The Supreme Court on Monday refused to entertain a public interest litigation (PIL) seeking a directive to the Centre and oil marketing companies to ensure mandatory and uniform labelling of ethanol content on petrol dispensing nozzles and fuel receipts. A bench of Justices MM Sundresh and PB Varale dismissed the plea filed by advocate Narendra Kumar Goswami, granting him liberty to approach the jurisdictional High Court.

During the hearing, Goswami, appearing in person, argued that consumers have the right to know the composition of the fuel they purchase. He pointed to a petrol receipt and submitted, "See the receipt, there is no mention of ethanol. I have the right to know." He further contended, "Not only me but citizens at large should be informed about the composition of the fuel given to them."

Attorney General R. Venkataramani, appearing for the Centre, objected to the plea, describing it as "proxy litigation" and noting that a similar petition had already been dismissed by the court. "The petitioner wants Government of India to be answerable to him," the AG submitted. The bench, finding no merit in the petition, directed Goswami to raise his contentions before the High Court.

The petition sought several directions, including the prominent display of the exact ethanol percentage in local language on every dispensing nozzle at petrol pumps, and that every fuel invoice, bill or receipt clearly state the ethanol content. It also requested oil marketing companies to publish the ethanol percentage available at each retail outlet on their official websites and mobile applications.

Beyond labelling, the plea sought the creation of an official, public, vehicle-wise compatibility database searchable by manufacturer, model, engine type and year of manufacture, indicating the suitability of various ethanol blends for each vehicle. It also proposed the constitution of an independent expert committee, including representatives from the ministries of petroleum and natural gas, road transport and highways, the Bureau of Indian Standards and independent automobile engineers, to examine the real-world compatibility of E20 fuel with existing vehicles.

The committee was also asked to assess the impact of E20 on fuel efficiency, engine longevity, maintenance costs, warranty and insurance implications, emissions, water consumption in ethanol production and food-security concerns. The petition further sought a transparent transition framework for older or non-compatible vehicles, including the possible availability of lower-ethanol petrol where feasible, and a national consumer disclosure protocol for ethanol-blended petrol.

The E20 program involves blending 20% ethanol with petrol. The policy had earlier drawn attention when reports attributed to the Attorney General described it as an "experiment" in a previous hearing. The central government issued a clarification, saying such reports were "completely false," and stating: "At no stage was any submission made that the Government's Ethanol Blended Petrol (EBP) program or the E20 blending program is an 'experiment.'"

The Centre has repeatedly dismissed concerns that E20 fuel could affect the validity of vehicle insurance policies, with the oil ministry stating that such claims had been clarified with stakeholders and found to be incorrect. Separately, a district consumer disputes redressal commission in Raipur, Chhattisgarh, had ordered Maruti Suzuki to provide a new Grand Vitara with an E20-compatible engine to a customer whose vehicle broke down after alleged use of E20 fuel.
