Whether the District Court’s order refusing to require security under the New Jersey statute was immediately appealable as a final decision.
Holding
Yes. The order was appealable because it conclusively determined a substantial collateral right that could not effectively be reviewed after final judgment on the merits.
Reasoning
Although federal appellate jurisdiction generally extends only to final decisions, “final” has a practical rather than purely technical meaning. The order had conclusively resolved the corporation’s asserted entitlement to security; it was not tentative, unfinished, or subject to later reconsideration on that legal question.
The security issue was separate from the merits of the derivative claims. The order neither advanced nor decided whether the directors had committed fraud or mismanagement, and it would not merge into a later merits judgment in a way that would permit meaningful review.
Deferring review until the case ended would likely destroy the statutory right. If the corporation had to incur litigation expenses without the security to which it claimed entitlement, a later appeal could not restore the lost protection. The Court emphasized, however, that not every order setting a security amount is appealable; this appeal involved the serious and unsettled question whether a right to security existed at all.
