1.20.10 Presumption of Innocence; Burden Of Proof; Reasonable Doubt
The defendant is presumed to be innocent until proven guilty. The defendant enters
upon the trial of the case with a presumption of innocence in his her favor. This
presumption remains with the defendant until it is overcome by the State with
evidence that is sufficient to convince you beyond a reasonable doubt that the
defendant is guilty of the offense charged.
No person shall be convicted of any crime unless and until each element of the
crime as charged is proven beyond a reasonable doubt. The burden of proof rests
upon the State to prove every material allegation of the indictment and every
essential element of the crime charged beyond a reasonable doubt.
There is no burden of proof upon the defendant whatsoever, and the burden never
shifts to the defendant to introduce evidence or to prove innocence. When a
defense is raised by the evidence, the burden is on the State to negate or disprove it
beyond a reasonable doubt.
However, the State is not required to prove the guilt of the accused beyond all
doubt or to a mathematical certainty. A reasonable doubt means just what it says. A
reasonable doubt is a doubt of a fair-minded, impartial juror honestly seeking the
truth. A reasonable doubt is a doubt based upon common sense and reason. It does
not mean a vague or arbitrary doubt but is a doubt for which a reason can be given,
arising from a consideration of the evidence, a lack of evidence, or a conflict in the
evidence.
