Anomalous-Jurisdiction Rule Law and Legal Definition

Anomalous jurisdiction rule is a principle governing the appealability of orders denying intervention. According to this rule, a court of appeals has only provisional jurisdiction to review the denial of a motion to intervene in a case, and if the court of appeals finds that the denial was correct, then its jurisdiction disappears because the proper denial of leave to intervene is not a final decision. The appeal should therefore be dismissed for want of jurisdiction. This rule has been criticized by courts and commentators. This is also known as anomalous rule.
