"The DoJ has taken no action at all to stop any state from using voting equipment that has been proven to violate HAVA’s requirement for accurate vote-counting." See http://www.bradblog.com/?p=5884 for proofs.
"Section 301(a)(5) of HAVA spells out the mandatory standards for error rates on voting systems. It says:
The error rate of the voting system in counting ballots (determined by taking into account only those errors which are attributable to the voting system and not attributable to an act of the voter) shall comply with the error rate standards established under section 3.2.1 of the voting systems standards issued by the Federal Election Commission which are in effect on the date of the enactment of this Act."
