This summary is not the rule. The rule text controls.
This section of the rules doesn't currently contain any content. It's labeled "reserved," which means the court has set aside this rule number for possible future use but hasn't written any actual rule here yet.
If you're looking for specific guidance on appellate procedure, you'll need to check a different rule number, since this one has nothing to apply to your case right now. Courts sometimes reserve numbers like this when they reorganize their rules or leave room for topics they might address later.
