DUTY IMPOSING AUSTINIAN rules regulating behavior, while secondary rules regulate other rules, i.e. the primary rules-Stepping back in time, beginning with primary rules, they involve a “minimum content” of behavior necessary for the survival of a primitive society e.g., no killing no stealing. Each member lives to their own individual creed or morals. Violators may be dealt with, vigilante style. However, for its continued survival the REQUIREMENTS ARE STRINGENT. It must be a small society sharing common interests, the rules must be accepted by the majority and, they must live in a stable environment. If any of these variables change, certain defects of being static, inefficient and uncertain may be exposed. According to Hart, the most basic remedy for such a society is to write down these primary rules, which then becomes a rudimentary rule of recognition.
