58. The relief against recovery is granted by courts not because of any right in the employees, but in equity, exercising judicial discretion to relieve the employees from the hardship that will be caused if recovery is ordered. But, if in a given case, it is proved that the employee had knowledge that the payment received was in excess of what was due or wrongly paid, or in cases where the error is detected or corrected within a short time of wrong payment, the matter being in the realm of judicial discretion, courts may, on the facts and circumstances of any particular case, order for recovery of the amount paid in excess.
