Legal validity, established by a rule of recognition in each legal system is dependant upon criteria. Legal positivism is here sometimes associated with the homonymic but independent doctrines of logical positivism (the meaning of a sentence is its mode of verification) or sociological positivism (social phenomena can be studied only through the methods of natural science).

The concept of a legal rule, that is, does not include all correctly reasoned elaborations or determinations of that rule. There are many necessary connections, trivial and non-trivial, between law and morality.
The Hart/Dworkin debate begins with Dworkin's 1967 paper The Model of Rules, where Dworkin rejects to Hart four doctrines: that law consists of rules; that legal rules are identified via a rule of recognition, by tests with their pedigree not content; that where a rule. (It is a curious fact about anti-positivist theories that, while they all insist on the moral nature of law, without exception they take its moral nature to be something good. By using cases such as Riggs v Palmer23 Dworkin demonstrates that certain situations necessitate the application of principles in order to avoid absurd results. Law stands continuously exposed to demands for justification, and that too shapes its nature and role in our lives and culture. The imperativalist acknowledges that ultimate legislative power may be self-limiting, or limited externally by what public opinion will tolerate, and also that legal systems contain provisions that are not imperatives (for video essay university of cincinatti example, permissions, definitions, and so on). Where there is law there is also morality, and they regulate the same matters by analogous techniques. Discretion, however, may be a potentially misleading term here. For a related argument see Shapiro.
