One word for having the right to rule on a case before anyone else

I recall that there is a word used in law to refer to the right of a certain court to take up a case before a subordinate court can.

For example, if only the Supreme Court has the right to rule on a case related to terrorism (and not any other court), we say that the Supreme Court has a ______ on cases related to terrorism.

Solution 1:

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.

Solution 2:

I think the word you are looking for is prerogative.

prerogative is a special right of the king or the courts.
