Mohamud v W M Morrison Supermarkets plc [2014] EWCA Civ 116; [2014] WLR (D) 68
‘Where an employee’s duties included interaction with customers but did not involve any element of keeping public order or exercising authority over them, the employer was not vicariously liable for an assault by the employee on a customer. The mere fact of contact between a sales assistant and a customer, which was plainly authorised by an employer, was not of itself sufficient to fix the employer with vicarious liability.’
