The Supreme Court Splits the baby in the Scottsdale Crime Lab Cases.

The highly anticipated Arizona Supreme Court opinion regarding the Scottsdale Crime Lab scandal was issued yesterday.   In a very Solomon like decision, the Court granted both sides some relief.

 

The decision contains a lot of legal nuance requiring explanation. Here is a summary and a few thoughts:

 

Admissible Is Not The Same As Reliable

 

While the Court decided the blood alcohol measurements are admissible - they did not hold they are reliable. There is a big difference.  As a matter of fact, the Court expressed its concerns with the Scottsdale Crime Lab's "shaky" evidence. 

 

The Court merely held the prosecution may present the blood alcohol measurements to a jury and argue they are reliable.  The jury will make the final decision.

 

This standard is similar to a finding there was probable cause for a person's case to proceed to trial.  However, at trial, the same evidence will now need to exceed a much higher threshold - beyond reasonable doubt.

 

What Effect Did Yesterday's Decision Have On The Lower Courts' Rulings?

 

There were two lower court rulings: (1) the trial court's ruling suppressing the evidence; and (2) the Court of Appeals ruling reversing.

 
The Arizona Supreme Court vacated the relevant portions of the Court of Appeals decision and the trial court's ruling.  It then issued a new opinion which provided additional guidance on the admissibility of scientific evidence in a jury trial.
 
The Legal Boundaries Of The Supreme Court's Decision.
 
A few years ago, Arizona adopted something called the Daubert standard for the admission of scientific evidence. This was reflected by an amendment to Rule 702 of the Arizona Rules of Evidence.
 
The Court's holding here was limited to only one of the requirements of Rule 702.  Specifically the ruling is limited to subsection (d) of Rule 702, which focuses on the reliable application of a methodology to the facts.
 
What Did Each Side Get Out Of The Supreme Court's Decision?
 
The prosecution avoids mass dismissals of cases where they claim a driver was impaired, but now they have to persuade a jury in every case that the crime lab's forensic malpractice does not matter.
 
The defense is primarily benefited in two ways: (1) the right to present all the evidence of the crime lab's malpractice is firmly established; and presumably (2) the right to obtain evidence of software malfunctions and errors from the crime laboratory also appears to be affirmed. 
 
The Court's acknowledgement that the evidence presented at the 17 day pretrial hearing was both relevant and admissible at trial, implicitly holds that the defense has a right to this evidence in discovery.  This is a significant change.
 
The majority of the evidence presented to the trial court by the defense was not provided by the prosecution.  It was obtained through the collaboration of the defense community and through requests made pursuant to Arizona's public records laws.  
 
Moreover, before the pretrial hearing, there was a court order requiring the Scottsdale Crime Lab to provide the defense with all the data produced in 2011.  They were given a significant amount of time to comply, but did not even attempt to gather the information. Instead, the prosecution appealed the order, and the Arizona Court of Appeals reversed.  
 
The prosecution convinced the appellate court that the defense was merely on a "fishing expedition."  However, in hindsight, it turns out there were some pretty big fish in the pond. We can only imagine what we would have found if the yesterday's opinion had been in place at that time.
 
The holding also appears to clear the way for the defense to present a jury with evidence of the hundreds of catastrophic software malfunctions resulting in unreliable and misleading evidence.  The jury may now discover, that for years, the lab hid this damming evidence.  They may hear of internal crime lab emails from analysts admitting to deleting "incorrect results." 
 
And yes, prior to this decision, the prosecution vigorously argued the jury should not hear this evidence.
 
Does This Decision End The Debate Over The Scottsdale Crime Lab's Forensic Malpractice Issues?
 
Nope.
 
The issues will continue to be litigated - one case at a time. However, we now have some new rules of the road that empower the defense to present their case.  
 
In Sum
 
...the decision means we can't shop for justice at Costco. While there will not be a bulk dismissal of consolidated cases, we still get to present these issues one case at a time...jury by jury. 
 
This could take a while.
