Employment – Discrimination. Trinidad and Tobago had two classes of police officer, regular police officers (RPOs) and special reserve police officers (SRPs). The issue was whether, by virtue of section 4(d) of the Constitution of Trinidad and Tobago, the claimant present and former SRPs were entitled to equal treatment with RPOs. The Privy Council, in dismissing the claimants' appeal, held, inter alia, that the nub of the matter was whether the claimants and their comparators had been doing the same work or work which was not materially different. The courts below had found, as a fact, that the SRPs had performed duties of significantly lesser responsibilities than had the RPOs. There was no sufficient reason for departing from the normal practice, which was not to go behind the concurrent findings of fact in the courts below.
