## Rule excerpts
Expert testimony: after counsel agreed the challenge concerned reliability under Sargon, rather than novelty under Kelly.
> Nonetheless, Avon has waived any claim that the trial court should have undertaken a strict Kelly analysis and required proof that Longo’s method was “generally accepted” in the scientific community. Put differently, Avon has waived any claim that Longo’s method was novel and required a Kelly analysis.
