(February 2009) </Td> </Tr> <P> Reasonable doubt is a term used in jurisdiction of common law countries . Evidence that is beyond reasonable doubt is the standard of evidence required to validate a criminal conviction in most adversarial legal systems . </P> <P> Generally, prosecutors bear the burden of proof and are required to prove their version of events to this standard . This means that the proposition being presented by the prosecution must be proven to the extent that there could be no "reasonable doubt" in the mind of a "reasonable person" that the defendant is guilty . There can still be a doubt, but only to the extent that it would not affect a reasonable person's belief regarding whether or not the defendant is guilty . Beyond "the shadow of a doubt" is sometimes used interchangeably with beyond reasonable doubt, but this extends beyond the latter, to the extent that it may be considered an impossible standard . The term "reasonable doubt" is therefore used . </P>
