Which of the following best represents a core principle

Solution

One of the fundamental principles of natural justice is the rule against bias, commonly expressed as "nemo judex in causa sua" — which means no one should be a judge in their own cause. This ensures impartiality in decision-making by administrative or quasi-judicial authorities. Along with the right to be heard (audi alteram partem), it forms the bedrock of fair procedure in administrative law. These principles are applicable even where statutes are silent and help in preventing arbitrary or biased decisions.
