Sugauli Treaty missing? Nepal can’t confirm where 1816 document is amid Lipulekh border row
Nepal's Foreign Minister told the House of Representatives that the government holds records relating to the 1816 Treaty of Sugauli but cannot confirm whether any of the preserved copies is the original document.
This is not the first such instance — Nepal was similarly unable to locate the original 1950 Treaty of Peace and Friendship with India during a review around 2016, and a subsequent 2019 investigation could not confirm the authenticity of either treaty's originals without forensic analysis.
The disclosure comes amid a renewed border controversy after Nepal objected to India and China resuming bilateral trade through the Lipulekh Pass, an area Nepal claims lies within its territory (east of the Kali River per its reading of the treaty).
India has maintained decades of administrative control over the area and points out that the trade route through Lipulekh has been in use since 1954.
Treaty of Sugauli (1816) — Origin of the Nepal-India Boundary
The Sugauli Treaty concluded the Anglo-Nepalese War (Anglo-Gorkha War, 1814-1816) between the British East India Company and the Kingdom of Nepal. Signed in December 1815 and ratified in March 1816, it forced Nepal to cede roughly one-third of its territory, fixing the Kali River as Nepal's western boundary with British India.
Key Details
- Article 5 of the treaty states that the "Rajah of Nipal renounces for himself, his heirs, and successors, all claim to or connection with the countries lying to the west of the river Kali" — establishing the river as the boundary but not specifying its exact source.
- Nepal's territory shrank from approximately 267,000 sq km to about 147,000 sq km as a result of the cessions (including Kumaon, Garhwal, most of the Terai, and hill areas up to the Mechi River in the east).
- The treaty's silence on the precise geographic origin of the Kali (also called Mahakali/Sharda) River is the root of the current Kalapani-Lipulekh-Limpiyadhura dispute.
The inability to locate the original signed document adds an evidentiary complication to Nepal's territorial claims, since disputes over the treaty's exact boundary description (and any accompanying maps) rest on textual and cartographic interpretation of this founding document.
Kalapani-Lipulekh-Limpiyadhura Dispute
This is a live territorial dispute over roughly 372 sq km of Himalayan territory at the India-Nepal-China tri-junction, arising from differing identifications of the source of the Kali River referenced in the 1816 treaty.
Key Details
- Nepal contends the Kali River originates at Limpiyadhura, the westernmost source, which would place Kalapani and Lipulekh within Nepali territory.
- India identifies a smaller, more easterly stream near Lipulekh as the river's source, placing the disputed area within Indian territory.
- India has maintained administrative and military presence in Kalapani since 1962 (post the 1962 Sino-Indian war), predating the current diplomatic dispute by decades.
- The dispute escalated sharply in 2020 when India released a new political map depicting Kalapani, Lipulekh, and Limpiyadhura as part of Uttarakhand, prompting Nepal to issue its own map claiming the same territory and to amend its constitution's national emblem to reflect this claim.
- Lipulekh Pass has separately served as a trade and pilgrimage route (Kailash Mansarovar Yatra) between India and the Tibet Autonomous Region of China since 1954 (formalised bilaterally in 2015), which is the specific trigger for the current controversy over renewed India-China trade through the pass.
The renewed objection over India-China trade resumption at Lipulekh is the immediate trigger prompting scrutiny of the treaty's authenticity and interpretation in Nepal's Parliament.
Bilateral Treaties and the Question of Document Authenticity in International Law
Under customary international law and the Vienna Convention on the Law of Treaties (1969), a treaty's validity does not depend on the survival or physical location of the original signed instrument; ratified treaty texts, once registered or otherwise authenticated through state practice and mutual recognition, remain legally binding.
Key Details
- India is not a party to the VCLT 1969 but recognises many of its provisions as reflective of customary international law; treaties predating the VCLT (such as Sugauli, 1816) are governed by the customary law existing at the time and subsequent state practice.
- Loss of an original document typically does not itself void a treaty, since certified or archival copies, along with decades of consistent bilateral conduct (state practice), can serve as evidence of the agreed terms.
- The 1950 Indo-Nepal Treaty of Peace and Friendship — whose original was similarly reported missing around 2016 — continues to be treated as valid and in force by both governments despite the missing original, illustrating this principle in practice.
While the missing original complicates precise boundary interpretation (especially any accompanying maps), it does not by itself invalidate the 1816 treaty's territorial provisions, which both states have relied upon and enforced through state practice for over two centuries.
- Treaty of Sugauli: signed December 1815, ratified March 1816, ending the Anglo-Nepalese War (1814-1816).
- Article 5 of the treaty fixes the Kali River as Nepal's western boundary with British India.
- Nepal's territorial loss under the treaty: from approximately 267,000 sq km to about 147,000 sq km.
- Disputed area (Kalapani-Lipulekh-Limpiyadhura): approximately 372 sq km.
- India's administrative/military presence in Kalapani: since 1962.
- Lipulekh Pass trade route in use since: 1954 (formal bilateral agreement, 2015).
- Prior missing-document precedent: original 1950 Indo-Nepal Treaty of Peace and Friendship also reported untraceable (2016), unresolved as of a 2019 investigation.
