When you win a money judgment in a civil case and the other side appeals, this rule explains how interest on that money works. If the higher court agrees with the original judgment and keeps it in place, you still get interest going all the way back to the date the circuit court first entered the judgment. This means the person who owes the money doesn't get a break on interest just because they filed an appeal.
If the higher court changes the judgment or overturns it and sends the case back with instructions to enter a new money judgment, the court's official order (called a mandate) will spell out how interest should be handled in that situation. This gives the circuit court clear directions so there's no confusion about when interest starts or how much is owed.
In short, this rule makes sure that interest keeps accruing fairly, whether a case is upheld or sent back for changes. It protects the person owed money from losing out on interest simply because the case took longer to resolve through appeal.
