Treaty Ratification in Nepal: Article 279 & the Two-Thirds Rule
Nepal makes an international treaty binding through parliamentary ratification under Article 279 of the 2015 Constitution and the Nepal Treaty Act 2047 (1990). Treaties on peace and friendship, security and strategic alliance, national boundaries, and natural-resource sharing require a two-thirds majority of the total members of both houses of the Federal Parliament; ordinary treaties need only a simple majority of the House of Representatives. This explainer covers the rules, the procedure, and worked examples such as the Mahakali Treaty and the MCC compact.

How Nepal turns an international treaty into binding law
In Nepal, signing an international treaty is not enough to make it legally binding. A treaty becomes enforceable only after it has been ratified, acceded to, accepted or approved through the process set out in the Constitution and in the Nepal Treaty Act, 2047 (1990). Until that happens, an agreement the government has signed remains a political commitment rather than a source of domestic law. This is why almost every controversial foreign deal in Nepal, from hydropower treaties to development compacts, eventually turns on a single question: does Parliament have to ratify it, and if so, by what majority?
The governing constitutional provision today is Article 279 of the Constitution of Nepal, 2015 (2072 Bikram Sambat). It says that ratification, accession, acceptance or approval of treaties to which Nepal or the Government of Nepal is to become a party 'shall be as determined by the law', and then fixes the voting thresholds that any such law must respect. The detailed procedure, definitions and consequences are supplied by the Nepal Treaty Act, 2047, which remains in force. The stakes are high because, once ratified by Parliament, a treaty's provisions are treated almost like domestic statute: if a ratified treaty conflicts with an existing Nepali law, the treaty prevails to the extent of the inconsistency. That elevation of treaty text above ordinary legislation is precisely why the Constitution reserves the most sensitive categories of treaty for a demanding two-thirds vote.
Article 279 of the 2015 Constitution, clause by clause
Article 279 has four clauses. Clause (1) states that ratification of, accession to, acceptance of or approval of any treaty to which Nepal is to become a party shall be as determined by law, delegating the mechanics to the Treaty Act. Clause (2) is the heart of the article: it requires that ratification of treaties on four listed subjects be done 'by two-thirds majority of the total members in both houses of the federal legislature'. Those four subjects are (a) peace and friendship, (b) security and strategic alliance, (c) the boundaries of Nepal, and (d) natural resources and the distribution of their uses.
A crucial proviso to clause (2) softens the rule for two of the four categories. It allows a simple majority of the members present in the House of Representatives (the Pratinidhi Sabha) to ratify an 'ordinary type' of treaty falling under sub-clauses (a) peace and friendship or (d) natural resources, provided the treaty does not have a 'wide, grave or long-term impact on the nation'. Read carefully, this means the two-thirds route is mandatory and cannot be downgraded for (b) security and strategic alliance and (c) boundaries; only the peace-and-friendship and natural-resource categories admit a lighter, simple-majority path for minor agreements.
Clause (3) makes ratification a precondition of enforcement: no agreement or treaty concluded after the Constitution came into force may be implemented by the Government or the State of Nepal unless it has been ratified, acceded to, accepted or approved under Article 279. Clause (4) sets an outer limit that no majority can override, providing that notwithstanding clauses (1) and (2), there shall be no treaty that adversely affects the regional (territorial) integrity of Nepal. Together these clauses make treaty-making a shared act of the executive and the legislature, hedged by a non-negotiable red line on territory.
- Peace and friendship (shanti ra maitri) — two-thirds, but simple majority possible if the treaty is ordinary and low-impact
- Security and strategic alliance (suraksha ra sandhi) — always two-thirds of total members of both houses
- Boundaries of Nepal (seemaana) — always two-thirds of total members of both houses
- Natural resources and distribution of their uses (prakritik srot) — two-thirds, but simple majority possible if ordinary and low-impact
- All other, ordinary treaties — simple majority of the House of Representatives
What 'two-thirds' means and how the joint sitting works
The two-thirds test in the 2015 Constitution is measured against the total number of members of both houses of the Federal Parliament, namely the House of Representatives (Pratinidhi Sabha, 275 seats) and the National Assembly (Rastriya Sabha, 59 seats). Because the threshold is calculated on the combined membership sitting together, treaty ratification for the four sensitive classes takes place at a joint sitting of the two houses rather than in the House of Representatives alone. This is a far higher bar than the simple majority of members present that suffices for ordinary agreements.
The distinction matters in practice because coalitions that command a comfortable simple majority may still fall well short of two-thirds. A government can pass an ordinary treaty on its own numbers, but a peace-and-friendship, security, boundary or major resource-sharing treaty generally needs cross-party support, forcing national consensus on the categories of treaty most likely to affect sovereignty, security and shared rivers.
