In Scottbridge Construction Ltd v Wright the Court of Session upholds the EAT's decision that a "nightwatchman" who was required to be on his employer's premises for 14 hours each night was entitled to be paid the national minimum wage in respect of all those hours, even though, while required to respond to an alarm at any time, he only had to undertake specific tasks that took around four hours a night, and was permitted to sleep if he chose to when not carrying out those tasks.
