Moral Certainty

Definition from Nolo’s Plain-English Law Dictionary

In a criminal trial, the reasonable belief (but short of absolute certainty) of the trier of the fact (the jury or judge sitting without a jury) that the evidence shows the defendant is guilty. Moral certainty is another way of saying "beyond a reasonable doubt." Because there is no exact measure of moral certainty, it is always somewhat subjective and based on the reasonable opinions of the judge and/or jury. (See also: reasonable doubt)
