Thereafter British parliament passed the Indian Independence Act, 1947 on 15 July 1947 and the Bill received Royal Assent on 18 July 1947. This act provided for the creation of independent dominion of India and Pakistan on 15 Aug 1947. This act also freed the Indian states from the suzerainty of British Government. There were a lot of misgivings about the lapse of suzerainty and the resultant freedom given to the over 560 Indian States. Indian leaders drafted an Instrument of Accession asking the Rulers to accede to the dominion government on three subjects of Defence, Communication and External affairs. Maharaja of Mysore executed the Instrument of accession on 9 Aug 1947 and the same was accepted by the Governor General of India on 16 Aug 1947. But this also gave impetus to the local congress leaders to renew their demand for a Responsible Government. This led to an agitation known as " Mysore Chalo". There appears to be an obfuscation of facts among the agitating public that Mysore Maharaja on the advice of the Dewan and his secretary Sir T. Thamboo Chetty was refusing to join the Indian Union. The truth of the matter was India was not a Union then. India had just become an Independent Dominion. Maharaja of Mysore was one of the earliest to sign the Instrument of accession. Maharaja soon on 24 Sept 1947 gave his assent to setting up of a Responsible Government and on 25 Oct 1947, Mr. K.C. Reddy became the First Chief Minister with a cabinet of nine ministers. But Dewan continued to remain asa link between the Cabinet and the Maharaja. But as Maharaja accepted the recommendation of the Constituent assembly of Mysore to accept the Constitution of India for the state of Mysore and become a Part-B state in the soon to be formed Republic of India, and issued a proclamation to this effect on 25 Nov 1949. With this the post of Dewan was also abolished. During his tenure as Diwan of Mysore, Mudaliar organised a number of Tamil music concerts in the Mysore kingdom in order to raise money for the restoration of Carnatic musician Tyagaraja's samadhi or tomb at Tiruvaiyaru. Ramasamy Mudaliar was sent by Prime Minister Jawaharlal Nehru as head of the Indian Delegation to New York to argue India's case in The Security Council when Hyderabad appealed to it against Accession to India and eloquently argued the case for India and Security council decided in favour of India.
