An Ohio judge on Wednesday night restored thousands of voters’ rights, in a decision praised as a victory—”albeit a partial one”—for the scores that had been illegally purged from the state’s rolls. 

In his 22-page decision (pdf), Judge George C. Smith of the U.S. District Court in Columbus “acknowledged that his attempt to remedy what he said was Secretary of State Jon Husted’s illegal purging…will leave some eligible voters on the sidelines,” the Columbus Dispatch reported.

Husted’s purge of the voter rolls in a crucial swing state was said to be the most aggressive in the nation, impacting tens of thousands of voters over a five-year period. As The Nation‘s Ari Berman explained in September: “The purge works like this: If a voter misses an election, Ohio sends them a letter making sure their address is still current. If the voter doesn’t respond, Ohio puts them on an inactive list, and if the voter doesn’t vote in the next two elections they are removed from the rolls.”

By some estimates, this process resulted in more than two million voters being removed from state rolls since 2011—and 1.2 million of those were dubbed “questionable” by state representative Kathleen Clyde, an Ohio Democrat who led opposition to the purge. A Reuters investigation in June showed that “neighborhoods that have a high proportion of poor, African-American residents” were “hit hardest” by the practice.

Now, thanks to Wednesday’s ruling, unregistered Ohio voters who have been removed from the rolls will be allowed to cast a provisional ballot in the 2016 election.
