Sec. 16. Intervention of the offended party in criminal action. – Where the civil action for recovery of civil liability is instituted in the criminal action pursuant to Rule 111, the offended party may intervene by counsel in the prosecution of the offense.
What does "the offended party may intervene by counsel in the prosecution of the offense" mean? Does it have anything to do with say, when i filed a complaint against somebody and i am not the offended party, then the offended party can intervene? What happens when he intervenes?
