Summary
Background
A trial court admitted testimony from a person presented as an expert in blood-spatter analysis over an objector’s protest. The case reached the Court of Military Appeals, which upheld that the testimony was admissible under Military Rule of Evidence 702, a rule the opinion says is worded the same as the Federal Rule of Evidence 702. That military court concluded the 1975 Federal Rules of Evidence superseded the older Frye test.
Reasoning
The central issue is whether the older Frye test or the Federal Rule 702 controls when courts decide if a technical expert may testify. The Supreme Court declined to review the military court’s decision, so it did not resolve that question. The dissenting opinion notes a split in lower courts: some courts treat Rule 702 as a more flexible standard (citing Downing), while others read the rule as incorporating Frye (citing Barrel of Fun and McBride).
Real world impact
By refusing to take the case, the Supreme Court left the military court’s allowance of the blood-spatter testimony in place for this case and left different lower courts using different standards. That means outcomes in future trials about scientific or technical experts may vary depending on which court hears the case.
Dissents or concurrances
Justice White, joined by Justice Brennan, dissented from the denial and would have granted review to resolve the recurring and important conflict about how to admit expert evidence.
