National law is a term for the legal system of a country. It is usually practiced by the courts and the legal profession. It may also be referred to as domestic law. It may be the result of a national constitution or a treaty, and it is applied within the jurisdiction of the state.

Some scholars believe that only states can enter into international law commitments voluntarily. Nevertheless, there is a growing trend that judges domestic actions in light of international law. This can be accomplished through a process known as judicatory and diplomacy.

One important example of this is the European Union. A unified, supranational legal framework is the most prominent. However, there are other examples, such as the United Nations Security Council.

In some jurisdictions, national laws can become international law if the relevant rules are adopted as part of a treaty. This can occur, for instance, if the Geneva Conventions require the country’s laws to conform to the provisions of the treaties.

Similarly, a nation’s laws may not apply when there is conflict between the nation’s system and a supranational legal system. For instance, if the nation’s court rejects a rule that is in conflict with a supranational tribunal, it can be considered invalid.

In general, the courts will accept a rule if it is consistent with the enacted statutes, the rules of a national court, or a judicial body. But this does not mean that all states recognize that the courts or judges themselves make the laws.
