A Colorado non-profit filed a lawsuit on Monday seeking to void the result of last month’s special election in Georgia, won by Republican candidate Karen Handel against Democratic candidate Jon Ossoff in the most expensive congressional race in history.

The lawsuit, filed in Fulton County Superior Court by the Colorado-based Coalition for Good Governance (CGG) and a number of their members from Georgia, alleges that Georgia’s touchscreen voting system had severe security faults and that election officials repeatedly ignored warnings that it was compromised.

Named defendants include Georgia Secretary of State Brian Kemp, members of the State Election Board, election officials in Fulton, Cobb, and DeKalb counties and Kennesaw State University’s Center for Election Systems.

“We aren’t questioning one candidate over another,” lead plaintiff Donna Curling told Colorado Politics. “We’re saying it’s impossible to know.”

“We are in a completely different environment of cybersecurity threats than when this equipment was purchased 15 years ago,” said Marilyn Marks, executive director of the Coalition for Good Governance.

Meanwhile, in a column for USA Today on Sunday, Georgia Secretary of State Brian Kemp dismissed allegations over the integrity of their electoral system, adding that the mainstream media had developed “false narratives about Russian hacking and potential vulnerabilities in the system.”

“The prevailing plot line is that states like Georgia can’t provide suitable security for elections,” he continued. “Anything to the contrary is fake news.”

In June, a judge dismissed a similar lawsuit demanding that paper ballots be used in the special election, on the basis that early voting had already started.

The final result, in which Handel defeated Ossoff by 3.6 percentage points, proved another serious setback for the Democratic Party, who spent a record $22.5 million on the race.
