U.S. District Chief Judge Margo K. Brodie of the Eastern District of New York on Friday agreed to extend the adjournment of former Goldman Sachs banker Roger Ng’s trial amid what Brooklyn federal prosecutors have described as a “total institutional failure” to turn over discovery materials to the defense.

Prosecutors first disclosed the issue late Tuesday, telling Brodie in a letter that they had just learned that a U.S. Department of Justice privilege review team had failed to disclose about 15,500 documents to Ng’s attorneys or to the prosecutors handling the trial.
