Equality before the law, known as equality under the law, equality in the eyes of the law, legal equality, or legal egalitarianism, is the principle that all people must be equally protected by the law. The principle requires a systematic rule of law that observes due process to provide equal justice, and requires equal protection ensuring that no individual nor group of individuals be privileged over others by the law. Also called the principle of isonomy, it arises from various philosophical questions concerning equality, fairness and justice. Equality before the law is one of the basic principles of some definitions of liberalism. The principle of equality before the law is incompatible with and does not exist within systems incorporating legal slavery, servitude, colonialism, or monarchy.
Article 7 of the Universal Declaration of Human Rights (UDHR) states: "All are equal before the law and are entitled without any discrimination to equal protection of the law". Thus, it states that everyone must be treated equally under the law regardless of race, gender, color, ethnicity, religion, disability, or other characteristics, without privilege, discrimination or bias. The general guarantee of equality is provided by most of the world's national constitutions, but specific implementations of this guarantee vary. For example, while many constitutions guarantee equality regardless of race, only a few mention the right to equality regardless of nationality.
