In 1963, Jawahar Lal Nehru appointed one man Commission under Justice Sudhi Ranjan Das to investigate the charges against Kairon.
[6] First No-confidence motion In a case, Partap Singh Kairon vs. State of Punjab, the Supreme Court of India in its judgment made some adverse comments on the conduct of the Chief Minister of Punjab; due to this, the Leader of Opposition Gurnam Singh brought a No-confidence motion against the Government.
On 19 September, shortly before the Chief Minister rose to take part in debate, opposition benches walked out in protest.
[7] Second No-confidence motion On 13 March 1964, shortly after question hour, the Speaker announced that he received numbers of no-confidence motions against the Kairon Government, by Comrade Ram Chandra (Prajatantra Party), Devi Lal and Bachan Singh (Independent), Gurcharan Singh (Akali Dal), Baldev Prakash (Bharatiya Jana Sangh), Comrade Jangir Singh (Communist Party of India) and some other opposition legislators.
He had also abused power through his colleagues and subordinates to help his sons and relatives to acquire and dispose of properties or business in violation of law rules of established procedures.
Pratap Singh Kairon accepted with all humility and the verdict of the commission and put the blame on his son for all the corruption.
[12] In reaction to the committee's recommendation to the central government of a state with Punjabi as its official language on 9 March 1966, there were strikes, arson and murder, including 3 Congressmen burnt alive in Panipat, including an old associate of Bhagat Singh, generally believed to have been orchestrated by the Jan Sangh, who still opposed the Punjabi Suba.
[14][15][16][17] To initiate and finish the smooth reorganisation of Punjab on the basis of Punjabi language, Central Congress Leadership directed Ram Kishan to resign and he did the same and on 5 July 1966 Punjab assembly suspended and President's rule was imposed till 1 November 1966.
The Punjab Reorganisation Act, 1966 was passed on 18 September in the Lok Sabha, and on 1 November 1966, a Punjabi-speaking state became a reality.
[18] Therefore, Congress Party elected Giani Gurmukh Singh Musafir, who once served as Jathedar of Akal Takht, as Chief Minister of Punjab.
