Sc/st act section 3 give your seggestion about my query

My father has some land issue with a sc person .due to that he filled sc/st act against my father.then all procedure witness and all that happened and my father was charged under 3 act.then first hearing was in taluca court. Some compromise happened in court and than a affidavit was presented before judge in which sc person said that he has done compromise with my father in 2.3 lakh rupees.in which 1lakh he has got now and remaining he will take after end of case.he(sc person) want no further proceeding with accusant(my father)and all have settled between us and i have no any problem or विवाद with accusant .these all things are written in affidavid on which sign of both parties and OF JUDGE ARE.on that basis court gave my father BAIL. Then hearing started in special sc/st court. We filled a criminal revision pettion in high court.high court accepted the pettion and now hearing in high court is on 19sept. But that sc person is so cunning he does not want to do compromise now.he want remaning money and also land which is of my father name.can this sc/st act be quashed by high court on the basis of affidavit signed by sc person and taluca court judge.because this is our last hope otherwise that sc person will not compromise on land also this is his business to trap service class person
