Rule according to law; rule under law; or rule according to a higher law.
The rule of law is an ambiguous term that can mean different things in different contexts. In one context the term means rule according to law. No individual can be ordered by the government to pay civil damages or suffer criminal punishment except in strict accordance with well-established and clearly defined laws and procedures. In a second context the term means rule under law. No branch of government is above the law, and no public official may act arbitrarily or unilaterally outside the law. In a third context the term means rule according to a higher law. No written law may be enforced by the government unless it conforms with certain unwritten, universal principles of fairness, morality, and justice that transcend human legal systems
