Conn. Gen. Stat. § 9-169a
For the purposes of this section and section 9-169, "split voting district" means a voting district which was divided by statute or otherwise divided by law pursuant to article 26 of the amendments to the Constitution of Connecticut or an order of a court of competent jurisdiction between two or more congressional, senatorial or assembly districts within a town so that a part of such split voting district was allocated to one congressional, senatorial or assembly district and the other part or parts thereof were allocated to another or other congressional, senatorial or assembly districts. Such part of a split voting district so allocated to a congressional, senatorial or assembly district shall be a separate voting district and shall have its own separate enrollment list, registry list, list of unaffiliated electors if required under section 9-55, and polling place, and shall for all other administrative purposes be treated as a separate voting district. In a municipality which elects no town, city or borough officers from political subdivisions at a municipal election, this section shall apply to all elections unless and until the voting districts are changed under the provisions of section 9-169. In a municipality which elects one or more town, city or borough officers from political subdivisions at a municipal election, such municipality, for municipal elections and for town committee primaries in which the town committee members are selected from political subdivisions other than assembly or senatorial districts, may continue to use the voting districts as they existed prior to such redistricting or as they are established under section 9-169d, unless and until such voting districts are changed in accordance with the provisions of section 9-169 and, in such a municipality, except as provided in section 9-169e, this section shall apply only with respect to (1) any primary or election for representative in Congress, state senator or state representative in a congressional, senatorial or assembly district which contains a part of a split voting district, (2) any primary for town committee members in which such town committee members are elected at large or in which such a senatorial or assembly district is the political subdivision from which such town committee members are elected and (3) any primary or election for a town, city or borough office in which such a senatorial or assembly district is the political subdivision from which such municipal office is elected. This section shall not preclude any town from changing the boundaries of voting districts as provided in section 9-169 and shall not apply to any town which has changed or changes the boundaries of its voting districts pursuant to said section so as to eliminate any split voting districts.
