“ 56. … the Rules (which govern our procedure) simply empower us to extend time in appropriate cases and we should exercise the discretion to do so in order to give effect to the overriding objective in rule 2(1) of the Rules to deal with cases fairly and justly. We note, and respectfully adopt so far as it relates to the absence of any equivalent provision toCPR 3.9 (1) in the Rules, the reasoning of Black J in R (oao Howes) v Child Support Commissioners (see: [35] and [36] above). 57. Exercising our discretion to give effect to the overriding objective may however, and often will in practice, involve consideration of some or all of the criteria (a) to (i) set out inCPR 3.9 (1). ”
