3.1 Precedents cited
Appellate procedure: raising a new point
On whether the employer could newly argue “no restraint of trade” on appeal, the Court allowed the point to be taken as a pure point of law, applying the approach summarised in
Singh v Dass [2019] EWCA Civ 360 (itself drawing on Mullarkey v Broad [2009] EWCA Civ 2 and
R (on the application of Humphreys) v Parking and Traffic Appeals Service [2017] EWCA Civ 24; [2017] RTR 22).
The Court emphasised caution, but considered it desirable to resolve an important point of principle.
Foundations of restraint of trade in employment
The Court located the modern framework in the classic House of Lords authorities:
Nordenfelt case [1894] AC 535,
Mason v Provident Clothing and Supply [1913] AC 724, and
Herbert Morris Ltd v Saxelby [1916] 1 AC 688.
A key passage from Lord Parker in Herbert Morris Ltd v Saxelby was treated as continuing good law: in employment, restraints are not justified merely because the employee acquires skill and knowledge; justification traditionally lies in protection of customer connection and confidential information.
Scope of the doctrine: “substance not form” and financial disincentives
The Court relied on the flexible “rule of reason” synthesis in Quantum Actuarial LLP v Quantum Advisory Ltd [2021] EWCA Civ 227, particularly:
the focus on practical effect (not “legal niceties”), assessment as at the time of contracting, and the possibility that restraints may be indirect or operate through economic pressure.
The judgment also referenced the “rule of reason” line including Esso and the “trading society”/accepted machinery concepts (including Peninsula Securities), as part of the broader doctrinal landscape described in Quantum Actuarial LLP v Quantum Advisory Ltd.
Clawbacks and conditional benefits: distinguishing categories
The employer placed strong reliance on Steel v Spencer Road LLP [2024] ICR 137, which concerned repayment of a discretionary bonus if the employee left or gave notice within a short “clawback” period.
The Court of Appeal accepted Steel as correctly decided on its facts, but rejected any broad reading that the doctrine only applies to clauses directly restricting post-employment activity.
Earlier authorities discussed included:
-
Electronic Data Systems Ltd v Hubble (unreported) 20 November 1987:
treated as limited precedential value because the Court of Appeal merely held that the employee’s restraint-of-trade defence was arguable (summary judgment was not appropriate).
-
Marshall v NM Financial Management Ltd [1997] ICR 1065 (and the first-instance decision at [1995] ICR 1042):
cited for the settled point that indirect restraints can arise through loss of a benefit (Millett LJ), and for the characterisation of a clause as a “financial disincentive” to compete unless justified.
-
Sweeney v Peninsula Business Services Ltd [2004] IRLR 49:
used to illustrate that not every condition relating to continuing employment or service length is a restraint; context and effect matter.
Legitimate interests: workforce stability
On legitimate interest, the Court referenced Dawnay, Day & Co Ltd v de Braconier D'Alphen [1997] IRLR 442.
In that context it discussed the line of cases on “poaching” and workforce stability including Ingham v. ABC Contract Services (12 December 1993, C.A.) and
Hanover Insurance v. Schapiro [1994] IRLR 82.
The Court noted the category of “maintaining a stable, trained workforce” but observed its scope remains ill-defined; for the appeal it proceeded on the assumption that such an interest could exist here.
Reasonableness and onus
The Court reiterated that the employer bears the burden of justification, citing Harcus Sinclair LLP v Your Lawyers Ltd [2022] AC 1271.
It treated lack of legal advice and inequality of bargaining power as relevant considerations, citing Proactive Sports Management Ltd v Rooney [2011] EWCA Civ 1444 and Schroeder v Macaulay [1974] 1 WLR 1308.
It also noted that high-end “star” cases (such as Warner Bros v Nelson [1937] 1 KB 209) are of limited assistance in low-wage employment contexts.
3.2 Legal reasoning
(a) The doctrine applied: repayment clauses can restrain trade in substance
The Court rejected the employer’s attempt to characterise the scheme as outside restraint of trade because it did not bar resignation and was said to be “unconditional” debt repayment.
The Court’s reasoning was practical: because employment contracts cannot be specifically enforced against employees (and injunctions compelling work are constrained by statute), the relevant question is whether the clause in substance hampers freedom to work elsewhere by imposing a post-employment financial burden.
A clause requiring repayment of sums equivalent to salary (or large sums said to reflect “training”) can operate as an indirect post-termination restraint and therefore requires justification.
(b) Legitimate interest: assumed but not determinative
Although the county courts had accepted an employer interest in retaining staff and protecting training investment, the Court of Appeal reframed the analysis in orthodox terms:
the interest was not simply “avoiding profit loss” or capturing the employee’s enhanced market value, but (at most) maintaining a stable, trained workforce—subject to strict reasonableness control.
(c) Reasonableness: why the clause failed
The Court evaluated reasonableness as at the time of contracting, without hindsight (even if subsequent events may evidence the contract’s nature).
It acknowledged that instalment repayment (rather than a lump sum acceleration clause) was a moderating feature.
However, it found the scheme went too far for two principal reasons:
-
Over-breadth as to triggers:
repayment applied regardless of why employment ended (other than redundancy), including where the employee was dismissed on short notice, or left for reasons unrelated to competition, pay, or sector.
-
Economic reality at low pay:
the effect was to retrospectively render the early months of low-paid work close to the position of an unpaid intern (albeit with a repayable “loan”), which the Court regarded as beyond what was reasonably necessary to protect workforce stability.
While the Court did not decide the appeal on the accuracy of the training-cost calculation, it expressed scepticism about aspects of the methodology and noted the artificiality of treating substantial portions of the working day as valueless to the employer where the employee’s time was being billed to clients.
