The Court of Appeal upheld Mr Smith's appeal. It held that:
1. The principle in King also extends to workers who have been forced to take unpaid holiday. The ECJ in King had held that the right to paid holiday is a single composite right and the right to holiday and the right to payment for holiday are two aspects of that single right. It had also emphasised the importance of the right to paid holiday and that there can be no preconditions whatsoever to it. So, an employer who does not allow a worker to exercise the right to paid holiday must bear the consequences. The purpose of the right to paid holiday (and to be paid when the holiday is taken) is to ensure the worker has the requisite rest and relaxation for their health and safety. An employer cannot be allowed to benefit from not paying for holiday to the detriment of the worker's health.
2. On the question of whether Mr Smith's claim was in time, domestic law can provide for the loss of the right at the end of each holiday year. To lose it, the worker must actually have had the opportunity to exercise the right and the employer must be able to show that it:
a. specifically and transparently gave the worker the opportunity to take paid holiday;
b. encouraged the worker to take paid annual leave; and
c. informed the worker that the right would be lost at the end of the leave year.
Where the employer cannot show that, the right does not lapse but carries over and accumulates until termination when the worker is entitled to a payment for the untaken leave. That is what happened here and Mr Smith's claim was in time because it was made within three months of the termination of his engagement.
Whilst not strictly necessary (because Mr Smith succeeded in his claim under the provisions of the WTR rather than as an unlawful deductions claim), the Court of Appeal nevertheless went on to consider the issue of whether, for the purposes of an unlawful deduction from wages claim, a series of deductions is broken by a gap of three months or more. In Bear Scotland v Fulton (Bear Scotland) the EAT held that a gap of more than three months did break the gap, whereas the Northern Ireland Court of Appeal in Chief Constable of Police v Agnew (Agnew) reached the opposite view. The Court of Appeal gave a strong provisional (obiter) view that Agnew is correct. It did not support the reasoning put forward in Bear Scotland but rather considered that the "identification of a sufficient factual and temporal link between deductions will answer the question whether there is a "series" without the need to imply or infer a limit on the gaps between particular deductions".
