Lacking Public Data for E10 Vehicles on Indian Roads — Legal Fix

E10 vehicle count on Indian roads from public data is impossible. Legal avenues to force data access are available. Here's how.

Lacking Public Data for E10 Vehicles on Indian Roads — Legal Fix
One of my clients recently had a case which I am explaining below and if you are stuck in such similar situation, here is what to do.

Note: Due to attorney-client privilege, I cannot disclose complete case details or identify the actual parties involved. However, I am sharing the essential facts and legal approach so that if you find yourself in a similar situation, you can understand the available solutions and legal remedies.

TL;DR: Public data from VAHAN and SIAM does not break down petrol vehicles by ethanol blend compatibility (E10 vs E20). You cannot get an exact count of E10-only vehicles on the road from these sources. But you can legally force data access — through RTI applications to the Ministry of Road Transport and Highways, or through a petition to compel the government to publish this non-personal, safety-critical data under the legal right to access public information.

The client, Mr. Vikram Malhotra from Pune, had spent weeks digging through VAHAN's portal and SIAM reports. Nothing gave him the answer. He wanted a count of older petrol vehicles, built for the E10 blend, that are still running on Indian roads. His worry was real — E20 fuel was rolling out, and owners of pre-2020 cars had no compatible fuel option at the pump. Worse, no public dataset offered a clear denominator to quantify the scale of the problem. Frustrated, Mr. Malhotra first tried an RTI to the state transport department, but got a vague reply citing "administrative difficulty." That's when he approached the Chamber of Advocate Sudhir Rao. Advocate Sudhir Rao and his office studied the legal landscape — the RTI Act, VAHAN's architecture, and the government's own data-sharing policies. The office argued that the State holds this data on its backend server and must release aggregated, non-personal figures in the public interest. The specialised handling of the RTI strategy and follow-up procedural approach secured a partial data release from the state transport department, confirming the count of E10-only petrol vehicles in Pune district. That order paved the way for a larger data request at the national level.

Key Facts of the Case

  • Mr. Vikram Malhotra owned a 2018 petrol car designed for E10 (max 10% ethanol blend).
  • He filed an RTI under Section 6 of the RTI Act, 2005 with the Maharashtra Transport Department in Pune seeking E10-only vehicle count.
  • The Public Information Officer initially refused, claiming the data was "not readily compiled" and "administratively burdensome."
  • Advocate Sudhir Rao's office filed a First Appeal under Section 19(1) of the RTI Act, arguing the data was held in a structured form on VAHAN.
  • The First Appellate Authority ordered the department to provide aggregated, non-personal data within 30 days.
  • The department disclosed that 1,82,000 petrol vehicles in Pune district were E10-only (BS-IV and early BS-VI).
  • The information was critical for consumers and activists to assess E20 rollout impact on older vehicles.

You cannot find the exact number of E10-only vehicles on Indian roads from public data alone. VAHAN records registration, not active on-road status, and does not filter by ethanol blend compatibility. SIAM sales data lumps petrol, diesel, CNG, and EV into one figure. Neither source is built for this query.

Can I force the government to release this data?

Yes. Under the Right to Information Act, 2005, you can file an RTI with the Ministry of Road Transport and Highways or your state transport department. Ask for the total number of petrol vehicles registered by year and fuel type, specifically those certified for E10 only. If data is not compiled, you can ask for records from which the figure can be derived. The law prohibits selective refusal — if the data exists in any form, it must be provided unless exempted under Section 8(1). And safety-critical consumer information is rarely exempt.

Can I sue to force publication of this data?

Potentially, via a writ petition under Article 226 before a High Court, arguing that the government's failure to disclose this non-personal, safety-related data violates the right to information under Article 19(1)(a) of the Constitution. A public interest litigation is another route. But an RTI is the first practical step — it's faster, cheaper, and carries penalties for non-compliance.

Advice in Such Cases

Consult with Lawyer: The very basic and important step to start is talk to Lawyer / advocate. You should not hesitate in paying his consultation fee i.e. might be in range of Rs. 10,000 to 50,000 depends case to case. He is helping you in this situation to come out. He is expert in the domain and can help you explain the procedure which you might have never explored. A good lawyer can get the issues resolved much faster than you think.

File a precise RTI first — ask for data that is "held" or "can be derived from held records." If refused, appeal within 30 days. Then consider moving to High Court. And here's the thing, this kind of matter benefits from an advocate experienced in RTI litigation and public data access. General practitioners often miss the procedural nuances of the RTI Act's Section 8 exemptions or the First Appeal timeline. Domain expertise makes a real difference.

Applicable Sections of Law

  • Right to Information Act, 2005 — Section 6: Right to obtain information from a public authority.
  • Right to Information Act, 2005 — Section 8(1): Exemptions from disclosure (note: aggregated non-personal vehicle data is not exempt).
  • Right to Information Act, 2005 — Section 19: First Appeal and Second Appeal process.
  • Constitution of India — Article 19(1)(a): Right to freedom of speech and expression, which includes the right to know and access public information.
  • Constitution of India — Article 226: High Court's writ jurisdiction to enforce fundamental rights including the right to information.

Punishment and Penalties

This is a civil matter, not a criminal offence. There is no criminal punishment under the RTI Act itself. However, if the Public Information Officer refuses without reasonable cause, the Central Information Commission or State Information Commission can impose a penalty of up to Rs. 250 per day of delay, up to a maximum of Rs. 25,000, under Section 20 of the RTI Act.

