The Department of Justice will not disclose the names of its lawyers responsible for more than 650 ethical violations found in internal agency watchdog reports.

DOJ’s Office of Professional Responsibility documented more than 650 examples of its lawyers violating department ethics rules, according to a review of internal documents and OPR reports compiled by the Project on Government Oversight.

The review, spanning fiscal year 2002 through fiscal year 2013, found more than 400 cases of recklessness or intentional misconduct, according to OPR’s own standards. The office investigated approximately 2,100 alleged abuses during this time.

DOJ upholds a practice of not disclosing the names of lawyers identified by OPR as having committed offenses.
