2.2
Such previous decisions are as a rule confirmed in two ways: by the authority of those who gave the decision and by the likeness between the two cases. As for their reversal, this can rarely be obtained by denouncing the judges, unless they have been guilty of obvious error. For each of those who are trying the case wishes the decision given by another to stand, since he too has to give judgment and is reluctant to create a precedent that may recoil upon himself.
2.3
Consequently, as regards the first two classes, we must, if possible, take refuge in some dissimilarity between the two cases, and two cases are scarcely ever alike in all their details. If, however, such a course is impossible and the case is the same as that on which the previous decision was given, we must complain of the negligence shown in the conduct of the previous case or of the weakness of the parties condemned, or of undue influence employed to corrupt the witnesses, or again of popular prejudice or ignorance which reacted unfavourably against our client; or else we must consider what has occurred since to alter the aspect of the case.
