Palm Beach County Judges Consider Admissibility of Intoxilyzer Machine in DUI Cases
As West Palm Beach drunk driving criminal defense attorneys, we are extremely interested in the ongoing debate throughout Florida about the use of a particular brand of breath-testing machine in DUI cases. Some of our fellow defense attorneys contend that the Intoxilyzer, a machine used by Florida law enforcement, is unreliable and should not be used, or that the machine’s manufacturer should be forced to release source code so that defense attorneys can understand how evidence against their clients is reached. Several counties have already ruled on the Intoxilyzer’s admission, and now, Palm Beach County is considering it as well. On Feb. 23, the South Florida Sun-Sentinel reported that a panel of seven criminal judges is considering whether to throw out Intoxilyzer records for nearly 500 defendants with active DUI cases.
Most interestingly, the two private attorneys and one public defender in the case say that some Palm Beach County prosecutors are intentionally turning off machines when it looks like they are going to fail inspections. Intoxilyzer machines must be inspected routinely to ensure that the evidence they produce is reliable. A Florida Department of Law Enforcement employee was fired last year for doing this in Miami-Dade County. The defense attorneys claim the fired employee had told at least four others how to do this as well, and an outside forensic expert said he found evidence that certain inspectors had a pattern of doing this. However, one police officer said he sometimes turns off machines because they “freeze.” The defense lawyers also argue that the specific model of Intoxilyzer at issue must be approved by the federal government to be used in Florida.
A ruling in favor of the defense attorneys would require prosecutors to throw out all of the cases against their nearly 500 clients. It would also invalidate the use of the Intoxilyzer in Palm Beach County, though not necessarily in neighboring counties. As Miami DUI criminal defense lawyers, we hope the judges come to a decision that is fair to DUI defendants whose test results may have been skewed by the inspectors’ malfeasance. The blood-alcohol concentration test result is essential in a drunk driving case, because it usually makes up the only direct evidence against the driver. If that test is off by even 0.01, innocent people can be criminally charged with drunk driving (and guilty people can go free). Tampering with that test result is essentially tampering with justice.
