and
processes.
Dr. Sheikh Muhammad Adnan

4. SUBJECTS OF INTERNATIONAL
LAW
• International personality
• criteria of statehood
• recognition – constitutive theory – declaratory theory
• other subjects of international law – international
organization – liberation movement and insurgent group –
individual
Dr. Sheikh Muhammad Adnan

5. WHAT IS MEANT BY THE LAW OF
NATIONS?
• The law of nations is the science of the rights exist between nations and
states, and of the obligations corresponding to these rights.
The meaning of international law
• modern approach: “the body of law that regulates the activities of entities
possessing international personality” • traditional approach: “the conduct
and relationships of states”
Dr. Sheikh Muhammad Adnan

6. INTERNATIONAL LAW
Basically defined, international law is simply the set of rules that countries
follow in dealing with each other. There are three distinct legal processes that
can be identified in international law that include public international law (the
relationship between sovereign states and international entities such as
international criminal court), private international law
• (addressing questions of jurisdiction in conflict), and supranational law (the
set of collective laws that sovereign states voluntarily yield to). But this basic
definition must be supplemented with three more- complex explanations—is
international law really law, the way the laws of the united states, enforced by
courts and police, are? Where do we find the rules of international law? Are
they written down somewhere? Finally, how is international law enforced, if
there is no world government?

“PUBLIC INTERNATIONAL LAW IS BODY OF CUSTOMARY AND
CONVENTIONAL RULES, WHICH ARE CONSIDERED BINDING
ON CIVILIZED STATES IN THERE RELATION WITH OTHERS.”
(OPPENHEIM)
Dr. Sheikh Muhammad Adnan

13. PRIVATE INTERNATIONAL LAW
• Private international law describes the body of law surrounding which law
governs when there is a conflict between citizens of different countries. In
common law jurisdictions, it is sometimes known as "conflict of laws."
• Typically, one will be asking one or more of three questions when
researching a private international law problem:
• In which jurisdiction should the dispute be decided?
• Which law should be applied?
• How should a foreign judgment be enforced?
