Definitions for "Beyond reasonable doubt"
The standard of proof in criminal matters, ie it must be proved beyond reasonable doubt that a person has committed an offence before they can be convicted. This is higher than the civil standard of proof which is the "balance of probabilities".• Criminal Courts
This is the level of proof required in all criminal matters. It means that there is no reasonable doubt in the decision makers mind, that the offence happened.
In a criminal case the guilt of the accused must be established "beyond a reasonable doubt." Proof beyond a reasonable doubt is proof that leaves you with an abiding conviction that the charge is true.
