The Cyclopedic Law Dictionary
To establish a fact to a reasonable certainty requires that degree of proof of certainty which the jurors would be willing to act upon in their own grave and important concerns; that is, the degree of proof should be such that the fact is established beyond a reasonable doubt. "A reasonable doubt" and "reasonable certainty" and "moral certainty" mean one and the same thing.
