State v. Fields
In State v. Fields, 196 Ariz. 580, 2 P.3d 670 (App. 1999), the Court concluded the respondent judge had abused his discretion in granting defendants' requests to physically inspect, observe, and videotape the "personnel, equipment, and procedures used" by a crime laboratory in conducting blood alcohol testing. Id. P 1.
Specifically, even taking the defendants' allegations as true, we found they had failed to establish a "substantial need" for the inspection when they had not alleged:
that their respective blood alcohol determinations were incorrect or inaccurate;
how, or even if, the alleged laboratory deficiencies affected their test results; or
any indication as to what admissible evidence they expected to find in observing the Crime Lab's operations." Id. P 7.
