This summary is not the rule. The rule text controls.
This rule is currently reserved, which means it has no content. Courts sometimes leave a rule number open like this to keep the numbering system consistent, or in case they need to add a new rule in this spot later.
If you're looking for specific guidance on appellate procedure, you'll need to check a different rule number. Nothing here applies to your case right now, since there's no active rule text at this location.
