If a judge grants a directed verdict against you at trial, you don't have to file a motion for a new trial before you can appeal that decision. You can go straight to the appeals court.
Normally, if you want to challenge something that happened at trial, you have to ask the trial judge to fix it first by filing a motion for a new trial. This rule creates an exception for directed verdicts. Since the judge already made a clear ruling on the record when granting the directed verdict, there's no need to ask that same judge to reconsider before moving on to the appeals process.
This saves time and avoids an extra, often pointless step. The party who lost on the directed verdict can take their case directly to the court of appeals and argue that the trial judge was wrong to take the case away from the jury.
