Missing: Key Documents About Alleged Misconduct By Robert Mueller’s Lead Prosecutor

Late Friday, a federal judge’s office confirmed that several documents that would shed light on the special counsel’s lead prosecutor’s alleged misconduct are missing from the court record.

...
In a joint motion to dismiss the criminal charges filed against them, four individuals connected to the Enron collapse alleged that Weissmann had improperly threatened witnesses to keep them from speaking with defense lawyers. In support of their motion, the defendants included an email Weissmann had sent to the lawyer of a “critical witness.” What exactly Weissmann said, though, is unclear, as the brief redacted the details.

Even if cause originally existed to keep the content of this email secret, with the underlying criminal cases now complete, there is no longer a basis to hide the details from the public. Thus, my motion to unredact the public record asked Judge Lake, who had presided over the criminal cases, to release unredacted copies of several court filings, most significantly the joint motion to dismiss, which included this email and other relevant details.

Over the holidays, though, the court entered an “amended notice,” announcing that after “a full and exhaustive” search by the clerk, certain court filings “were unrecoverable in their original or un-redacted form,” including the unredacted copy of the joint motion to dismiss and the supporting memorandum. Also missing from the court record was the government’s unredacted response to this motion, which likely would have included the full text—or relevant portions—of the Weissmann email.

Additionally, in the amended notice the court stated that it could not find in the case records the unredacted copy of the declaration made by Michael Tigar, an expert witness who averred that in his 40 years of experience trying criminal cases in state and federal courts, he had never seen such “unfair pressures brought to bear on the adversary system in a single case.” Several of Tigar’s other conclusions, however, were hidden behind redactions.

The missing documents probably are not something Weissmann would want to be released.  However, they probably still should exist in the governments own files and should be produced.  They could be an important indicator of the character of his prosecution style and could raise questions about his role in the Mueller investigation.
