Legal Admissibility of Satellite Evidence in Indian Courts

As satellite technology becomes more accessible, a critical question arises for landowners and legal professionals: Can satellite imagery be used as evidence in Indian courts? The answer is yes, but only when it is produced, preserved and presented in a way that satisfies the current statutory framework.

Important update. On 1 July 2024, the Bharatiya Sakshya Adhiniyam, 2023 (BSA) came into force and replaced the Indian Evidence Act, 1872. Electronic records are now governed by Sections 61–63 of the BSA. Section 63 replaces the old Section 65B and prescribes a new certificate. Any writing that still refers only to "Section 65B" is out of date.

The current legal framework

Two central pieces of legislation govern the admissibility of digital and satellite evidence in India today:

The Bharatiya Sakshya Adhiniyam, 2023

• Section 61 recognises electronic records as documents.
• Section 62 treats a properly produced electronic record as a primary document.
• Section 63 sets out how an electronic or digital record is admitted, including the requirement of a certificate (previously Section 65B of the 1872 Act).

Satellite imagery, when properly documented and preserved, qualifies as an electronic record and can be produced in evidence provided:

• A certificate under Section 63 of the BSA 2023 accompanies the record.
• The imagery is produced from a device or system that was operating properly.
• The data has not been altered between capture and production.

The Information Technology Act, 2000

The IT Act provides the broader framework for recognising electronic records, digital signatures and electronic authentication. It defines what an electronic record is and gives statutory footing to hash-based integrity checks and secure electronic records, which the BSA 2023 relies on.

Key requirements for admissibility

For satellite evidence to be accepted in court, the following conditions must be met:

1. Source authentication. The imagery must come from a recognised satellite data source, whether a government mission (for example, ISRO, or open programmes such as ESA Sentinel and NASA Landsat) or an accredited commercial provider.
2. Chain of custody. An unbroken, documented chain of custody from data acquisition to court presentation.
3. Integrity verification. Cryptographic hashing (for example, SHA-256) so that any subsequent alteration is provable.
4. Expert testimony. A qualified expert who can explain the imagery, the analysis methodology and its limitations to the court.
5. Section 63 certificate. A certificate under the BSA 2023 attesting to how the electronic record was produced and preserved.

Precedents and practice

Indian courts have accepted remote-sensing and satellite evidence in a range of matters, from environmental and land-dispute cases to boundary and revenue proceedings. Under the BSA, the underlying principle carries forward: an electronic record can be relied on if its origin, integrity and production are properly established.

Final admissibility and evidentiary weight, however, are always for the court to decide. Nothing described here is a substitute for legal advice.

How ShieldNex is designed to fit this framework

ShieldNex's Data Chain of Custody is designed to support the electronic-record requirements of the BSA 2023 and the IT Act 2000.

Integrity-checked ingestion

Every satellite image is hashed with SHA-256 at the moment of ingestion. If a single bit changes later, the hash no longer matches and the alteration becomes evident. This establishes that a record has not been altered since ingestion, it does not, by itself, establish that the imagery was correctly sourced or that a court will accept the analysis built on it.

Documentation aligned with Section 63

Our system automatically compiles the material typically needed for a Section 63 certificate under the BSA 2023: timestamps, source metadata, processing logs, hash values and integrity-verification records.

Provenance-preserving evidence packages

When evidence is needed, ShieldNex is designed to produce a package containing:

• Original satellite imagery with source and licence metadata
• Change-detection analysis with before/after comparisons
• Chain-of-custody documentation, including the reviewer's decision
• SHA-256 hash-verification records
• Expert analysis report

We describe this as provenance-preserving rather than court-ready. The distinction matters: we can control what the package records about its own production, but we cannot pre-empt a court's decision on admissibility or weight.

Practical implications for landowners

Understanding this framework means landowners can build their evidence base before a dispute, not during one. Monitoring land with proper documentation from day one creates a defensible record that can be produced in court if a dispute arises later.

The value of the technology is not the pictures. It is the pipeline around them, the sourcing, the hashing, the timestamps and the Section 63 certificate, that turns imagery into evidence.
