Connecticut Statutes § 9-212 Representative in Congress

(a) In case of a vacancy in the office of representative in Congress from any district, the Governor, except as otherwise provided by law, shall not more than ten days after the occurrence of such vacancy issue writs of election directed to the town clerks or assistant town clerks, in such district, ordering an election to be held on the sixtieth day after the issue of such writs on a day, other than a Saturday or Sunday, to fill such vacancy, provided (1) if such a vacancy occurs between the one hundred twenty-fifth day and the sixty-third day before the day of a regular state or municipal election in November of any year, the Governor shall so issue such writs on the sixtieth day before the day of such regular election, ordering an election to be held on the day of such regular election, (2) if such a vacancy occurs after the sixty-third day before the day of a regular state election but before the regular state election, the Governor shall not issue such writs and no election shall be held under this section, unless the position vacated is that of member-elect, in which case the Governor shall issue such writs and an election shall be held as provided in this section, and (3) if a primary for such office occurs pursuant to subdivision (3) of subsection (b) of section 9-450 , the Governor shall, within ten days following the filing of a candidacy for nomination by a person other than the party-endorsed candidate, issue new writs of election, in place of those first issued pursuant to this section.

(b) The Governor shall cause writs of election issued pursuant to subsection (a) of this section to be conveyed to a state marshal, who shall forthwith transmit an attested copy thereof to such clerks or assistant clerks. Such clerks or assistant clerks, on receiving such writs, shall warn elections to be held on the day appointed therein in the same manner as state elections are warned, which elections shall be organized and conducted as are state elections, and the vote shall be declared, certified, directed, deposited, returned and transmitted in the same manner as at a state election.