The two-thirds treaty threshold sits alongside, but is separate from, the two-thirds majority that Article 274 requires to amend most of the Constitution. Loksewa (Public Service Commission) study guides often group the two together as 'the two-thirds rules', but they differ: Article 274 protects the Constitution from casual amendment, while Article 279 protects sovereignty-sensitive treaties from ratification on a bare majority.
The Nepal Treaty Act, 2047 (1990): the operating manual
The Nepal Treaty Act, 2047 supplies the procedure that the Constitution only sketches. Authenticated on 1 Mangsir 2047 (11 November 1990) and deemed to have come into force from Kartik 23, 2047 (9 November 1990), the fourteen-section Act was originally enacted under the 1990 Constitution and continues to apply, with subject-references updated by later constitutional changes. Section 2 defines a 'treaty' broadly as any written agreement between two or more states, or between a state and an inter-governmental organisation, whatever the document is called, and also defines 'full power', 'reservation' and 'denunciation'.
Section 3 restricts who may commit Nepal: no one except the Prime Minister and the Minister for Foreign Affairs may negotiate, accept a final draft, sign, or maintain reservations without a formal grant of 'full power', although ambassadors and heads of delegation enjoy limited authority within their posting or conference. Sections 4 and 5 set the ratification procedure. For ordinary treaties, the Government tables a resolution in the House of Representatives, which adopts it by a majority of members present; for the sensitive classes reserved by the Constitution, the resolution goes to the full Parliament for the higher vote.
Section 9 is the provision that gives ratified treaties their bite: where a treaty ratified, acceded to, accepted or approved by Parliament is inconsistent with prevailing Nepali law, the inconsistent law is void for the purpose of that treaty and the treaty provisions are enforceable 'as good as' Nepalese laws. Section 12 requires that treaties ratified or approved by Parliament be published in the Nepal Gazette (Nepal Rajapatra) within sixty days. Sections 6, 7, 10 and 11 deal with executive-signed treaties, denunciation or suspension, laying such treaties before the House for information, and optional registration with the United Nations.
- Section 3 — only the Prime Minister and Foreign Minister may act without a written 'full power'
- Sections 4-5 — the Government tables a ratification resolution in Parliament
- Section 9 — ratified treaties override inconsistent domestic law to the extent of the conflict
- Section 12 — parliament-ratified treaties must be published in the Nepal Gazette within 60 days
- Section 6 — some treaties may be signed and enforced by executive decision without ratification
From Article 126 (1990) to Article 156 (2007) to Article 279 (2015)
The two-thirds ratification rule is not new to the 2015 Constitution; it has been a fixed feature of Nepal's constitutional order since the restoration of multiparty democracy. Article 126 of the Constitution of the Kingdom of Nepal, 1990 (2047 BS) first introduced parliamentary ratification and listed the very same four sensitive subjects: peace and friendship; defence and strategic alliance; boundaries of the Kingdom of Nepal; and natural resources and the distribution of their uses. It required a two-thirds majority of the members present at a joint sitting of both Houses of Parliament, with a proviso allowing a simple majority of the House of Representatives for ordinary treaties under the peace-and-friendship and natural-resource heads.
When the monarchy was suspended and later abolished, the Interim Constitution of Nepal, 2063 (2007) carried the provision over almost verbatim as Article 156, preserving both the list of four subjects and the two-thirds joint-sitting requirement. The 2015 Constitution restated the rule as Article 279, updating the language of 'defence' to 'security and strategic alliance' and measuring the two-thirds threshold against the total membership of both federal houses rather than the members merely present. The substance, however, is a straight line across three constitutions.
This continuity matters for interpreting older treaties: the Mahakali Treaty was ratified under Article 126 of the 1990 Constitution, but the analysis is essentially the one that would apply under Article 279 today. When commentators, Loksewa answer keys and newspaper explainers discuss 'the two-thirds rule', they are describing a single, durable constitutional idea simply renumbered as Nepal's constitutions changed.
Worked example 1: the Mahakali Treaty's midnight two-thirds vote
The clearest illustration of the two-thirds route is the Mahakali Treaty, formally the Treaty between His Majesty's Government of Nepal and the Government of India Concerning the Integrated Development of the Mahakali River, signed in New Delhi on 12 February 1996. Because it concerned the sharing and use of a shared river, it fell squarely within the natural-resources category of Article 126(2)(d) and, given its far-reaching and long-term impact, was treated as requiring the full two-thirds threshold rather than the simple-majority proviso.
The treaty was ratified late on the night of 20 September 1996, when a joint sitting of the two houses of Parliament approved it by the required two-thirds majority. The near-midnight vote, after intense debate and internal splits within the then-ruling CPN (UML), gave the episode its lasting nickname as the 'midnight vote' and made Mahakali the first bilateral treaty ratified by two-thirds under the 1990 Constitution.
