<P> In the Republic of India, the Madras State Legislative Assembly continued to be the lower house in a bicameral legislature . The first election to the assembly on the basis of universal adult suffrage was held in January 1952 . According to the Delimitation of Parliamentary and Assembly Constituencies (Madras) Order, 1951, made by the President under sections 6 and 9 of the Representation of the People Act, 1950, the assembly's strength was 375 members elected from 309 constituencies . Out of the 309 constituencies in the undivided Madras State, 66 were two member constituencies, 62 of which had one seat reserved for Scheduled Caste candidates and 4 for Scheduled Tribe candidates . The two member constituencies were established in accordance to Article 332 of the Indian Constitution . The voting method and the plurality electoral formula were defined in The Representation of People Act, 1950 . These constituencies were larger in size and had greater number of voters (more than 1, 00,000) when compared to general constituencies . Multiple members were elected only in the 1952 and 1957 elections as double member representation was abolished in 1961 by the enactment of Two - Member Constituencies Abolition Act (1961). Of the 375 seats, 143 were from what later became Andhra state, 29 were from Malabar, 11 from South Canara (part of present - day Karnataka) and the remaining 190 belonged to Tamil Nadu . </P> <P> On 1 October 1953, a separate Andhra State consisting of the Telugu - speaking areas of the composite Madras State was formed and the Kannada - speaking area of Bellary District was merged with the then Mysore State . This reduced the strength of the Legislative Assembly to 231 . On 1 November 1956, the States Reorganisation Act took effect and consequently the constituencies in the erstwhile Malabar district were merged with the Kerala State . This further reduced the strength to 190 . The Tamil - speaking area of Kerala (present day Kanyakumari district) and Shenkottah taluk were added to Madras State . According to the new Delimitation of Parliamentary and Assembly Constituencies Order 1956, made by the Delimitation Commission of India under the provisions of the State Reorganisation Act of 1956, the strength of the assembly was increased to 205 . The 1957 elections were conducted for these 205 seats . In 1959, as result of The Andhra Pradesh and Madras (Alteration of Boundaries) Act 1959, one member from the Andhra Pradesh Legislative Assembly was allotted to Madras increasing its Legislative Assembly strength to 206 . The 1962 elections were conducted for these 206 seats . In 1965, the elected strength of the assembly was increased to 234 by the Delimitation of Parliamentary and Assembly Constituencies Order, 1965 . In addition to the 234, the assembly also has one nominated member representing the Anglo - Indian community . From 1965, the number of members has remained constant . In 1969, Madras State was renamed Tamil Nadu and subsequently the assembly came to be known as the "Tamil Nadu Legislative Assembly". The Legislative Council was abolished with effect from 1 November 1986 through an Act of Parliament titled as The Tamil Nadu Legislative Council (Abolition) Act, 1986 . With the abolition of the council, the legislature became a unicameral body and remained so for the next 24 years . Of the fourteen assemblies that have been constituted so far, four (the sixth, seventh, ninth and tenth) have been dismissed by the Central Government using Article 356 of the Indian Constitution . In 2004, during the 12th assembly, the ADMK Government under J. Jayalalitha made unsuccessful attempts to shift the assembly, first to the location of Queen Mary's College and later to the Anna University campus, Guindy . Both attempts were withdrawn after public opposition . During the 13th Assembly, the DMK government led by M. Karunanidhi proposed a new plan to shift the assembly and the government secretariat to a new building in the Omandurar Government Estate . In 2007, the German architectural firm GMP International won the design competition to design and construct the new assembly complex . Construction began in 2008 and was completed in 2010 . The new assembly building was opened and the assembly started functioning in it from March 2010 . After ADMK's victory in the 2011 elections, the assembly shifted back to Fort St. George . </P> <P> List of historical locations where the Tamil Nadu Legislature has been housed: </P> <Table> <Tr> <Th> Duration </Th> <Th> Location </Th> </Tr> <Tr> <Td> 1921--1937 </Td> <Td> Council chambers, Fort St. George </Td> </Tr> <Tr> <Td> 14 July 1937--21 December 1938 </Td> <Td> Senate House, Madras University Campus, Chepauk </Td> </Tr> <Tr> <Td> 27 January 1938--26 October 1939 </Td> <Td> Banqueting Hall (Rajaji Hall), Government Estate (Omandurar Estate), Mount Road </Td> </Tr> <Tr> <Td> 24 May 1946--27 March 1952 </Td> <Td> Council chambers, Fort St. George </Td> </Tr> <Tr> <Td> 3 May 1952--27 December 1956 </Td> <Td> Kalaivanar Arangam, Government Estate (Omandurar Estate) </Td> </Tr> <Tr> <Td> 29 April 1957--30 March 1959 </Td> <Td> Assembly Hall, Fort St. George </Td> </Tr> <Tr> <Td> 20--30 April 1959 </Td> <Td> Aranmore Palace, Udhagamandalam </Td> </Tr> <Tr> <Td> 31 August 1959--11 January 2010 </Td> <Td> Assembly Hall, Fort St. George </Td> </Tr> <Tr> <Td> 16 March 2010--15 May 2011 </Td> <Td> New Assembly Complex, Omandurar Government Estate, Anna Salai </Td> </Tr> <Tr> <Td> 16 May 2011--present </Td> <Td> Assembly Hall, Fort St. George </Td> </Tr> </Table>
