Gedeon Mahabir v Public Service Commission and another (Trinidad and Tobago)

A public service commission may make a promotion decision with retroactive effect even if the officer has left service by the decision date, provided the officer held the relevant office when the promotion took effect. A statutory promotion procedure is not invalidated automatically because its prescribed steps were not followed. The court must consider legislative intention, the procedure’s purpose, the consequences of non-compliance and the facts, including substantial compliance. Where all qualified candidates are assessed transparently against agreed criteria, and the omitted steps add no further protection or opportunity for fair representations, the promotion decision may remain lawful. Eligibility requirements imposed by the statutory scheme remain binding.

The appellant, a Prison Officer I, challenged a points-based promotion process for advancement to Prison Officer II. The Public Service Commission promoted the first 180 officers on the final order of merit list, with effect from dates in December 2011. The appellant ranked 181st. Five promoted officers had retired or resigned by the date of the promotion decision.

Rajkumar J dismissed the judicial review claim on 17 June 2015 (CV 2013-03161). The Court of Appeal dismissed the appeal on 8 June 2021 (P184 of 2015). The issues before the Privy Council were whether section 121(1) of the Constitution of Trinidad and Tobago authorised retroactive promotion of officers who had left service, and whether failure to produce the lists and give notices required by the Public Service Commission Regulations rendered the process unlawful.

The Board dismissed the appeal on both grounds.

1. Retroactive promotion. Section 121(1) of the Constitution of Trinidad and Tobago confers a broad power to appoint, including by promotion. The words limiting powers of removal and discipline to persons holding or acting in office do not qualify the appointment and promotion power. That power can therefore operate retroactively. The critical date is the date on which the promotion takes effect, not the date on which the decision is made. The five officers held office on the relevant dates in December 2011, so the promotions were lawful. This interpretation also promoted orderly administration and avoided penalising candidates for delay in the promotion process.
2. Interpretation Act argument. The Board did not determine whether section 42 of the Interpretation Act qualified the constitutional power. The issue had not been raised below, required evidence about when the officers first performed higher-office functions, and could not fairly be determined for the first time on appeal.
3. Regulation 168. The Board rejected the Court of Appeal’s reasoning that the order of merit list itself constituted the list required by regulation 168(2). The respondents correctly conceded that regulation 168 had not been operated in that literal manner. The relevant question, applying R v Soneji [2005] UKHL 49; [2006] 1 AC 340 and the substantial-compliance analysis discussed in A1 Properties (Sunderland) Ltd v Tudor Studios RTM Co Ltd [2024] UKSC 27; [2025] AC 1075, was whether non-compliance was intended to invalidate the promotions.
4. Purpose and substantial compliance. Regulation 168(2) is intended to provide the Commission with a shortlist selected by the Commissioner, while regulation 168(3) protects senior officers not recommended by giving them notice and an opportunity to make representations. Here, the Commission deliberately obtained the complete list of qualified officers and assessed all of them against the regulation 172 criteria through an agreed, transparent points-based system. No unfairness resulted from the absence of a separate shortlist or notice because the appellant had opportunities to challenge and increase his own score. A subjective override by the Commissioner was unnecessary and would have undermined the agreed system. The substance of the protections and fairness requirements was therefore provided, making the promotions lawful.
5. Additional consideration. The possibility under regulation 170 of departing from the Regulations in the best interests of the Prison Service further indicated that compliance with regulation 168 was not an inflexible legal precondition to exercising the promotion power.
