Ariz. court rules software for DUI test off-limits

TUCSON, Ariz. (AP) — Defense attorneys are neither entitled to the source code for the breath-testing machine commonly used in drunk driving cases nor to its software, the Arizona Court of Appeals has ruled.

For more than a year, defense attorneys throughout Pima County have been arguing they should be given the "source code" and software used in the Intoxilyzer 8000.

On Tuesday, the appeals court ruled prosecutors don't have to hand over either the source code or the software.
