Mr Justice Walker allowed an appeal in part against the imposition of a sanction under CPR 3.14 which limited the claimant’s costs budget to applicable court fees only following the filing of a costs budget which failed to deal with the trial and trial preparation phases. The parties had agreed all other phases up to and including a proposed second CMC or PTR and it was proposed that subsequent directions and costs budget figures be left over to be dealt with at that point. Master Thornett did not accept the parties’ proposed course and determined that in failing to file a complete budget the claimant had failed to comply with CPR 3.13, thus invoking CPR 3.14. The consequence of Walker J’s decision on appeal was to disapply the sanction in respect of those parts of the budget which had been completed and agreed but to leave in place the CPR 3.14 sanction in respect of both the trial and trial preparation phases, thus depriving the claimant of the ability to recover any costs in relation to those phases.
