As per case facts, a passenger fell from a bus as it moved forward, and its rear wheel ran over her, leading to her demise. The driver was convicted of ... culpable negligence by the lower courts. The question arose whether, based on these facts, a conclusion of negligent driving necessarily follows, particularly if there was adequate evidence to show the driver moved the bus suddenly or without a conductor's signal. Finally, the Supreme Court determined the evidence was insufficient to establish criminal negligence. It emphasized that negligence cannot be presumed merely because a passenger fell while boarding, especially without further proof that the driver initiated movement suddenly or without proper authorization. Consequently, the court found the conviction unsustainable and acquitted the appellant.
