THE WHOLE TRUTH? HYPOTHETICAL QUESTIONS AND THE (DE)CONSTRUCTION OF KNOWLEDGE IN EXPERT WITNESS CROSS-EXAMINATION

Summary/Abstract: This paper examines the relation between hypotheticals and epistemic stance in jury trials, and it reveals how hypothetically framed questions (HQs) are used in cross- examination to construct “the admissible truth” (Gutheil et al. 2003) which is then turned into evidence. It looks at a selection of interactional exchanges identified in the transcripts and video recordings which document two days of expert witness cross- examination in two high-profile criminal cases. In the study, two approaches to data anal- ysis were combined: a bottom-up approach focusing on markers of HQs offering “points of entry” into discourse through a corpus-assisted analysis and a top-down approach looking at cross-examination as a complex communicative event, providing a more holis- tic view of the interactional context in which HQs are used. The paper explains the role which such questions play in the positioning of opposing knowledge claims, as well as discusses the effect they create in hostile interaction with expert witnesses. As is revealed, HQs are used to elicit the witness’s assessments of alternative scenarios of past events and causal links involving the facts of the case; to elicit the witness’s assessments of general hypothetical scenarios not involving the facts of the case, or to undermine the validity of the witness’s method of analysis. In sum, the paper explains how the use of HQs aids cross-examining attorneys in deconstructing unfavourable testimony and constructing the “legal truth” which supports their narrative.
