A court order dated Friday shows that a U.S. Judge has rejected FTX founder Sam Bankman Fried’s attempt at subpoenaing law firm Fenwick & West in his criminal defense.

In a court filing in May, the founder of crypto-enterprise FTX – now facing criminal prosecution by U.S. prosecutors for the dramatic collapse while the exchange is undergoing separate bankruptcy procedures – argued that he had relied on the advice of a Silicon Valley law firm ‘on many of issues which are now at core’ of the U.S. allegations against him. Bankman-Fried gave as examples the opening of the North Dimension bank account, and the use auto-deleting of Signal messages.

Bankman-Fried wanted to compel U.S. prosecutors hand over documents that the law firm had given to the government, or if they failed to do so, seek a court’s order to subpoena Fenwick & West LLP to provide the same documents.

New York District Judge Lewis A. Kaplan denied Bankman-Fried’s request on Friday, saying that neither Fenwick & West or the FTX debtors are part of “the prosecution team”. The order also added that the government “has not obligation to produce material which is not in its possession, custody or control.”

The defendant’s proposed Subpoena would be a fishing trip and not meet the requirements of specificity, relevancy, and admissibility, as set out by precedents like the U.S. case in 1974 against former President Richard Nixon. In that case, it was decided a president could not shield himself from supplying evidence to a criminal prosecution due to executive privilege.

Reuters reported that Fenwick & West sought Gibson, Dunn & Crutcher’s legal assistance to deal with scrutiny regarding its relationship with FTX.

The criminal trial of Banker-Fried is scheduled to start later this year.
