This summary is not the rule. The rule text controls.
This rule number doesn't currently contain any content. It's marked as "reserved," which means the court system has set aside this number for possible future use, but no rule has been written for it yet.
If you're looking for specific guidance on a court procedure, this isn't the place to find it right now. You may want to check neighboring rule numbers in the same section, as the topic you're researching is likely covered elsewhere in the Uniform Civil Rules. If you're working on a case and expected to find something under this number, it's a good idea to double check with the court clerk or a legal professional to make sure you're looking in the right place.
