On February 9, 2017, the Supreme Court of Delaware summarily affirmed the Court of Chancery’s decision in In re Volcano Corp. Stockholder Litigation which had dismissed plaintiffs’ complaint on defendants’ 12(b)(6) motion to dismiss.
Plaintiffs, former stockholders of Volcano Corporation, had brought an action against defendants for breaches of fiduciary duty arising from the all-cash merger between Volcano and Philips Holding USA Inc. The parties had disputed what standard of review the Court of Chancery should apply: the Revlon test, as plaintiffs claimed, because Volcano’s stockholders received cash for their shares, or the irrebuttable business judgment rule, as defendants argued, because Volcano’s stockholders were “fully informed, uncoerced, and disinterested” when they approved the merger by tendering a majority of Volacano’s shares into a tender offer. As the Court of Chancery explained, if a business judgment rule is irrebuttable, plaintiffs could only challenge the transaction on the basis of waste. Thus, plaintiffs also argued in the alternative that if the business judgment rule did apply, it should only be a rebuttable presumption.
