What is the difference between executive jurisdiction and concurrent jurisdiction

exclusive jurisdiction exists where one court has the power to adjudicate a case to the exclusion of all other courts. It is the opposite situation from concurrent jurisdiction (or non exclusive jurisdiction), in which more than one court may take jurisdiction over the case.
