“ 89. It is not necessary for us to describe the history of this debate. The outcome, in our view, is that in this tribunal, and in the FTT, the factors identified by the courts in the revised form ofCPR r 3.9 as having particular weight or importance, that is to say the need for litigation to be conducted efficiently and at proportionate cost and to enforce compliance with rules, practice directions and orders, are relevant factors, but have no special weight or importance. The weight or significance to be afforded to those factors, along with all other relevant factors, in applying the overriding objective to deal with cases fairly and justly, will be a matter for the tribunal in the particular circumstances of a given case.”
