Expert testimony must meet the criteria of being both relevant and reliable.

This case highlights the importance of upholding rigorous standards in admitting expert testimony. For law students, People v. King illustrates the application of the Daubert standard, underscoring the judiciary’s gatekeeper role in ensuring only scientifically valid and reliable evidence is presented to juries, thus protecting defendants’ rights to fair trials.
