<P> Madras State was renamed as Tamil Nadu (Tamil for Tamil country) on 14 January 1969 . The legislative assembly adopted a resolution on 14 May 1986, to abolish the legislative council . Thereafter, the legislative council was abolished through an act of Parliament named the Tamil Nadu Legislative Council (Abolition) Act, 1986 with effect from 1 November 1986 . The state legislature is unicameral, and consists of 235 members including one nominated member . </P> <P> The Chief Minister commands most of the executive powers while the Governor has a largely ceremonial role . The Chief Minister of Tamil Nadu, like other Chief Ministers of India, is elected by legislators of the political party or the coalition which commands a simple majority in the legislative assembly . The tenure of the Chief Minister extends as long as he or she enjoys the confidence of the assembly . The incumbent shall vacate the office in the event of a successful motion of no confidence . Also, the President of India, acting under the recommendations of the Cabinet of Ministers of the Government of India, can dismiss an elected government using certain provisions of Article 356 of the Constitution of India . In 1976, Karunanidhi's government was dismissed and President's rule was imposed on the grounds of corruption . If a vacancy is caused to the office of the Chief Minister due to death, demitting, or dismissal, the Governor can invite another person to form the government and request him or her to move a confidence - seeking motion in the Assembly . In the event of no one enjoying majority support, the Assembly is either dissolved or put in suspended animation and the state comes under President's rule or a caretaker government until fresh elections are held for the assembly . The incumbent shall be disqualified if convicted of a criminal offence with a jail sentence of two years or more . In 2014, Jayalalithaa lost her post due to a special court sentencing her to four years of prison term in the disproportionate assets case . </P> <Table> <Tr> <Th_colspan="2"> #</Th> <Th> Name </Th> <Th> Portrait </Th> <Th> Took office </Th> <Th> Left office </Th> <Th> Term </Th> <Th> Political party </Th> <Th> Election </Th> </Tr> <Tr> <Th> </Th> <Td> </Td> <Td> C.N.
