A more thorough explanation:

Definition: Newly discovered evidence refers to evidence that was not known or available during a trial, but has been found afterwards. This evidence can be used to potentially change the outcome of a trial or appeal.

Example: A man is convicted of a crime based on witness testimony and circumstantial evidence. However, after the trial, a new witness comes forward with information that could prove the man's innocence. This new witness testimony would be considered newly discovered evidence and could potentially lead to a new trial or appeal.

Explanation: The example illustrates how newly discovered evidence can impact a trial or appeal. In this case, the new witness testimony was not available during the original trial and could potentially change the outcome of the case. It is important to note that not all newly discovered evidence will lead to a new trial or appeal, as it must meet certain legal criteria to be admissible in court.
