The Public Interest Legal Foundation (PILF) is an American conservative legal group based in Indianapolis, Indiana, which is known for suing states and local governments to purge voters from election rolls. The nonprofit was constituted in 2012. PILF asserts that "large numbers of ineligible aliens are registering to vote and casting ballots", although lists that they have displayed of such supposed voters prove to actually include American natives who are eligible voters. PILF said its lists had been based on state government lists of declared “non-citizens” removed from local voter rolls, but some U.S. citizens were wrongfully purged in the process. The group has made false claims about the extent of voter fraud in the United States, and the organization has published the information of eligible voters online, including Social Security numbers, falsely accusing them of being fraudulent voters. Activities The Public Interest Legal Foundation was established in 2012. The organization is a 501(c)(3) non-profit American corporation currently based in Indianapolis, Indiana. The group has been involved in legal cases in Texas, North Carolina, Florida, Pennsylvania, Indiana, Nevada, Virginia, Kansas, D.C., and Mississippi. The organization has filed documents in favor of a Florida law barring ex-convicts who owe fines from voting. PILF has also participated as a primary party or intervenor in the U.S. Third Circuit Court of Appeals, Eleventh Circuit Court of Appeals, and the Court of Appeals for the Federal Circuit. The organization also submits amicus curiae briefs to the U.S. Supreme Court on election-related issues. PILF has sent mailings to hundreds of counties claiming that their voting rolls are provably corrupt; Politifact has judged these claims to be "false", stating that "inactive" registrants should not be counted with "active" ones when calculating total rates of voter registration. The foundation originally flagged jurisdictions with more registered voters than resident adults, according to annual U.S. Census population estimates at the time. ProPublica found major counting errors in PlLF's use of government data; PlLF subsequently corrected its analysis. In 2016 and 2017, the organization published the information of eligible voters online, including Social Security numbers, falsely accusing them of being fraudulent voters. One such voter was a U.S. missionary in Guatemala who, based on PILF's report, was inaccurately highlighted as a fraudulent voter in a Washington Times article. In 2018, the Richmond Council for the League of United Latin American Citizens and four individual voters filed a federal lawsuit, LULAC
