Breath-Test Ruling Jeopardizes Thousands of State DWI Cases

 

Minneapolis, MN.  May 1 –Minnesota may be forced to drop thousands of driving-while-impaired cases and change the way it prosecutes others in the wake of a state Supreme Court ruling Thursday, prosecutors and defense attorneys agreed.

The state’s highest court ruled that defendants in drunken-driving cases have the right to make prosecutors turn over the computer “source code” that runs the Intoxilyzer breath-testing device to determine whether the device’s results are reliable.

But there’s a problem: Prosecutors can’t turn over the code because they don’t have it.

The Kentucky company that makes the Intoxilyzer says the code is a trade secret and has refused to release it, thus complicating DWI prosecutions…

The Intoxilyzer 5000EN is the standard device used by Minnesota police to determine if a driver is impaired. The state bought 260 of the machines from the manufacturer, CMI of Kentucky, in 1997, and state law presumes the devices’ results to be reliable.

The device is used with nearly eight of every 10 suspected drunken drivers who are tested in Minnesota.

But defense attorneys have argued that if they can’t examine the source code, the computer program that runs the machine, they have no way to tell if the Intoxilyzer is reliable. District judges across Minnesota have handled defense requests for the source code with a patchwork of rulings: Some say a defendant has a right to examine it; others say it isn’t relevant…

The Supreme Court said (defendant Brunner’s evidence) “show that an analysis of the source code may reveal deficiencies that could challenge the reliability of the Intoxilyzer and, in turn, would relate to Brunner’s guilt or innocence.”
