Maryland Pattern Jury Instructions-Criminal (MPJI-Cr)
2:02 Presumption of Innocence and Reasonable Doubt
The defendant is presumed to be innocent of the charges. This presumption remains throughout every stage of the trial and is not overcome unless you are convinced beyond a reasonable doubt that the defendant is guilty.
The State has the burden of proving the guilt of the defendant beyond a reasonable doubt. This burden remains on the State throughout the trial. The defendant is not required to prove [his] [her] innocence. However, the State is not required to prove guilt beyond all possible doubt or to a mathematical certainty. Nor is the State required to negate every conceivable circumstance of innocence.
A reasonable doubt is a doubt founded upon reason. Proof beyond a reasonable doubt requires such proof as would convince you of the truth of a fact to the extent that you would be willing to act upon such belief without reservation in an important matter in your own business or personal affairs. If you are not satisfied of the defendant’s guilt to that extent, then reasonable doubt exists and the defendant must be found not guilty.
