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. Courts sometimes set aside a rule number like this to keep the numbering system consistent, even if there's nothing written there yet.
If you're looking for specific guidance on this topic, you'll need to check other nearby rules in the Tennessee Rules of Criminal Procedure, since the information you need may be covered elsewhere. It's also possible that this rule was removed or replaced at some point, and the number was kept empty rather than reused for something else.
If you have questions about your case, it's a good idea to talk to a lawyer or check the most current version of the rules, since court rules can change over time.
