reg 3B The duty of the participants in a case
(1) Each participant, in the conduct of each case, must— (a) prepare and conduct the case in accordance with the overriding objective; (b) comply with these Rules and any directions relating to the case given by a judge advocate or the court; (c) at once inform the court and all parties of any significant failure (whether or not that participant is responsible for that failure) to take any procedural step required by these Rules or any direction. A failure is significant if it might hinder the court in furthering the overriding objective. (2) Anyone involved in any way with a case is a participant in its conduct for the purposes of this rule.
