The Supreme Court of India has agreed to examine whether police can lawfully enter a private residence and conduct a breath analyser test on its occupants under Bihar’s prohibition law and has gone further by suo motu questioning the constitutional validity of two key provisions of the Bihar Prohibition and Excise Act, 2016. A bench of Justices Sanjay Karol and N Kotiswar Singh was hearing an appeal filed by the State of Bihar against a Patna High Court judgment which held that a breath analyser test alone cannot be treated as conclusive proof of alcohol consumption.
During the hearing, the Court went beyond the issues raised in the appeal and decided to examine the constitutional validity of Sections 37 and 75 of the Act, assessing whether these provisions permit intrusive testing practices, including entry into private residences for alcohol detection. The next hearing is scheduled for 24 April. Bihar, civil liberties advocates and marginalised communities, who have borne the brunt of the law’s enforcement are all watching closely.
The Case That Triggered A Constitutional Question
The case stems from an incident on 2 May 2024, when an excise team visited the temporary residence of a Senior Treasury Officer in Kishanganj and subjected him to a breath analyser test, which reportedly indicated an alcohol concentration of 41 mg per 100 ml. On this basis, he was arrested and an FIR was registered against him, with the prosecution relying solely on the breath test and no blood or urine test conducted.
The Patna High Court quashed the FIR, ruling the evidence insufficient and observing that “no conclusion with regard to consumption of alcohol by a person can be made merely because the breath smells of alcohol or the gait is unsteady or the speech incoherent consumption of alcohol can only be ascertained by way of blood or urine tests.”
Bihar challenged this before the Supreme Court, arguing that Section 75 of the Act allows authorities to conduct breath analysis and that such reports are admissible as evidence, making the breath analyser test sufficient to justify registration of an FIR. The Supreme Court was unconvinced enough to expand the inquiry on its own initiative, a move that signals the depth of the constitutional concerns at play, particularly around the right to privacy within one’s home.
Nine Years Of Prohibition
Bihar’s blanket ban on alcohol has been in force since April 2016, when Chief Minister Nitish Kumar’s government enacted it, citing the need to protect families especially women, from the social harms of alcohol abuse. The law has had measurable benefits in reducing domestic violence. Yet the enforcement record tells a deeply troubling parallel story.
Till March 2025, over 936,000 prohibition cases were registered and 1.43 million people arrested, with authorities seizing millions of litres of liquor and auctioning tens of thousands of vehicles. The human cost has been equally staggering: since the ban’s rollout, Bihar has recorded 190 deaths from spurious liquor, with districts like Saran, Siwan, Gaya and Bhojpur among the worst affected, the 2022 Saran hooch tragedy alone claimed over 70 lives. The burden of arrests has also fallen disproportionately on the most vulnerable.
Of those arrested under the prohibition law, 67% were from SC, ST, and OBC communities. “You will never hear a rich person getting arrested for flouting prohibition because they drink in the comfort of their homes. It is the poor who face police action. The worst victim of prohibition is the marginalised community,” a critic of the law has noted. A former Chief Justice of India had also publicly criticised the law in December 2021, stating it lacked foresight and had led to an inundation of courts with liquor-related cases, crippling Bihar’s judicial administration.
The Logical Indian’s Perspective
What the Supreme Court is being asked to decide is not merely a legal technicality, it is a question about where the state ends and the citizen begins. Bihar’s prohibition law was born from a genuine and compassionate impulse: to shield women and families from the devastation that alcohol abuse can cause. That intent deserves respect. But good intentions are not a licence for disproportionate enforcement.
When police can knock on your door or walk through it, armed with a device that even the courts have repeatedly found to be inconclusive evidence, the protections that the Constitution guarantees to every Indian inside their home become fragile indeed.
The Supreme Court’s decision to examine the constitutional validity of the relevant provisions suo motu is a significant and reassuring signal that the judiciary will not let enforcement zeal override fundamental rights. Equally, the data demands an honest national conversation: a law that has led to over 1.4 million arrests, the overwhelming majority from the most marginalised communities, while hooch tragedies continue to claim lives, has clearly failed in its execution, even if not in its aspiration.
