Harpur Trust v Brazel

Factual and Procedural Background

The Respondent is a visiting music teacher engaged by the Appellant to provide instrumental tuition during school terms. She works irregular hours, receives pay only for the hours actually taught, and does not work during school holidays. Under her permanent contract she is entitled to 5.6 weeks’ paid annual leave, historically treated as being taken in three equal tranches during the Christmas, Easter and summer breaks.

Until September 2011 the Appellant calculated holiday pay by averaging the Respondent’s remuneration over the 12 paid weeks preceding each holiday (the “Calendar Week Method”), as required by regulation 16 of the Working Time Regulations 1998 (“WTR”) read with section 224 of the Employment Rights Act 1996 (“ERA 1996”). From September 2011 the Appellant adopted a “Percentage Method”, paying 12.07 % of the Respondent’s term-time earnings to reflect the ratio that 5.6 weeks bears to the assumed 46.4-week working year.

The Respondent brought proceedings for unlawful deductions from wages. The Employment Tribunal dismissed the claim, holding that further pro-rating was permissible. The Employment Appeal Tribunal allowed the Respondent’s appeal. The Court of Appeal dismissed the Appellant’s further appeal. The Supreme Court (constituted by Judge Hodge, Judge Briggs, Judge Arden, Judge Burrows and Judge Rose) now determines the final appeal.

Legal Issues Presented

1. Whether, under the WTR, the statutory leave entitlement of part-year workers on permanent contracts must be prorated to reflect weeks in which no work is performed.
2. Whether EU law (in particular article 7 of the Working Time Directive and the so-called “conformity principle”) requires the WTR to be interpreted so as to mandate such pro-rating.
3. Whether either of the Appellant’s alternative calculation models—the “Percentage Method” or the “Worked Year Method”—can be read into the WTR by means of conforming interpretation.

Arguments of the Parties

Appellant's Arguments

• The “conformity principle”, derived from Court of Justice of the European Union (“CJEU”) jurisprudence, links paid annual leave to periods of actual work; therefore non-working weeks should reduce leave entitlement.
• Applying the Calendar Week Method can result in part-year workers receiving holiday pay that is disproportionately high compared with full-time or regular part-time staff, producing allegedly “absurd” outcomes.
• The WTR should be construed, via the Marleasing duty of conforming interpretation, to adopt either the Percentage Method (12.07 % of annual earnings) or the Worked Year Method (pro-rating the 5.6 weeks by the fraction of the 46.4-week working year actually worked).
• Section 229(2) ERA 1996 permits the court to adjust the reference period in order to reach a “just” result.

Respondent's Arguments

• The statutory text is clear: regulations 13 and 13A confer 5.6 weeks’ leave each year, and regulation 16 fixes the rate of pay by reference to section 224 ERA 1996, which expressly ignores zero-pay weeks.
• EU law sets only a minimum entitlement; member states may provide more generous rights. The WTR therefore remain compliant even if they confer proportionately greater benefits on part-year workers.
• The Appellant’s alternative methods conflict with the language and structure of the WTR, create administrative complexity, and would amount to judicial redrafting.
• Section 229(2) ERA 1996 is confined to apportioning atypical payments (e.g. bonuses) and cannot be used to rewrite the statutory holiday-pay formula.

Court's Reasoning and Analysis

The Court began by examining the legislative text. Regulations 13 and 13A set a fixed entitlement of 5.6 weeks’ leave; unlike regulation 16, they contain no mechanism for excluding unpaid weeks. Where Parliament wished to apportion leave it did so expressly—for example in regulations 13(5), 13A(5) (employment commencing mid-year) and regulation 14 (on termination).

Turning to EU law, the Court accepted that CJEU authority generally ties leave to work performed but emphasised article 15 of the Directive, which permits member states to confer more generous rights. Because the WTR confer at least the Directive’s minimum, the UK legislature was free to be more favourable. Hence the conformity principle is not the organising principle of the WTR.

The Court rejected the Appellant’s alternative methods. The Percentage Method disregards the statutory concept of a “week’s pay” and contradicts regulation 16. The Worked Year Method would redefine “week”, requires complex accrual calculations and lacks statutory foundation. Both schemes would impose significant administrative burdens contrary to the Directive’s aim of avoiding undue constraints on employers—particularly small businesses.

Alleged anomalies or “absurd” results did not justify rewriting the regulations; general rules can produce outliers without defeating legislative intent. Section 229(2) ERA 1996 is limited to apportioning atypical payments and cannot be pressed into service to reformulate holiday pay.

Holding and Implications

APPEAL DISMISSED.

The statutory entitlement of a part-year worker on a permanent contract is 5.6 weeks’ paid leave, calculated by averaging remuneration over the prescribed reference period (12 weeks at the relevant time; now 52 weeks) while disregarding any whole weeks with no pay. Employers may not prorate that entitlement to reflect non-working weeks. The decision confirms that domestic law can lawfully provide part-year workers with proportionally higher holiday pay than full-time staff and settles the calculation method for thousands of casual and term-time workers throughout the jurisdiction, without setting new precedent beyond authoritative construction of the WTR.
