Luc Guilliey v OCAPAC Mauritius Holding Ltd (Mauritius)

Why It Matters

The decision will clarify whether statutory gratuity can be substituted by contractual bonuses, impacting payroll compliance and contract design for Mauritian employers.

Key Takeaways

• Appeal challenges contract’s “statutory gratuity” versus 13‑month bonus.
• Lower court reclassified gratuity as contractual bonus under section 33C.
• Monthly salary not 1/12 of annual salary, breaching statute.
• Grounds D, E1, E2 highlight statutory and mathematical inconsistencies.
• Outcome could reshape Mauritius’ end‑of‑year gratuity contract drafting.

Summary

The hearing in Luc Guilliey v OCAPAC Mauritius Holding Ltd centers on an appeal over the interpretation of a statutory end‑of‑year gratuity clause in the employee’s contract. The appellant argues that the contract expressly promises the statutory gratuity under the End of Year Gratuity Act 2001, while the employer treated the 13th month payment as a contractual bonus, invoking section 33C of the Act.

Grounds D, E1 and E2 form the core of the appeal. Ground D contends the contract’s language creates a statutory entitlement, not an independent bonus. Ground E1 points out a mathematical flaw: the annual basic salary is divided into 13 installments, making each monthly payment less than one‑twelfth of the annual figure, contrary to the Act’s definition of basic wage. Ground E2 argues that the lower court’s reclassification creates a logical inconsistency, effectively converting a statutory right into a contractual arrangement.

The counsel repeatedly cited the contract annex (page 219) stating the salary is paid in 12 monthly installments plus a 13th month gratuity, and referenced the statutory provisions—section 32 defining the gratuity calculation and section 33C allowing an exception for a “bonus” under an agreement. The lower court’s judgment, noted on pages 410‑411, treated the gratuity as a bonus, a position the appellant disputes as illegal under the Act.

If the appellate court overturns the lower decision, it would reinforce strict compliance with Mauritius’ gratuity legislation, compelling employers to structure contracts and payroll calculations in line with the statutory 12‑month framework. The ruling could set a precedent affecting contract drafting, payroll systems, and litigation risk for companies operating in the jurisdiction.

https://www.jcpc.uk/cases/jcpc-2025-0029.html

Hearing date: 30 April 2026

Session: Morning session [Session 1 of 1]

Judgment date: 11 June 2026

Neutral citation: [2026] UKPC 25

Issue:

Does the definition of “Annual Basic Salary” in the employment contract between the Appellant and the Respondent (and the annex to that contract) violate the End of the Year Gratuity Act 2001 (“EYGA”)?

Facts:

The Appellant, a French national, was employed by the Respondent. His employment contract was deemed to commence from 1 September 2002, taking into account prior service with another company in the Respondent’s group.

By a letter from counsel on 24 May 2016, the Appellant notified the Respondent that he considered the employment relationship terminated by reason of the Respondent’s failure to comply with statutory payment obligations. The Appellant argued that the Respondent had structured his annual remuneration as 13 equal monthly payments to evade the statutory obligation to pay a separate end-of-year gratuity under the EYGA. He argued that the thirteenth instalment was misrepresented as being the end-of-year gratuity when in fact it constituted one-thirteenth of the annual basic salary agreed upon. He brought a claim for constructive dismissal, seeking severance allowance and related payments.

The Industrial Court summarily dismissed the Appellant’s claim. The Supreme Court held that the Industrial Court had erred in summarily dismissing the claim, but nonetheless dismissed the Appellant’s appeal on the merits. The Appellant now appeals as of right to the Judicial Committee of the Privy Council.
