The Supreme Court recently delivered a landmark 8:1 ruling, affirming the states' authority to regulate industrial alcohol.
This decision overturns a significant 1990 judgment in the Synthetics & Chemicals v. State of Uttar Pradesh case (1989), which had previously granted control to the central government.
This ruling is crucial for UPSC Mains GS-II (Polity & Governance), especially topics related to Centre-State relations and judicial interpretation of legislative lists.
The majority Constitution Bench expanded the definition of “intoxicating liquor” beyond just potable alcohol.
It clarified that this term encompasses all types of alcohol that can potentially impact public health negatively, not just alcoholic beverages.
The court emphasized that substances like alcohol, opium, and drugs are prone to misuse. It ruled that Parliament cannot override state powers concerning intoxicating liquors, as “intoxicating” can also mean “poisonous,” allowing for a broader classification.
Justice B.V. Nagarathna dissented, arguing against stretching Entry 8 – List II (State List) to include industrial alcohol merely due to its potential misuse.
She contended that allowing states to regulate industrial alcohol could lead to misinterpretations of the legislative intent behind alcohol regulation.
Industrial alcohol is essentially impure alcohol primarily used as an industrial solvent. It is rendered unfit for human consumption through a process called denaturation.
Denaturation involves mixing chemicals like benzene, pyridine, or gasoline with ethanol. This process significantly lowers its price and makes it dangerous to consume.
Applications:
Misuse: Despite denaturation, industrial alcohol is sometimes diverted to make illicit liquor, which is cheap, dangerous, and can cause severe health risks, including blindness and death.
The IDRA, 1951, provides the legal and conceptual framework for industrial development and regulation across India.
Main Goals of the Act:
