I'm asking this on behalf of a friend of mine; there's a long-running history of abuse on the part of his mother toward her husband and my friend. Some time ago (I forget exactly, but want to say between one and two years) his mother physically assaulted his father, and my friend called the police. However, his father decided not to press charges and things have gone back to "normal," in this case being just more abuse, including a recent incident which has prompted me to ask for advice.
I'm asking if the dismissed assault charge can be renewed or used in evidence for a new filing. Also, as a witness, would I be able to report abuse on behalf of my friend and his father and would they be able to dismiss the charge "out from under me?"
Also to clarify, there are no minors involved.
