This summary is not the rule. The rule text controls.
This rule is currently marked "reserved" in the Idaho Criminal Rules. That means there is no actual content or requirement here right now. Court rule numbers are sometimes reserved like this so the numbering system can stay consistent if a new rule gets added later, or because a rule that used to be here was removed.
If you're looking for guidance on this topic, you won't find it under Rule 51. You'll need to check other nearby rules in the Idaho Criminal Rules, or look for updates in case this section gets filled in down the road. It's a good idea to check the most current version of the rules or ask a legal professional if you're trying to track down specific information, since reserved rules can sometimes be replaced with new content.
