According to TechFlow, the New York Times reported that SBF, the founder of the crypto trading platform FTX, has formally appealed against his fraud charges, requesting a retrial and accusing the judge who tried his case of being unfairly biased against him.

Last November, a New York jury convicted SBF of seven counts of fraud and conspiracy related to the collapse of his cryptocurrency trading platform in November 2022. In March, U.S. District Judge Lewis Kaplan of the Southern District of New York (SDNY) sentenced SBF to 25 years in prison for the crimes, of which he has already served six months.

In a 102-page appeal filed Friday afternoon, SBF’s attorneys argued that Judge Kaplan treated the FTX founder unfairly throughout the trial, making “scathing remarks that undermined the defense” and “ridiculing” his testimony in front of the jury.
