This lesson is the first of two designed to familiarize you with aspects of shareholders' derivative litigation and the role played by the business judgment rule. This lesson focuses on demand upon the board of directors. In most states, shareholders are required to make demand upon the board of directors before they can proceed with a derivative suit. The board's response to that demand is reviewed under the business judgment rule. This lesson will take you through the operation of the rule at this critical stage in derivative litigation.
