  • Operation Cullinan 2021

    Multi-Company Boiler Room Fraud

    Mark Heywood KC leading Gregory Fishwick defended in this multi-company boiler room fraud that sold diamonds as investments. The Crown’s case was that a team of brokers including Lewis Bloor from The Only Way is Essex used false identities and pressure sales techniques to con elderly and vulnerable people from hundreds of thousands.The evidence against them included a purported confession that was excluded upon application by the Defence.  The Crown also sought to include companies either side of the Indictment period as evidence of bad character but this again was successfully resisted. The Defence managed to show that the Crown’s disclosure was fundamentally flawed.  Having read the written submissions the Crown initially dispensed with their own expert who had valued the stones and nearly worthless.  Having then considered the supplemental written submissions on disclosure the Crown had to concede that they could not continue to prosecute any and all of the Defendants. Instructed by Bark & Co.

  • Operation Balaban - Southwark 2019

    Multi-Million £ Carbon Credit Fraud

    Mark Heywood KC defended in this £7 million carbon credit fraud listed for three months.  Following extensive legal argument before the close of its case, the Crown, who relied in large part on evidence of the state of the carbon credit market at the relevant time, was forced to acknowledge that its expert fell well short of the standards required in legal proceedings and that there had been disclosure failings such that it was unfair to continue to try the defendants. This case hit the headlines after the alleged expert, Andrew Ager, was discredited leading to many other convictions to be looked into on alleged mis-selling of carbon credits.
