I think the question is has this type of situation ever been used to successfully reverse a previous case’s outcome? Does any case impact like that depend solely on the judge themselves admitting they were wrong and dismissing it or not, at their sole and complete discretion? Or would other ? Appeal courts have to WANT to get involved?
It happens all the time in civil lawsuits.
Even if the original verdict in favor of the plaintiff is allowed to stand, the damages are often reduced on appeal -- sometimes all the way down to $1.
