This is one of the most important decisions on derivative litigation in many years. There are 3 key holdings, at least one of which may reverse prior law. First, the Court held that a derivative suit dismissed for failure to plead sufficient grounds to proceed under the demand rules may be refiled by a different plaintiff who has a better complaint. This may modify prior law that had held that once dismissed with prejudice, the suit could not be revived by a better complaint from a new plaintiff.
Probably not case book material, however.
