Unit IV — Burden of Proof, Presumptions & Estoppel

“He who would have the court act on a fact must prove it — but the law sometimes presumes a fact, shifting the burden to the one who would deny it.” — the logic of burden and presumption

Burden of Proof

The burden of proof is the obligation to prove a fact. The BSA distinguishes the burden of proof on the pleadings (which is fixed and never shifts) from the onus of adducing evidence (which shifts as evidence comes in).

In a criminal case the prosecution must prove guilt beyond reasonable doubt, and the accused’s mere denial casts no burden on him; but where a fact is especially within his knowledge (S.109) — e.g. how the deceased died in his sole company — the onus of explanation may shift to him.

A presumption is an inference the court draws. “May presume” is discretionary; “shall presume” is mandatory but rebuttable (the court must presume until the fact is disproved); “conclusive proof” is irrebuttable. Key presumptions: legitimacy of a child born during a valid marriage (S.116, ← IEA S.112 — conclusive unless non-access is shown); the dowry-death presumption (S.118, ← IEA S.113B) and the abetment-of-suicide presumption (S.117, ← IEA S.113A).

Estoppel (S.121, ← IEA S.115) prevents a person who, by his declaration, act or omission, has intentionally caused another to believe a thing to be true and to act on that belief, from later denying its truth in a suit between them. It is a rule of evidence, not a cause of action, and bars only the person estopped — including a tenant’s estoppel from denying the landlord’s title at the start of the tenancy (S.122) and the estoppel of a licensee/acceptor (S.123).

✏️ Sample Solved Problem (IRAC Method)

Problem: A woman dies an unnatural death within seven years of marriage after being harassed for dowry; the husband is charged. On whom does the burden lie and what presumption applies?

I — Issue

What presumption arises in a dowry-death prosecution, and where the burden of proof lies.

R — Rule

Section 118 (← IEA S.113B) — where a woman dies otherwise than under normal circumstances within seven years of marriage and was shown to have been subjected to cruelty or harassment for dowry soon before her death, the court shall presume that the accused caused the dowry death. (Section 117 raises a discretionary presumption of abetment of suicide in like circumstances.)

A — Analysis

The decoy is the ordinary criminal-law axiom that the prosecution must always prove everything — so the husband can simply stay silent. But S.118 is a “shall presume” provision: once the prosecution establishes the foundational facts — death otherwise than normal, within seven years, preceded by dowry-cruelty soon before death — the court is bound to presume the husband caused the dowry death, and the onus shifts to him to rebut that presumption. His silence then tells against him. The presumption is mandatory but rebuttable: he may displace it by showing, e.g., the death was natural or unconnected to dowry demands.

C — Conclusion

The court shall presume the husband caused the dowry death under S.118, the foundational facts being present; the burden shifts to the husband to rebut the presumption.
