The best thing to do, if your son has not already been charged with the crime is to hire an attorney who can investigate the case and perhaps persuade the police that what he is saying is true.

No, the Judge is not obligated to refer for prosecution. Judges only do this in rare case that generally involve a fraud upon the court.

That may or may not constitute a crime depending on the nature of the statement and the circumstances surrounding it.
