Newly Discovered Evidence Law and Legal Definition

In a civil or criminal case, evidence that existed at the time of a motion or trial but that could not have been discovered with reasonable diligence prior to a court ruling upon the motion or the trial's completion is called a newly discovered evidence. Upon later discovery, a losing party may assert newly discovered evidence, as grounds for a court to reconsider a motion or order a new trial. Newly discovered evidence is also called after-discovered evidence.
