Ei Incumbit Probatio Qui Dicit: The Principle of Burden of Proof Explained

Definition & Meaning

The phrase "Ei incumbit probatio qui dicit" is a Latin term that translates to "the burden of proof rests on who asserts, not on who denies." This principle emphasizes that in legal matters, the responsibility to prove a claim lies with the person making the assertion, rather than the individual who disputes it. This concept is fundamental in many legal systems, particularly in criminal law, where it underpins the presumption of innocence until proven guilty.
