Brierley v Prescott – Retrospective CFAs
In Brierley v Prescott  EWHC 90062 (Costs) Master Gordon-Saker was asked to rule on whether an attempt to correct a CFA that was allegedly defective had succeeded as a result of the solicitors and their client entering into a retrospective CFA after the conclusion of the case.
The Master held that this attempt failed as, following Arkin v Borchard Lines Ltd  NLJR 970, an agreement made after the conclusion of the proceedings to vary a CFA relating to those proceedings would be unenforceable as contrary to public policy. Further, the Master doubted that a solicitor could comply with the CFA Regulations 2000 where the proceedings had already concluded and the costs had already been incurred.
Oyston v Royal Bank of Scotland – Deed of Variation
In Oyston v Royal Bank of Scotland  EWHC 90053 (Costs) Master Hurst was asked to consider a CFA where the success fee was stated as being 100% plus £50,000 if the damages recovered exceeded £1 million. It was clear that the CFA was defective in that the success fee exceeded the maximum of 100% and would therefore be unenforceable. However, the claimant’s solicitors had sought to correct this defect by entering into a Deed of Variation with their client to remove the reference to £50,000. Alternatively, they sought severance of the offending words. Again, these attempts to correct the defects in the original CFA failed.
The Master held that the Deed of Variation was ineffective to rectify the situation as against the paying party. By that date the issues between the parties had been resolved. Following the decision of the Privy Council in Kellar v Williams (Appeal No.13 of 2003)  UKPC 30, he held that it cannot be right that a Deed of Variation can be used to impose a greater burden on the paying party than existed before judgment. However, he expressed no view as to what would have been the outcome if the Deed of Variation had been entered into before the conclusion of the case.
Further, the attempt to remedy the problem by severance also failed as it would be contrary to public policy.
As Master Hurst summarised, “If either the Deed of Variation or severance were to be permitted late in the day, this would have the effect of enabling virtually all defective CFAs to be put right late in the day, even if this was only after the paying party had pointed out the alleged defects.”
Brennan v Associated Asphalt Ltd – Deed of Rectification
In Brennan v Associated Asphalt Ltd  EWHC 90052 (Costs), another case heard by Master Hurst, the Court was faced with a CFA which stated that the claimant could not recover from the opponent that part of the success fee which related to postponement of charges and disbursements (“as set out in paragraph (a) and (b) at Schedule 1”). Schedule 1 of the CFA stated that the success fee was 50% and reflected a number of factors including (a) and (b) which related to the postponement elements. However, the agreement did not then specify how much of the success fee was actually attributable to the postponement elements and the defendant therefore argued that this was a breach of Regulation 3(1)(b) of the CFA Regulations 2000.
The Master held that this was indeed a breach of the Regulations. However, he then went on to find that this was not a material breach as, following the Court of Appeal’s decision in Titchband v Hurdman  EWCA Civ 718, “the failure to specify a postponement element means that nothing in respect of this would ever be recoverable from the client”.
However, during the course of the detailed assessment proceedings, once the defendant had raised their concerns in relation to the validity of the CFA, the solicitors and their client entered into a Deed of Rectification. At the hearing before Master Hurst, the claimant did not seek to rely on this document other than as confirmation as to the state of mind of the parties at the time the CFA was entered into. Nevertheless, again on the basis of Kellar v Williams, Master Hurst did express considerable misgiving as to whether a subsequent arrangement made between the solicitor and client, which produced a larger costs bill than the original agreement, would have been effective against the defendant to correct a materially defective CFA. A larger bill would be the inevitable consequence if the original agreement was defective.
The above cases of Brierley, Oyston and Brennan give a very clear indication that attempts to correct defective CFAs, at least when made after the conclusion of the case, are likely to fail regardless of whatever ingenious schemes claimant solicitors may come up with.
