As the end of the year draws near, there is no better time to examine the highlights of ediscovery case law from the previous twelve months. This year precipitated a new generation of ediscovery opinions, with judges delving into the intricacies of proportionality burdens and benefits, considering technology assisted review (TAR) methodologies, and weighing sanctions for preservation calamities. Choosing "the best" from a robust body of case law is far from an exact science, especially with hundreds of worthy candidates. These notable opinions in the pages that follow, along with dozens more, will set the stage for another profound year in the area of e-discovery law and practice.
