The Supreme Court has reiterated that an accused's statement under Section 313 CrPC cannot by itself establish guilt when the prosecution has failed to prove its case. The Court observed that in a case based on circumstantial evidence, the prosecution must first establish a complete and reliable chain of circumstances. An inadequate explanation by the accused cannot be used to repair missing links in that chain. The Court also examined weaknesses in the evidence relied upon against the accused, including the last-seen theory and forensic material. Finding the prosecution case insufficient to meet the required standard of proof, the Court set aside the conviction and acquitted the accused. The ruling reinforces the principle that the burden of proving guilt remains with the prosecution.
