Maharashtra Poisons Rules 1972 | Mandatory Addition Of Denaturants To Methanol Without Proportionality Analysis Violates Article 14 And 19(1)(g): Supreme Court

"The impugned rules fail to pass the test of proportionality, and result in violation of the fundamental rights guaranteed under Article 19(1)(g) of the non-drug manufacturers." Supreme Court, in a judgment dated September 18, 2026, struck down the 2011 amendment to the Maharashtra Poisons Rules, 1972, holding that the mandatory addition of bitterants and colourants to methanol was arbitrary, disproportionate, and violative of the fundamental rights of industrial consumers.

A bench comprising Justice J.B. Pardiwala and Justice K. Vinod Chandran observed that the state’s action imposed a "continuous burden on the industries" without establishing a "reasonable and proximate nexus" to the stated objective of preventing the misuse of methanol in illicit liquor.

The dispute arose following a 2011 notification by the Maharashtra Government, which amended the Maharashtra Poisons Rules to include Rules 18A and 18B. These rules mandated that any licensee selling methanol must verify the purchaser's license and, except for drug manufacturers, add specific quantities of methylene carmine (colourant) and denatonium saccharide (bitterant) to the substance. Various chemical manufacturers challenged these rules, arguing that the additives rendered the methanol unsuitable for industrial processes such as the manufacture of formaldehyde and life-saving drugs.

The central question before the court was whether the impugned Rules 18A and 18B were arbitrary, disproportionate, and violative of Articles 14 and 19(1)(g) of the Constitution. The court further examined whether the state had failed to adopt less restrictive measures to achieve the legitimate aim of preventing liquor tragedies.

State action fails the test of proportionality

The court conducted a rigorous proportionality analysis, acknowledging that while the prevention of hooch tragedies is a legitimate state aim, the means adopted must be balanced against the rights of the individuals affected. The bench observed that the restriction shifted an excessive burden onto industrial users while failing to address the unregulated channels through which methanol is diverted for illicit liquor production. The court noted that the state's approach was akin to "rearranging the deck chairs on the Titanic," as it addressed only the point of lawful sale rather than the systemic issues of pilferage and corruption.

Arbitrariness in the regulatory framework

The court emphasized that the requirement to verify a license in Form A for all purchasers was fundamentally flawed, as it ignored the diverse nature of industrial consumers who might not fall under the specific licensing regime but still required pure methanol. The judges pointed out that the Parthasarthy Committee Report had identified multiple causes for liquor tragedies, including corruption in law enforcement and the availability of cheaper alternatives, which the impugned rules completely ignored. The bench held that a policy that lacks rational justification or is marred by unreasonableness is liable to be struck down under Article 14.

Practical impossibility of the mandate

Regarding the addition of denaturants, the court highlighted that various industries, including those producing formaldehyde and chemical catalysts, provided evidence showing that the additives caused "loss of yield" and "reduced life of catalyst." The court found that the state failed to demonstrate that this additive practice would definitively prevent the consumption of spurious liquor, especially since miscreants could potentially mask the colour and flavour. Consequently, the bench concluded that the rules did not bear a reasonable nexus with the object they sought to achieve.

"What is discernable from the above is that in practicality, the impugned rules prescribe a regulatory framework that does not prevent the misuse of methanol in liquor which takes place in the unregulated field."

Directions for alternative measures

While striking down the rules, the Supreme Court provided extensive recommendations for the state to curb the menace of spurious liquor. These suggestions included the implementation of a multipronged approach involving the police, excise, and transport departments to monitor state borders and industrial units. The court suggested that instead of blanket additives, the state should focus on stricter inventory management, the use of dedicated tankers with tamper-evident seals, and more rigorous scrutiny of existing licenses. The bench emphasized that the primary responsibility lies with the police machinery to ensure that existing laws are implemented in letter and spirit.

The Supreme Court allowed the writ petitions and disposed of the civil appeal, declaring that Rules 18A and 18B of the Maharashtra Poisons Rules were unconstitutional. The registry was directed to forward copies of the judgment to all High Courts and Chief Secretaries of all states to encourage a more effective and less restrictive regulatory framework for the handling of hazardous chemicals.
