Definition from Nolo’s Plain-English Law Dictionary
A court order allowing a motion or other legal matter to be set at a time shorter than provided by law or court rules. Shortening time is usually granted when the time for trial or some other court action is approaching and a hearing must be heard promptly by the judge. Example: Local rules require that a party give the other side ten days' notice before a hearing. If the trial is set to begin in nine days, a court might shorten the time to schedule a hearing to five days, provided the notice is served within 24 hours.