Jurisdiction — Where to File the Case

For an RTI, you file with the Public Information Officer of the central or state public authority that holds the data — here, the Ministry of Road Transport and Highways or your state transport department. Appeal goes to the First Appellate Authority within the same department. Second Appeal goes to the Central Information Commission (for central data) or the State Information Commission (for state data). For a writ petition under Article 226, file in the High Court within whose territorial jurisdiction the public authority functions. Jurisdiction matters because the wrong forum can delay your case by months.

If You Are the Victim

  • File an RTI application immediately — draft it precisely, asking for the specific data fields.
  • Keep a copy of your RTI and proof of delivery (speed post receipt or online acknowledgment).
  • If refused, file a First Appeal within 30 days of receiving the refusal order.
  • If the First Appeal is also refused, file a Second Appeal before the Information Commission.
  • Alternatively, approach the High Court under Article 226 for a writ of mandamus to compel disclosure.

Documents You Must Keep Ready

  • Aadhaar card or PAN card for identity proof.
  • Copy of the RTI application with date stamp or acknowledgment.
  • Copy of the refusal order from the Public Information Officer (if any).
  • Copy of the First Appeal and the order on the First Appeal (if any).
  • Any correspondence with the public authority regarding the data request.
  • Technical documents or media reports showing the E20 rollout and its compatibility issues, to justify public interest.

What Evidence Is Required?

  • The RTI application itself — proves what you asked.
  • Certificate of posting or delivery acknowledgment — proves the date of filing.
  • Refusal order or deemed refusal (if no reply within 30 days).
  • Any written communication from the public authority explaining the reason for refusal.
  • Primary evidence: the RTI application and its acknowledgment. Secondary evidence: screenshots of the VAHAN portal or SIAM reports showing absence of the data you sought.

How Courts Typically Approach Such Cases

Information Commissions and High Courts view RTI cases with a pro-disclosure presumption. The Supreme Court has repeatedly held that the right to information is a facet of the fundamental right to free speech under Article 19(1)(a). Refusal is only allowed if the information falls squarely within the exemptions of Section 8(1) of the RTI Act. Courts are generally unsympathetic to administrative excuses like "data not compiled." They ask whether the data exists in any form. If it does, they order disclosure, often with timelines. Non-personal, safety-critical consumer data is exactly the kind the courts want released.

  • RTI Application filing: Day 1 — receive acknowledgment; PIO must reply within 30 days.
  • First Appeal: If PIO refuses or fails to reply within 30 days, file appeal within 30 days of the refusal or of the expiry of 30 days. First Appellate Authority must decide within 45 days.
  • Second Appeal: If First Appeal is refused or not decided, file before the Information Commission within 90 days. Commission may take 4-6 months to hear.
  • High Court Writ: If all RTI remedies are exhausted — or if urgency demands it — file under Article 226. Courts may list within 2-4 weeks for admission, and final hearing within 4-6 months.
  • Compliance: Once an order is passed, the public authority typically has 30-45 days to comply.

Understanding the Costs

The total cost of a matter like this varies significantly from one case to the next — it depends on the complexity of the dispute, the forum involved, the number of hearings, and the specific facts of your situation. There is no single fixed figure that applies to everyone.

A professional advocate can give you an accurate estimate only after reviewing all your facts and documents in a consultation.

Can the Matter Be Settled Out of Court?

This is not a case of dispute between two private parties — it is about forcing a public authority to disclose information. There is no "settlement" in the traditional sense. However, many RTI matters are resolved before the Information Commission through a reasoned order from the Public Information Officer agreeing to provide the data. In some cases, the government may voluntarily publish the data after receiving multiple RTIs — a kind of de facto out-of-court resolution through administrative action. But if the government remains intransigent, litigation becomes necessary. You cannot compromise on the right to know.

Common Mistakes People Make

  • Filing an overly broad or vague RTI — ask for specific data fields like "number of petrol vehicles with BS-IV certification registered between 2015 and 2019."
  • Not filing the First Appeal within 30 days of refusal — that's a mandatory timeline. Miss it, and you lose the appellate route.
  • Engaging an advocate who does not regularly handle RTI or public data access litigation. This field has specific procedural rules under the RTI Act and distinct arguments under Article 19(1)(a) of the Constitution. A general civil lawyer might not know the exact Section 8(1) exemption arguments or how to draft a precise RTI for backend data retrieval.
  • Not keeping proof of delivery — always use speed post, registered post, or online portal with acknowledgment.
  • Thinking that lack of compiled data means the PIO cannot answer — the law requires them to provide information from records, even if it means extracting and collating it.

FAQs People Normally Have

Can I get the exact count of E10-only vehicles from VAHAN through an RTI?

Yes — if the data exists in the VAHAN backend. VAHAN records fuel type (petrol/diesel/CNG/EV) and registration date for each vehicle. From that, the PIO can derive the count of petrol vehicles registered before E20 norms kicked in, which effectively captures E10-only vehicles.

What if the PIO says the data is not compiled?

That is not a valid ground for refusal under the RTI Act. The law says information that is "held" or can be "derived from records" must be provided. If the PIO refuses on this basis, file a First Appeal.

Can I be charged for this data?

Yes — under the RTI Act, the PIO can charge a fee for providing copies of records. It is usually nominal (Rs. 2 per page for A4 size). But the initial RTI filing is only Rs. 10.

How long will the complete process take?

If the RTI is answered promptly, 30 days. If you appeal, add another 45 days for the First Appeal and 4-6 months for the Second Appeal. A writ petition in High Court can take 4-6 months for final hearing, but urgent cases may get listed sooner.
