Legal Principles, Legal Values and Legal Norms: are they the same or different?

Legal principles, legal values, and legal norms are essentially part of the same notion. Often in legal literature, legal principles are considered to be legal norms, general legal norms, legal values etc. In fact, legal principles are just legal norms that different from the latter are legal norms of general application that ignore specific legal facts. They can be considered as basic norms that represent the general consensus on basic society understandings. As such they are also kinds of default rules of behavior. From this perspective, the legal principles are rules of human behavior that used to be considered as just, before the law started being written. Thus, legal values would be considered a more general legal norms vis-à-vis legal principles and legal norms. Nonetheless, the coexistence of these three notions shows the complexity of their correlation and gives us an initial idea on what we will go through in out attempt to perform of comparative analysis between them.
