Hey Mshrid,
I have gone through your query and understand that you are distressed about the unfairness that has happened to your family. Here I am to give you some advice so that you can file a review petition regarding the same:
According to Article 137 of the Indian Constitution, the Supreme Court has the power to review the previous judgments but, only under certain exceptional circumstances. In reference to this law, you can file the petition when there is an error on the face of the record or there is the discovery of new and important evidence, which was previously not there. The main thing is whether the new evidence or the error is strong enough to get the file open of the case again and get the judgment reconsidered.
You can file the review petition in the Supreme Court but you will be successful only if will be able to prove a new material fact as evidence or a substantial error in the record.
Please make sure that the court has discretion in such cases as was seen in Union of India v. K.V. Jankiraman (1991). In this case, the Supreme Court has held that back wages should not be awarded in full unless there are strong grounds of facts as cases like this are subjected to the facts of the case.
Additionally, in the case of Dharampal Satyapal Ltd. v. Deputy Commissioner of Central Excise (2015), the Supreme Court has held that the review petition shall only be approved in certain rare circumstances, not for the sake of re-arguing the case for personal satisfaction.
As both your parents have passed away, I know the life and law have been unfair to you but there are only a few chances that you will get the full wages back.
I hope all your doubts are cleared but still, if you need some assistance, then feel free to connect with me on LinkedIn. (www.linkedin.com/in/pankhuri-rastogi-9221b2289)
