The question of whether to ratify the Mahakali Treaty as is or not had caused a huge stir within the CPN-UML. The treaty presented in the House had been left in limbo due to internal power struggles within the UML. Because, the process of setting and postponing the date for ratifying the treaty continued.

In particular, the different stances taken by the UML leaders on the treaty had not been able to provide a solution. At that time, there was a problem of which UML leader would be considered official. It was also not clear what the stance was. The joint meeting of the Parliament called for Bhadra 31, 2052 was postponed for four days and the discussion on ratifying the treaty was taken forward on a party-by-party basis. In particular, the discord within the then main opposition UML had created great difficulties in ratifying the treaty.

A faction of the UML was opposing it, saying that some of the issues mentioned in the treaty were not in the interest of Nepal. UML leaders CP Mainali and Sahana Pradhan were preparing to go to Delhi to clarify the issue of the treaty. Since the number of MPs to pass the treaty with the ruling party's vote alone was not enough, the consent of the main opposition was necessary for two-thirds.

UML Parliamentary Party Chief Whip Devi Prasad Ojha had said that the UML was ready to pass the treaty and that efforts should be made for national consensus. The ruling party claimed that the opposition UML also had support when signing the treaty with India. Despite discussions in the office of National Assembly Speaker Beni Bahadur Karki in the presence of top leaders of the ruling and opposition parties, no conclusion could be reached. The UML's stance on the issue of passing the treaty was becoming an obstacle.

There was talk that the UML was adopting a strategy to pass the treaty but to convey the message that Nepal benefited and won against India. In the initial meeting on Bhadra 31, 2053, CP Mainali, Radhakrishna Mainali, Bamdev Gautam appeared aggressive on the issue of the treaty. But leaders including Madhav Nepal, KP Sharma Oli appeared soft. But from noon on that day, the aggressive leaders started to fade away. They stopped speaking. A day earlier on Asoj 30, Nepal, Gautam and Mainali had also held discussions with Prime Minister Sher Bahadur Deuba.

UML leaders had also written to Deuba asking for clarity on four issues mentioned in the treaty. Deuba had also replied. But UML leaders demanded that India speak on the issue. UML leaders had put forward the demand that India guarantee Nepal's electricity purchase. The issue of choosing English words like 'will' and 'syaal' included in the treaty was also raised. UML leaders had said that it was necessary to be sure about which words should be put in which place. Gautam and Radhakrishna had urged the government to consider the possibility of imposing a price since Nepal's electricity market is only in India.

MPs Pradeep Giri and Hridayesh Tripathi had said that the House could be adjourned even if it took seven days to get the UML to agree and ratify the treaty. But there was confusion in UML about who the official person was. The Congress President, on the other hand, said that he was not sure who he would talk to in UML. He said, 'Who should we consider the UML leader as official!' All-party meetings were held repeatedly.

UML leaders had requested not to ratify the then treaty. But Congress leaders had raised the question of what to do if the treaty was not ratified even after the postponement. UML leaders had told India to try and explore the issue on their own. One of the UML leaders initially showed some flexibility in the stance he took. But the stance of the UML leaders was not uniform. Therefore, it was difficult to reach a decision-making process and confirm the UML's stance.

Kantipur Daily published a news article on October 1, 2006, focusing on the issue of the Mahakali Treaty, which could not be decided even after being submitted to the parliament due to internal disputes within the main opposition party, UML, under the title 'Mahakali Treaty Case: Joint House Adjourned Again for Four Days'. In addition, another news article was published in Kantipur on the same day, focusing on the issue of the Mahakali Treaty, under the title 'CP Suddenly Silent After Monday Afternoon'.
