Question

What do you mean by 'onus probandi'?

• A. Burden of proof which places the responsibility on the party making an affirmative claim to substantiate it with evidence.
• B. The fact to be proved or the ultimate fact that needs to be established in a legal case.
• C. The prosecution in a criminal case must prove beyond a reasonable doubt both the act and the guilty mind.
• D. Actual evidence, documents, or witnesses presented to substantiate a claim.

Hint:

A simple way to remember this maxim is: ``Onus'' = Burden ``Probandi'' = To Prove Therefore, Onus Probandi means the legal burden of proving a claim before a court of law.

Answer 1

The Correct Option is A

Think of a courtroom where a person says, this house is mine, or the accused committed this crime. Neither the judge nor the opposing party is required to disprove the statement automatically. Instead, whoever puts forward the claim carries the job of backing it up with proof, whether that is a sale deed, a witness, or a confession. That obligation to prove one's own claim is what "onus probandi" refers to.

The remaining three options describe other, separate ideas in evidence law: the specific fact that a case turns on, called the fact in issue, the level of certainty a criminal court needs before convicting, called proof beyond reasonable doubt, and the material itself that is placed before the court, such as documents and testimony. None of these describe who is responsible for proving a claim in the first place, which is the one thing "onus probandi" is about.

Since the phrase specifically fixes responsibility on the party making the claim, the correct option is the one describing the burden of proof resting on the party making an affirmative claim.

Answer 2

A useful way to separate these four options is to notice that they pair up naturally, two options describe procedural responsibility and standard, while the other two describe substantive content.

1. Burden of proof which places the responsibility on the party making an affirmative claim to substantiate it with evidence: this is about who must prove something, a question of responsibility, and it matches what "onus probandi" literally means, the burden of proving.
2. The fact to be proved or the ultimate fact that needs to be established in a legal case: this is not about responsibility at all, it is about the content of what is being argued over, commonly called the fact in issue, which is a separate concept from who must prove it.
3. The prosecution in a criminal case must prove beyond a reasonable doubt both the act and the guilty mind: this is about responsibility too, but it fixes a specific standard for one type of case, criminal trials, rather than stating the general rule that governs onus probandi across both civil and criminal proceedings.
4. Actual evidence, documents, or witnesses presented to substantiate a claim: like the fact in issue option, this is about substantive content, here the material used to prove a claim, not about who bears the duty to produce it.

Narrowing the field to the two responsibility options and then noticing that one of them is limited to criminal cases while the other states the general principle shows that the general burden of proof rule is the one that defines onus probandi.

Hence, the correct answer is Burden of proof which places the responsibility on the party making an affirmative claim to substantiate it with evidence.
