This summary is not the rule. The rule text controls.
When someone asks a higher court to step in and review a lower court's decision early (called a writ application), the appeals court has several options for how to handle it. The court can decide right away, either granting or denying the request, without waiting to hear from the other side. This can happen quickly if the situation calls for fast action.
The court also has other choices. It can ask the other side to respond before making a decision. It can ask the trial court judge to explain the reasoning behind the original ruling. Or the court can schedule the case for a hearing where both sides argue their positions, picking whatever date works for the court's calendar.
Basically, this rule gives the appeals court flexibility. It doesn't have to follow one set process for every case. Depending on how urgent or complicated the issue is, the court can move fast or take more time to gather information before deciding.
