legal Definition of reasonable doubt
:a doubt especially about the guilt of a criminal defendant that arises or remains upon fair and thorough consideration of the evidence or lack thereof
- all persons are presumed to be innocent and no person may be convicted of an offense unless each element of the offense is proved beyond a reasonable doubt
- —Texas Penal Code
Note:
Proof of guilt beyond a reasonable doubt is required for conviction of a criminal defendant. A reasonable doubt exists when a factfinder cannot say with moral certainty that a person is guilty or a particular fact exists. It must be more than an imaginary doubt, and it is often defined judicially as such doubt as would cause a reasonable person to hesitate before acting in a matter of importance.
