This summary is not the rule. The rule text controls.
This rule is currently reserved, which means it doesn't contain any content right now. Court rule systems often number their rules in advance, even before all the content is written. This leaves room for future rules to be added without having to renumber everything else that comes after it.
If you're looking for specific guidance on Indiana appellate procedure, this rule number won't have any information for you.
