11.3 Admissibility and Inadmissibility of Expert Opinion

The admissibility's conditions: the expert's qualification; the subject's scientific nature (the special-knowledge requirement); the facts'-basis (the examination's foundation); the relevance (the Probative Law's general test). The reliability's standards (the international line): the Daubert-and-Frye debates (the general-acceptance vs the scientific-validity — the gatekeeping judge's faces). The inadmissibility's faces: the unqualified's opinions; the common-knowledge matters (the expert unnecessary); the ultimate-issue's traditional bar (the modern erosion — the expert's opinion on the very question the court decides); the unreliable methods (the junk- science's exclusion); the hearsay's bases (the report's underlying facts). The Nepal practice: the courts' reception of the lab reports-and-testimony (the DNA-and-medical cases' line); the report-vs- examination questions (the expert's examination in the serious cases). The prescribed case6674) — the expert-opinion era's case (the court's treatment of the scientific evidence's weight-and-admissibility — read the report for the precise holding).
