State Summary First passed in 1986, Indiana's audit law, while it audits the entire ballot, does not lead to a full recount. Audits in Indiana are not automatic but must be requested by the county chairman of a political party.
Additionally, Indiana established a statewide "Voting System Technical Oversight Program" (VSTOP) in 2005, under Indiana Code 3-11-16: http://www.in.gov/legislative/ic/code/title3/ar11/ch16.html. VSTOP, which is currently conducted by the Bowen Center for Public Affairs at Ball State University, is charged with conducting annual random audits and preparing “reports indicating whether the voting systems have been certified, programmed, and used in compliance with Indiana law.” The manner of the audits, however, is not further detailed in the statute.

For precincts using optically-scanned paper ballots only, no more than 5% of precincts, or 5 precincts, whichever is greater, may be audited.
