Post-election reviews


Post-election Review of Voting Systems

Minnesota Statutes 206.89 states that after every state general election, Minnesota counties perform a post-election review of election results returned by the optical scan ballot counters used in the state.  The review is a hand count of the ballots for each eligible election (U.S. President, U.S. Senator, U.S. Representative, and Governor) in the selected precincts compared with the results from the voting system used in those precincts.

Selection process

At the canvass of the state primary, the county canvassing board (the board that certifies federal, state and county election results in that county) in each county must set the date, time, and place for the post-election review of the general election, and notify the Secretary of State.

At the canvass of the state general election, the county canvassing boards must randomly select the precincts to be reviewed, and notify the Secretary of State.

  • In a county with fewer than 50,000 registered voters, the county canvassing board must conduct a post-election review of a total of at least 2 precincts.
  • In a county with between 50,000 and 100,000 registered voters, the county canvassing board must conduct a review of a total of at least 3 precincts.
  • The county canvassing board of a county with more than 100,000 registered voters must conduct a review of a total of at least 4 precincts, or three percent of the total number of precincts in the county, whichever is greater.

At least one precinct selected in each county must have had more than 150 votes cast at the general election.

The county auditor must notify the Secretary of State of the precincts chosen for review, along with the time and place the review will be conducted as soon as the decisions are made.

Post-Election Performance Review

The Secretary of State must monitor and evaluate election procedures in the precincts audited in the post-election review. At least four precincts in each congressional district must be reviewed. The precincts must be chosen by lot by the State Canvassing Board at its meeting to canvass the state general election. (Minnesota Statutes 206.895)
