How to determine the effects of legal rules?

Given the number of legal rules, the principles of determining their effects are as follows:

a) Higher rules prevail over lower rules;

b) Later rules prevail over previous rules; and,

c) Special rules prevail over general rules.

In the process of adjudication, laws and regulations have greater effects than rules. According to administrative litigious law, the courts must follow laws and regulations but may take administrative rules and local rules as references.
