what’s Hart’s theory of law? what’s Dworkin’s theory of law? are you struggling to understand the theories because yes clearly both relevant (they’re both on law) but maybe or maybe not it makes a difference to judicial decisions. if the answer is no (and i’m not saying it is) then what other theory seems more likely on how judges make law? there are unlimited arguments in jurisprudence so you have to reach your own conclusion. there are no right answers; only good arguments.
