The trial court barred a defence witness with fifteen years in computer network security from testifying specifically about the disputed Google Map files, because he lacked training and experience as a forensic computer analyst, and permitted only general testimony. The Court of Appeals held that this qualification ruling was an abuse of discretion and reversed.

The court’s reasoning
The State's case rested on forensic computer analysts from a law-enforcement computer analysis response team, who opined that the recovered Google Map artifacts showed a search run from the defendant's laptop. The trial court's narrowing of the defence witness's permitted scope turned on his lack of forensic-analyst credentials rather than on the substance of his network-security expertise, and the exclusion was reviewed for abuse of discretion.
From the opinion
“the trial court's ruling that . . . Ward was not qualified to give expert testimony about tampering on [Defendant's] computer was an abuse of discretion”
Grounds argued
This ruling turned on 2 of the eight arguments that recur across the docket. Each is defined the same way on every entry, so the same ground can be followed across rulings that reached opposite results.
- Qualifications
- Whether this witness — by training, certification, or documented casework — is competent to give this opinion. Courts routinely admit examiners qualified by experience alone, and routinely narrow them when the opinion strays past the experience they described.
- Fit to the issue
- Whether the opinion helps decide a fact actually in issue. Testimony can be entirely reliable and still be excluded because it answers a question the case does not ask.
