FOX 13 Breath Tests on Trial

Judges toss out DUI test results

In this latest challenge, prosecutors could not convince judges that the Intoxilyzer 8000 measures alcohol in the breath at exactly the same wavelength in the infrared spectrum that the manufacturer says it does.

Without that, prosecutors cannot prove the machine is the same one approved for use in Florida, the judges ruled. And state law only requires drivers to submit to breath tests using an approved machine.

“These are the rules they need to follow to make sure they have a reliable machine,” said Venice defense attorney Robert Harrison, who has led the fight against the Intoxilyzer 8000s. “They can’t just pick any machine.” https://www.heraldtribune.com/article/20090623/ARTICLE/906231040

Breath test software challenges see mixed results

In Florida, hundreds of DUI cases that had been on hold for years are finally moving towards trial after an appellate court held that the manufacturer must turn over the source code for the Intoxilyzer 5000.

“If a computer program says my client committed a crime, then I am entitled to know how [the computer program] works, especially if the software is showing a lot of bugs,” said Robert N. Harrison, a sole practitioner in Venice, Fla. who is the lead attorney in those cases.
