Should i file review petition

You can take a chance but frnakly speaking in Supreme Court it is not so effective ti file Review as the scpe of review is loimited to any errors in judgment apparant on face. If the Judgment upholds the decision of High Court but calculated wrongly the wages then only you may file review but if the court has reasoned 60% wages then i advise to drop the idea and accept what has been granted. Since even your father is not alive now you cannot file even for defamation

Thank you sir for your response but my father has worked in the corporation for 24 years he was 40 years old when he was terminated their has been an incidence where my father found that he was drawing less salary than his junior he approves  the higher authority with a letter and comparison of salary of him and his junior but no action was taken then he asked their union for help regarding this unfairness and they send a letter after that only the matter was resolved .An the enquiry report which led to the decision of termination was found to be based on oral evidence by the  investigating team.The point is that they hv been unfair to him not once but twice .Twice the authority to are the highest for providing justice to their employee .They didn't even thought once before terminating that one wrong decision would ruin the life of their own employee .The consequence of their harsh decision .The court has not mentioned anywhere why they think my father doesn't deserve full back wages when everything against him was found fake.
