Natural Law System Jus Naturale Law of Nature Natural Law Theory Universal Moral Law The Natural Law System is a legal philosophy asserting that laws are derived from a set of inherent moral principles and universal truths that govern human behavior, existing independently of human-made laws. It posits that these principles are discoverable through reason and are inherent to human nature, providing a basis for evaluating and guiding positive law. Human Rights Charters often draw on principles from the Natural Law System, asserting rights that transcend national legal systems. The abolition of apartheid in South Africa was partly justified by appeals to the universal moral principles of the Natural Law System.
