“A new fact will show that a miscarriage of justice has occurred when it so undermines the evidence against the defendant that no conviction could possibly be based upon it.”
“Where the fresh evidence is such that, had it been available at the time of the trial, no reasonable jury could properly have convicted the defendant.”
“Has the claimant established, beyond reasonable doubt, that no reasonable jury (or magistrates) properly directed as to the law, could convict on the evidence now to be considered?”
“Order, counterorder, disorder” is of the essence of good public administration. If the law is changed or suddenly discovered, it is right that it should be applied in its new form thereafter, but if it is to be applied retrospectively, this must be subject to some limitation. Quite what limitation should be applied would depend upon the particular circumstances. In the field of private law, retrospective action is controlled by the statute of limitations and the doctrine of laches. In the field of public law, it is controlled in the absence of any statutory provision by the exercise of the court’s discretion.”
“it would be quite impossible to suggest that a conviction for violent disorder in relation to an episode giving rise to a murder charge should not be a complete bar to compensation.”
