In 2010, the Judicial Conference Advisory Committee on Civil Rules requested a study of motions for sanctions based on an allegation that the nonmoving party had destroyed evidence, especially electronically stored information (ESI). The study examined the electronic docket records of civil cases filed in 2007–2008 in 19 districts, including at least one district in every circuit except the District of Columbia Circuit. This report summarizes the findings of that study and, where appropriate, compares those findings to other studies.
