Presumptions are judicial shortcuts, not judicial guesses. Evidence law recognises that proving every fact by direct evidence is often impossible. To prevent trials from becoming unworkable, the law permits courts to assume certain facts once foundational facts are established.
But here’s the hard truth many miss: presumptions do not eliminate proof; they shift the burden of proof. If you don’t understand that, you don’t understand presumptions.
Meaning
A presumption is a legal inference or assumption that the court is permitted or required to draw from certain proved facts.
In simple terms, when fact A is proved, the law allows or compels the court to presume fact B—unless the presumption is rebutted.
Presumptions exist to balance practicality with fairness.

Why it exist?
Evidence law is not built for perfection; it is built for reasonable justice.
Presumptions exist because:
- Direct evidence is not always available
- Certain facts follow natural human conduct
- Some situations involve unequal access to evidence
- Endless proof would paralyse trials
However, presumptions are carefully controlled because they affect the burden of proof.
Classification
Under evidence law, it is broadly classified into three categories:
- May presume
- Shall presume
- Conclusive proof
Each has a different legal effect.
“May Presume”
When the law says the court may presume a fact, it grants judicial discretion.
The court is free to:
- Presume the fact, or
- Call for proof of that fact
This type of presumption is rebuttable and flexible. The court weighs surrounding circumstances before deciding whether to rely on it.
“May presume” reflects caution and common sense.
“Shall Presume”
When the law says the court shall presume a fact, the court must draw the presumption once the foundational facts are proved.
However, this presumption is still rebuttable. The opposing party is entitled to disprove it by leading evidence to the contrary.
This shifts the evidential burden, not the ultimate legal burden.
“Shall presume” is mandatory—but not irreversible.
“Conclusive Proof”
Conclusive proof is the strongest and most dangerous category.
When the law declares a fact to be conclusive proof of another fact:
- The court must accept it
- No evidence to the contrary is allowed
Rebuttal is legally barred, even if the truth appears otherwise.
This is not a presumption in the ordinary sense; it is a legal fiction created in the interest of certainty.
Because it overrides factual truth, courts interpret conclusive proof provisions very strictly.

Presumptions of Fact vs of Law
Of Fact
These arise from human experience and logic. Courts infer facts based on natural conduct, habits, and probabilities.
They are discretionary and rebuttable.
Of Law
These are created by statute. Courts are bound to apply them once conditions are satisfied.
They may be rebuttable or conclusive, depending on legislative intent.
In Criminal Cases
In criminal law they are applied with extreme caution.
Criminal jurisprudence is built on:
- Presumption of innocence
- Proof beyond reasonable doubt
Any presumption that shifts the burden onto the accused is treated as an exception, not the rule.
Even where statutory presumptions exist, the prosecution must first establish foundational facts. Blind reliance on presumptions is unconstitutional.
In Civil Cases
Operate more freely in civil cases.
Since civil liability is based on probability, presumptions play a larger role in resolving disputes efficiently.
Once a presumption arises, the burden shifts to the opposing party to rebut it on a balance of probabilities.
Rebuttal of Presumptions
Most presumptions are rebuttable.
Rebuttal does not require proof beyond doubt. It requires credible evidence sufficient to:
- Create doubt
- Displace probability
- Undermine the presumed fact
If rebuttal succeeds, the presumption collapses.
Presumptions vs Proof
Presumptions do not replace proof; they restructure it.
Proof establishes the base fact.
Presumption fills the logical gap.
Rebuttal tests the assumption.
Confusing presumptions with proof leads to lazy arguments and bad judgments.
Importance
Presumptions:
- Prevent evidentiary deadlocks
- Promote efficiency
- Address imbalance of access to evidence
- Reflect social and legal realities
But they are dangerous if applied mechanically.

Presumptions under evidence law are tools of necessity, not convenience. They exist to aid justice, not to bypass it.
A presumption is never the end of inquiry—except where the law expressly makes it conclusive.
Good lawyers know when a presumption arises.
Great lawyers know how to destroy it.
