NASAR ALI vs THE STATE OF UTTAR PRADESH

The Supreme Court held that a First Information Report (FIR) is not substantive evidence and can only corroborate or contradict the maker's statement under Sections 157 and 145 of the Evidence Act. The court emphasized the presumption of innocence until proven guilty and clarified that the maxim 'falsus in uno, falsus in omnibus' is not a mandatory rule but a cautionary principle regarding the weight of evidence. The conviction of the appellant under Section 302 IPC was upheld, reversing the acquittal by the Sessions Judge.
