Principles of Natural Justice: Meaning, Explained Simply (2026)
The principles of natural justice are basic fairness rules that any court or authority must follow before it decides something against a person. The two core rules are audi alteram partem, which means hear the other side before you act against them, and nemo judex in causa sua, which means no one should be a judge in a cause in which they have an interest. A third rule, that decisions should give reasons, is widely applied in India. This guide explains each principle, where it applies, an Indian example, the constitutional link, and the terms people confuse.

01What natural justice means
Natural justice is not a single statute. It is a set of fairness rules that courts have built up and now treat as part of the rule of law. The idea is simple. Before the State, a court, a tribunal or any authority passes an order that hurts a person, that person should get a fair process. If the process is unfair, the order can be struck down even if the final decision might have been correct.
In India, natural justice is read into Article 14, which guarantees equality and forbids arbitrary State action, and Article 21, which protects life and personal liberty through a fair procedure. The landmark ruling in Maneka Gandhi v Union of India (1978) tied fair procedure firmly to these articles.
Natural justice asks two plain questions. Was the person heard, and was the decision maker neutral. If either answer is no, the order is at risk.
02Audi alteram partem: the right to be heard
Audi alteram partem means hear the other side. No one should be condemned, penalised or have their rights taken away without being told what is alleged and given a fair chance to answer. In practice this usually includes:
- Notice: the person must be told clearly what is alleged against them.
- Opportunity to reply: they must get a real chance to present their side, with documents and, where needed, witnesses.
- Disclosure: material used against them should be shown to them, so they can meet it.
- A fair hearing: the decision should be based on the evidence and the reply, not on something decided in advance.
This is why an order passed behind a person back is open to challenge. In civil courts, an ex parte order passed without hearing a party can be set aside, which is a direct expression of this principle. See Order 9 CPC and ex parte orders and how to restore a dismissed case.
03Nemo judex in causa sua: no bias
Nemo judex in causa sua means no one should be a judge in a cause in which they have an interest. A decision maker must be neutral and must also appear neutral. Bias can take several forms:
- Personal bias: a close relationship or hostility towards a party.
- Pecuniary bias: a financial interest in the outcome, however small.
- Official or subject matter bias: a strong prior involvement with the issue.
The test is not only actual bias but a real likelihood or reasonable apprehension of bias in the mind of a fair observer. Justice must not only be done but be seen to be done. A decision maker who has such an interest should step aside, which is called recusal.
04Reasoned decisions
Indian courts increasingly treat the duty to give reasons as a third limb of natural justice. A reasoned order shows that the authority applied its mind, lets the affected person understand why they lost, and allows a higher court to check the decision in appeal or judicial review.
An order that simply states a conclusion without reasons, especially one that affects rights, can be set aside as unfair. This is why quasi judicial authorities, tribunals and disciplinary bodies are expected to record reasons, not just outcomes.
Fairness, not a fixed form
Natural justice does not demand a court style trial everywhere. What a fair hearing looks like changes with the setting. A disciplinary inquiry, a tax order and a licence cancellation each need a fair process suited to them, not an identical procedure.
05Where it applies and its limits
Natural justice applies widely to State and public authorities, tribunals, disciplinary bodies and any body deciding questions that affect a person rights or livelihood. It applies even where a statute is silent, because courts read fairness into the power.
But it is not absolute. Recognised limits include:
- Urgency: in a genuine emergency, a pre-decision hearing may be delayed, with a hearing given soon after.
- Statutory exclusion: a clear law may limit the hearing, though courts read such limits narrowly.
- Useless formality: where a hearing would make no difference at all, courts sometimes excuse it, but this is applied with great care.
Where natural justice is denied, the usual remedy is to challenge the order, often by a writ petition in the High Court or Supreme Court. See Article 32 vs Article 226.
06A simple example
Suppose an employee is dismissed by a public body for alleged misconduct, but is never told the exact charges and never given a chance to reply or to see the evidence. Even if the body genuinely believed the employee was at fault, the dismissal can be challenged because audi alteram partem was denied.
Now suppose the officer who decided the matter was the very person the employee had earlier complained against. That raises a reasonable apprehension of bias under nemo judex in causa sua. On either ground, a court can set aside the order and send the matter back for a fair process.

09Frequently asked questions
What are the principles of natural justice?
They are basic fairness rules a court or authority must follow before passing an order against a person. The two core rules are audi alteram partem, hear the other side before acting, and nemo judex in causa sua, no one should judge a case in which they have an interest. Giving reasons is often treated as a third rule.
What does audi alteram partem mean?
It means hear the other side. A person must be told what is alleged against them and given a fair chance to reply, with access to the material used against them, before an adverse order is passed. An order made without this can be challenged and set aside.
What does nemo judex in causa sua mean?
It means no one should be a judge in a cause in which they have an interest. The decision maker must be neutral and appear neutral. Personal, financial or subject matter bias, or even a reasonable apprehension of bias, can make the order liable to be set aside.
Is natural justice part of the Constitution?
It is not written as a separate article, but Indian courts read it into Article 14, which forbids arbitrary State action, and Article 21, which protects life and liberty through a fair procedure. The Maneka Gandhi ruling of 1978 tied fair procedure firmly to these articles.
Can natural justice be excluded?
Only in limited ways. A genuine emergency may delay a hearing, a clear statute may limit it, and courts sometimes excuse a hearing that would make no difference. These exceptions are read narrowly, because fairness is the rule and exclusion is rare.
What is the remedy if natural justice is denied?
The usual remedy is to challenge the order, often by a writ petition in the High Court under Article 226 or the Supreme Court under Article 32. If the court finds a breach, it can set aside the order and send the matter back for a fair process.
