A more thorough explanation:

Definition: A preclusion order is a written direction or command delivered by a court or judge that bars a litigant from presenting or opposing certain claims or defenses for failing to comply with a discovery order.

Example: If a party fails to provide requested documents during the discovery phase of a lawsuit, the court may issue a preclusion order preventing that party from using those documents as evidence in the trial.

This example illustrates how a preclusion order can limit a party's ability to present certain evidence in court if they fail to comply with the court's discovery orders.
