This summary is not the rule. The rule text controls.
Here's a plain-English summary:
The Nevada Supreme Court has the power to set aside its own appeal rules if needed in a specific case. This can happen because the court decides to do it on its own, or because one of the parties involved asks for it through a motion.
The court might do this to speed up a decision or for any other good reason. When it suspends a rule, the court gets to decide how the case will move forward instead of following the normal steps laid out in the rules.
There is one limit to this power. The court cannot suspend the rule found in Rule 26(b). That rule stays in place no matter what.
This rule basically gives the court flexibility. If following the standard process would cause unfair delays or problems in a particular case, the court can adjust things to make sure the case moves forward fairly and efficiently.
