A judge will hold a hearing over whether to order Arizona election officials to count provisional ballots from voters who have changed their registration addresses at motor vehicle offices since late 2016.
Judge James Teilborg also will hear arguments Wednesday over whether to order Secretary of State Michele Reagan to inform all affected voters that their registration may be out of date.
The requests were made in a lawsuit that alleges Reagan is failing to update registration addresses when people change their addresses on their driver's licenses.
The lawsuit claims a failure to update the addresses could lead to the disenfranchisement of voters.
Reagan's lawyers say the lawsuit didn't allege harm to voters and that the proposed remedies are unlikely to resolve the issue the groups are complaining about.
