Principle of Natural Justice in Nepal (2026): Audi + Nemo Judex

Natural justice is the procedural backbone of every fair adjudication in Nepal. It is not a single statute and not a single doctrine — it is a pair of inherited common-law principles, fused with the constitutional fair-trial guarantee in Article 21 of the Constitution of Nepal 2072, that together set the minimum procedural standard any court, tribunal, administrative authority or disciplinary body must meet before deciding a matter that affects a person's rights, liberty, property or livelihood. Breach of natural justice is not a mere technical defect; it is a jurisdictional defect that allows the affected party to ask the High Court or Supreme Court to quash the decision through a writ of certiorari and to order a re-hearing through mandamus.

This 2026 (2083 BS) practitioner's guide explains the two pillars of natural justice — audi alteram partem (hear the other side) and nemo judex in causa sua (no one shall be a judge in their own cause) — and walks through how they apply in civil proceedings, criminal proceedings under the Criminal Procedure Code 2074, administrative decisions, quasi-judicial tribunals, and professional disciplinary bodies (Nepal Bar Council, Nepal Medical Council, regulatory and revenue tribunals). It covers the three classical categories of bias (pecuniary, personal, subject-matter), the duty to give reasoned decisions, the right to legal representation, the narrow statutory exceptions, and the writ remedies available where the principles are breached.

What does the principle of natural justice mean under Nepali law?

Natural justice is the body of procedural rules that any forum exercising judicial or quasi-judicial power must follow before it determines a matter affecting a person. The rules are inherited from English common law but in Nepal they are not floating doctrine — they are anchored in the Constitution of Nepal 2072. Article 21 secures the right to fair trial; Articles 20-22 set out further accused-person protections; Article 18 secures equality before the law. Together these articles convert the common-law principles into fundamental rights enforceable by writ under Articles 133 and 144.

The Supreme Court of Nepal has consistently held that natural justice is not an optional add-on to procedure. Where a forum acts without notice, without hearing, or before a biased decision-maker, its decision is void for want of jurisdiction — even if the decision is otherwise correct on the merits. Procedural fairness is, in this sense, prior to substantive justice: a correct outcome reached unfairly is no outcome at all.

What are the two pillars of natural justice?

The two pillars are stated in their classical Latin form because they remain the most precise expression of the rules and they are the form in which Nepali courts and counsel cite them.

• Audi alteram partem — "hear the other side". No person should be condemned, penalised or have their interests adversely affected without first being told what is alleged and being given a fair opportunity to answer.
• Nemo judex in causa sua — "no one shall be a judge in their own cause". The decision-maker must have no interest in the outcome — financial, personal or institutional — and must come to the matter with an open mind.

The two pillars are independent but complementary. A hearing before a biased judge is no hearing at all. An impartial judge who decides without hearing the affected party still breaches natural justice. Both pillars must be satisfied for the decision to stand.

Audi alteram partem — the right to be heard

The first pillar has several practical components recognised in Nepali jurisprudence:

• Right to notice. The person must be told what is alleged against them, with enough detail and enough time to prepare a meaningful response. A vague summons that gives no particulars is not notice in law.
• Right to know the evidence. The decision-maker cannot rely on documents, reports or witness statements that the affected person has not seen. Reliance on undisclosed material is a classic ground of writ challenge.
• Right to a hearing. The affected person must have an opportunity to present their case — through written submissions, oral hearing, or both, depending on what is proportionate to the matter.
• Right to cross-examine. Where adverse evidence is given by a witness, the affected person must in serious matters have the right to test that evidence through cross-examination.
• Right to representation. In criminal matters under Article 20 of the Constitution, the right to a lawyer is express. In serious administrative and disciplinary matters, Nepali courts have routinely extended the right.

The depth of these components scales with the seriousness of the matter. A minor licence renewal may require only written submissions; a disciplinary proceeding that could end a person's professional career requires the full menu — notice, document inspection, oral hearing, cross-examination, representation, reasoned decision.

Nemo judex in causa sua — the rule against bias

The second pillar guarantees an impartial decision-maker. Nepali courts recognise three classical categories of bias:

• Pecuniary bias. The decision-maker has a financial interest in the outcome — they own shares in a party, they stand to gain from a contract, they will be paid more if they decide one way. Even a small pecuniary interest disqualifies; the Supreme Court has applied the "no matter how small" rule consistently with Anglo-Indian jurisprudence.
• Personal bias. The decision-maker is related to, friends with, in conflict with, or has prior history with one of the parties. Family relationships, prior employment, public statements about the matter and demonstrated hostility all fall into this category.
• Subject-matter bias. The decision-maker has prejudged the merits — they have published a view on the issue, they have a strong policy preference, or they have already decided a related case in a way that locks them into a position on this one.

