The U.S. Department of Justice wants the court to disqualify all the expert witnesses of Sam Bankman-Fried, per an Aug. 28 court filing.

According to the DOJ, SBF experts’ disclosure filings are insufficient, and their experience is misleading. The prosecutors further argued that these witnesses’ testimony may be irrelevant to the case.

The DOJ discredited the essence of calling the witnesses because there are already people with enough expert knowledge on issues such as the FTX code, or the issues on trial do not relate to what the experts will give evidence on.

“There is no need for a separate ‘expert’ witness to testify on such matters, especially in light of the fact that such testimony would duplicate the testimony of fact witnesses,” it said.

If granted, the motion will affect all seven expert witnesses introduced by SBF, including a lawyer, a law professor, a data analytics expert, a financial expert, and consultants.

The filing also noted that a proposed witness, Peter Vineland, is listed as a financial services industry expert. But there is nothing to show he has enough knowledge about the crypto industry.

Meanwhile, the SBF team is also pushing that a financial analysis expert that the prosecutor wants to call should not be allowed because of the nature of his testimony.
