When we say a law is normative, we mean two things. On the one hand, it means the particular law was made according to the procedure laid down for its making. This is technical validity or normativity of the law, falling within the pure theory of law by Hans Kelsen. On the other hand, a law is normative if it has some moral content in it.
The normativity of law is often equated with, or at least connected to, citizens' moral obligation to obey the law. For a long time, it was thought that whether citizens had this moral obligation to obey was simply the flip side of the question of whether the government was legitimate.
