Русско-англо-русский юридический словарь

A retrial is a new trial of a case to re-examine some or all of the matters from the concluded trial. A party files a motion for a new trial, and a court may grant a retrial if there was a significant error of law, a verdict going against the weight of the evidence, irregularity in the court proceeding, jury or prosecutorial misconduct, newly discovered material evidence, or improper damages. (Legal Information Institute)

n. a request made by the loser for the case to be tried again on the basis that there were significant legal errors in the way the trial was conducted and/or the jury or the judge sitting without a jury obviously came to an incorrect result. (The People's Law Dictionary by Gerald and Kathleen Hill)
