We reported recently on U.S. ex rel. Barko v. Halliburton Co. (D.D.C. Mar. 6, 2014), in which the court ordered the defendant to divulge internal investigation materials, despite that they were prepared at the direction and supervision of counsel, initiated in response to employee complaints of contracting fraud, and kept under lock and key in a legal department file cabinet. In "How To Protect Internal Investigation Materials From Disclosure," a Feature Comment published in BNA's The Government Contractor, C&M's Andy Liu, Gail Zirkelbach, and Jonathan Cone discuss ways in which companies can better protect their internal investigation materials from compelled disclosure.
