Did Clark County, Nevada use a defective signature-matching computer system in the 2020 election?

In 2020, Clark County used a two-step process to verify voter signatures on mail-in ballots. The Agilis computerized scanning system reviewed signatures, accepting about 30%; additional human verification was used for the remaining 70%.

Republicans filed lawsuits challenging the county’s signature verification process, which ultimately failed in both state and federal court.

A central claim of the lawsuits was that the Agilis system had a lower sensitivity setting than desired and should have accepted even fewer than 30% of signatures. Election officials testified that Agilis tested well at the setting used and that the county’s ballot rejection rate was in line with the statewide signature rejection rate.

Judges ruled that attorneys did not present sufficient evidence to warrant intervention in the election process. Republicans appealed the state case to the Nevada Supreme Court, which unanimously rejected a hearing.
