The concepts of “due process of law” and “natural justice” are often linked in legal discussions, though they emphasize slightly different aspects of fairness. Both are integral to ensuring justice but focus on distinct legal protections. Due process of law is a fundamental legal principle that guarantees individuals the right to fair treatment by the legal system. It ensures that no one can be deprived of life, liberty, or property without proper legal procedures. This includes the right to be informed of any allegations and the opportunity to defend oneself in a fair and unbiased setting. Due process is a cornerstone of legal systems worldwide, often enshrined in constitutions to safeguard individual rights. Natural justice, on the other hand, specifically governs the fairness of administrative and judicial proceedings. It revolves around two key principles: the rule against bias and the right to a fair hearing.

• The rule against bias requires decision-makers to be impartial, free from personal or financial interest in the case. This principle prevents even the appearance of unfairness, ensuring decisions are objective.
• The right to a fair hearing grants individuals the opportunity to present their case fully. It includes the right to know the charges, call and cross-examine witnesses, submit evidence, and have legal representation. This ensures decisions are made after a thorough review of the facts and arguments.

In essence, due process of law provides a comprehensive legal framework that includes natural justice as a critical component. While due process focuses on broader legal protections, natural justice zeroes in on ensuring fairness and impartiality in specific proceedings. Together, they are vital to upholding justice and protecting individual rights within legal systems worldwide. The correct answer is: The principle of natural justice.
