This supreme court decision extends the ruling on vicarious liability to the advantage of futue claiamnts in cases that would have previously failed.The court ruled that Morrisons was "vicariously liable" for Mr Khan's actions.It has broadened the law which holds employers vicariously liable for the acts of their employees who commit a crime whilst at work.Previously an employer could argue that an employee was acting for entirely personal reasons - "on a frolic of their own" if they committed a crime. This judgement widens the rules on vicarious liability and those circumstances  where a company can be held liable for the actions of an individual member of staff.
