The risk-limiting audit is a procedure that provides strong statistical evidence that the election outcome is correct, or has a high probability of correcting an outcome that wouldn't match a full hand count of the ballots. The audit itself requires human beings to examine and verify more ballots in close contests and fewer ballots in contests with wider margins.
