A case is labeled closed when it goes to trial, and a conviction has been made. Closed cases do have the chance of being reopened to present new evidence and be reevaluated. A dismissed case can occur at the time before a trial when it is determined that a case cannot proceed; this can be due to a lack of enough evidence that a case would be impossible to succeed. To state it simply, all dismissed cases are closed, but not all closed cases are dismissed.
