A more thorough explanation:

Definition: Refresh one's recollection refers to the process of reminding oneself of past events or details that may have been forgotten or become unclear over time. This can be done through reviewing documents, photographs, or other evidence, or by speaking with others who were present during the event in question.

Example: During a trial, a witness may be asked to refresh their recollection of a particular event by reviewing a police report or other document that they had previously seen. This can help the witness to provide more accurate and detailed testimony.

Explanation: The example illustrates how refreshing one's recollection can be used in a legal context to help a witness provide more accurate testimony. By reviewing a document or other evidence, the witness can jog their memory and recall details that they may have forgotten or become unclear on over time. This can be especially important in cases where the testimony of a witness is crucial to the outcome of the trial.
