What Is International Law: Its Branches And Career Scope

International law comprises rules and standards that guide how countries and other international groups, like organisations, interact. Unlike domestic laws, which vary from country to country, international law operates across borders, helping nations collaborate and maintain peace. English philosopher Jeremy Bentham introduced the concept of international law, which has grown increasingly important in our globalised world. It plays a crucial role in resolving disputes, protecting human rights, and ensuring global security. Understanding international law is essential for navigating the complexities of international relations and addressing the challenges of our interconnected world. 

This article will help us understand what is international law is, private and public international law, and the principles of international humanitarian law. Additionally, we will look at the best universities for studying international law, the requirements for the international law bar exam, and the job opportunities available in South Africa.

What Is International Law: Definition

International law is a set of rules that countries and international organisations follow when interacting. These rules cover many areas that involve cooperation between nations, like international business, human rights, protecting the environment, and solving disputes. It also includes economic partnerships, humanitarian aid, and global environmental challenges. 

International law is essential for maintaining order and promoting cooperation in our interconnected world. Whether a company navigates trade regulations across borders or an organisation provides aid in disaster areas, international law helps ensure that these actions are done fairly and legally.

Key Principles and Concepts Of International Law

International law is guided by several fundamental principles that help shape how countries interact and work together. These principles ensure that international relations are based on peace, stability, and cooperation. Here are the main principles of international law:

• Sovereignty: Every country has the right to govern itself without interference from other nations. 
• Peaceful Resolution of Disputes: Countries should solve conflicts through negotiation, mediation, or legal processes rather than force. 
• Jus Gentium (Law of Nations): This refers to the basic legal rules that guide how countries interact with one another.
• Jus Inter Gentes (Law Between Nations): This focuses on the legal relationships and agreements between countries, showing that international law depends on the cooperation and agreements of the global community.
• Mutual Consent and Cooperation: International law is based on the agreements and mutual understanding between countries. It is not imposed but instead agreed upon by the nations involved.
• Global Order and Stability: International law aims to create a stable and fair world where countries can live together peacefully and work together to address global issues.

Types Of International Law

International law is a fundamental framework guiding how countries associate with one another, setting the rules and norms governing a wide range of cross-border issues. Some main branches of international law include Private International Law, Public International Law, and International Humanitarian Law, each addressing different aspects of global interactions. Let’s learn about these types in detail.

Private International Law

Private International Law, sometimes known as conflict of laws, deals with legal disputes that involve individuals or businesses from different countries. This branch of law determines which country’s legal system and courts have jurisdiction over cases that include foreign elements. For instance, if an American and a French citizen marry in France but later seek a divorce in Canada, Private International Law will decide which country’s legal framework will apply.

Private International Law plays a crucial role as the world becomes increasingly interconnected. With businesses operating across borders and people living more globalised lives, legal issues often span multiple jurisdictions. This branch of law ensures that these cross-border disputes are handled fairly, respecting the legal systems of all involved countries and promoting consistency in international dealings.

Public International Law

Public International Law governs the relationships between different countries and international organisations. It sets the rules for various global issues, including environmental protection, human rights, and international trade. Public International Law is found in treaties, conventions, and customs that countries agree to follow.

Public International Law is essential in addressing global issues affecting the international community, such as climate change, international peace, and human rights protection. For instance, international agreements like the Kyoto Protocol on climate change and the Convention on the Rights of the Child are examples of this law in action. Additionally, Institutions like the International Criminal Court (ICC) also play a significant role by prosecuting individuals responsible for serious international crimes, including genocide and crimes against humanity.

International Humanitarian Law

International Humanitarian Law (IHL), also known as the law of armed conflict or the law of war, consists of rules designed to limit the effects of armed conflict. It aims to protect those not involved in the fighting, such as civilians and medical workers, and to restrict the methods and means of warfare.

International Humanitarian Law is critical for maintaining humanity during times of war. It protects people who are not participating in the conflict, such as civilians and healthcare workers, and ensures they are treated with dignity and respect. The Geneva Conventions, a crucial part of IHL, have been universally adopted and outline the obligations of parties in conflict to treat captured soldiers and civilians humanely and to respect neutral sites such as hospitals and schools.

International Humanitarian Law: Key Principles 

International Humanitarian Law is based on several key principles that guide conduct during armed conflicts. These principles help maintain international order and protect human rights during conflicts. They are enforced by various organisations, including the International Criminal Court, which prosecutes individuals for serious violations of International Humanitarian Law, such as war crimes, ensuring that justice is served. Let’s take a look at some of them listed below:

• Distinction: Parties to a conflict must always distinguish between soldiers and civilians, ensuring that attacks are directed solely at legitimate military targets.
• Proportionality: Military operations should balance the military advantage gained and the potential harm to civilians, avoiding unnecessary or excessive force.
• Precaution: Warring parties must take all feasible precautions to minimise harm to civilians and civilian objects, including providing warnings before attacks when possible.
