​Indian Evidence Law – Bharatiya Sakshya Adhiniyam 2023-Burden of Proving Fact Especially Within Knowledge [Section 109]

1. Introduction
In judicial proceedings, there are situations where certain facts are exclusively or especially within the knowledge of a particular person. In such cases, it would be unreasonable and impractical to expect the opposing party to prove those facts. To address this difficulty, the Bharatiya Sakshya Adhiniyam, 2023 incorporates a special rule regarding the burden of proof under Section 109.

2. Statutory Provision under Section 109
Section 109 provides that:

• When any fact is especially within the knowledge of any person,
• the burden of proving that fact lies upon him.

This provision shifts the burden of proof only with respect to those specific facts that are peculiarly within the personal knowledge of a party.

3. Illustrations under the Section
The Act clarifies the application of this principle through illustrations:

• Illustration (a):
  When a person performs an act with an intention different from what the act and its surrounding circumstances ordinarily suggest, the burden of proving such special intention lies on that person.
• Illustration (b):
  If a person is charged with travelling on a railway without a ticket, the burden of proving that he possessed a valid ticket rests upon him, as this fact is especially within his knowledge.

4. Scope and Nature of Section 109
Section 109 is an exception to the general rule laid down in Section 104, which states that the burden of proof lies on the person who asserts a fact. This Section applies only where:

• The fact is pre-eminently or exceptionally within the knowledge of the accused or a particular party; and
• Proving such fact would be impossible or disproportionately difficult for the opposite party.

Importantly, this Section does not absolve the prosecution of its primary duty to prove the commission of an offence beyond reasonable doubt. It merely casts a limited burden on the accused to explain facts within his special knowledge, once the prosecution has established foundational facts.

5. Rationale of Section 109
The word “especially” signifies facts that are not merely within the general knowledge of a person, but facts that are peculiarly and exclusively known to him. The provision is designed to prevent failure of justice in exceptional situations where:

• The prosecution has proved circumstances pointing towards guilt; and
• Certain crucial links in the chain of events can be explained only by the accused.

If Section 109 were interpreted broadly, it would unjustly reverse the fundamental principle of criminal law by compelling the accused to prove innocence. Hence, courts apply this provision with caution and restraint.

6. Judicial Interpretation

• In Sidhartha Vashist @ Manu Sharma v. State (NCT of Delhi), the Supreme Court held that the whereabouts and possession of the weapon used in the offence were facts especially within the knowledge of the accused. His failure to give a proper explanation entitled the court to draw an adverse inference under Section 106 of the Indian Evidence Act (corresponding to Section 109 of BSA).
• In State of West Bengal v. Mir Mohammad Omar, the accused had abducted the deceased, and the victim was later found murdered. The Court held that once abduction was proved, the accused alone knew what happened to the deceased thereafter. Their failure to explain justified drawing an inference of guilt under Section 109.
• Conversely, in Manharan Rajwade v. State of Chhattisgarh, the Supreme Court cautioned that Section 109 cannot be invoked unless the prosecution first establishes the foundational facts, such as the theory of “last seen together”. Since the prosecution failed to do so, the burden could not be shifted to the accused, and he was acquitted.

7. Doctrine of Reverse Burden / Reverse Onus
Section 109 embodies the principle of reverse onus, where the burden temporarily shifts to the accused to explain certain facts. However:

• This shift occurs only after the prosecution has discharged its initial burden;
• The provision does not compel the accused to prove innocence;
• It merely calls upon the accused to explain facts within his exclusive knowledge.

Failure to offer a reasonable explanation may permit the court to draw an adverse inference, but conviction cannot rest solely on this presumption.

8. Conclusion
Section 109 of the Bharatiya Sakshya Adhiniyam 2023 strikes a careful balance between the rights of the accused and the interests of justice. While reaffirming the principle that the prosecution must prove guilt beyond reasonable doubt, it recognizes that certain facts can be proved only by the person who has special knowledge of them. Applied cautiously, this provision prevents concealment of truth and ensures that justice is not defeated by technical impossibilities of proof.
