Expert witnesses may be required to attend First-tier Tribunal (FTT) or Upper Tribunal (UT) hearings to give oral evidence and face cross-examination. The tribunal may direct oral evidence where the expert's credibility, methodology, or specific findings are in dispute.
Oral evidence requires preparation beyond the written report: experts must review their report, letter of instruction, and all source materials; ensure consistency between written and oral testimony; and be prepared to defend methodology and source selection under questioning from the opposing party's representative.
Joint expert meetings may be directed where multiple experts are instructed. Experts should prepare a joint statement identifying areas of agreement and disagreement, reducing hearing time and focusing cross-examination on genuinely disputed issues.
