In 1987, 1991 and 1996 Nambadan contested from Irinjalakuda constituency as an Independent candidate backed by the LDF. Nambadan served as Transport Minister from 25 January 1980 to 20 October 1981 and as Housing Minister from 2 April 1987 to 17 June 1991, both terms when E. K. Nayanar was the Chief Minister. Nambadan had long fought for the declaration of Malayalam as the official language used in official transactions of the state. He had burnt English copies of legislative bills in the Assembly hall and his supporters had to undergo several days of imprisonment for shouting slogans demanding introduction of Malayalam as official language. A formal declaration to this effect was made by the state government in 2012.