The ratification is also remembered for four so-called 'national strictures' (rastriya sankalpa) said to have been attached as conditions, covering the pricing and export of energy, the formation of a Mahakali River Commission, equal sharing of the river's waters, and the status of the river as a boundary river. Later scrutiny found these strictures were widely believed but not formally registered or passed as part of the parliamentary resolution, a discrepancy that still fuels debate over the treaty's implementation. Mahakali thus shows both the power and the limits of the two-thirds process: a supermajority can bind the nation, but the precise terms of that consent can later be contested.
Worked example 2: the MCC compact and the ratification debate
The Millennium Challenge Corporation (MCC) Nepal Compact, a United States grant of 500 million US dollars (with an additional Nepali contribution of about 130 million dollars) for electricity transmission lines and road maintenance, produced the most contested ratification debate of recent years. Signed in Washington in September 2017, the compact sat in Parliament from 2019 amid street protests and claims that it was a security or strategic instrument that would require a two-thirds vote, or even that it needed to be treated as a treaty overriding Nepali law.
Parliament finally ratified the compact on 27 February 2022. Rather than routing it through a two-thirds joint sitting as a security or strategic-alliance treaty, the ruling coalition passed it in the House of Representatives by majority, accompanied by a twelve-point 'interpretive declaration'. That declaration recorded Nepal's own understanding of the compact, stating among other things that it is not part of any United States security or Indo-Pacific strategy and that Nepal's Constitution prevails over the compact, and providing that Nepal could terminate the agreement if it operated beyond the declaration.
The MCC episode neatly frames the recurring legal question. Supporters argued the compact was an ordinary economic assistance agreement that did not fall within Article 279's security or strategic-alliance class, so a simple majority was sufficient; critics argued that its supremacy-over-domestic-law effect and alleged strategic character demanded a two-thirds vote. The interpretive declaration was the political device that let the government ratify by simple majority while formally denying any security dimension. Whatever one's view, MCC shows how the classification of a treaty, not just the counting of votes, is where Nepal's ratification battles are actually won and lost.
Treaty Ratification in Nepal: Article 279 & the Two-Thirds Rule — FAQ
Which treaties need a two-thirds majority in Nepal?+
Under Article 279(2) of the 2015 Constitution, treaties on four subjects need a two-thirds majority of the total members of both houses of the Federal Parliament: peace and friendship, security and strategic alliance, the boundaries of Nepal, and natural resources and the distribution of their uses. Security and boundary treaties always require two-thirds. For peace-and-friendship and natural-resource treaties, an ordinary, low-impact agreement can instead be passed by a simple majority of the House of Representatives.
What does Article 279 of the Constitution of Nepal say about treaties?+
Article 279 says ratification of any treaty Nepal joins must follow the law, sets the two-thirds voting rule for four sensitive treaty classes, and bars implementation of any post-2015 treaty until it is ratified under the article. Its clause (4) also forbids any treaty that adversely affects Nepal's territorial integrity, a limit no majority can override.
What is the Nepal Treaty Act 1990?+
The Nepal Treaty Act, 2047 (1990) is the fourteen-section statute that operationalises constitutional treaty-making. It defines a treaty, limits signing authority to the Prime Minister and Foreign Minister absent a 'full power', sets the resolution-based ratification procedure, makes ratified treaties override inconsistent domestic law, and requires publication in the Nepal Gazette within 60 days. It remains in force under the 2015 Constitution.
Did the MCC compact need two-thirds ratification in Nepal?+
Nepal's Parliament ratified the 500-million-dollar MCC compact on 27 February 2022 by a majority in the House of Representatives, not by a two-thirds joint sitting, alongside a twelve-point interpretive declaration. The government treated it as ordinary economic assistance rather than a security or strategic-alliance treaty; critics disagreed, which is why classification, not just vote counting, drove the dispute.
How was the Mahakali Treaty ratified?+
The Mahakali Treaty with India, signed on 12 February 1996, was ratified late on 20 September 1996 by a two-thirds majority at a joint sitting of Parliament under Article 126 of the 1990 Constitution, because it concerned sharing a boundary river. It was the first bilateral treaty ratified by two-thirds and is remembered for its near-midnight vote and disputed 'national strictures'.
Does a ratified treaty override Nepali law?+
Yes, to the extent of any conflict. Section 9 of the Nepal Treaty Act, 2047 provides that where a treaty ratified by Parliament is inconsistent with prevailing Nepali law, the inconsistent law is void for the purpose of that treaty and the treaty provisions are enforced as if they were Nepalese law. This supremacy effect is a key reason sensitive treaties are reserved for a two-thirds vote.
