1. Legal Position of Fuel Invoices as Evidence

Under the Indian Evidence Act, 1872:

• A fuel invoice is a document under Section 3.
• It may be treated as primary documentary evidence (Section 61–62) if original.
• Its relevance depends on Section 7 (facts forming part of same transaction) and Section 11 (relevant facts).

However, courts consistently hold:

A single document like a fuel receipt cannot by itself conclusively establish movement unless corroborated.

2. Evidentiary Value in Proving Travel Route

Fuel invoices may help establish:

• Presence of vehicle at a particular location/time
• Approximate travel direction (based on station location sequence)
• Consumption pattern supporting distance travelled
• Consistency with claimed route in litigation (custody disputes, insurance fraud, employment travel claims)

But courts require:

• Chain of movement evidence
• Authentic issuance of invoice
• Link between vehicle and person
• Absence of manipulation or fabrication

3. Judicial Principles & Case Laws (6+ Authorities)

1. State of Bihar v. Radha Krishna Singh (1977) 3 SCC 288

• Supreme Court held that documentary evidence must be proved in accordance with law and cannot be accepted on mere production.
• Old or unsupported documents have weak evidentiary value.
  Relevance: Fuel invoices alone are not reliable unless properly proved and linked.

2. Narbada Devi Gupta v. Birendra Kumar Jaiswal (2003) 8 SCC 745

• Court held that mere marking of a document as exhibit does not prove its contents.
• Execution and authenticity must be established.
  Relevance: A fuel bill must be proved by issuing authority or system records, not just submission.

3. State of Maharashtra v. Dr. Praful B. Desai (2003) 4 SCC 601

• Recognised modern methods of proof and technological evidence.
• Emphasised flexibility in evaluating electronic and documentary proof.
  Relevance: Fuel invoices linked with digital billing systems or card swipes gain stronger probative value.

4. Anvar P.V. v. P.K. Basheer (2014) 10 SCC 473

• Landmark ruling on electronic evidence.
• Held that electronic records must comply with Section 65B certification.
  Relevance: If fuel invoice is generated electronically (fleet card, app-based billing), compliance with electronic proof rules is essential.

5. Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020) 7 SCC 1

• Reaffirmed strict requirement of Section 65B certificate for electronic records.
• Clarified admissibility conditions for digital documents.
  Relevance: Digital fuel receipts without proper certification may be inadmissible.

6. Tomaso Bruno v. State of U.P. (2015) 7 SCC 178

• Court stressed importance of scientific and objective evidence like CCTV and digital records.
• Adverse inference can be drawn if best evidence is withheld.
  Relevance: Courts may prefer fuel invoices combined with GPS/CCTV over oral claims.

7. Bharat Singh v. Bhagirathi (1966) AIR 1966 SC 405

• Held that admissions and documentary evidence together strengthen proof.
  Relevance: Fuel invoices gain strength when consistent with admissions or travel records.

4. How Courts Evaluate Fuel Station Invoice for Route Proof

Courts generally apply a “corroboration test”:

(A) Consistency Test

• Does fuel timing match claimed travel route?

(B) Chain-of-events Test

• Multiple invoices across different locations showing logical movement.

(C) Authenticity Test

• Verified GST invoice / system-generated bill.

(D) Supporting Evidence Test

• GPS logs, toll receipts, FASTag data, CCTV, witness testimony.

5. Common Judicial Findings

Courts usually hold:

• Fuel invoices = supportive evidence
• Not sufficient alone to prove exact travel route
• Strong only when part of combined digital + documentary chain

6. Practical Legal Conclusion

A fuel station invoice showing travel route is treated as:

• ✔ Secondary corroborative evidence
• ✔ Useful for establishing probability of movement
• ❌ Not conclusive proof of entire route

Its strength increases significantly when:

• linked with GPS/FASTag data,
• issued from authenticated systems,
• consistent across multiple records,
• supported by witness or digital surveillance evidence.
