Costs Practice Direction 10.1 states:
“In a case to which rule 44.3B(1)(c) or (d) applies the party in default may apply for relief from the sanction. He should do so as quickly as possible after he becomes aware of the default. An application, supported by evidence, should be made under Part 23 to a costs judge or district judge of the court which is dealing with the case. (Attention is drawn to rules 3.8 and 3.9 which deal with sanctions and relief from sanctions).”
Why no mention of CPR 44.3B(1)(e) concerning notification of ATE premiums? Something else for the next CPR update given this seems to have been overlooked when CPR 44.3B(1)(e) was introduced?
