A two‐stage test, under the Code for Crown Prosecutions, applied by a prosecutor when determining whether an offender is to be charged with an offence. The first stage is consideration of the evidence. If the case does not pass the evidential stage it must not go ahead no matter how important or serious it may be. If the case does pass the evidential stage, the prosecutor must proceed to the second stage and decide if a prosecution is needed in the public interest. See also threshold test.
