In a historic pact between India and Bangladesh, 51 Bangladeshi enclaves (Chhitmahals) in Indian Territory and 111 Indian enclaves in Bangladesh territory were exchanged with effect from 31st July, 2015. The move altered the geography and demography of the district of Cooch Behar in West Bengal. With a view to carry out consequential geographic and demographic alterations vis-à-vis the electoral mosaic of the affected areas, the Election Commission requested to amend section 11 of the Delimitation Act, 2002 and section 9 of the Representation of the People Act, 1950 to enable it to carry out limited delimitation of constituencies in the affected areas. Since the newly acquired area consequent upon the exchange of territory between India and Bangladesh has become the part of the Indian territory, it is required to make delimitation exercise within the limited constituency area before the ensuing State Assembly elections in West Bengal. Accordingly, the Election Laws (Amendment) Bill, 2016 has been proposed for enactment.
