Then, a definition of principles is proposed, aiming to understand what their unique characteristics are when compared to other norms of the legal order.
Thirdly, the conditions for the application of principles and rules are examined, which are the normative applicative postulates. That will surpass both the mere praise of values, which does not create behaviors, and the automatic application of rules. It will be shown, on one hand, that principles not only explicit values, but also set forth precise species of behaviors, though indirectly; on the other hand, the creation of conducts by rules is also to be weighed, even though the behavior set forth in advance may be overcome, depending on the accomplishment of a few requirements.Theory of Legal Principles This book intends to help understand and apply principles and rules better.
