remand of criminal case to lower court

my dad was wantedly trapped by ACB in demand of bribe case in 2003.DSP and complainant were colluded.Our lawyer was not good and he didn't discussed case details with my dad,so we lost the case and my dad was convicted in 2010.In 2010 we appelead in the telangana high court.At this point of time we learned that ACB officials adjusted fake irrelevant documents in lower court.We want to question about these documents in lower court as these are the documents on which whole case is based,so the question is Can we remand back our criminal case to lower court, and by what time hearing will start?Will they take years or will they start hearing our case immediately? Please refer relevant provisions.
