FILE - I Voted Sticker

A lawsuit over who will be removed from voter rolls across the state of Wisconsin could be growing.

The League of Women voters on Monday asked a judge in Ozaukee County to join the case.

“Maintaining accurate voter rolls is an important part of our elections, but it must be based on accurate information,” Erin Grunze, executive director of the League of Women Voters said. “Current methods put thousands of legitimate voter registrations at risk, and a purge right now would amount to voter suppression.”

The question before the court is when the state can remove someone from the voting system.

Current law says the state must remove people within 30 days after a move.

But the League says there must be "reliable information" that someone has changed their address.

"The first time Wisconsin used this flawed data to purge voter rolls was in the 2017-2018 election cycle," the League wrote in a statement on Monday. "As a result, three cities, including Milwaukee, reversed the purge entirely because so many errors were present in the data. New letters were sent to 234,000 registered voters in October 2019."

The Wisconsin Institute for Law and Liberty filed its own lawsuit challenging those letters and the state's process.

WILL says Wisconsin must clean up its voter rolls in order to make sure that only people who are eligible to vote do so. 

WILL noted that on June 11, 2019 the Wisconsin Election Commission decided, contrary to state law, that changes in eligibility for a voter flagged as a “mover” by ERIC will not occur for 12 to 24 months.

"State agencies comprised of political appointees and un-elected staff do not have the authority to invent or amend policy contrary to state law," WILL President and General Counsel Rick Esenberg said. "Whatever the intent of the Wisconsin Election Commission’s action, it is illegal and must be remedied immediately.”

There are questions about the impact of purging voters who may have not moved, namely if any of those purged voters were not allowed to vote. Wisconsin allows voters to register and vote on Election Day, provided they have proof of residency and a photo ID.
