Handling eDiscovery on matters that require compliance with the United States International Traffic in Arms Regulations (ITAR) can be a challenge. For those who have yet to experience working under ITAR, it comes into play when one or more parties (or a non-party) to a litigation is a US Government contractor, particularly in the national security or military/defense industry, and is responsible for the licensing, export or import of materials and services governed by the Arms Export Control Act. Law firms and discovery service providers who wish to take on ITAR matters must fulfill the regulatory demands limiting who can access this potentially sensitive information. One key component is ensuring that the companies working on the matter are incorporated to do business in the United States, and relatedly, that all staff who will have access case documents meet the definition of “U.S. person” in ITAR.
