An interim order that is explicitly temporary in nature, does not finally determine rights, and is aimed solely at preserving the integrity of a statutory process pending final adjudication, is not appealable under the Zweni test as it lacks the required finality and definitiveness. While the interests of justice may permit appeals of interim orders in exceptional circumstances, no such exception applies where the order is modest, time-limited, the time period has elapsed rendering the matter moot, and no exceptional prejudice, procedural injustice, conflicting judgments, or broader jurisprudential significance is demonstrated. An appeal cannot be used as a mechanism to vary an order by introducing new evidence; where a party cannot comply with an order, procedural mechanisms other than appeal must be utilized.
