Which statement best describes the purpose of the collateral order doctrine?

• A. Allows immediate appeal of discrete rulings that resolve important rights and are effectively unreviewable later.
• B. Allows appeal of any discovery order.
• C. Requires permission from the Supreme Court for any intermediate appeal.
• D. Only applies in criminal cases.

Answer: (A)

The collateral order doctrine is a narrow exception to the rule that you must wait for a final judgment to appeal. It allows immediate appeal of certain interlocutory rulings when three things are met: the ruling conclusively determines an important right; the issue is separable from the merits of the main action; and reviewing the ruling later would be effectively impossible after final judgment. The statement matches this idea by describing immediate appeal of discrete rulings that resolve important rights and would be unreviewable later. It’s not a blanket right to appeal discovery orders, it doesn’t require Supreme Court permission for every intermediate appeal, and it applies in both civil and criminal federal cases.
