Police Blotter: Defendant wins breathalyzer source code

Police Blotter is a weekly News.com report on the intersection of technology and the law.

What: Drunk driving defendant says he needs the source code to the Intoxilyzer 5000EN to fight the charges in court.

When: Minnesota Supreme Court rules in his favor on July 26.

Outcome: Source code will be turned over to defense attorneys.

What happened, according to court records and other documents:
When Dale Lee Underdahl was arrested on February 18, 2006, on suspicion of drunk driving, he submitted to a breath test that was conducted using a product called the Intoxilyzer 5000EN.

During a subsequent court hearing on charges of third-degree DUI, Underdahl asked for a copy of the "complete computer source code for the (Intoxilyzer) currently in use in the state of Minnesota."

An article in the Pioneer Press quoted his attorney, Jeffrey Sheridan, as saying the source code was necessary because otherwise "for all we know, it's a random number generator." It is hardly new technology: One criminal defense attorney says the Intoxilyzer is based on the antique Z-80 microprocessor.

A judge granted the defendant's request, but Michael Campion, Minnesota's commissioner in charge of public safety, opposed it. Minnesota quickly asked an appeals court to intervene, which it declined to do. Then the state appealed a second time.

What became central to the dispute was whether the source code was owned by the state or CMI, the maker of the Intoxilyzer.

Minnesota's original bid proposal that CMI responded to says that "all right, title, and interest in all copyrightable material" that CMI creates as part of the contract "will be the property of the state." The bid proposal also says CMI must provide "information" to be used by "attorneys representing individuals charged with crimes in which a test with the proposed instrument is part of the evidence," which seems to include source code.

Campion's office, on the other hand, claims the source code is confidential, copyrighted and proprietary. It has asked for what's known as a "writ of prohibition" barring the source code from being released.

The Minnesota Supreme Court rejected the request, saying "a writ of prohibition is an extraordinary remedy and is only used in extraordinary cases."

This isn't the first time breathalyzer source code has been the subject of legal scrutiny. A Florida court ruled two years ago that police can't use electronic breathalyzers as courtroom evidence against drivers unless the source code is disclosed. Other alleged drunk drivers have had charges thrown out because CMI refuses to reveal the Intoxilyzer source code.

Excerpt from Minnesota Supreme Court's ruling:
The district court ordered the production of the "complete computer source code" for the Intoxilyzer 5000EN. In support of its order, the district court found that under the contract between the state and CMI, the state owned the source code for the Intoxilyzer 5000EN. The court of appeals concluded that the district court's finding was not clearly erroneous given the concession in the state's petition seeking the writ of prohibition that it owned that portion of the source code created exclusively for the Intoxilyzer 5000EN...

Having carefully reviewed the record presented and the arguments of the parties, we conclude that we cannot decide the copyright issues raised. Although the parties direct us to copyright law regarding works for hire and derivative works, they provide only a superficial application of that law to the facts of this case. Perhaps that is because the factual record before us is inadequate, thereby making any determination regarding either copyright theory impossible.

Resolution of this issue, however, does not require us to apply federal copyright law because we also conclude that the commissioner has failed to meet his burden of demonstrating that the information sought is clearly not discoverable and that he has no adequate remedy at law. While on the one hand the commissioner argues that ownership of the source code for the Intoxilyzer 5000EN is to be determined under federal copyright law and that under that law he does not have possession, custody or control of the source code, on the other hand he concedes that the state owns and thus controls some portion of the source code. That concession is supported by the express language of the RFP granting CMI the right to supply the Intoxilyzer 5000EN to the state.

Further, given the express language of the RFP that requires CMI to provide the state with "information to be used by attorneys representing individuals charged with crimes in which a test with the (Intoxilyzer 5000EN) is part of the evidence" when production of the information is mandated by court order "from the court with jurisdiction of the case," it is not clear to us that the commissioner is unable to comply with the district court's order. Accordingly, we cannot conclude that the district court ordered the production of information that is clearly not discoverable...

We do not agree that the commissioner lacks adequate remedies at law. As discussed above, irrespective of whether the state owns any portion of the source code, CMI agreed, in the RFP, to provide the attorneys representing individuals charged with crimes "in which a test with the (Intoxilyzer 5000EN) is part of the evidence" information necessary to comply with a court's order. We conclude that the commissioner's ability to enforce its contract with CMI constitutes an adequate legal remedy.

None of the four circumstances justifying the issuance of a writ of prohibition...are present in this case. We, therefore, hold that the court of appeals properly denied the commissioner's petition for a writ of prohibition.

Accepting reponsibility

Someday, somewhere, someone will step up and say, "Yes i was a dumbass and drove drunk, i will accept the consequences of my actions and recieve the just punishment." The federal court should make drunk driving attempted murder. How many people have died and been permanantly injured due to the people who think they can handle it.

and the people win another one

I am glad to hear that source code for detecting criminal behavior is starting to be released in a court of law. I have no respect what-so-ever for drunk driving or drunk drivers. On the other hand if there are no checks and balances for devices that can determine guilt or innocence then some innocent persons can become victims of their own tax-paid justice system. The fact that the 'breath-o-matic' is based on a z80 microprocessor is a laff at best. They might as well use my commodore 64 playing jumpman... _s

Neither Here nor There

Your comments though valid, don't really fit the topic. The issue is the source code of the machine that tests if the guy was drunk or not. By the law, he was or wasn't. The machine needs to be accurate.

chemical analysis of blaood alcohol content has been being done since before 1800. the only differences from the "antiuqe" s&w 900 that have been implemented, at increasingly high tax-payer expense are technolgies to remove operator interference. the computations are high school chemistry. at some point technology is about communication, not complication.

That Z80

Is a great chip for a lot of devices that don't need a lot of processing power. I agree, it's a good thing the source code is out. As an Engineer everthing I do right down to my calculations can be called into question in a court. Software and the professionals who right it are no different. Even if they think they are.

What's next? Radar Gun software the next time someone gets a ticket? Traffic Lights software the next time someone claims it short-cycled on them and that's why they ran it? C'mon this is a story about a drunk driver that actually got caught and is fighting for his sorry life with a defense attorney trying to make a name for himself. Determining if someone is legally drunk at the scene is not that hard to determine these days. US law should MANDATE a blood test on the spot to go along with this breathalyzer test to put an end to this issue.

This country is nuts

We the right to examine the source code on breathalizers, but the source code on voting machines, the very foundation of our democratic principles, is "proprietary" and may not be examined. Don't worry, the extreme right wing owners of the voting machine companies don't have any interest in the outcome of the elections!

But is it?
by casanavelaw August 9, 2007 1:05 PM PDT
Most states DUI/DWI laws refer to "Blood Alcohol" not "Breath Alcohol". Each person has a blood alcohol to breath alcohol ratio. The average (mean) is 1:2100. The Intoxylizer assumes that this mean ratio is everyone's ratio. In reality this is nothing more than an average. In fact the Nebraska Supreme Court recognized this back when a Commodore 64 was "cutting edge" technology. Nobody is bleeding into the intoxylizer.
