Under conditions of applicability, the rules of legal systems can be branded as invalid or valid. On the other hand, the ?unfair? qualifying for standards, the legal and political systems has become an element of external rating, then, given the potential ambiguity of the term ?justice?, its use was avoided to not fall into subjectivism due the principles of legality and legal certainty. However, the history of legal systems, attached to a political and legal culture, has demonstrated the existence of legal regulations on unfair end. With an analytical, synthetic, and pragmatic methodology, from the kind of research that warrants the Philosophy of Law, the extremely unfair law formula will be discussed and the way to generalize it will be examined from the claim of universality of human rights.
