The appellant, Sachin, was convicted under Section 302 of the Indian Penal Code for murdering his wife. The prosecution's case was based on the 'last seen alive together' theory and an extra-judicial confession. The appellant argued that there were discrepancies in the prosecution's case, including contradictions in witness statements. The court ultimately held that the prosecution had established its case and the appellant had failed to explain his role in the offence. The conviction was upheld.
