What is international law and its sources

In many ways, international law is analogous to a massive puzzle that must be assembled in order to create a cohesive world order. To ensure peace and stability, legal systems from all over the world interact with one another, and regulations are formed and updated.

Although international law is complex, it can be broken down into its fundamental components in order to better understand it. We will look at four of the most important sources of international law in this blog post. You might find this material useful as you continue your research on the issue.

The Sources of International Law

The corpus of legislation that controls the relationships between different governments is referred to as the law of nations. It originates from older sources such as custom, treaty, and precedence. A number of different international legal instruments, such as the Universal Declaration of Human Rights, the Geneva Conventions, and the rules of war, are together referred to as the canons of international law.

Customary International Law

The collection of laws and principles that determine how nations should relate to one another is known as international law. It seeks to ensure that disagreements on a global scale are handled by peaceful means and is predicated on the idea that all states are equal in terms of their sovereign authority.

The Sources of International Law: Customary Law

Customary international law is a set of laws that have developed over time as nations engaged with one another. Treaties, customary practises, and basic humanitarian norms are common places to find these rules.

Customary international law is based on the idea of sovereign equality of states, which asserts that all nations have the same authority to create binding agreements. The United Nations General Assembly endorsed this principle in resolutions A/RES/3266 (XXII), 3281 (XXIII), and 3362. (XXIV).

Customary international law can be traced back to ancient times, when warring societies formed alliances and signed treaties with one another. These accords were eventually put into written form and regulated by courts or other authoritative institutions.

These institutions evolved into what we now call international organisations like the United Nations. The UN system serves as an arbiter in conflicts between member nations, promotes human rights, and offers emergency help. In addition to the UN system, regional groups such as the European Union and NAFTA apply customary international law.

Supranational Institutions and International Law

The interactions between sovereign nations are governed by international law. The concept is based on the idea that independent states must manage their own domestic and foreign affairs while also respecting the rights of other sovereign nations. Similarly, international law acknowledges the existence of a global community bound together by common principles.

Treaties, Customary International Law, judicial decisions, and academic papers all contribute to the development of international law. One of the cornerstones of international law is the Vienna Convention on Diplomatic Relations.

International Law’s Conclusion 

International law is the body of law that governs state-to-state relationships. It has two origins: custom and treaties. Based on human behaviour, custom develops a basic legal norm that may subsequently be applied to individual instances. Treaties, on the other hand, are written agreements made between states. They develop particular rules or principles that govern how governments will act in specific situations, and they frequently contain mechanisms for enforcement.
