Updates voter rolls and challenge rules. Deceased voters may be removed only after verification. Inactive voters are canceled only for death, verified out-of-state registration or a signed request, and cannot be challenged. Challenges need personal knowledge and a hand-signed affidavit; weak claims can be dismissed; hearings need probable cause; proof standard is beyond a reasonable doubt. False or baseless challenges bring penalties. Voters can fix addresses; ballots count for eligible races.