The test the Supreme Court applies is not whether actual bias is proved but whether there is a "real likelihood" or "reasonable apprehension" of bias in the mind of a reasonable observer. Justice must not only be done; it must manifestly and undoubtedly be seen to be done. Where a reasonable observer would suspect bias, the decision is liable to be quashed.

Article 21 of the Constitution — the constitutional anchor

Article 21 of the Constitution of Nepal 2072 guarantees every person the right to a fair trial by a competent court or judicial body. Although the Article is often discussed in the context of criminal proceedings, the Supreme Court has held that the fair-trial guarantee extends to any adjudicatory or quasi-judicial process whose outcome affects a person's substantive rights. Article 20 strengthens this by giving every arrested person the right to legal representation, the right to be produced before a court within twenty-four hours, and the right to silence; Article 22 prohibits torture; Article 18 secures equality before the law.

The convergence between these articles and the common-law principles is the doctrinal foundation of natural justice in Nepal. Where the Constitution speaks of fair trial, the courts read into it the audi alteram partem and nemo judex requirements; where it speaks of equality before the law, the courts read in the impartial-decision-maker requirement. A breach of natural justice is therefore framed in modern writ petitions as a breach of Article 21 (or Article 18, depending on the angle), not as a breach of an unwritten common-law rule.

Where does natural justice apply?

Natural justice applies wherever a forum makes a decision that affects a person's rights, liberty, property, livelihood or reputation. The forum need not be a court — it can be any body exercising judicial or quasi-judicial power. The principles apply across the following categories:

• Civil proceedings. The District Courts, High Courts and Supreme Court all observe natural justice as part of the National Civil Procedure Code 2074 framework — service of summons, opportunity to file written statement, hearing, evidence rules and reasoned judgment.
• Criminal proceedings. The Criminal Procedure Code 2074 codifies many natural-justice requirements: notice of charges, right to counsel, right to call and cross-examine witnesses, prohibition on retrial for the same offence, reasoned judgment.
• Administrative decisions. Decisions of ministries, departments, district administration offices, local levels, and statutory authorities affecting a person — licence cancellation, registration refusal, blacklisting, removal from a list — must follow natural justice. The fact that the decision is "administrative" rather than judicial does not exempt the body.
• Quasi-judicial tribunals. Revenue Tribunals, Labour Court, Foreign Employment Tribunal, Debt Recovery Tribunal, Administrative Court and others established under Article 152 of the Constitution and specific statutes operate under natural-justice standards.
• Professional disciplinary bodies. The Nepal Bar Council under the Nepal Bar Council Act, the Nepal Medical Council, the Nepal Engineering Council, the Nepal Chartered Accountants Institute and similar bodies must observe natural justice when adjudicating member complaints, disciplinary proceedings and licence cancellations.
• Educational and regulatory bodies. University disciplinary committees, securities and insurance regulators, telecommunications and broadcasting regulators, and similar bodies are all bound when their decisions affect rights.

Knowing whether a forum is "judicial", "quasi-judicial" or "purely administrative" used to matter — natural justice applied to the first two but not the third. Modern Nepali jurisprudence has collapsed this distinction. The test today is the effect of the decision on the affected person, not the label of the forum. Any decision affecting rights triggers natural-justice duties.

The right to a reasoned decision

A decision without reasons is a decision the affected person cannot challenge effectively, because they cannot tell why they lost. The duty to give reasoned decisions is now a recognised component of natural justice in Nepal — not because it appears in a single statute, but because the Supreme Court has consistently held that arbitrariness is the opposite of justice, and only a reasoned decision can be tested for arbitrariness.

What counts as adequate reasons varies by context. A District Court judgment must set out the facts found, the law applied, the issues decided and the conclusion with respect to each issue. An administrative order may set out reasons more briefly, but it must link the conclusion to evidence and to a legal source — a citation to the empowering statute is not enough on its own; the order must show how the facts of this case fit the statute. Bare conclusions ("application rejected") with no engagement with the affected person's submissions are routinely quashed on writ.

The right to legal representation

The right to legal representation is express in Article 20 for arrested and accused persons. Beyond that, the right is not absolute — it depends on the seriousness of the matter and the complexity of the issues. In a routine administrative matter where a person can adequately represent themselves, the right may not be triggered. In a disciplinary proceeding that could end a person's career, in a regulatory enforcement action with substantial financial penalty, or in any proceeding involving complex legal issues, the courts have routinely extended the right.

Where the right applies, the affected person must be given a reasonable opportunity to instruct a lawyer of their choice, to consult that lawyer in private, and to be represented by that lawyer at the hearing. A blanket prohibition on legal representation in disciplinary or tribunal proceedings is constitutionally suspect and has been struck down in writ proceedings on multiple occasions.

