NIRANJAN SINGH vs THE STATE OF UTTAR PRADESH(and connected appeal)

The Supreme Court held that Rule 109 of the Uttar Pradesh Police Regulations, which mandates daily submission of the police case diary to the Superintendent of Police, does not have a statutory basis and thus, non-compliance does not vitiate the trial. The court found that the failure to submit the diary daily did not undermine its credibility, especially as the lower courts did not question its authenticity. Consequently, the appeals were dismissed, affirming the lower court's decisions.
