Supermarket chain Morrisons has succeeded in its appeal to the Supreme Court against judgments that held it liable for an insider data breach caused by a disgruntled employee.
The breach occurred in 2014 when payroll data on thousands of Morrisons employees was leaked on a file-sharing website by Andrew Skelton, a member of its internal audit team.
A number of the affected employees subsequently brought proceedings against Morrisons personally and on the basis of what is termed vicarious liability for the acts of the employee.
