Featured Fraud cases


Operation Balaban (2019)

nstructed as a led junior for the third defendant in an eight-handed, £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.

Regina v. FI and four others (2019)

Regina v. IA and three others (2018)

Regina v. SM and seven others (2018)

Instructed as a led junior for the third defendant in a six-week, £1 million ”binary trading” boiler room fraud.


Operation Balendore (2016)

The case concerned the running of and provision of payment services to several central London brothels, the proceeds of which were laundered through a succession of sham companies. More than £6 million was recovered from the defendants under the Proceeds of Crime Act 2002. At the time, this was one of the largest confiscation orders ever made in proceedings investigated by the Metropolitan Police.

Regina v. AD (2018)

Instructed to prosecute a recidivist paedophile for causing boys under 13 to engage in sexual activity and possessing indecent images of children. The defendant had abused his position as a Credit Union branch manager in order to groom the children of customers. A number of digital storage devices were seized from his home address, which contained more than a quarter of a million unique images of child sex abuse. Sentenced to an extended sentence of 18 years.


Regina v. CR (2017)

Instructed to prosecute a retired vicar for multiple indecent assaults on a choir boy at his parish church in Stoke Newington in the late 1970s. The complainant was in the advanced stages of motor neurone disease at the time of the trial and was completely paralysed save for the use of a single facial muscle which allowed him to communicate using a Liberator Accent Eye Gaze System. The use of that system during the trial was the first instance of its kind in England and Wales.
