Conn. Gen. Stat. § 9-272: Conditions under which use of voting tabulators may be discontinued.

If, owing to the number of candidates to be voted upon, owing to inability to obtain a sufficient number of voting tabulators or, if it is found impracticable to use voting tabulators at any election, primary or referenda to be held in any municipality, or in one or more of the voting districts therein, the registrars of voters may discontinue the use of such tabulators for such election in any of the voting districts therein, and shall thereupon cause ballots to be procured and used at such election, primary or referenda in each of the voting districts wherein the use of voting tabulators has been so discontinued. The procedures for securing and counting the paper ballots described in this section shall be in compliance as nearly as possible, in the manner prescribed by the Secretary of the State, with the procedures for securing and counting absentee ballots.
