The High Court’s decision in The Winros Partnership v Global Energy Horizons Corporation [2025] EWHC 3362 (Ch) confirms that contractual risk allocation in a CFA precludes unjust enrichment claims where the agreement already provides for the consequences of termination.
Background
The case concerned an appeal by The Winros Partnership (formerly Rosenblatt Solicitors) against a decision of Senior Costs Judge Gordon-Saker in the Senior Courts Costs Office. This was the second appeal in the long-running costs dispute between these parties; the procedural history and the abuse of process challenge to late-raised objections was considered in the First Judgment, covered in our earlier post.
The underlying dispute arose from a series of conditional fee agreements (CFAs) between Rosenblatt and its client, Global Energy Horizons Corporation, for litigation services. Three CFAs were entered: CFA-1, CFA-2, and CFA-3. The relationship deteriorated, leading Rosenblatt to terminate CFA-3 by accepting Global Energy’s repudiatory breach in a letter dated 24 February 2016. This termination was subsequently held to be valid by Trower J in earlier proceedings [§7].
In April 2016, Global Energy commenced proceedings under the Solicitors Act 1974 seeking detailed assessment of four bills rendered by Rosenblatt [§9]. The key bills were a 2012 bill (for work under CFA-2) and a 2016 bill (for work under CFA-3). Trower J had already determined that the 2012 bill was not a statute bill and conferred no immediate right to payment [§11]. The appeal focused on the 2016 bill, delivered shortly after termination, which Rosenblatt sought to have assessed. Rosenblatt had also commenced separate Chancery proceedings for damages arising from the termination, which were stayed pending the outcome of the costs assessment [§12, §37].
At the detailed assessment hearing, Global Energy raised “Objection 1”, contending that Rosenblatt was not entitled to payment of its fees for work done up to the termination date where no “win” had been achieved under the CFA [§4, §13]. The Senior Costs Judge framed the issue as: where a CFA retainer is terminated following the client’s repudiation, is the solicitor entitled to payment of fees if no success fee had been achieved? He concluded that Rosenblatt was not entitled to deliver the 2016 bill, that Global Energy was not liable to pay it, and therefore the bill must be assessed at nil [§65–66]. It was against this decision that Rosenblatt appealed.
Costs Issues Before the Court
The core costs issue was the entitlement of a solicitor to payment of fees under a conditional fee agreement terminated due to the client’s repudiatory breach, where the condition for payment of the success fee (a “win”) had not been met. The appeal required the court to determine:
-
-
- Whether the Senior Costs Judge erred in law in concluding that a solicitor could not recover fees (absent a success fee) following termination for repudiation, distinguishing the position from termination of an “ordinary” retainer for good cause.
- Whether Rosenblatt had an alternative claim in unjust enrichment (a quantum meruit) for a total failure of basis, which could found an entitlement to payment, and if so, whether such a claim could properly be determined within a detailed assessment proceeding under the Solicitors Act 1974.
-
The appeal proceeded on the agreed basis that CFA-3 was an entire contract and had completely replaced CFA-2 [§20, §23].
The Parties’ Positions
Rosenblatt’s Position: Rosenblatt contended the Senior Costs Judge erred. It argued that the long-established common law rule, as stated obiter in Richard Buxton (a firm) v Mills-Owens [2010] EWCA Civ 122, entitled a solicitor terminating an entire contract for good cause to be paid for work done [§27–28]. It submitted this principle should apply equally to CFAs. Crucially, Rosenblatt argued that its primary case on appeal was now a claim in unjust enrichment [§38, §57]. It contended that the basis for its work under CFA-3—performance leading to a “win” or, if not, termination under the agreement’s specific clauses—had totally failed when Global Energy’s repudiatory breach forced termination outside the contractual framework. Rosenblatt submitted that this created a vacuum allowing a restitutionary quantum meruit for the value of services rendered. It argued this claim could and should be determined within the detailed assessment.
Global Energy’s Position: Global Energy supported the Senior Costs Judge’s reasoning. It argued that CFA-3’s express terms, particularly clause 14.3, constituted a detailed contractual scheme allocating risk for termination due to the client’s failure to meet responsibilities, while leaving the common law damages remedy intact. Clause 14.3 provided [§14]:
“Rosenblatt can end this agreement if it believes the Client does not meet its responsibilities. If this happens, the Client will have to pay Rosenblatt’s fees for the work done to the termination date and disbursements.”
By choosing to accept a repudiatory breach instead of invoking clause 14.3, Rosenblatt elected a different remedial path (a claim for damages) [§37]. The contract had anticipated and provided for the scenario, allocating the risk that Rosenblatt would recover no fees if it did not use the clause 14.3 mechanism. Consequently, there was no room for a claim in unjust enrichment, as to allow one would upset the parties’ contractual risk allocation [§47–48]. Global Energy also argued that a freestanding unjust enrichment claim was not a matter for determination on a Solicitors Act assessment.
The Court’s Decision
Mr Justice Marcus Smith dismissed the appeal, upholding the Senior Costs Judge’s decision that the 2016 bill should be assessed at nil [§56]. The court’s analysis focused on two key areas: the claim in unjust enrichment and the propriety of the detailed assessment forum.
On the unjust enrichment claim, the court held there had been no total failure of basis. Applying principles from Dargamo Holdings Ltd v Avonwick Holdings Ltd [2021] EWCA Civ 1149 and Barton v Morris [2023] UKSC 3, the court emphasised the “Obligation Rule” and the importance of respecting contractual risk allocation [§41–49]. CFA-3’s clause 14 was a detailed provision anticipating various contingencies, including client non-performance (clause 14.3). This clause expressly stipulated the financial consequence: payment of normal fees and disbursements, but no success fee [§53].
The court found that while the common law remedy for repudiatory breach co-existed with these contractual terms, its existence did not create a vacuum allowing a restitutionary remedy that duplicated or circumvented the specific risk allocation in clause 14.3 [§54–55]. The parties had expressly agreed what would happen if Rosenblatt ended the agreement because Global Energy did not meet its responsibilities. To permit a quantum meruit claim in these circumstances would unjustly redistribute the risks expressly allocated by the contract. The court concluded that the common law remedy was a “last resort”, really intended for those cases not anticipated in clause 14 [§55]—and since clause 14.3 specifically addressed this scenario, there was no gap for restitution to fill. For substantially the same reasons as the Senior Costs Judge, Rosenblatt’s restitutionary claim failed [§56].
Obiter, the court also addressed the appropriateness of determining such a claim within a detailed assessment [§57–64]. Relying on Jones v Richard Slade and Co Ltd [2022] EWHC 1968 (QB), it held that the Solicitors Act assessment process is a regulatory review of a bill’s reasonableness, not a vehicle for enforcing debts or determining generalised claims such as unjust enrichment [§60–61]. While the court had jurisdiction to decide the point, it was not the appropriate forum [§63]. Such claims, if genuinely arguable, should be pursued in separate High Court proceedings, with the assessment potentially stayed. The effective dismissal of the claim within the assessment was therefore correct [§64].
