This summary is not the rule. The rule text controls.
When a money judgment from a civil case gets appealed, this rule explains how interest on that money works. If the appeals court agrees with the original decision and keeps the judgment in place, interest still keeps adding up. That interest counts from the date the Superior Court first entered the judgment, not from the date the appeal ended.
If the appeals court changes the decision or sends the case back to the Superior Court with instructions to enter a new money judgment, things work differently. In that case, the Superior Court decides how much interest should be paid once it resolves the case again. So the interest question gets settled at the same time the lower court sorts out the final judgment amount.
In short, this rule makes sure interest keeps building on money judgments during an appeal, and it makes clear which court decides the interest amount depending on how the appeal turns out.
