“We may in this respect refer to the judgment of two-Judge Bench of this Court in Col. B.J. Akkara (retd.) case (supra) where this Court after referring to Shyam Babu Verma case, Sahib Ram case (supra) and few other decisions held as follows: Such relief, restraining recovery back of excess payment, is granted by courts not because of any right in the employees, but in equity,in exercise of judicial discretion, to relieve the employees, from the hardship that will be caused if recovery is implemented. A Government servant, particularly one in the lower rungs of service would spend whatever emoluments he receives for the upkeepof his family. If he receives an excess payment for a long period, he would spend it genuinely believing that he is entitled to it. As any subsequent action to recover the excess payment will cause undue hardship to him, relief is granted in that behalf. But where the employee had knowledge that the payment received was in excess of what was due or wrongly paid, or where the error is detected or corrected within a short time of wrong payment, Courts will not grant relief against recovery. The matter being in the realm of judicial discretion, courts may on the facts and circumstances of any particular case refuse to grant such relief against recovery.”
