The Concept of Law - Hart's, And — 7-topic bundle

Hart begins Chapter 5 by imagining a hypothetical society that only has primary rules of obligation. These are rules that tell people what they must or mustn't do, like "don't steal" or "keep promises." While such a society might function for a while, especially if it's small and close-knit, Hart argues that it would suffer from three major defects. These defects highlight why secondary rules are essential for a sophisticated legal system.

In Chapter 5, Hart introduces the concept of secondary rules as a solution to the defects of a legal system based only on primary rules of obligation. Primary rules tell you what you must or must not do (e.g., "don't steal"). Without secondary rules, a society would face issues like uncertainty about what the rules are, static rules that can't adapt, and inefficient ways of enforcing them.

Secondary rules address these defects. Rules of change are designed specifically to tackle the problem of a legal system's static character. They provide the means for a society to evolve its primary rules.
