Example: The Supreme Court of the United States may hold an en banc sitting to review a case that is of significant importance or controversy.

Explanation: In an en banc sitting, all the judges of a court, or a quorum (a minimum number of judges required for a decision to be valid), participate in the hearing of a case. This is usually done in cases that are of significant importance or controversy, as it allows for a broader range of perspectives and opinions to be considered in the decision-making process.

Other examples of court sessions include:

• Sitting: A court session, especially a session of an appellate court.
