Griffiths v. TUI UK Limited: Evidence, Challenge and Fairness – UK Human Rights Blog

‘The central question facing the Supreme Court in Griffiths v TUI UK Limited [2023] UKSC 48 concerned the extent to which a party must put criticisms of a witness’ evidence to him in cross-examination. The Supreme Court made clear that the general rule in civil cases is that a party is required to challenge by cross-examination the evidence of any witness (whether factual or expert) if he wishes to submit that the evidence should not be accepted by the court. Importantly, this rule is not confined to allegations that the witness is dishonest. The rule is, however, a flexible one; it will not always be necessary for every point of challenge to be put to a witness, and in some cases (such as where evidence is “manifestly incredible”) it may not apply at all.
