The Democratic Party of Wisconsin motioned Tuesday to intervene in the lawsuit Attorney General J.B. Van Hollen filed against the Government Accountability Board last week.
According to a statement, the DPW asked Dane County Circuit Court Judge Maryann Sumi to allow them to become a party to the lawsuit.
In the lawsuit, Van Hollen claimed the GAB broke election laws put in place by the Help America Vote Act by failing to cross-check voter registrations with other databases.
The DPW said they have a direct interest in the case and a right to intervene because it concerns voters' rights.
According to Tuesday's motion, the DPW claims Van Hollen's lawsuit would disenfranchise many eligible voters, a large portion of whom would have cast votes for Democratic candidates.
In a statement, DPW Chair Joe Wineke called the Van Hollen case a baseless"" and ""hyper-partisan"" lawsuit and said the Democratic Party has no choice but to intervene.
""By being a party to the lawsuit, we will be able to protect the fundamental American right of all eligible voters to have their votes counted,"" Wineke said.
Representatives from the campaign for Democratic presidential candidate Barack Obama sent a letter on Aug. 25 to the GAB urging it to reject pressure from the Republican Party to check voter information.
