Connecticut's audit was signed into law in 2007. Both the number and type of office audited varies by election.
Not less than 10% of voting districts randomly selected publicly by the Secretary of State. In the case of a municipal election, three or 20% of races randomly selected (not public) by municipal clerks (except if Governor on ballot, the Secretary of State selects races)
Discrepancies shall be investigated by the Secretary of State at his/her discretion
No earlier than 15 days after the election, end time varies.
Yes. Except the law also specifies a date before which the audits must not start. In the Nov 06 election the certification was before the date the audits could start. Also some towns actually swear in their candidates before even the a recount must be complete.
