A more thorough explanation:

The judicial-economy exception is a legal rule that allows a party to seek immediate appellate review of a nonfinal order if doing so might establish a final or nearly final disposition of the entire lawsuit. This exception is an exemption from the final-judgment rule, which states that a party may only appeal from a district court's final decision that ends the litigation on the merits.

For example, if a district court issues a ruling on a key issue in a case that would effectively end the lawsuit if it were upheld on appeal, a party may be able to use the judicial-economy exception to seek immediate review of that ruling, even if the case is not yet fully resolved. This can save time and resources for both parties and the court system.

Another example of the judicial-economy exception might arise in a case where a district court has issued a preliminary injunction that would effectively resolve the entire dispute if it were upheld on appeal. In such a case, a party might be able to use the exception to seek immediate review of the injunction, rather than waiting for the case to proceed to a final judgment.

Overall, the judicial-economy exception is a tool that can help parties and courts to streamline the litigation process and resolve disputes more efficiently.
