"That, in order to obviate the practice, there must be some miscarriage of justice or violation of some principle of law or procedure. That miscarriage of justice means such a departure from the rules which permeate all judicial procedure as to make that which happened not in the proper sense of the word judicial procedure at all. That the violation of some principle of law or procedure must be such an erroneous proposition of law that if that proposition be corrected the finding cannot stand; or it may be the neglect of some principle of law or procedure, whose application will have the same effect. The question whether there is evidence on which the Courts could arrive at their finding is such a question of law."
