Transcripts of secret grand jury testimony in the Ghislaine Maxwell sex trafficking case won’t be released, a judge decided Monday.

Judge Paul A. Engelmayer said in a written ruling that the government had suggested that the materials could be released publicly “casually or promiscuously,” which would risk “unraveling the foundations of secrecy upon which the grand jury is premised” and eroding confidence by persons called to testify before future grand juries.

“And it is no answer to argue that releasing the grand jury materials, because they are redundant of the evidence at Maxwell’s trial, would be innocuous. The same could be said for almost any grand jury testimony, by summary witnesses or others, given in support of charges that later proceeded to trial,” he added.
