Litigation Associate:
ROC 2021 Short Filing Deadline
Scenario
You receive an order from the State Courts requiring your client to file a reply within 5 days of service. The order was served at 5:30 PM on Tuesday, 6 January 2026. Under ROC 2021, service after 5:00 PM is deemed served the next day, so you first work out the deemed service date. Periods of 6 days or fewer then exclude weekends and public holidays. Use the calculator to count from that deemed service date.
