Final answer:
The court will grant the motion because the judge made a process error.
Step-by-step explanation:
The result of Jeff filing a motion for a new trial is most likely that the court will grant the motion because the judge made a process error. In this case, the judge improperly prohibited Jeff from admitting evidence that would have helped to show breach of the contract. By denying Jeff the opportunity to present this evidence, the judge made a mistake that affected the outcome of the trial. As a result, the court is likely to grant the motion for a new trial to rectify the error.
