A federal judge considering whether to unseal documents from a 14-year-old criminal case on Tuesday barred the public from a hearing where prosecutors apparently argued to keep some records secret and possibly to seal others that are already in the public domain.

Eastern District Judge I. Leo Glasser (See Profile) closed the courtroom to everyone other than representatives of the U.S. attorney’s office, including two lawyers who are seeking to open the files and who contend the records in play include documents they wrote and which have already been publicly disseminated. Among those records, the attorneys say, are documents discussing topics as mundane as 14th- and 15th-century judicial impeachments.