Exceptions and limitations to natural justice

Natural justice is not absolute. The Supreme Court has recognised a small set of narrow exceptions where the principles do not apply or apply in modified form:

• Genuine emergency. Where the situation requires immediate action to prevent imminent harm — public health emergencies, financial-system risk, public order — a hearing before action may be dispensed with, but a post-decisional hearing is normally required to cure the procedural gap.
• Express statutory exclusion. A statute may exclude or modify natural justice for a specific class of decisions, but the exclusion must be clear and the statute must itself meet constitutional standards. A statute that purports to authorise arbitrary action without any procedural protection is itself open to constitutional challenge under Article 21.
• Pure policy decisions. Where the decision is one of general policy rather than the application of a rule to a specific person — for example, setting national fiscal targets — natural justice does not apply, because no specific person's rights are affected by the policy itself (only by its later individual application).
• Confidential intelligence and national security. Where disclosure of evidence would compromise national security, the courts have accepted modified procedures with closed material, but the limitation is narrowly construed and never extends to denying notice of the gist of the case altogether.
• Useless formality. Where giving a hearing would be a useless formality because the facts are admitted and the legal consequence is automatic, the hearing requirement may be relaxed — but this exception is treated by the courts with great caution.

The pattern across all exceptions is that the courts narrow them in application. The default is that natural justice applies; the burden of showing an exception lies on the body relying on it.

Remedies for breach — certiorari and mandamus

Where a decision-maker has breached natural justice, the affected person's primary remedy is a writ petition before the High Court (under Article 144) or, for matters of constitutional and public importance, the Supreme Court (under Article 133). Two writs are most commonly used:

• Certiorari — a writ that quashes the impugned decision. The court does not substitute its own decision on the merits; it sets aside the procedurally defective decision and the matter returns to the original body (often with directions on what natural-justice steps must be followed in the re-hearing).
• Mandamus — a writ that commands a public body to perform a duty. Combined with certiorari, mandamus is used to direct the body to re-hear the matter fairly, to consider a fresh application, or to give the affected person the procedural protections the law requires.

Other writs that can be relevant in natural-justice cases include prohibition (preventing an unfair forthcoming hearing from continuing), habeas corpus (where unlawful detention is the consequence of an unfair procedure) and quo warranto (challenging the very authority of the decision-maker to act). In severe cases, the High Court or Supreme Court may also award damages against the public body for losses caused by the procedural breach. For details on filing a writ in Nepal, see our guide on the writ procedure in Nepal.

Natural justice in administrative tribunals and disciplinary bodies

Administrative tribunals constituted under Article 152 of the Constitution — the Administrative Court, the Revenue Tribunal, the Labour Court, the Foreign Employment Tribunal, the Debt Recovery Tribunal — and disciplinary bodies under statute — the Nepal Bar Council, the Nepal Medical Council and others — operate under enabling acts that prescribe their procedures. Those procedures must satisfy natural justice or risk constitutional challenge.

The most common natural-justice failures we see in tribunal and disciplinary practice are: cursory notice that does not particularise the allegations; reliance on inspector or investigator reports that the affected person has not seen; refusal to allow cross-examination of adverse witnesses; refusal of legal representation; perfunctory hearings; and decisions that recite the conclusion without engaging with the affected person's submissions. Each of these failures, taken alone, can be enough to support a writ challenge; in combination they make a writ almost certain to succeed.

The role of natural justice in criminal procedure

The Criminal Procedure Code 2074 codifies natural-justice requirements for criminal trials in detail: filing of the chargesheet, supply of investigation documents to the accused, framing of charges with reasons, opportunity to file response, examination and cross-examination of witnesses, right to counsel under Article 20, reasoned judgment with findings on each charge, and right of appeal. Most natural-justice failures in criminal procedure are caught at trial or first appeal stage; writ challenges to criminal trial procedure are less common in Nepal because of the developed appellate pathway. The natural-justice framework remains important, however, as the constitutional yardstick against which any new criminal procedure statute is measured. See our companion article on the procedural rights of defendants in Nepal for the full set of trial-stage protections.

How can Alpine Law Associates help with natural-justice matters?

Alpine Law Associates handles natural-justice issues across the litigation lifecycle. We file writ petitions before the High Courts and the Supreme Court of Nepal to quash decisions taken in breach of audi alteram partem or nemo judex in causa sua — by tribunals, disciplinary committees, regulatory authorities, district administration offices, ministries and local levels. We defend writ petitions on behalf of public bodies that have followed proper procedure and need to show the court the record. We represent clients in disciplinary proceedings before the Nepal Bar Council, Nepal Medical Council and similar bodies, ensuring the natural-justice protections are claimed and enforced at the proceeding itself rather than only afterwards on writ.

As a full-service law firm in Nepal, we also co-ordinate natural-justice work with related fundamental-rights litigation and jurisdiction challenges in a single counsel relationship. Where the breach is severe and ongoing, we can move quickly to seek interim relief stopping the unfair process before the substantive decision is taken, which is often more valuable than quashing the decision after it has caused harm.
