League of Women Voters filed a motion to intervene in support
of defendants in Public Interest Legal Foundation v. David Voye, et al, which seeks to force a purge of 14,000 voters from the rolls in Allegheny County, Pennsylvania, home to Pittsburgh, the state's second-largest city. The proposed purge is based on unverified data that these voters are deceased.  "The League and its partner organizations work tirelessly to register voters each election
cycle, and this lawsuit unreasonably creates unnecessary barriers to our work,” said Terrie Griffin, co-president of League of Women Voters of Pennsylvania. “We all want to make sure list maintenance practices are done well, and they also have to be done reasonably within the law.”  The case was filed today in Pittsburgh, but similar cases have been filed across the country.  "Pittsburgh is the second most populous city in the state, and the League works in coalition to register as many voters as possible,” said Maureen Mamula, president of League of Women Voters of Greater Pittsburgh. “Our work is directly impacted by this case, and we are respectfully asking the court to allow intervention since all three organizations present a unique view that could be valuable in resolving this important issue in time for 2020 elections.”  The League of Women Voters is represented by ACLU and Demos in this case.  “It is routine and required by law that counties regularly purge their voter registration lists of inactive voters and people who are deceased,” said Reggie Shuford, executive director of the ACLU of Pennsylvania. “We will not stand by, however, and allow outside actors to strong arm the county into excessive purging that leads to the disenfranchisement of eligible voters. Our clients have every reason to defend the interests of their members and voters, and we hope the court recognizes that.”
