The law of evidence deals entirely with the proof of facts. Under Section 2(1)(f) of the Bharatiya Sakshya Adhiniyam (BSA), 2023 (corresponding to Section 3 of the old IEA), a "fact" is structured into a dual juristic classification encompassing both physical and psychological elements: (Internal / Subjective)

Statutory Illustrations:

1. Physical Facts: That there are certain objects arranged in a certain order in a room; that a man heard or saw something; that a man said certain words; or that a physical scar exists on a victim's body.

2. Psychological Facts: That a man has a certain reputation; that a man holds a specific fraudulent intention; that a person acted in good faith; or that a person possesses malice towards a rival.

II. Fact in Issue vs. Relevant Fact

Understanding the boundary between these two concepts is the most vital threshold requirement for trial advocacy:

1. Fact in Issue [Section 2(1)(g) BSA / Old Sec. 3]

A "fact in issue" (popularly called the principal fact or factum probandum) means any fact from which, either by itself or in connection with other facts, the existence, non-existence, nature, or extent of any right, liability, or disability, asserted or denied in any suit or proceeding, necessarily follows.

Trial Court Reality: In civil matters, facts in issue are formalized when the judge frames the "Issues" under Order XIV of the Code of Civil Procedure, 1908. In criminal matters, they form the core contents of the "Charge" framed under Chapter XVIII to XXI of the BNSS, 2023.

2. Relevant Fact [Section 2(1)(j) BSA / Old Sec. 3]

A fact is said to be relevant to another (popularly called the evidentiary fact or factum probans) when the one is connected with the other in any of the ways referred to in the provisions of the BSA, 2023 relating to the Relevancy of Facts (Sections 4 to 50).

a. The Principle of Legality: Under Indian law, a fact cannot be admitted into the record merely because it is logically convincing. It must be legally relevant, meaning it must comfortably fit into at least one of the specific statutory windows under Chapter II of the BSA (such as Res Gestae, Motive, Alibi, Admissions, Confessions, or Expert Opinions).

III. The Three Judgments of Court: Proved, Disproved, and Not Proved (Section 2(2))

At the conclusion of a trial, a judge must evaluate each material fact and arrive at one of three statutory conclusions:

1. Proved [Section 2(2)(a) BSA / Old Sec. 3]

A fact is said to be proved when, after considering the matters before it, the Court either:

a. Believes it to exist, or

b. Considers its existence so highly probable that a prudent man ought, under the circumstances of the particular case, to act upon the supposition that it exists.

c. Standard of Proof: Driven by Preponderance of Probabilities in civil disputes, and Proof Beyond a Reasonable Doubt in criminal trials.

2. Disproved [Section 2(2)(b) BSA / Old Sec. 3]

A fact is said to be disproved when, after considering the matters before it, the Court either:

a. Believes it does not exist, or

b. Considers its non-existence so highly probable that a prudent man ought, under the circumstances of the particular case, to act upon the supposition that it does not exist.

3. Not Proved [Section 2(2)(c) BSA / Old Sec. 3]

A fact is said to be not proved when it is neither proved nor disproved. It represents a state of judicial baseline equilibrium where the party bearing the burden of proof has failed to tip the scales of evidence in either direction.

IV. The Statutory Degrees of Presumptions (Section 4)

Presumptions are legal deductions or inferences that the law mandates a judge to draw regarding the existence of a fact without requiring immediate underlying proof. Section 4 of the BSA, 2023 provides three strict hierarchical degrees of presumptions:

1. May Presume (Discretionary Presumption of Fact)

Whenever it is provided by the BSA that the Court may presume a fact, it means the Court holds full judicial discretion. The Court may either:

a. Regard such fact as proved, unless and until it is disproved, or

b. May call for independent, formal proof of it first.

c. Juristic Status: These are Presumptions of Fact (Presumptiones Hominis).

They are always rebuttable, temporary, and can be safely ignored by the judge if human experience dictates otherwise.

Example: Under Section 119 BSA (old Sec. 114), a court may presume that a man in possession of stolen goods soon after the theft is either the thief or has received the goods knowing them to be stolen.

2. Shall Presume (Mandatory Presumption of Law)

Whenever it is directed by the BSA that the Court shall presume a fact, the Court loses all judicial discretion. The Court must regard such fact as proved, unless and until it is successfully disproved by the adverse party.

Juristic Status: These are Rebuttable Presumptions of Law (Presumptiones Juris Tanturn). The judge is statutorily bound to start with the presumption, but must allow the opposite side an opportunity to adduce evidence to overthrow it.

Example: Under Section 118 BSA (old Sec. 113A), when a married woman commits suicide within seven years of marriage, and it is shown her husband subjected her to cruelty, the court shall presume such suicide was abetted by the husband.

3. Conclusive Proof (Irrebuttable Presumption of Law)

When one fact is declared by the BSA to be conclusive proof of another, the Court shall, on proof of the one fact, regard the other as proved, and shall not allow evidence to be given for the purpose of disproving it.

Juristic Status: These are Irrebuttable Presumptions of Law (Presumptiones Juris et de Jure). They represent absolute legal finality. The moment the foundational fact is proved, a statutory shutter falls down, and the court is prohibited from entertaining any contrary evidence whatsoever.

Example: Under Section 114 BSA (old Sec. 112), the birth of a child during the continuance of a valid wedlock is conclusive proof of legitimacy, unless it can be conclusively shown that the parties had no physical access to each other at any time when the child could have been begotten.

V. Comprehensive Juristic Matrix: Presumptions of Fact vs. Law

To assist in formulating appellate briefs and trial submissions, the table below maps out the core structural differences between the two primary classes of presumptions:

Analytical Parameters	Presumptions of Fact / Natural (May Presume)	Presumptions of Law / Artificial (Shall Presume)
Juristic Source	Derived dynamically from the laws of nature, logic, human experience, and common sense.	Derived strictly from express statutory legislations and provisions of the Act.
Judicial Discretion	Highly Discretionary. The judge is completely free to accept or reject the inference.	Mandatory baseline. The judge has no option but to automatically adopt the presumption.
Stability of Status	Variable and weak; it instantly vanishes the moment any positive contrary evidence is produced.	Firm and legally binding; it holds the ground unless systematically disproved by a high standard of evidence.
The Factor of Notice	The court can completely ignore these presumptions, forcing the asserting party to prove the fact from scratch.	The court cannot ignore them; the initial burden of proof automatically leaps over to the opposite side to break it.
