Last week, the Delaware Supreme Court held 3-2 that the Court of Chancery did not err by considering post-demand evidence and anonymous sources when determining whether a stockholder demonstrated a “credible basis” to suspect wrongdoing under Section 220 of the Delaware General Corporation Law.
“The general rule is that when a stockholder seeks relief under § 220, it will be limited to evidence identified in the demand and the information available to the stockholder when the demand was made. But under exceptional circumstances, the Court of Chancery may, in the exercise of its sound discretion, consider post-demand evidence that is material to the court’s credible-basis inquiry and not prejudicial to the corporation.”
Justice Traynor, writing for the Court
