"Open government" under fire as government suppliers claim trade secrets

Facing painful accusations of drunk driving, Dale Lee Underdahl of Minnesota challenged the accuracy of the Intoxilyzer 5000EN breathalyzer used against him, and demanded to see the source code used in the device.

The claim launched debates and a lawsuit that escalated all the way to the Minnesota Supreme Court. The device’s manufacturer, CMI, Inc. of Kentucky,claimed the source code was proprietary, copyrighted and refused to comply.  To that end, CMI attempted to block the source code’s release by filing a writ of prohibition, which was denied by the Minnesota Supreme Court, who said the writ is “an extraordinary remedy and is only used in extraordinary cases.”

The State of Minnesota specifically commissioned the Intoxilyzer 5000EN model and “all right, title, and interest in all copyrightable material” created “will be the property of the state,” according to the state’s original bid proposal. Furthermore, the proposal also said CMI must provide the necessary information to “attorneys representing individuals charged with crimes in which a test with the proposed instrument is part of the evidence,” which according to CNet, “seems to include source code.”

On July 26, the Minnesota Supreme Court ruled in Underdahl’s favor, assuring the discoverability of the devices source code and affirming his right to its examination. “The problem is, the manufacturer of the thing thinks they can hold it back and not tell anybody how it works. For all we know, it's a random number generator,” said Underdahl’s attorney, Jeffrey Sheridan.

The Minnesota Department of Public Safety has expressed reluctance to forcibly acquire the source code, and according to a department spokesman, is still considering its response. The department thinks a lawsuit is unnecessary as the contract stipulates CMI’s cooperation with court orders.

The “source code defense” has been used in a number of other states with mixed success. Manufacturers, in the interest of guarding their trade secrets, have rigorously fought against court-ordered scrutiny. In one instance, judges in Florida’s Seminole County threw out hundreds of cases involving breath tests because the manufacturer would not disclose their breathalyzer's source code. However, in another instance a group of more than 150 suspects, in Florida’s Sarasota County, were granted access to the machines’ source code, with the judges citing it was “material to their theory of defense in [their] cases.”

I haven't decided anything, except that IMO the defendent's right to examine the evidence presented against him in a criminal case trumps the claim of CMI that the code is a trade secret, especially since the contract seems to clearly state they don't own any rights to the source code.

One thing I didn't include was how the certification process for these devices work: states do not certify every single release of the source code, and manufacturers will often release bug patches or other changes directly to the breathalyzers with little oversight. (Same thing with the voting machines.) It's possible this man was scanned with one running uncertified code.

If the machine's running uncertified code, and the manufacturers' testing processes are anything short of rigorous, I can see a very valid legal defense strategy in challenging the machines themselves.

As a person who uses test equipment everyday and analyzers, we have to have them sent to a lab at specific intervals and tested to insure they read correctly. We receive a report back, traceable back to NIST that proves that every piece of equipment used to test our gear and test the tester's gear is accurate. I would be shocked if they didn't have to do something similar. Even if it's the use of a certified test gas or something like that.
Anyway it would be easy to have the machine tested to prove or disprove it's accuracy without the source code.
In my opinion, they are only asking for it, not to prove his innocence, but because they know that the case can be thrown out of court if the company refuses to comply. And if so, I think that is an abuse of the system.

In which case he really needs the firmware from that exact unit.

If you know anything about software, you should know that "in use for years and years" does not prove the lack of existence of a bug. Maybe they released a software update the week before that had a bug, for example? Maybe there's a bug in the software that's been in there all the time, that only crops up in certain considitions? Who knows.

I agree with you to a certain extent, that from a practical perspective, there is probably a 1 in 10000 chance of them finding a bug that gets this guy's case thrown out. And also I recognize that the guy's attorney is also trying to get the State to jump through all these extra hoops with the hope of them making a mistake that causes the case to be dismissed. But still, the defendent has a clear right to try to prove his innocence, and he cannot be deprived of that right.

If anything, you should be faulting the State. They should have been able to anticipate these types of legal challenges, and be ready will all the requested information. If they had been better prepared, they could just quickly provide the information, the defense could examine it, and the case could quickly proceed.

You'd think they could test the actual device that was used on him to be sure it worked properly. As long as it wasn't 'patched' or something since then.

I have no problem with someone trying to prove their innocence, that's their right. I do have a problem with someone trying anything to side-step the responsibility of their actions while many taxpayer $'s are being wasted in the process.

Agreed, but taxpayer dollars were wasted mainly because the State was not in control of the information they had rights to, and which they should have anticipated needing in a case like this, especially considering that this type of defense has been used elsewhere prior.

There is no way of knowing whether your tests of the same device will produce the same result, because there could be errors in the device that are only triggered under certain conditions. Just look at the studies of the Diebold et al source code in California; they've got all kinds of problems that don't show up in test mode, or even necessarily in elections, unless one does specific things to take advantage of them. What if there's a certain sequence of buttons on the breathalyzer that cause it to boost the reading 0.05 so the cops can put troublemakers in jail even when they're not drunk?

I hate drunk drivers as much as the next guy, but it's a fair argument to question the accuracy of a device which is being used to incriminate you.

It used to be that speed radars would clock a tree at 85mph or a house at 30mph, yet these same devices were standard issue and used for evidence in traffic tickets. It was people questioning the radar's accuracy that prompted the manufacturers to hunker down and make a better product.

So, just because a device is widely used and commonly accepted doesn't exclude it from scrutiny.

On a personal note, I hope that the device stands up to the scrutiny and closes the door on this defense mechanism.
