This summary is not the rule. The rule text controls.
This rule no longer exists. It was officially removed on August 27, 2013.
Before it was repealed, the rule likely covered situations where both sides in a case agreed to ask the court to cancel, overturn, or change a judgment. Since it has been repealed, none of its provisions are in effect anymore. If you're looking for current rules on this topic, you'll need to check the Idaho Appellate Rules as they stand today, since this section was taken out entirely and may have been replaced or reorganized elsewhere.
If you're researching an old case that referenced this rule, keep in mind it only applied before August 2013. Anything happening after that date would fall under different rules.
