The Relative Chance of Paternity percentage is inadmissible in criminal proceedings because the raw percentage figures carry a real risk of misleading the jury, even where the Paternity Index ratio is admissible. Where DNA evidence is led, trial judges should consider directing the jury that the task before them is not capable of being reduced to a mathematical computation. The Prosecutor's Fallacy — treating the probability of the accused having the DNA profile as the probability of the accused being the offender — is an impermissible form of reasoning, and a warning may be required depending on the circumstances. Where the pool of suspects is exceptionally restricted, the difference between the permissible form of the evidence and the Prosecutor's Fallacy narrows, which is relevant to the application of the proviso.
