From Wikipedia, the free encyclopedia:
In civil procedure, 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.
This is not what you asked, but I think one might easily confuse this concept with another, as this author seems to, also from Wikipedia, the free encyclopedia:
In common law legal systems original jurisdiction of a court is the
power to hear a case for the first time, as opposed to appellate
jurisdiction, when a higher court has the power to review a lower
court's decision. Original jurisdiction refers to the right of the
Supreme court to hear a case for the first time. It has the exclusive
right to hear all cases that deal with disputes between states, or
between states and the union government. It also has original
jurisdiction over cases brought to the court by ordinary people
regarding issues to the importance of society at large.
It's puzzling that the author of the second-quoted paragraph says that the Supreme court "has the exclusive right" to hear certain cases, as the point is not about the exclusive right to hear the case but rather the right to give the legal question its first hearing as distinct from an appeal.
