Trinidad and Tobago – Constitution. Where the appellant Commissioner of Police of Trinidad and Tobago had wrongly interpreted the law as rendering the respondent, the then Superintendent of Police, ineligible to write a qualifying examinatio, with a view to promotion to Senior Superintendent, the Court of Appeal had been right to declare the Commissioner's decision null and void and ultra vires the Police Service Act and the Police Service Regulations 2007. Accordingly, the Privy Council dismissed the Commissioner's appeal.
