interlocutory appeals act
Interlocutory Appeals Act. A federal statute, enacted in 1958, that grants discretion to a U.S. court of appeals to review an interlocutory order in a civil case if the trial judge states in writing that the order involves a controlling question of law on which there is substantial ground for difference of opinion, and that an immediate appeal from the order may materially advance the termination of the litigation. 28 USCA § 1292(b). Cf. FINALITY DOCTRINE; FINAL-JUDGMENT RULE. [Cases: Federal Courts 660. 1.]
