Two members of the Wisconsin Elections Commission have moved to intervene in a lawsuit against guidance their own agency issued last month, taking the unusual step of arguing in court against a policy adopted by the body they sit on. Democratic commissioners Ann Jacobs and Mark Thomsen filed to join the case challenging new rules that bar absentee voters from spoiling a returned mail ballot and casting a new one, a practice long available to voters who show up in person on Election Day.
What the new guidance does
The Wisconsin Elections Commission voted 4-2 on July 9 to adopt guidance stating that voters who cast an absentee ballot cannot later ‘spoil’ it and receive a replacement, even if their preferred candidate withdraws from a race or the voter simply changes their mind before the ballot is counted. Jacobs and Thomsen cast the two dissenting votes at the time, arguing the policy creates an unjustified disparity between mail and in-person voters just weeks before the state’s August 2026 primary.
The legal challenge
A lawsuit filed shortly after the guidance passed argues the rule violates equal protection principles by treating absentee voters more harshly than those who vote in person, who under Wisconsin procedure can spoil a ballot twice and receive up to two replacements. The suit, filed in state court, asks a judge to block enforcement of the July 9 guidance before ballots go out for the primary. Jacobs and Thomsen’s motion to intervene aligns them procedurally with the plaintiffs rather than defending the commission’s own action, an alignment election law observers say is uncommon for sitting commissioners.
Background: a fight that predates this year
Ballot-spoiling has been the subject of litigation before. The issue first became contested in 2022 after a Republican-aligned organization sued over earlier commission guidance that permitted absentee voters to spoil and recast ballots. An appeals court eventually overturned a lower-court ruling in that case on procedural grounds related to how the lawsuit had been served, without ever deciding whether spoiling itself was lawful under Wisconsin statute. This year’s commission vote effectively reversed the prior practice, prompting the current challenge from the opposite direction.
Two sides of the argument
Republican members of the commission who supported the July guidance have argued that allowing repeated ballot changes for absentee voters creates administrative burdens and potential security risks for clerks processing high volumes of mail ballots close to an election. Democratic officials, voting-rights advocates, and the two dissenting commissioners counter that voters should not lose a right available to their in-person counterparts simply because they chose to vote by mail, especially when a candidate’s late withdrawal leaves an absentee voter no practical way to change their vote otherwise.
Stakes for the August primary
With early voting already underway in parts of the state, the timing of any court ruling matters. Clerks say they need clear guidance well before ballots are tabulated to avoid inconsistent handling across Wisconsin’s 72 counties. Voting-rights groups have warned that without a swift ruling, some absentee voters could be effectively locked into a vote for a withdrawn or otherwise changed candidate, while clerks in Republican-leaning counties have said reversing course again on short notice would create confusion of its own.
What comes next
A hearing on the intervention motion and the underlying challenge is expected in the coming weeks, with both sides pushing for a decision before the primary’s final ballot-counting deadline. Election administrators statewide are watching the case closely, given that Wisconsin’s tight statewide races have repeatedly been decided by narrow margins, and any procedural change affecting how absentee ballots are handled could carry outsized weight in close contests. The dispute is also expected to resurface in the fall general election if the underlying legal question of ballot-spoiling rights is not fully resolved before then.
An unusual internal split
Election law observers say it is rare for sitting commissioners to formally intervene against guidance their own body adopted, and the move has highlighted a deeper partisan divide on a commission designed to operate on a bipartisan basis with three Democratic and three Republican appointees. Jacobs and Thomsen argued in their filing that remaining silent while the guidance took effect would leave voters without adequate representation in court, since the commission as an institution is legally obligated to defend its own policy regardless of how individual members voted. Republican commissioners have pushed back, saying the intervention motion undermines the commission’s credibility as a neutral administrative body just as it prepares to oversee a contested primary.
