The Court refused the Claimant's application. It found that, although it was open to the parties to agree an extension of the 21-day relevant period, no such agreement had been reached here, and the court had no express power to intervene and vary or rewrite the terms of a Part 36 offer that a defendant had chosen to make.
Self-contained procedural code
The court stressed the importance of clarity and objectivity in any procedure rule, but particularly Part 36, "a self-contained procedural code about offers to settle made pursuant to the procedure set out in this Part" (CPR 36.1(1)). A procedural code intended to be "self-contained" should be taken as procedurally finite, at least for the purposes of what might be procedurally possible within it. The position would be different where, for example, the court is asked to assess the meaning or status of an offer. The court also rejected the Claimant's contention that the absence of a prohibition in the CPR automatically incorporates or assumes facility to otherwise do something; there still has to be a procedurally recognised basis.
General case management powers
The court also rejected the Claimant's alternative submission that the court had jurisdiction to vary the relevant period under its general case management power set out in CPR 3.1(2)(a), on the basis that Part 36 was a self-contained code, and CPR 3.1(2)(a) refers to the power to adjust the time for compliance rather than time periods otherwise featured in rules. Although CPR 36.5(1) engaged questions of compliance in prescribing the form and content of a Part 36 offer, compliance with rules going to form and content should not be conflated with compliance with the time for doing something. Further, although the form and content of a Part 36 offer are subject to rules, there is no rule as to when an offer should be accepted, only rules going to the consequences of not doing so.
Offer open until withdrawn
The Master noted that the wording of the draft Order sought by the Claimant was not technically accurate in seeking an extension of "the expiry of the Part 36 offer". This is because the Claimant's offer was not a time-limited offer, and as such, remained open for acceptance until expressly withdrawn (which it had not been). This addresses a common misconception about how Part 36 offers work: despite offers having to remain open for acceptance for the 21-day "relevant period" in order to attract the specific costs and other consequences set out in Part 36, that is not a deadline for acceptance. The offeree can accept the offer at any time after expiry of the 21-day period unless the offer is expressly stated to be time-limited, or has been formally withdrawn, but the costs consequences will be different. The Master in Begum therefore noted that the Claimant was in fact applying to extend the "relevant period" as defined in CPR 36.3(g) such that, during that extended period, the Defendant could not withdraw the offer and, if accepted, the Claimant would have the Part 36 costs protection.
