The Uttarakhand High Court has held that the mere smell of alcohol on the breath of a driver, without scientific evidence such as a blood test or breathalyser test proving that the alcohol concentration exceeded the statutory limit, is insufficient to establish drunken driving or justify framing a charge under Section 105 of the Bharatiya Nyaya Sanhita (BNS). The Court emphasized that criminal liability, particularly for serious offences involving culpable homicide not amounting to murder, cannot rest on assumptions or subjective observations. Scientific evidence is essential where the law prescribes a specific standard for determining intoxication. Accordingly, the Court partly allowed a criminal revision petition and set aside the charge under Section 105 BNS while allowing the remaining charges to continue.
The case arose from a road accident in Uttarakhand in which the revision petitioner was driving a jeep from Shri Badrinath to Chamoli. During the journey, the vehicle allegedly lost control after its front tyre burst, overturned, and caused injuries to several passengers while resulting in the death of one occupant. Following the accident, the police registered a criminal case and initiated investigation. During the medical examination of the driver, doctors recorded that there was a smell of alcohol on his breath. However, no breathalyser examination or blood sample was collected to determine the actual concentration of alcohol in his bloodstream.
On the basis of the investigation, the Sessions Court framed charges against the accused under Sections 105, 125(a), 125(b), and 281 of the Bharatiya Nyaya Sanhita, 2023. Aggrieved by the framing of these charges, particularly the charge under Section 105 BNS relating to culpable homicide not amounting to murder, the accused approached the Uttarakhand High Court through a criminal revision petition, contending that the available evidence did not justify such a serious charge.
The petitioner argued that the prosecution had failed to establish that he was driving under the influence of alcohol in the manner required by law. Referring to Section 185 of the Motor Vehicles Act, 1988, the defence submitted that a person can legally be treated as driving under the influence only if the alcohol content in the blood exceeds 30 milligrams per 100 millilitres of blood, as established through a breathalyser or other recognised scientific test. Since no such examination had been conducted, the prosecution could not rely merely upon the smell of alcohol to presume intoxication.
The petitioner further contended that the accident was not caused by rash or intoxicated driving but by a sudden mechanical failure. Reliance was placed on the technical inspection report, which indicated that the accident occurred because the left front tyre of the vehicle burst, causing the driver to lose control. It was argued that there was no evidence demonstrating reckless driving, excessive speed, or any conduct suggesting that the accused had knowingly endangered the lives of passengers.
The State opposed the revision petition and supported the order framing charges. However, after examining the investigation records, the High Court carefully analysed the material collected during the investigation, including the technical inspection report, medical records, and witness statements. The Court found that none of the eyewitnesses had stated that the petitioner was driving rashly, negligently, or in a manner indicating that he was under the influence of alcohol. Likewise, the mechanical inspection report attributed the accident primarily to the tyre burst rather than to any negligent act of the driver.
Justice Alok Mahra observed that while the medical examination noted the smell of alcohol on the driver's breath, no blood sample, breathalyser examination, or any other scientific procedure was undertaken to establish the alcohol concentration in the accused's body. The Court emphasized that where Parliament has prescribed an objective statutory standard under Section 185 of the Motor Vehicles Act, criminal liability based on intoxication cannot be inferred solely from subjective observations such as smell. Scientific verification is indispensable before concluding that the statutory threshold has been crossed.
The High Court explained that the statutory limit under Section 185 of the Motor Vehicles Act exists to distinguish between mere consumption of alcohol and legally punishable drunken driving. A person may have consumed alcohol without necessarily exceeding the permissible limit or suffering impairment affecting driving ability. Consequently, the smell of alcohol alone cannot establish that a person was driving in violation of the law. The Court observed that criminal prosecution for serious offences requires objective evidence rather than presumptions based on appearance or smell.
Applying these principles to the facts of the case, the Court concluded that the prosecution had failed to place sufficient material to prima facie establish the ingredients necessary for framing a charge under Section 105 BNS. Since there was neither scientific proof of intoxication nor evidence demonstrating rash or dangerous driving, the essential ingredients required for culpable homicide not amounting to murder were absent at the stage of framing charges. Accordingly, the High Court set aside the charge under Section 105 BNS.
However, the Court clarified that its findings were confined only to the charge under Section 105 BNS. The material collected during the investigation was considered sufficient to permit the trial to proceed with respect to the remaining offences under Sections 125(a), 125(b), and 281 of the Bharatiya Nyaya Sanhita. Therefore, while the serious homicide-related charge was quashed, the criminal prosecution itself was not terminated and would continue before the trial court on the remaining allegations.
The judgment reinforces an important principle of criminal jurisprudence that scientific evidence assumes critical importance whenever a statute prescribes measurable legal standards. Courts cannot substitute statutory requirements with assumptions or subjective impressions. Particularly in road accident cases involving allegations of drunken driving, investigating agencies are expected to conduct timely breathalyser or blood alcohol tests so that the existence or absence of intoxication can be established through reliable forensic evidence rather than speculation.
The ruling also reflects the broader constitutional principle that criminal charges must be supported by adequate prima facie material before an accused can be subjected to trial for grave offences. Framing serious charges without objective evidence may unjustifiably expose an individual to prolonged criminal prosecution. By insisting upon compliance with statutory standards of proof, the Court reaffirmed that procedural fairness and scientific investigation are essential components of the criminal justice system.
In conclusion, the Uttarakhand High Court held that the mere smell of alcohol, without corroboration through a blood test or breathalyser establishing alcohol concentration beyond the statutory limit, cannot legally establish drunken driving or justify framing a charge under Section 105 of the Bharatiya Nyaya Sanhita. While allowing the prosecution to continue on other charges arising from the accident, the Court set aside the homicide-related charge for want of sufficient prima facie evidence. The judgment serves as a significant precedent emphasizing that criminal liability for intoxicated driving must rest upon objective scientific proof rather than suspicion or subjective observations, thereby strengthening the principles of fairness, legality, and evidentiary rigor in criminal prosecutions.
