When is the appropriate time to submit a rejoinder to the WNA of the OP

Dear Client,
The request for permission to file rejoinder to WNA should be made before the day fixed for oral argument to enable the other party to go through and prepare himself or herself for oral argument. As per Regulation 13(2) of the Consumer Protection (Consumer Commission Procedure) Regulations, 2020, where a party is represented by a counsel, it shall be mandatory to file a brief of written arguments two days before the matter is fixed for arguments. As per Regulation 13(3), in case of default to file briefs of written argument, the Consumer Commission shall impose such cost as it deems necessary. So, the question of filing rejoinder on the date fixed for oral argument does not arise. However, even if it is allowed, the Commission shall fixed the oral argument on another date recording the reasons of allowing the rejoinder to the WNA and deferring the date of oral argument in the daily order sheet of the proceedings.
