Although claimed by Nepal, Kalapani has been administered by Indian army since the 1962 border war with China and Indian maps have been showing Kalapani as part of India since long time. The 1816 Treaty of Sugauli signed by Kingdom of Nepal and British India in 1816 utilizes the Kali River as Nepal's western boundary with India. However, lack of consensus on what is the precise location of the river Kali has resulted in dispute over whether the land consisting Kalapani, Limpiyadhura and Lipulekh is part of India or Nepal. Some scholars suggest that the lack of consensus is because of British cartographers who kept on shifting the line demarcating the river eastwards for strategic reasons. However, there are also some scholars who believe that lack of consensus is due to the shift in the course of the river over time.
