The employer applied for judicial review of an arbitrator's award that ordered it to repay funds to an employee.
The employee, a station collector, had erroneously credited customers' debit cards instead of debiting them, resulting in a shortage.
The arbitrator found the employee responsible for the shortage under the collective agreement but held the employer could not recover the funds because it failed to mitigate its loss.
The Divisional Court granted the application and quashed the award, finding the arbitrator's imposition of a duty to mitigate unreasonable in the context of a contractual debt and the collective agreement's clear language.
