This summary is not the rule. The rule text controls.
Sometimes, even after a case has been appealed, the trial court still needs to make decisions that affect how the appeal moves forward. This rule explains what happens if someone disagrees with one of those decisions.
If the trial court makes a ruling that affects your appeal, you have 14 days from the date of that ruling to ask the appeals court to look at it. You do this by filing a motion. The appeals court can then review what the trial court decided and can order a fix if needed.
This rule covers things like whether the case can even be appealed, problems with the written transcript from the trial, who has to pay for parts of the transcript, and whether someone qualifies for a free transcript or a court-appointed lawyer. It also covers money-related issues during the appeal, like bonds or payments needed to pause a court order (called a stay) while the appeal is going on.
The main point is this: you don't have to wait until the whole appeal is finished to challenge a trial court decision that affects your case right now. You can ask the appeals court to step in quickly, but you have to act fast, within 14 days.
