Although it enjoyed de facto independence, Dadra and Nagar Haveli were still recognised internationally (e.g. by the International Court of Justice) as Portuguese possessions. The residents of the former colony requested the government of India for administrative help. K.G. Badlani, an officer of the Indian Administrative Service (IAS) was sent as the administrator.
From 1954 to 1961, the territory was administered by a body called the Varishta Panchayat of Free Dadra and Nagar Haveli.
In 1961 when Indian forces took over Goa, Daman, and Diu, Badlani was, for one day, designated the Prime Minister of Dadra and Nagar Haveli, so that, as Head of State, he could sign an agreement with the Prime Minister of India, Jawaharlal Nehru, and formally merge Dadra and Nagar Haveli with the Republic of India.
