The Delaware Supreme Court recently ruled on a significant class action case involving IsZo Capital LP and Emisphere Technologies, Inc. The court's decision, issued on September 14, 2026, affects shareholders involved in class action lawsuits, particularly regarding their rights to opt out of settlements. The ruling clarifies the standards for class action certifications and the rights of shareholders in similar disputes.
IsZo Capital LP, a New York-based hedge fund, invested heavily in Emisphere Technologies, a pharmaceutical company known for its drug-delivery technology. IsZo was the largest unaffiliated stockholder of Emisphere, holding approximately 60% of its long equity positions. The dispute arose when Emisphere entered acquisition talks with Novo Nordisk A/S, which eventually led to a $1.8 billion acquisition deal. IsZo, along with other shareholders, challenged the fairness of this merger, alleging breach-of-fiduciary-duty claims against Emisphere's directors and its controlling stockholder, MHR Fund Management LLC.
The case reached the Delaware Supreme Court after IsZo objected to a class action settlement that did not allow it to opt out and pursue its own claims. The Court of Chancery had previously approved the settlement of $32 million without granting IsZo the opt-out rights it sought. IsZo argued that the lack of an opt-out option violated its due process rights and that the court had erred in its decision.
The Supreme Court's ruling affirmed the lower court's decision, stating that the Court of Chancery did not abuse its discretion in denying IsZo's request for an opt-out. The court emphasized that IsZo had received adequate representation and that the circumstances of the case did not warrant granting an opt-out right. The court noted, "the record supports its decision. We therefore conclude that there was no abuse of discretion." This ruling was delivered by Chief Justice Collins J. Seitz Jr., along with Justices Gary F. Traynor and Karen L. Valihura.
The court's opinion highlighted that while IsZo claimed the absence of an opt-out right violated its due process, the court found that IsZo had been given a fair opportunity to present its objections and that the class action met the necessary legal standards for certification. The court pointed out that IsZo did not contest the certification under Rule 23(a) and Rule 23(b)(1), which governs class actions. Instead, IsZo focused its arguments on the court's certification under Rule 23(b)(2).
The ruling has significant implications for future class action lawsuits. It reinforces the idea that courts can deny opt-out rights in certain class action contexts, particularly when the class members' interests are sufficiently aligned and when the class action is deemed to be the most efficient way to resolve the dispute. This decision may influence how future class actions are structured and the rights afforded to shareholders in similar situations.
Looking ahead, IsZo may consider appealing the decision, although it is unclear if there are any related cases pending that could further challenge the standards set by this ruling. The Delaware Supreme Court's decision serves as a reminder of the complexities involved in class action lawsuits and the importance of understanding the rights of shareholders within these frameworks.
