Conn. Gen. Stat. § 2-14

The General Assembly shall enact no special legislation relative to the powers, organization and form of government of any town, city, borough or other unit of local government unless requested by a town, city, borough or other unit of local government, in the manner hereinafter prescribed, to enact such special legislation. A resolution requesting the General Assembly to enact special legislation and specifying the purpose of such legislation shall be adopted: (1) By a two-thirds vote of the council or board of directors in any town having such a body; of the board of aldermen, council or body charged with the duty of making annual appropriations in any city or consolidated town and city; of the board of burgesses in any borough or consolidated town and borough; or of the board of directors or district committee in any district; or (2) by the board of selectmen or by a majority vote of the town meeting or representative town meeting in any town not having a council or board of directors. A request for the enactment of special legislation by the General Assembly may also be initiated by a petition specifying the purpose of such legislation and signed by not less than ten per cent of the electors of the town, city, borough or other unit of local government as determined by the last-completed registry list and filed with the clerk of such town, city, borough or other unit of local government. Upon the filing of such petition, such clerk shall proceed forthwith to determine its sufficiency by comparing the names thereon with those contained in such registry list and shall certify its sufficiency or insufficiency. Such clerk shall file with the Secretary of the State, not later than ten days prior to the convening of any session of the General Assembly in which such proposed legislation is to be introduced, a certified copy of the resolution as adopted or the text of the petition as signed.
