Can a case be reopened after it was nolle prossed?

Nolle Prossed ("Nolo Prosequi") means not prosecuted, meaning the prosecutor declined to prosecute the case. While this means that the case CANNOT be reopened once it's closed, charges can be refiled if later there is enough evidence to proceed. If the case was nolle prossed in exchange for a pretrial offer (Pre-trial intervention, or restitution for a bad check, etc.), then once the conditions of the pre-trial offer is met within a certain period of time without any arrests, the case is closed forever.
