WITNESS CREDIBILITY AND LYING IN THE FAMILY COURT
 
 
R v Lucas [1981] QB 720 The 'Lucas' Direction: Lies in the family court
 
"Just because a person lies about one thing it does not automatically follow that they are lying about everything. This is the perhaps obvious rationale which has informed judges and tribunals charged with the responsibility of fact-finding hearings for many years but at least since the seminal court of appeal authority"
 
Lucas direction as would be given at a criminal trial, Source: Chapter 16-3 of the December 2020 Crown Court Compendium:

1. A defendant’s lie, whether made before the trial or in the course of evidence or both, may be Probative of guilt. A lie is only capable of supporting other evidence if first it is shown by other evidence in the case to be a deliberate untruth, that is that it did not arise from confusion or mistake; second It relates to a significant issue, and third it was not told for a reason advanced by or on behalf of the witness or for some other reason arising from the evidence, which does not point to it being a lie.

2. The direction that I give myself should be tailored to the circumstances case come up but I must direct myself that only if I'm satisfied on the balance of probabilities that the criteria are met should a lie be used as some support for the case advanced by the other party, but in any event a lie cannot by itself prove the opposite case.

 
 
Re A (A Child) (No 2) [2011 EEWCA Civ 12 at para 104
 
“A witness deposing to serious domestic violence and grave sexual abuse – whose evidence, although shot through with unreliability as to details, with gross exaggeration and even with lies, is nonetheless compelling and convincing as to the central core… Yet through all the lies, as experience teaches, one may nonetheless be left with a powerful conviction that on the essentials the witness is telling the truth, perhaps because of the way in which she gives her evidence, perhaps because of a number of small points which, although trivial in themselves, nonetheless suddenly illuminate the underlying realities.”
