The Minnesota Supreme Court ruled late last month that source code for the Intoxilyzer 5000EN, made by a Kentucky-based company called CMI, must be handed to defense attorneys for use in a case involving charges of third-degree DUI against a man named Dale Lee Underdahl.

In this case, the high court concluded that language in the contract between CMI and the state indicates the source code belongs by extension to Minnesota, rejecting the state public safety commissioner's earlier argument that the state was not entitled to the code because of its confidential, copyrighted and proprietary nature. The decision effectively means it's now up to the state to do what it takes to enforce that contract--including suing the company, if necessary.

But as for when the code would be turned over, "I guess the answer is probably never," attorney Jeffrey Sheridan said in a telephone interview Friday. That's because state officials, he added, "haven't given me any indication that the manufacturer has changed its mind."

It remains unclear what steps Minnesota officials plan to take, as representatives did not immediately respond to requests for comment. CMI also did not return calls for comment on Friday.
