Heading: application of the abandoned frye standard.

Text: ¶ 40. Although we expressly reject the Frye standard today, it should be noted that Walker's testimony was inadmissible even under the abandoned Frye rule. As we interpreted it, Frye stood for the proposition that expert testimony would be allowed only if it was based on a principle that was generally accepted in the particular field in question. Obviously, a theory or method is not generally accepted when it is unique to a particular situation, not taught or discussed in courses or textbooks, breaks new ground, and is not used by other practitioners in that particular field. It is clear that Walker's testimony was inadmissible even under the abandoned Frye test. Therefore, even under the rule we abandon today, Walker's testimony should have been excluded.
