intervening en banc

"Intervening en banc" refers to a legal situation where a party, not originally part of an appellate case, requests to join an appeal called "en banc," meaning before all the judges of a court (rather than a smaller panel). This typically occurs in significant cases affecting legal principles or public interests. The intervening party seeks to present their position or evidence before the full court, aiming to influence the outcome. The decision to allow intervention depends on whether their participation would help clarify important issues or impact the case's result.
