Understanding Affirmati Non Neganti Incumbit Probatio: The Burden of Proof Explained

Definition & Meaning

The phrase "the burden of proof is upon him who affirms, not on him who denies" is a legal principle that establishes who is responsible for providing evidence in a dispute. In legal contexts, the person making a claim (the affirmer) must provide sufficient evidence to support their assertion. This principle is crucial in both criminal and civil cases, where the party making the claim must prove their case to avoid dismissal.

Real-world examples

Here are a couple of examples of abatement:

Example 1: In a civil lawsuit for breach of contract, the plaintiff must provide evidence that the defendant failed to fulfill their contractual obligations. If the plaintiff fails to do so, the case may be dismissed without the defendant needing to present their own evidence.

Example 2: In a criminal trial for theft, the prosecutor must prove the defendant's guilt beyond a reasonable doubt. If they cannot meet this standard, the defendant is presumed innocent and may be acquitted. (hypothetical example)
