WILMINGTON, Del. - A Delaware vice chancellor granted the directors and officers of a public limited partnership's motion to dismiss a shareholder's derivative complaint on Sept. 30 because the shareholder failed to show that presuit demand upon the board of directors of the limited partnership's general partner would have been futile (Frederick H. DiRienzo v. Warren G. Lichtenstein, et al., No. 7094-VCP, Del. Chanc.; 2013 Del. Ch. LEXIS 242).
