Judicial review – Delay. When considering whether an application for leave to apply for judicial review had been sufficiently prompt, the presence or absence of prejudice or detriment was likely to be the predominant consideration. The Privy Council, in allowing the appellant's appeal from Trinidad and Tobago, ruled that the judge had been required to have regard to prejudice and detriment before reaching a conclusion on whether to set aside leave to apply for judicial review, and, accordingly, he had exercised his discretion in setting aside leave on an erroneous basis. The court further ruled that the Court of Appeal's approach, which had sought to insulate prejudice and detriment, had also been flawed.
