A quick definition of inactive case:

An inactive case is a legal proceeding that is not moving forward towards a resolution. This can happen for various reasons, such as the defendant absconding or lack of prosecution. A case at bar is a case under the immediate consideration of the court. A case of first impression is a case that presents the court with an issue of law that has not previously been decided by any controlling legal authority in that jurisdiction. A test case is a lawsuit brought to establish an important legal principle or right. It can be brought by mutual consent of the parties on agreed facts. A criminal case is an investigation or an individual suspect or convict in relation to any aspect of the criminal-justice system. A case can also refer to an argument, instance, occurrence, or situation.
