How Public International Law Differs From Private International Law

Knowing the difference between public and private international law is important for everyone who works in the international legal world. The subject deals with rules for states and international organizations, centering on treaties, human rights, seafaring laws and settling conflicts. It defines how countries should communicate, cooperate and deal with arguments in the world arena. Such examples are the United Nations Charter and the Geneva Conventions.

Unlike public international law, private international law concentrates on problems that arise over the actions of private people, businesses or organizations from different countries. It lays out which national laws are to be used in situations when an international contract, family legal issue or an inheritance issue arises. Private international law is able to solve disputes concerning multiple legal systems by guaranteeing fairness and certainty. Even though public international law regulates what states do and issues that concern all nations, private international law manages activities between people and companies across borders. Knowing these differences plays an important role in dealing with law and diplomacy around the world.

Understanding the Basics

Before anything else, it is necessary to understand what public international law and private international law involve and the areas where each functions. Private international law is there to decide where lawful issues between individuals or businesses from different countries can be addressed and how those cases should be handled. Even though both adopt different practices in the face of organizational difficulties, the core matters, outcome goals and main laws used are different due to their unique developments.

What Is Public International Law?

What Is Private International Law?

• Private international law is discussed and how it helps settle disputes between individuals and companies that operate internationally.
• Private international law or conflict of laws is how national systems sort out legal disputes that have some connection to a foreign nation.

• Private international law mainly aims to answer who the resolving authority should be, which court shall hear the dispute and if a judgment reached in a certain nation can be acknowledged and carried out by another country.

Key Legal Sources for Each Type

• Looking to treaties, conventions, case law and national laws when working with both public and private international law.

Common Mistakes to Avoid When Differentiating

It is important to correctly tell public international law apart from private international law when dealing with law matters between countries. A common mistake is confusing where cases should be heard which results in inaccurate classifications. Still, failure to remember that applying specific laws from one area to another such as using public law rules in private disputes or vice versa, can cause confusion.

Confusing Jurisdictional Boundaries

• Take care not to place legal problems in the wrong legal category because of misunderstanding the laws.
• At times, people overlook the difference between public and private fields in international law. If the individuals or businesses involved in a case are mistaken for nations, organizations or the opposite, the law may not be applied correctly.

Law relating to state independence, breaking a treaty and matters of human rights are usually part of public international law, but issues with cross-border business deals or personal lawsuits mostly come under private international law.

Misinterpreting Legal Instruments

• Most of these errors develop when applying one system of laws in the wrong domain by mistake. Looking at it from another angle, if a person tried to sort out a private company’s dispute using a treaty specifically developed for states, it would be a serious error.
• In addition, making a national conflict-of-laws rule the sole method for dealing with a state-based violation of international law is not proper. You must understand the background and aim of each law within a field to properly interpret it.

Overlooking Cultural and Legal Norms

Certain cross-border legal matters, disagreements and uses of international laws can be too difficult for regular lawyers to handle without the needed experience.
• The accurate advice you receive from experienced international law counsel is particularly suited to your legal situation based on the specific rules and international aspects involved. International lawyers have the skills needed to create solid plans, prevent costly errors and improve your possibilities of a successful outcome in international legal cases.

Ignoring Enforcement Challenges

• What might happen if the issue of enforceability is neglected in global disputes.
• International legal disputes may suffer from ignoring the problems associated with carrying out international law or ensuring everyone complies. How enforcement is carried out is not the same for public and private international law. This problem is especially noticeable when no worldwide enforcement body exists for public law.
• While it is possible for countries to recognize and enforce each other’s judgments in private international law, the rules for doing so change from one country to another.
