Law & legal science were constituted as an arranged system and social order over a long time, following many millennia of historical development. Law has a great importance, because it became a pattern of human behaviour and an irreplaceable regulator of regulations and processes of social life of men. If there was no law or legal order the world would be lost in chaos and certainly there would be no organized society. Legal situation in most countries of the world, and especially in the countries of the Balkans, and in BiH in particular, is disorderly, inefficient and dysfunctional, and hence does not provide legal security to citizens or institutions. Numerous negative tendencies have arisen, the most important of them being: simultaneous existence and application of a number of legal systems in the country, penetration of the Anglo-Saxon law in Euro-continental legal system, etatism in law and legal regulations, politicization of legal system, excessive norming, proliferation of law and regulations, absolutization and individualization. Therefore it is time that further erosion and simplification of law be brought to an end.
