After a months-long review of the use of corporate monitors in deferred prosecution agreements, the Justice Department on Monday announced guidelines to standardize the process.

A memo dated March 7 — and written by Craig Morford, then acting deputy attorney general — requires prosecutors to consult with U.S. Attorneys, the Criminal Division and the Office of the Deputy Attorney General before any private monitors are selected. “United States attorneys and assistant attorneys general may not make, accept or veto the selection of monitor candidates unilaterally,” the guidelines state.
