Palm Beach County hanging-chads controversy
Sequoia became associated with allegations that poor-quality punch-card ballots supplied for Palm Beach County contributed to the hanging-chad problems of the 2000 election. A later investigative report cited former employees who alleged that paper and manufacturing processes fell outside normal specifications. These claims were reported allegations rather than established findings in the cited material.
