Frederick Lyon

Frederick Lyon

  • Called in 2012

Civil Fraud

Frederick has regular experience in cases proceeding on the fast and multi tracks where fraud or fundamental dishonesty is alleged. He acts in such cases, particularly on behalf of defendants, at least weekly.

He has successfully obtained numerous findings of fundamental dishonesty on behalf of defendants both in trials and in stand-alone applications (including two in a single week). He has also had multiple claims dismissed in full on the basis of dishonesty in part of the claim under s.57.

His experience includes cases involving LVI, manufactured accidents, occupancy, exaggerated injuries, and dishonest descriptions of accident circumstances.

While he predominantly appears for defendants Frederick’s in-depth knowledge of claims, where dishonesty is alleged, make him a useful asset to claimant firms with clients facing such allegations. Frederick was recently successful in the High Court on behalf of a claimant in defending contempt of court proceedings following a finding of fundamental dishonesty in an earlier civil claim undertaken by different counsel.

Frederick has broad experience of credit hire claims in which allegations of fraudulent misrepresentation are made against agents of the credit hire organisation in order to establish that a contract is unenforceable.
