Manatee County Judge Rules Intoxilyzer Machine Results Admissible in DUI Cases
Our Sarasota drunk driving defense attorneys were disappointed to see a recent ruling from a judge in nearby Manatee County. According to a Nov. 14 article in the Bradenton Herald, Manatee County judge Diana Moreland denied a motion to suppress the use of breath test results obtained from a machine called the Intoxilyzer 8000 in a DUI case involving 31-year-old Janet Landrum of Ellenton. The order affects every DUI case in Manatee County, not just Landrum’s, which means the order allows the use of Intoxilyzer 8000 results in more than 100 cases. The South Florida DUI defense lawyer for Landrum has also challenged the accuracy of the test results.
The ruling is the latest in a controversy over whether the Intoxilyzer 8000 and its cousin, the Inxotilyzer 5000, should be admissible in Florida. Courts around Florida have previously ruled on whether the machines are admissible, a history that includes rulings in Manatee and Sarasota Counties against using them. Under Florida law, law enforcement may use only breath test machines approved by the federal Department of Transportation. The list of DoT-approved devices does include an older version of the Intoxilyzer 8000, but the machine has seen software changes since then. This has created confusion in Florida courts, with different counties ruling different ways on whether the machines’ results are admissible at all.
Complicating matters further, some Fort Myers DUI defense attorneys have also argued that the Intoxilyzer 8000’s test results are not reliable. In some cases, they say, software problems create a false positive when the machine should really show that results are inconclusive and the driver should blow again. This has led at least one state to ban the use of the machine entirely, on the grounds that no one should be convicted because of an inaccurate reading. Intoxicated driving defense attorneys and their clients argue that they are entitled to see the source code of the software the Intoxilyzer machines use so they can determine their accuracy. But the machines’ manufacturer, CMI Inc., refuses to disclose the source code, saying it’s a trade secret. The Florida Department of Law Enforcement has an ongoing case before the courts to decide ownership of the source code.
Our Punta Gorda intoxicated driving criminal defense lawyers hope the courts eventually decide that Florida’s law enforcement community -- and the drivers it serves -- are entitled to the source code. As things currently stand, there’s nothing stopping Florida drivers from being convicted of DUI on a false positive from an Intoxilyzer machine that nobody can double-check. Ideally, we’d prefer that Intoxilyzer results be declared inadmissible throughout Florida until this question, and the question about whether the machines are authorized, are both resolved. A drunk driving charge is very serious in Florida, carrying jail time, fines, license suspension and an immediate spike in auto insurance rates, among other things. To serve justice, those accused should be entitled to be judged on test results not tainted by doubts and lack of accountability.
