It is vital to all that British Justice reflects Natural Justice and is even-handed and fair and is seen to be even-handed and fair. Such stacking of the cards in favour of the prosecution is totally against natural justice.
As soon as possible restore the double jeopardy rule. If a case cannot be made against an idividual or individuals sufficient to convince a jury of their guilt. Then that should be the end of the matter. There cannot be a situation that the prosecution can keep re trying untill they get the the answer they like. it is a rediculous distortion of justice. Unless there is convincing and profound new evidence that was unavailable previously and even then that would have to be persuasive. this 'best out of three' situation is a disgrace.
