Generally, when we talk about a-national law, we mean a legal system that combines the elements of national law and international law. A-national law has been in the spotlight in recent years. Some argue that the concept is just wishful thinking, while others argue that a-national law is the real thing.
Various scholars have proposed different definitions of a-national law. Some claim that a-national law is simply the application of international law within a national legal system. Others claim that it is a form of legal harmonization, in which differences between domestic laws are eliminated.
Although a-national law has been a subject of controversy for many years, there is no real consensus on whether it is actually a viable alternative to national law. A-national law may be a legitimate alternative to domestic law, but it may also jeopardize the separation of national and international law. Some believe that a-national law only applies to commercial transactions that do not involve geography.
One of the oldest and arguably most influential legal systems was that of the natural law school. Natural law was a form of international law that gained widespread acceptance during the 18th century. It was grounded in the belief that the rights of individuals were governed by universal principles and not by particular nations. This notion remained relevant in the 18th and 19th centuries.
The concept of natural law was a precursor to modern international law. It is still prevalent in international politics and governmental practices.
