Obstruction in form of a brick wall constructed on the only path to my house by my neighbours

I have a 3 storey house . I was using a path which connects through the NH and that path passes through the houses of 2 neighbours who are brother and sister in relation. The son of the brother, after 6 years of our living in the house and using the path , constructed a brick wall on the path and closed it. We are forced to live in a rented accommodation since the last 3 years even after having our owm house. The right to use the path was given in the form of an affidavit by both the brother and the sister stating that they have no issue if we use the disputed path as an approach to our property as it is the aole approach to the property. However , my parents not being that literate were played by them both as they gave the affidavit on a stamp paper with their signatures on it and a thumb impression by the brother but not attesting it , only the release date and details on it. I won the case in the SDM and district court to the highest level. But the son of the brother lost the case 3 times and now the brother is contradicting the facts of the affidavit by saying he gave a license and he revokes it now. I do not have any other approach to my property and the TCP approved plan shows the disputed path in the map as the approved site plan with the path in it connected through the NH. The matter is in high court shimla and the opposite council is hell bent on saying that it was a license that can be revoked and has been now. The disputed path is the only approach to our property and we have been already forced to live away in a rented accomodation because we cannot access the house since the last 3 years due to continuous contesting of legal suits. Even after winning everytime at district level courts and magistrate courts, im still outside my house and now the high court is elongating the suit which technically should not be admissable in the first place. Please tell me what should i do as i want to sell my house and the opposite party is constantly filing revisiom suits in order to stop me from selling my property and getting out of this misery as we have suffered huge losses worth crores and are now left with no option but to ask money from people to even buy food. Please help
