Which concept emphasizes that laws must be administered impartially?

The concept that emphasizes that laws must be administered impartially is embodied in the principle of due process. This principle ensures that all individuals are treated fairly under the law and that legal proceedings are conducted according to established rules that guarantee fairness and transparency.

Due process is fundamental to the legal system as it protects individuals from arbitrary decisions by the government and ensures that everyone has the right to defend themselves and be heard. It applies to various stages of the legal process, including arrest, trial, and sentencing, ensuring that legal rights are respected and upheld.

While the other concepts, such as publicity, consent, and justice, relate to legal and ethical principles, they do not specifically capture the essence of impartial administration of laws in the same clear manner as due process does. Publicity refers to the requirement that laws be made known to the public, consent involves the agreement of parties, and justice is a broader concept that encompasses fairness but does not exclusively focus on impartiality in legal proceedings. Thus, due process stands out as the correct choice for emphasizing the fair and impartial administration of laws.
