Criminal Appeal under S.14(A) SC/ST Act by the newly added A9 (Ruthala Ramana alias Ramana Master, 65-year-old retired teacher, brother of A1-A2) against the order dt. 11.09.2024 of the Special Sessions Judge for SC & ST Cases-cum-XI ADJ, Visakhapatnam in S.C.No.10/2015, whereby he was added as accused under S.319 Cr.P.C. at the judgment stage of a 2008 murder/SC-ST atrocity case (Crime No.79/2008, Makaravapalem P.S.). HELD: (i) Ex.P.8, the de facto complainant's first information to police, is not substantive evidence, being usable only for contradiction/corroboration when its maker is examined; (ii) S.161(3) Cr.P.C. statements can neither corroborate a witness nor contradict another witness - their sole use is to contradict the maker per the S.162(1) proviso r/w S.145 Evidence Act; (iii) a S.145 contradiction is always between a witness's own court deposition and his own police statement, never across witnesses; omissions surfacing in court testimony fall under the explanation to S.162, and unproved, unconfronted police statements cannot be used suo motu - contradictions must be marked per Rule 58-B (framed per BNSS Ss.180/183) and proved through the Investigating Officer (V.K. Mishra); (iv) the purpose of contradiction is impeachment of credit under S.155(3) Evidence Act, not substitution of substantive evidence; falsus in uno is inapplicable; (v) S.319 power extends from pre-charge stage till pronouncement of judgment (Sukhpal Singh Khaira guidelines), but the required satisfaction exceeds the charge-framing 'prima facie' standard though falls short of conviction-certainty (Hardeep Singh; Labhuji Thakor; Brijendra Singh - investigation material suggesting otherwise must be looked into; Hetram - cross-examination cannot be ignored); (vi) P.W.4's admitted police statement naming the proposed accused was no positive assertion of witnessing, she denying knowledge of which accused beat the injured; P.Ws.7 and 9 were not eye-witnesses (P.W.18); and P.W.18's investigation placed the proposed accused at a marriage dinner at Visakhapatnam Steel Plant on 01.12.2008, 7-10 p.m., away from the scene, prompting deletion of his name for want of evidence, with no protest petition. Required S.319 satisfaction not made out; the order suffers serious infirmity. Appeal allowed; summoning order and consequent summons dt. 20.12.2024 set aside, observations confined to the S.319 prayer and the trial judge left free to appreciate evidence independently.
