How vacancies are filled in Connecticut


If there is a vacancy in the Connecticut General Assembly, a special election must be conducted to fill the vacant seat. The governor must call for an election no later than 10 days after the vacancy happens. All special elections must be held no later than 46 days after a governor's declaration. If the vacancy occurs between the 125th day and the 49th day before the day of the regular election, the special election will be held on the same day as the general election. If a vacancy occurs after the 49th day before the general election but before the Wednesday following the first Monday of January of the next-succeeding year, the governor shall not call a special election unless the vacant position is that of a member-elect.[1]
