Where a special plea has been filed, it can only be heard together with an application for summary judgment if: (1) the application for summary judgment was filed first, and (2) particulars of the special plea were delivered before the hearing of the summary judgment application (Order 14 Rule 6(4)). Where a special plea is filed but not set down for hearing within the time periods prescribed by Order 14 Rule 7 (consent within 7 days, or either party setting it down within a further 48 hours), the special plea falls away and is no longer properly before the court. The party who filed the special plea must then plead to the merits, and the special plea cannot be set down for hearing before trial. Failure to comply with these procedural requirements renders the special plea invalid and it must be struck off.
